After you have measured the width, cut the belt in half, either directly down the middle or along the tape joint. Dzurenda, L., Orlowski, K., and Grzeskiewicz, M. (2010). The results are provided in in Table 6 and Fig. A longer sanding time is associated with a lower removal rate, which results in sanding belt wear. Solid lines correspond to model results at the highest pressure (oak at 14700 Pa and beech at 18600 Pa). On the other hand, a chip generated at low feed speeds develops low centrifugal force, filling the inter-chip space and choking the individual abrasive grit tips, thus reducing the removal rate (Ljubimov 1974). Feel free to get in touch for a quote when you next need sanding belts. 2022 Econaway Abrasives. Pogaj, A., Chovanec, D., Kurjatko, S., and Babiak, M. (1997). Popov (1965) expresses the sanding belt durability as the total length able to participate in sandingS(m) until the sanding belt is dulled, when the maximum removal rateZvs. feed speed ratio achieves 50% of the initial value. An example of this would be a 4" (wide) X 36" (length) as demonstrated in our video below. Process monitoring evaluation and implementation for the wood abrasive machining process,Sensors10(11), 10401-10412. Floor belt sanders are manually operated to sand wood floors. Next, measure the width of the belt. 2. Any solution increasing the sanding belt lifetime would benefit the wood industry by saving electricity, creating more sustainable sanding belts, and reducing the time needed for the sanding belts replacement. These measurements are presented as a function of the defined sanding time of 480 min on a manual sanding belt machine. Saloni, D., Lemaster, R., and Jackson, S. (2005). Laurov, M., Vbohov, E., and Mamoov, M. (2007). The pictures shown are for a 1 x 30 long belt. 2. In the case of atool that cannot be re-sharpened, the durability and lifetime are identical. 3/ Slowly roll the belt through a full rotation until the mark is once again touching the flat surface. In addition to the sanding time, a high-quality sanding belt is characterized by the amount of removed material. Sanding belt pressure on the piece surface (6600, 10400, 14700, and 18600 Pa), sanding direction (cutting speed vector with reference to wood fibers equal to 0, 60 and 90), wood hydrothermal treatment, and sanding belts from various manufacturers were the variables. Oak is a ring porous wood species with significant density differences between spring and summer rings; the hard summer wood forestalls the penetration of the sanding grit particles into the spring wood. Table 2. Gurau, L. (2004). Research in this field is important to determine the processed piece quality, sanding belt performance, and electricity consumption (Pahlitzsch 1970; Stewart 1976; Matsumoto andMurase 1999; Saloniet al. The influence of interface pressure on wood removal rate with a sanding belt running time of 480 min and sanding direction 60. 1/ Press the belt down and measure from end to end, double measurement and you have your length. European beech (Fagus sylvaticaL.) and English oak (Quercus robur) were chosen as the test materials. A Common question we get is how can I figure out what size belt I need for my sander! Furthermore, its grit features an electrostatic open-coated surface, providing consistent dust removal for continuous sanding. Statistical Models for Individual Pressures. During wood processing, sanding is carried out with the purpose of pre-grinding, calibration, paint adhesion increase, fine grinding, and smoothing. This might load the sanding belt and reduce its lifetime, consequently breaking it. The blue curve represents the wood removal for sanding belt LS 309 XH for HT, and the solid line represents the modeled one. These measures extend the lifetime and reduce sanding costs by reducing the setting times, consumption of materials for the sanding belts cleaning, providing longer belt lifetime, and increasing material removal rate (Saloniet al. Experimentally obtained results were parametrically fitted by model (1). Heartwood and sapwood lipophilic extractives of oak (Quercus petraea(Mattusch.) The abrasive sanding of rubberwood (Hevea brasiliensis): An industrial perspective,Holz als Roh-und Werkstoff60, 191-196. Fig. The highest removal rate values for the oak were achieved at the highest selected pressure (14700 Pa); however, the wear curve of the sanding belt was plotted in the interval from 0 to 80 min only. A lesser degree of cellular element cutting takes place during longitudinal sanding. Measuringtools.co.ke 2022. Measuring a sanding belt incorrectly can be expensive, especially if they are a custom made belt. Star curves represent experimentally obtained results for oak wood samples, whereas circle curves represent experimentally obtained results for beech wood samples. These (mainly in case of sanding alongside the fibers), as well ascvalues, were greater for beech. 