| 磨料粒度: | Grit | | | | | |
| 精度是用来表示磨料颗粒几何尺寸的大小,其选择 | Grit is designated to represent the geometrical size of |
| 依据主要是加工工件所需要的表面粗糙度,同时也需 | abrasive grain.The grit size is chosen for customer's |
| 考虑其他一些因素.以外圆磨为例,常用粒度与表面 | required surface finish as well as other conditions.For |
| 糙度有下面的大致关系: | example,in cylindricai grinding,there is relationship |
| | | | | | | between grit and surface finishes listed as bellow; |
| 粒度 | 36-46 | 54-60 | 70-80 | 90-100 | | | Grit | 36-46 | 54-60 | 70-80 | 90-100 | |

| <粗料度的磨料适用于磨削: | | | | |
| 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 |
| 材料 | | | | | | | 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: | | | | |
| 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. | | | | 3.for small areas of contact | | | |
| 4)工件半径或弧度小的场合. | | | | 4.for holding small corner radii | | |

| 砂轮的硬度是指磨料之间的结合度,砂轮中结合 | The grade indicates the relative holding power of the |
| 剂量的多少决定了砂轮的硬度大小.用户需根据具 | bond which holds abrasive grains in a wheel.ln general, |
| 本的磨削(如进刀量,粗糙度,材质)要求来灵活选 | with a given type of bond it is the mount of bond which |
| 择砂轮的硬度. | | | | | | determines a wheel's should select the grade of a wheel |
| 一般砂轮硬度选择的原则是: | | | | based on the grinding parameters such as feed rate. |
| | | | | | | finish requirements,materiials i.e..The following rules |
| | | | | | | should be followed with regard to grade | | |
| <较软的硬度 | |
| 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 | |
| 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 | |
