对硬质合金YG6、YT30的精密磨削进行了磨削力的实验研究．测定和分析了实际摩削深度、工作台速度与单位磨削力的对应关系；比磨削能与工作台速度、实际磨削深度的对应关系，以及比磨削能力与去除量之间的对应关系，并将YG6和YT30分别进行了比较。实验证明，单位磨削力随工作台速度和实际磨削深度的增加而增加。比磨削能随工作台速度和实际磨削深度，以及材料去除率的增加而降低。在同样磨削参数条件下，YG6的单位磨削力和比磨削能要大于YT30．
The grinding force of the precision grinding of cemented carbide YG6, YT30 was studied. The relationship between the actual grinding depth, the table speed and the unit grinding force was measured and analyzed. The corresponding relationship between the specific grinding energy and the table speed and the actual grinding depth, and the correlation between the specific grinding capacity and the removal amount Relationship, and YG6 and YT30 were compared. Experiments show that unit grinding force increases with table speed and actual grinding depth. Specific grinding can be reduced with stage speed and actual grinding depth, as well as material removal rates. Grinding parameters in the same conditions, YG6 unit grinding force and grinding capacity to be greater than YT30.