19 01979.5.1968. The influence of variants (natural and hydrothermally treated beech, 2 kinds of belts) on wood removal rate sanding belt running time 480 min, interface pressure 14700 Pa, sanding direction 60. A temperature range of 50f - 80f degrees is. Taylor, J. Comparison of Sanding Belts Performance, Table 5. Up to a certain degree, this was also confirmed in the first phase of the wear curve. For both wood species, the removal rate decreased with time. Ratnasingam, J., Reid, H. F., and Perkins, M. C. (1999). The experiments utilized equipment designed for monitoring of contact phenomena (Porankiewiczet al. JavaScript seems to be disabled in your browser. Measure the LENGTH of the belt from end to end. 3. A Radwag WPS 510/C/2 digital lab scale with an accuracy class of 0.001 g (Jakarta, Indonesia) was used to determine the sample mass before and after sanding. The diagrams in Fig. 1. Abrasive machining is an important investment because the sanding belt per-unit price is high, and the abrasive belt lifetime is short. The sanding direction, with other constant conditions (pressure), significantly affected the removal rate values. They come in a range of types that include: Regardless of which machine you use, applying the right sanding belt is essential for performance. 2010), which was based on a Bosch GBS 100 AE manual sanding belt machine (Robert Bosch GmbH, Gerlingen, Germany). Thecvalue of the removal rate until its stabilization remained approximately equal for each of the three variants. Thus, not only the wood species (Pahlitzsch, 1970), but also its anisotropic properties play a very significant role in the interaction with the tool. Article submitted: February 19, 2016; Peer review completed: April 12, 2016; Revised version received and accepted: April 21, 2016; Published: April 28, 2016. The former becomes more fragile, with altered physical properties; the analyzed chip, sawdust and/or particles of the resulting dust are smaller than in the case of the same processing methods on natural wood. Temperature and humidity are the two most important factors influencing coated abrasive performance. Content of respirable and inhalable fractions in dust created while sawing beech wood and its modifications,Drewno58(194), 135-146. The curve has three typical phases (Pahlitzsch 1970). Address: 380 Sheldon Drive, Unit 7/8 Hlskov, L., Rogozinski, T., Dolny, S., Kopeck, Z., and Jedink, M. (2015). We will order again.Thank you, What if there was an easier and affordable way to keep your lines looking crisp and your workplace c, If you want your workspace to be at its maximum efficiency and functionality, youve got to prioriti, The original phrase 'Don't cry over spilt milk' is defined bydictionary.com as 'It doesn't do, Worldwide Shipping. Properties of used Endless Sanding Belt. The check measurements of the sanding belt performance were carried out at 20-min intervals, using three reference samples that were sanded for 1 min each. If you have no information and no existing belts its time to take a closer look at your sander. Abrasive machining process characterization on material removal rate, final surface texture, and power consumption for wood,Forest Products Journal55(12), 35-41. Contact us today to get started with your custom order or if you need help you finding what you need from our extensive online selection ofsanding belts. Acta Facultatis Xylologiae49(2), 17-23. Their content in beech wood have a volume between 22 and 37%. Stand der Forschung beim Schleifen von Holz,Holz als Roh und Werkstoff28(9), 333-343. The effects of wear on the performance of sanding belts were determined for European beech (Fagus sylvatica L.) and English oak (Quercus robur). The experiments demonstrated that the sanding belt lifetime during oak sanding was very low, not only as far as the sanding time was concerned, but also as far as the removal rate was concerned. Stewart, H. A. You can measure a brand new belt by easily first measuring the width, then laying the belt down as flat as possible without bending or creasing the belt in a way that will damage it, measuring from one end to the other, then DOUBLING the size as this is a belt and NOT a flat sheet in this instance. Slowly move the belt through a full rotation until the mark on the belt once again touches the surface, and then mark the touch point. 1999), sanding pressure on the processed piece at constant conditions (Pahlitzsch andDziobek 1959; Pahlitzsch andMeyer 1968; Kato andFukui 1976a,b; Stewart 1978; Matsumoto andMurase 1999; Tayloret al. Now lay it out linear and measure it end for end. 1. All Rights Reserved. Experimental modeling of the sanding process: the relationship between input and output parameters, in:Proceedings of the 14thInternational Wood Machining Seminar, Paris, France, pp. The first phase of sanding is deemed undesirable, as during its course, the sanding parameters are changing dramatically. What type of backing material will I receive if I order my belts on line? The effect of belt oscillation on sanding performance of belt sander,Journal of the Japan Wood Research Society22, 550-556. Ratnasingamet al. Varying these factors for specific sanding tasks should result in a higher quality of the resulting product, lower electricity consumption, and the maximum possible durability and lifetime of the sanding belt (Okajovet al. Stewart, H. A. To learn more about our abrasives or place an order, please call, Drum Sander Replacement Conveyor Feed Belts, Surface Conditioning (Non Woven Polishing). The libriform fibers are thick-walled cells. A significantly limit lower value of the removal rate based on a values was observed for oak compared with beech. Physical and mechanical