POSITIONING A PIECE PART TO THE DISC FACE
No matter what size or type piece part you will be sanding or grinding, there are several
important points to consider.
1. Always be sure that the wheel guard is positioned over the disc edge. Dust and grit removed
from the piece part can be hurled off the wheel if the wheel guard is not in position.
IMPORTANT:
Always allow time for the disc to come up to full speed before
contacting the piece part to the disc.
2. This is a very powerful and aggressive grinding device which operates at high surface
speeds so you always want to properly support the piece part while using the work table.
3. The safest position at which to do any grinding is with the part on the work table where the
disc is moving
downward past the work
table. Whenever
possible, keep the
workpiece in this area
when grinding. In
addition to safety,
keeping the piece part in
this area greatly
increases the
effectiveness of the dust
control chute and any
vacuum dust control
system you might be
using.
4. The speed and aggressiveness of the machine means that CONTROL of the piece part is
absolutely essential.
ALWAYS USE TWO HANDS
to control the piece part.
5. Because of the speed with which the disc can grind, heat build-up on piece parts is usually
very quick. To prevent burns and/or possible loss of control of any piece part:
a. Use heat resistant gloves to hold the piece part.
b. Where possible and appropriate, use additional tooling or fixturing to hold the
workpiece when pressing against the grinding disc.
WARNING:
All machinery poses a potential for danger when being
operated. Accidents result from lack of machine knowledge and failure to pay
attention. Always be cautious and alert to the potential for serious injury. Follow
safety rules and precautions to lessen the chances of an accident.
