5.3.1 How to selecting suitable wheel
The wheel have tiny grain which is sharp and rotating at high speed, and
cutting variable kinds of material.
The mainly basic factor is as following
(1) Abrasive —— the cutter
(2) Bond —— make these grains one piece and could turn safely at a
high speed.
(3) Air hole —— the space between these grains, which could expel the
chip and have good processing surface.
All above factor form a whole wheel, it have these chapter as following:
(1) As the cutter, the grain is harden than the work piece, it can process
the tool steel and hard alloy steel, too.
(2) The passivated grains will fall off then the new grains appear.
(3) The grain is tiny and hard, using it can obtain good surface and
accuracy.