properties of wood Test methods for small clear wood specimens Part 2: Determination of density for physical and mechanical tests, International Organization for Standardization, Geneva, Switzerland. The wood pores are thin-walled cells. If you have an older belt, cut it so that it turns into one long strip, then lay it flat and measure the total length. Based on this analysis, sanding belt wear was evaluated within the time range from 0 to 480 min (1 working shift) by the means of the wear curves. For any of the three sanding directions, the limit lower value of the removal rate dropped under 50% of the initial value. This will work with the longer belts as well as smaller belts, however it does require having a belt you can cut in half. The sanding belt wear can be expressed by a wear curve, which shows the reduction of material removal ratevs. sanding time. Dont worry we will help you figure it out. This measurement will give you your belt LENGTH. Pahlitzsch, G. (1970). Die Berechnung der optimalen Betriebsbedingungen fr die Arbeit von Schleifmaschinen,Industrial Wood Processing14(4), 12-14. DOI: 10.15376/biores.10.4.7123-7135. Vergleichende Untersuchungen der Schleiffhigkeit und Wirtschafklichkeit von Schleifpapieren,Mettalloberflche6(4), 53-61. All rights reserved. Dulling increases the number of effective cutting wedges. Another way to get the dimensions you need is to take a piece of string or yarn (or any non-stretching material) and wrap it around the sander where the belt would go, making sure it is snug and not overlapped. After the binder crumbles, new abrasive grit begins to work; the tool contact area is regenerated continually. Matsumoto, H. A., and Murase, Y. For a myriad of reasons, you may have a belt sander youve acquired or stored for a while that is in need of a new belt, but youre not sure what size you need. (1999, 2002), who indicated that the increased material removal rate inevitably resulted in a temperature increase. Based on results of numerous studies (Hlskovet al. Option #3 Cut the existing belt in half and lay flat. (2010) estimated that atypical wide belt sanding abrasive machine costs $75 per h of processing, which is substantially more than knife machining. Now that the string is marked lay the string on a flat surface and measure the string with your tape measure. The performance of sanding belts LS 309 XH for both beech and oak sanding in function of the individual sanding angles (0, 60 and 90) for the sanding belt selected pressure 10400 Pa andsanding time of 480 min. 7125 Whites Bridge Rd | Belding, MI 48809. Sparky can custom make any size belt wide to 13 wide and up to 400 long. For the oak, these values were in higher orders, which entailed a shorter first phase (pressure of 6600 Pa and14700 Pa). Thus, the duration of the first phase for beech was shorter, and the sanding process was stabilized earlier, while passing into the second phase (working sharpness). Reach out to our abrasive technicians for a custom order quote. (2010), who emphasized that for the optimum performance of the sanding belt, the various sanding parameters as a function of the wood species should be considered. Okajov, A., Beljakov, A. and Siklienka, M. (2010). DOI: 10.15376/biores.10.2.3657-3665. In the second phase of working sharpness, the line is decreasing proportionally. Pahlitzsch, G., and Dziobek, K. (1959). DOI: 10.1007/BF02608663. To compute the regression function, a modified method of minimum squares was used. In this experiment, this occurred after 80 min at the pressure of 14700 Pa, and eventually after 240 min at 6600 Pa. Because beech is a key species for bent furniture fabrication, treated beech wood was also tested in the sanding experiments. Liebl.). https://www.rapidabrasives.ca/product/custom-sanding-belt-calculator/. In the first phase of initial sharpness, the wear curve has a digressively decreasing tendency. Kato, C.,and Fukui, H. (1976b). 2015; Dzurendaet al. Popov, J. P. (1965). al. Sanding is the most essential process operation for wood products before surface finishing. It is also ideal for flush sanding rebates and edges. Even if the sanding belt cannot be re-sharpened in the same way as tools with standard wedge geometry, it also can exhibit a certain capability of self-sharpening, that occurs after whole abrasive grit or particles are broken from the binder. A non-linear regression was used to process the results obtained for sanding belt wear at the individual sanding variants. The results are provided in form of statistical models in Table 4 and wear curves of the sanding belt in Fig. Radial samples with dimensions of 50 50 50 mm were made in amanner giving the angle between the cutting speed vector direction and the fibers orientation the angles of 0, 60, and 90. Often times european or asian belt sanders can have funky belt sizes that are not commonly stocked by distributors in the United States. If you find the size isnt available in our standard selection check out our custom belt calculator. Maverick Abrasives manufacturers custom sanding belts every day for customers with conventional or unconventional sanding belt machines. Both woods are important to the furniture industry due to their excellent physical and mechanical properties. Saloni, D., Lemaster, R., and Jackson, S. (2010). 