14. rate control of the conveyor belt adjuststhe load on the machine it can be infinitely adjusted for maximum operating performance A faster feed rate allows faster sanding but fewer revolutions of the drums per inch of sanding A slower feed rate provides more revolu tions of the drum per inch of sanding to allow a greater depth of cut and smoother sanding T he SandSmart control See Fig 15 continuous ly monitorsthe load on the drum motor and auto matically regulates the speed of the conveyor motor to maintain the highest feed rate without overload If theload on the drum motor increases the SandSmart control will decrease the conveyor feed rate and will stop the conveyor under extreme con ditions If the load on the drum decreases the SandSmart control will increase the feed rate but WILL NOT increaseit faster than the manual set ting on the switch dial For abrasive planing and thicknessing the feed rate can be set at any speed after adjusting for the proper depth of cut If theload on the drum motor approaches its optimum dueto inconsistent stock the feed rate will automatically dow down As the load on the drum motor decreases the feed rate will automatically increaseto its original setting W hen finish sanding with gritsfiner than 80 the best finish will be achieved if the conveyor does not change speeds during operation W hilethe SandSmart control will slow the feed rate when the main motor reaches its optimum it is adv

TMENT H ANDLE INL s Fig 13 SUPERM Ax operating controls SETTING THE DEPTH OF CUT Adjusting the Su PERM ax for the proper contact between the abrasive and the stock determines the mechanical depth of cut Determining the depth of cut is the most important set up procedure before operating the Su PERM Ax sander It may take some experimentation to determine the prop er 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 fin ish work A good rule of thumb when sanding with grits finer than 80 isto raise the conveyor table so the drum s contacts the workpiece but still can be rotated by hand W hen using grits coarser than 80 grit you can raise the conveyor table slightly more H owever a combination of several variables will determine the proper depth of cut to use includ ing thefollowing 1 Abrasivetype and grit size 2 Width of the piece being processed 3 H ardness of the piece 4 Feed rate of the conveyor belt If your SuPERM Ax isa single drum model the depth of cut is controlled by the table height adjustment handle which raises or lowers the con veyor table under the drum If your machineisa dual drum version the depth of cut of the primary drum is also adjusted by thetable height adjust ment handle On dual drum units the d
28. ace Frames amp Raised Pand Doors It is very important to have the proper abrasive contact when doing this type of sanding If the machine is set to take an excessive depth of cut the result can be a gouge or dip as the drum goes from sanding the rails at full width to sanding just a few inches of width on the stiles To prevent this problem for example make sure that when using abrasives finer than 80 grit the drum is in contact with the wood but can still be spun by hand If there is room angling the stock on the conveyor belt can also help Slowing the conveyor feed when coming to a rail in the stock can help prevent a dip or gouge T his allows the abrasive to work the wider width with less effort and to achieve better consistency of the finished surface Stock Feeding Angle Some pieces because of their dimensions will need to be fed into the machine at a 90 angle perpendicular to the 18 SUPERM AX OWNER SMANUAL drums H owever even a slight offset angle of the stock will provide for more effective stock removal T heoptimum feeding angle for stock removal is about 60 see Fig 17 Angling the workpiece for stock removal provides other advantages such as less loading of certain areas of the drums due to glue lines or mineral streaks in the stock more even wear of abrasive strips potentially faster feed rates and lighter loads on the motor N ote that to get the best final finish however the stock should befed thr
