磨削过程是由没有固定形状的磨粒在高速和很浅切深的条件下进行的。高速回转的磨粒、结合剂等,同工件表面之间剧烈的摩擦产生大量的热(附着在砂轮表面的切屑也与工件表面产生摩擦热)。同时,磨粒在滑擦、耕犁和切屑形成三个阶段所做的功也大都转化为热。这就是说:磨削时输入的能量大部分转化为热量,因而在磨削区形成高温,最高可达摄氏一千
Grinding process is not fixed shape of the abrasive at high speed and a very shallow depth of cut conditions. High-speed rotation of the abrasive particles, binding agents, etc., with the dramatic friction between the workpiece surface to produce a lot of heat (attached to the wheel surface of the chip and the workpiece surface friction heat). At the same time, most of the work done by abrasive grains in the three stages of sliding, plowing and chip formation is also converted into heat. This means that most of the energy input during grinding is converted to heat and thus forms a high temperature in the grinding zone up to a maximum of 1000
