customer himself.
1-5 The Use of Emery Cloth in Metal Processing Can Cause Danger
In all accidents occurred on the lathe, most are from the use of emery cloth to cause
breakage of fingers, or even to amputate occasionally.
When workpieces with different shapes are rotating on the lathe, if using emery
cloth to deburr, to polish or to process finished sizes, it can cause the accident when
winding emery cloth on the workpiece to be ground by two hands. If winding the
emery cloth on the finger or to make rough grinding, the finger could be seized firmly
to cause serious injury.

Operation Manual of Horizontal Lath

Precautions
The operator should have certain recognition and knowledge on the necessity to
treat part by emery cloth on the lathe.
It is not needed to process by emery cloth in following cases:
If the requirement of the surface roughness is not so high;
Make processing by turning or on special polisher or grinding machine, the finished
sizes and surface roughness can be achieved well.
If technological rule defines that the workpiece should be ground by emery cloth,
then the emery cloth should be used in following cases:
a. Nail the emery cloth on a quality wood board to grind;
b. The emery cloth is fixed on and jigged by the tool holder to grind.
c. The “Robust Grinder” consists of two pieces of jointed wood board and the
emery cloth to make grinding and the workpiece to be polished can go through its
hole.
d. The polish is made by the wire brush stuck with abrasive material.
Apply force at
the both ends of