2022 Red Label Abrasives. The resulting chip is smaller because it has low bending strength; the filling of the inter-chip space may become less intense. Those four methods are the double measurement method, the cut and measure method, the string method, and the rotation method. Red Label Abrasives sells a wide variety of sanding belts in a full range of different sizes. When measuring a sanding belt I always recommend this 5 step fool-proof method: 1/ Make a small mark on the inside of the belt with a pen or marker. DOI: 10.1007/s001070050026, Ratnasingam, J., Reid, H. F., and Perkins, M. C. (2002). When a belt freezes, the grain expands and contracts at a different rate as the backing and tape which allows the joint to become weak. 2005). If you dont have a belt to measure, you can use a piece of string. 2011). The dependence of surface quality on tool wear of circular saw blades during transversal sawing of beech wood,BioResources10(4), 7123-7135. Stationary belt sanders can be bench-mounted, pedestal-mounted, or even mounted on a stand. For beech, the belt did not break and was fit for further use; for oak, the belt was broken. As one triplet of samples was not sufficient for all check measurements during 480 min, various triplets were made. For the best experience on our site, be sure to turn on Javascript in your browser. Sanding belts come in many widths and many lengths so getting the most precise measurement for your belts is absolutely necessary when it comes time to re-order your sanding belts. Ex Tax: KES 365.94, Distributors of surveying, Measuring, Testing, Power & Hand Equipment. In general, wear can be described as gradual and small changes in geometry of machining tools or abrasive grit, which cause the reduction of its ability to cut effectively (Kminiaket al.

Then make a corresponding mark on the floor or a flat surface like a counter or benchtop. Thecvalue gives the removal rate drop until stabilization takes place. The sanding belt pressure (Klingspors LS 309 XH) on the sanded piece (beech, oak) was optimized as a function of the sanding time of 480 min and sanding direction under a 60 angle to the wood fibers. Once you have the right sanding belt size, the next step is to find a reputable supplier of premium quality abrasives. (2011) considers the sanding belt load and the belt lifetime as the critical variables of sanding, suggesting a sanding belt check system including optical (loading), temperature (safety), and acoustic emission (belt life) sensors. A wear curve throughout the entire monitored interval was plotted for oak and sanding angle of 0; for 60, it was plotted within the interval from 0 to 460 min. 73-82. (2014). It takes a certain amount of time to stabilize the process and enter into the second phase: that of working sharpness, which should be as long as possible, as far as the sanding tool durability (lifetime) is concerned. If your belt is smaller, press it down flat on a hard surface and measure it from end to end using a tape measure or string. The obtained values were converted to specific removal rate (g.cm-2.min-1). 2005). Sometimes this requirement causes issues, especially if youre using someone elses sander or it has been a while since you had to change belts. DOI: 10.1007/s00107-002-0285-1, Rogozinski, T., Wilkowski, J., Grski, J., Czarniak, P., Podziewski, P., and Szymanowski, K. (2015). Dust creation in CNC drilling of wood composites,BioResources10(2), 3657-3665. 2011). The X440 Best for Wood and Paint removes material at an excellent rate when sanding old paint, varnish or wooden surfaces. 653-662. Common sanding belts sizes include: Don't see the size you need on our site? Double the length and youll have a good idea of the belt size you require. Despite the wear curve for oak at pressure of 1.04 N.cm-2having been plotted for 460 min, it was only after 240 min that the minimum removal rate was equal to 0.025 g.cm-2.min-1and the subsequent sanding belt breaking was observed. 3/ The String Method. In the third phase, dulling, the curve has a strongly progressive tendency for decrease. Samples from this timber were formed in a manner identical to those from natural wood. The wood species had a significant impact on the sanding belt wear (for both removal rate and sanding time). The wear curve for the sanding belt at the pressure of 18600 Pa was plotted for the interval from 0 to 420 min. These are your belt dimensions, and they will help you shop for a replacement. The dulling occurs due to the breaking of abrasive grit with unfit orientation. 