摘要
根据半人工热电偶测温原理制备了磨削测温试样,利用感应钎焊金刚石砂轮和电镀金刚石砂轮进行硬质合金YG6的磨削试验,研究了磨削深度、工件进给速度对工件表面磨削温度的影响。试验结果表明:在相同的磨削参数下感应钎焊金刚石砂轮的磨削温度要远低于电镀金刚石砂轮,且随着磨削深度和工件进给速度的增大磨削温度上升较为平缓,钎焊金刚石砂轮磨粒出露高度高、容屑空间大,磨粒呈有序排布是磨削温度较低的主要原因。
Samples for artificial thermocouple. measurement of grinding temperature were prepared according to the principle of semi - Grinding experiments were carried out on cemented carbide YG6 with induction brazed diamond grinding wheels and electroplated diamond grinding wheels, the influence of grinding depth and feed rate on grinding temperature were investigated. Experimental results revealed that the grinding temperature when using brazed diamond grinding wheels was far lower than that when using electroplated diamond grinding wheels under the same grinding parameters. Moreover, the grinding temperature of brazed diamond grinding wheels tends, to rise more gently along with the increase of grinding depth and feed rate. Lower grinding temperature of the brazed diamond grinding wheels is attributed to high exposing height, large storage space for chips and orderly arrangement of brazed diamond grits.
