近来,由于硬质合金刀片价格的迅速上涨,刀片的重磨工艺又提到日程上来了,在许多情况下,已经有人将用钝的不重磨刀片重磨成小一号的刀片。本文将讨论砂轮磨粒的大小和冷却剂对硬质合金刀片崩刃的影响。试验设备为一台带有横向进给装置的手动砂轮机,它可手动进给、固定进给或压力进给。试验时,由一个调整螺钉将刀片固定在使其约有0.8～1.6毫米外伸量的位置上。用浸泡 Recently, due to the rapid price increase of carbide inserts, the regrinding process of the blades has also been mentioned on the agenda. In many cases, some people have already been resharpened into smaller ones with blunt, non-regrind blades. This article will discuss the size of the abrasive grains and the effect of coolant on the chipping of cemented carbide inserts. The test equipment is a hand-held grinder with infeed, which can be fed manually, fixed or fed. During the test, an adjusting screw is used to hold the blade at an extension of about 0.8 to 1.6 mm.