1, which show the removal rate dropvs. time for all monitored pressures for beech and oak. Treatment and Measuring Parameters. Specific resistance and All Rights Reserved. Solid lines correspond to model results at sanding direction 90; dash lines correspond to model results at sanding direction of 60. Kminiak, R., Gapark, M., and Kvietkov, M. (2015). If you were measuring using method one you might not have gotten this precise measurement and instead rounded up or down, which could cause issues on your machine. Aside from these basic features, the sanding performance is also affected by the sanded material type (various wood species and materials), sanding direction (which influences the resulting chip shape with rounded edges or very articulate chips forming clusters (Okajovet al. It does what was advertised. The experiment outcomes are the statistical models and wear curves for the sanding belts for the selected sanding variants. Should you be unsuccessful, the team at. This product is intended for the sanding wooden and coated surfaces, and is suitable for smoothing out feather edges. Sanding belts are measured Width x Length x grit followed by the material/grain you will be sanding with. If you no longer have a hard copy, most manuals can be found on the manufacturers website. Pahlitzsch, G., and Meyer, H. R. (1968). There was a great difference in the performance of the 2 types of sanding belts with identical input parameters. The store will not work correctly in the case when cookies are disabled. Statistical Models for Individual Sanding Angles, Fig. If you dont know the correct belt dimensions for your belt sander, there are four quick and easy methods you can use to determine the correct belt size. If you no longer have a hard copy, most manuals can be found on the manufacturers website. 1. Fig. There are several difficult / inaccurate ways that are commonly used to measure them. For example 3 x 21 80 Grit Aluminum Oxide is a common sanding belt sold at any hardware store. A wear curve throughout the entire monitored interval was plotted for beech and sanding angle of 60. 2. Start by trying to locate the product manual, which should indicate the correct belt size. The pressures of 14700 Pa and6600 Pa for the oak were deemed inappropriate as far as the sanding time is concerned as well as from the point of view of the removal rate value. Sign up for our newsletter to receive specials and up to date product news and releases. Canada. The exhaustion was carried out by Rowenta exhauster into single-use paper bags. Wrap a piece of string around the belt, cut where the two ends meet, lay the string flat and measure. Mrakov, E., Krik, L., Kuerka, M., Gaff, M., and Gajtanska, M. (2016). Beech is a dispersed-pore wood species with uniform structure in the spring and summer rings. Efficiency of Sanding Belts for Beech and Oak Sanding, Alena Okajov,aMartin Kuerka,aLubo Krik,bIvan Ruiak,band Milan Gaffc. The effects of wear on the performance of sanding belts were determined for European beech (Fagus sylvaticaL.) and English oak (Quercus robur). We are proud to offer these products direct to consumers with our Red Label Line. Statistical Models for Individual Variants. Your email address will not be published. Double this number and that is the length of your belt. Ex Tax: KES 192.60, KES 424.49 2016). Part of the beech timber underwent hydrothermal adjustment in the Buina Zvolen factory. Creation of wood dust during wood processing: Size analysis, dust separation, and occupa-tional health,BioResources11(1), 209-222. Ex Tax: KES 41.73, KES 74.47 KES 48.41 These results showed that the sanding direction (even despite the sanding belts oscillation) had a great impact on the removal rate value. Their content in the beech wood is under average,i.e., from 37 to 44%. As far as the typical wear curve for the sanding belts is concerned, in no case was the third phase, that of dulling (when the curve tends to drop sharply) achieved, since the belt use was terminated in the second phase, that of working sharpness, after either the sanding time of 480 min elapsed (the belt was viable for further use) or the belt was broken before the selected time. Make sure your cut is straight, because youre now going to measure it lengthwise. Second grab a tape measure and a piece of string. For the beech sanding, the limit lower value never dropped below 50% of the original removal rate value. Based on statistical models, great differences between the a removal rate values for beech and oak can be observed. The resulting curves for the sanding belts, as well as the statistical models of the wood removal rate, decreased as a function of the sanding time, described by the function y = a + b.ect. 2 show the removal rate drop as a function of time for each monitored variant. Verfahren und Vorrichtung zur Ermittlung der Kornverteilung an Schleifwerkzeugen,DBP. Some of your belts have directional arrows on the back. Please reach us through WhatsApp for any queries or questions. Simultaneously, the results obtained for the oak sanding confirmed the conclusions of Ratnasingamet al. Firstly if you have your sanders manual take a look there for the correct sanding belt size, chances are it will be a common sized belt you can find in our standard belt selections, click here. If youre scratching your head because your sander doesnt have an old belt to remove and measure, no worries. For oak, the duration of the first phase was longer for each sanding angle than for the beech; the transition to the second phase was gradual but with great drop in removal rate. Saloniet al. A pressure of 10400 Pa was selected to allow the wear curve comparison in function of the sanding angle for both beech and oak. There are a couple of different ways to determine the correct belt size to fit your machine. whereyis the wood removal rate,a+bis the initial removal rate,ais the limitary removal rate,bis the removal rate drop from initial to limit lower value,cis the removal rate drop speed from initial to limit lower value, andtis the sanding time (min).
