Blade
The support blade in common is 60
∘
. There is more wear in the part of
frequenet contact on workpiece due to the load of grinding resistance.
Gernerally, blade is welded with super-hard wolfram shell; sometimes high
speed steel is used. The thickness of blade should be smaller than exernal
diameter of workpiece. 1/2 to 1/6 of diameter of workpiece plus center height
of grinding wheel or regulating wheel is the cener height of grinding piece. If
the height of support blade is insufficient, packing plate should be used to
achieve the required height. The thickness of support blade is shown on chart
below.
