Sanding Roll
Mounted on hold for rubber
wheel (9)
Full speed
22,000/min
Metal
Mild steel
Note:
To fit the sanding roll, firstly loosen the small screw on top of the hole
for rubber wheel, this will allow the rubber to relax. Slide the sanding
roll onto the holder.
To secure, simply tighten the screw and the rubber roll will swell,
gripping the sanding drum.
3. SPEED SETTINGS
To aid you in determining the optimum operational speed for different materials and different
accessories, we constructed below chart. By this table, you can discover the recommended speed for
some type of accessory.
Ultimately, the best way to determine the correct speed for work on any material is to practice for a
few minutes on a piece of scrap, even after referring to the chart. You can quickly learn that a slower or
faster speed is more effective just by observing what happens as you make a pass or two at different
speeds. When working with plastic, for example, start at a slow rate of speed and increase the speed
until you observe that the plastic is melting at the point of contact. Then reduce the speed slightly to get
the optimum working speed. Some guidelines regarding tool speed:
1) Plastic and other materials that melt at low temperatures should be cut at low speeds.
2) Polishing, buffing and cleaning with a with a wire brush must be done at speeds not greater than
15000/min to prevent damage to the brush and your material.
3) Wood should be cut at high speed.
4) Iron or steel should be cut at high speed. If a high speed steel cutter starts to vibrate, it usually
indicates that it is running too slow.
5) Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various speeds, depending
on the type of cutting being done. Use paraffin (not water) or other suitable lubricant on the cutter
to prevent the cut material from adhering to the cutter teeth.
Note:
Increasing the pressure on the tool is not the answer when it is not performing as you think it
should. Perhaps you should be using a different accessory, and perhaps an adjustment in speed would
solve the problem.
