style="text-indent:25px">車刀刃磨砂輪的選擇（2)粒度：粒度表示磨粒大小的程度。以磨粒能通過每英寸長度上多少個孔眼的數(shù)字作為表示符號。例如60粒度是指磨粒剛可通過每英寸長度上有60個孔眼的篩網(wǎng)。因此，數(shù)字越大則表示磨粒越細。粗磨車刀應(yīng)選磨粒號數(shù)小的砂輪，徐州機夾車刀訂制，精磨車刀應(yīng)選號數(shù)大(即磨粒細)的砂輪。船上常用的粒度為46號—臺0號的中軟或中硬的砂輪。（3)硬度：砂輪的硬度是反映磨粒在磨削力作用下，從砂輪表面上脫落的難易程度。砂輪硬，即表面磨粒難以脫落；砂輪軟，表示磨粒容易脫落。砂輪的軟硬和磨粒的軟硬是兩個不同的概念，必須區(qū)分清楚。刃磨高速鋼車刀和硬質(zhì)合金車刀時應(yīng)選軟或中軟的砂輪。另外，在選擇砂輪時還應(yīng)考慮砂輪的結(jié)合劑和組織。船上和工廠一般選用陶瓷結(jié)合劑(代號A)和中等組織的砂輪。綜上所述，我們應(yīng)根據(jù)刀具材料正確選用砂輪，徐州機夾車刀訂制。刃磨高速鋼車刀時，徐州機夾車刀訂制，應(yīng)選用粒度為46號到60號的軟或中軟的氧化鋁砂輪。刃磨硬質(zhì)合金車刀時，應(yīng)選用粒度為60號到80號的軟或中軟的碳化硅砂輪，兩者不能搞錯。硬質(zhì)合金車刀刀尖圓弧半徑rε和副偏角κr'一般按加工表面粗糙度的要求而選取。徐州機夾車刀訂制</p><div
