Buffing
machine （AUGUST 2, 2006 - UL 1581）
420.6 A
power-driven buffing machine (grinding wheel) is appropriate for buffing
irregularities from the samples from which die-cut specimens are to be
prepared. The abrasive wheel is to be of about No. 36 grit (particle size of
0.019 inch or 0.486 mm). The wheel is to run true and is not to vibrate. The
diameter of the wheel is not specified; however, 4-3/4 – 6-1/4 inch or 0.12 –
0.16 m has been found appropriate. The rotary velocity of the wheel is to be
2500 – 3500 r/min. The diameter and rotary velocity of the wheel are to be
selected to give the wheel a peripheral speed (rpm×p×wheel diameter) of 3000 –
5000 ft/min or 15 – 25 m/s. CAUTION – The maximum wheel diameter stated in this
paragraph and the maximum wheel rpm stated in this paragraph shall not be used
together as this combination will result in a peripheral speed above 5000
ft/min or 25 m/s. This applies even for wheels that are marked as being
intended for a peripheral speed above 5000 ft/min or 25 m/s. The machine is to
have a slow feed that applies light pressure and removes very little material
at one cut, thereby not overheating the specimen or the wheel.
