●粗料度的磨料适用于磨削:

●Use Coarse Grit:

1)材质较软,延伸率大以及类似软铁和有色金属等

1.for soft,ductile,stringy material such as softsteel

and nonferrous material

2)进给量大,磨削速度要求高的场合.

2.for rapid stock removal,high grinding speed

3)表面粗糙度要求不高的场合.

3.where finish is not important

4)磨削接触面大的场合.

4.for large areas of contact

●细粒度的磨料适用于磨削:

●Use Fine Grit:

1)硬度较高以及类似高碳工具钢,硬质合金钱类的金

1.for hard,brittle materials such as hard tool steels,

属材料和玻璃等脆性材料.

cemented carbide and glass.

2)表面粗糙度及精度要求高的场合.

2.for fine finishes

3)磨削接触面小的确场合.

一般砂轮硬度选择的原则是:

based on the grinding parameters such as feed rate.

should be followed with regard to grade

●较软的硬度

●Use Soft Grade:

1)进刀量大的粗磨.

1.for rapid stock removal

2)磨削接触面大的场合.

2.for large greas of contact

3)材质较硬的工件,如高硬度工具钢和硬质合金钢等.

3.for hard materials such as hard tool steels and carbide.

4)工件抗热性能差,严防表面烧伤和磨削.

4.for heat sensitive workpieces and grinding can not has

burning and discoloration on surface

●较硬的硬度

●Use Hard Grade:

1)进刀量小的精磨.

1.for fine finish with little feed

2)延长砂轮寿命.

2.for longer wheel life

3)材质较软的工件.

3.for soft materials

4)磨削接触面小或窄的场合.

4.for small or narrow areas of contact
