Stock Feeding Angle

The optimum stock feeding angle, when sanding, is at a 60-degree angle. However, even a slight stock feeding angle will provide more effective stock removal, less loading of abrasives, longer abrasive life, potentially faster feed rates and reduced motor loads.

When finish sanding, the work piece should be fed through in line with the grain on the final one or two passes for the optimum finish.

Multiple-Piece Sanding Runs

When abrasive planing (or thickness sanding) a run of similar pieces that you want to have the same thickness, it is best to sand all the pieces at the same time. This way you will be able to determine the thickness of the thinnest piece and process all pieces to that same thickness. Be aware that the sander will remove cups and crowns in the work piece; consider this when measuring the processing stock to the same thickness.

Edge Sanding

When edge sanding, the Performax sander will mimic the opposite edge of the stock which is lying on the conveyor belt. Because of this, it is important for the stock edge to have been ripped at the proper angle to the face before the sanding process. When edge sanding stock that is less than 3/4” wide, or more than 2” high, it is

good procedure to stack and clamp several pieces together to prevent them from slipping, or tipping.

Sanding Imperfect Stock

When sanding stock with a cup or crown, place the crown up. This will stabilize the stock to help prevent tipping or rocking during sanding. (After the crown has been removed and the top is flat, turn the stock over and sand the opposite side.) To avoid personal injury, take special care when sanding stock that is twisted, bowed or otherwise varies in thickness from end to end. If possible, support such stock as it is being sanded to keep it from slipping, or tipping. Use extra roller stands, help from another person, or hand pressure on the stock to minimize potentially hazardous situations.

Face Frames and Raised Panel Doors

It is very important to have the proper abrasive contact when doing this type of sanding. If the sander 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, make sure that when using abrasives finer then 80 grit, the drum is in contact with the wood but can still be spun by hand.

Monthly Maintenance

For best results, perform the following recommended maintenance procedures on a monthly basis:

•Lubricate the conveyor bushings and check for wear.

•Lubricate all moving parts, such as threaded rods, washers and bushings.

•Clean the sawdust from the conveyor belt and sanding drum.

•Blow the dust from the motors and switches. Blow the dust from the inside of the sanding drum to prevent vibration. Be careful not to disturb the drum balancing weights.

•Check all the setscrews for tightness on parts such as bearings, the conveyor and couplings.
