หินเจียรราบ (Surface Grinding Wheels)

Surface Grinding Wheels
The geometric shape of surfaces produced by methods included in this category is essentially flat. While the designation "flat surface grinding" would be more appropriate, expressing more precisely the purpose of the process, the shop usage of the term is so widely accepted that "surface grinding" is generally considered to imply the grinding of flat surfaces. The grinding of flat surfaces may be carried out either with the periphery or with face of the grinding wheel.

Surface Grinding Wheels (Straight type)
Surface grinding with straight or recessed wheels on machines with a rotating or reciprocating table results in larger contact area than in cylindrical grinding. Therefore, it is necessary to use softer grade wheels, particularly when large diameter and/or wide wheels are used.

When Grinding a large number of components, the grinding is not continuous. In this case, the components tend to dress the wheel, so a harder grade wheel should be used.

For all type of tool steel
