66. s Basic Operation The basic operating procedure for the DDS 225 is as follows 1 gt depth of cut Start drums Start conveyor and select feed rate Start dust collector system Feed stock through unit Determining depth of cut is one of the most important procedures for the sander It may take some experimentation to determine the proper depth of cut given the variables of abrasive grit type of wood and feed rate For best results use scrap wood to practice sanding and to develop skill and familiarity with the machine before doing finish work A good rule of thumb when sanding with grits finer than 80 is to lower the drum so it contacts the workpiece but drum can still be rotated by hand When using grits coarser than 80 grit you can lower the drum slightly more However a combination of several variables will determine the proper depth of cut to use including the following O Abrasive type and grit size O Width of the piece being processed O Hardness of the piece Feed rate of the conveyor belt Stock Feeding Angle Some pieces because of their dimensions will need to be fed into the machine at a 90 angle perpendicular to the drums However even a slight offset angle of the stock will provide for more effective stock removal The optimum feeding angle is about 60 Fig 20 Angling the workpiece for stock removal provides other advantages such as less loading of certain
67. sander Variations in paper type weight coating and durability all contribute to achieving your desired finish Ready To Cut strips are available from WMH Tool Group and are listed on page 38 As with any sanding operation first begin sanding with a coarser grit depending on the roughness of the stock or the amount of stock to be removed Then progressively work toward finer grits This means if you are using two different grits on your DDS 225 dual drum sander the coarser grit should always be placed on the front drum The amount of stock to be removed is a major consideration when choosing the grit grade to start with Grits 36 and 60 are primarily designed for stock removal grits over 100 are primarily finishing grits designed to remove the scratch pattern from the previous grit used For best results never skip than grit grade when progressing through a sanding sequence For fine work such as furniture try not to skip any grit grades during the sanding process In general premium quality abrasives will produce a better finish with a less noticeable scratch pattern ACAUTION Grits that are too fine can sometimes burnish the wood and leave a glossy surface which will not accept stains evenly This will vary by type of wood Oak for example is susceptible to burnishing because of its open pores Cleaning abrasive strips Regularly clean the abrasive strips on the drums with commercially availabl
