磨料有序化排布砂轮磨削TC4温度实验研究

Experimental investigation of grinding temperature when grinding TC4 with engineered grinding wheels

为了获得磨料有序化排布砂轮磨削TC4的温度变化规律,使用电镀CBN砂轮对TC4合金进行磨削实验。砂轮分别采用叶序、错位和无序3种不同的磨料排布方式。研究了工件表面平均温度与进给速度和磨削深度的关系,并对3种磨料排布方式的电镀CBN砂轮磨削工件时温度的变化形态进行对比。结果表明:在相同磨削条件下,磨料有序化排布能有效降低TC4的磨削温度,使用叶序排布磨料砂轮能获得更低的工件表面温度。

In order to achieve the variation of grinding temperature during grinding TC4 with engineered grinding wheels . Phyllotactic , staggered and random arrangement way of electroplating CBN grinding wheels was used for grinding TC4 .Through the grinding experiment , the relationships of the feed velocity and grinding depth on the workpiece surface temperature and the comparison of grinding temperature with three kinds of engineered grinding wheels were studied . The test results revealed that the TC4 grinding temperature with engineered grinding wheels could be effectively reduced at the same grinding conditions , and lower surface temperature could be obtained with phyllotactic grinding wheel .
