内燃机活塞顶油腔曲型面,过去,一直是在普通车床上靠手工操作纵横刀架‘赶刀’加工的。这样加工比较麻烦,工作中需更换五种不同刀具,并且工人劳动强度大,生产效率低。由于加工面形状的限制,刀具刚性差,不仅产生刺耳的噪音:而且经常打刀,成了生产关键。 Internal combustion engine piston top oil curved surface, in the past, has been in the ordinary lathe by vertical and horizontal tool holder ’rush knife’ processing. This process is more troublesome, work needs to be replaced five different tools, and workers labor-intensive, low productivity. Due to the shape of the machining surface, tool rigidity is poor, not only produces harsh noise: and often hit the knife, has become the key production.
