JKM8318数控凸轮轴靠模磨床导轨设计
凸轮轴靠模磨床是一种高速凸轮轴磨床，其工作原理是利用靠模，与普通机床相比工作稳定性好，操作维护简单，自动化程度较高，这种凸轮轴磨床在国内得到普遍应用。JKM8318数控高速凸轮轴磨床是根据目前市场需要，在原简易数控、三座标凸轮轴磨床基础上改进开发出来的高速、高效数控凸轮轴磨床。采用CBN砂轮磨削，砂轮线速80-120米/秒，有机地将靠模与数控，双循环磨削和CBN砂轮强力磨削两种先进的磨削方式综合，加工效率远远高于普通凸轮磨床，1-2倍工作，稳定性好，操作维护简单，自动化程度较高，在国内具有领先地位，本机床主要适用于汽车、摩托车、内燃机的凸轮轴粗加工和半精磨加工。数控凸轮轴靠模磨床导轨是在油腔通入一定压强油，使导轨面形成有一定厚度的油膜来支撑的原
理来工作的。

JKM8318 CNC camshaft by mold grinder rail design
Abstract
Camshaft by jig grinders is a high-speed camshaft grinding machine, its working principle is the use by mold, compared with the ordinary machine, good working stability, simple operation and maintenance, higher degree of automation, this camshaft grinding machines in the country are universally applied. CNC high speed camshaft grinder in JKM8318 is based on the current market needs, developed on the basis of the original simple numerical control, coordinate camshaft grinder to improve high-speed, efficient CNC camshaft grinder. The CBN grinding wheel, wheel wire speed 80-120 m / s, organically by mold and CNC grinding two-loop grinding and CBN grinding wheel, powerful grinding two integrated processing efficiency is much higher than ordinary cam grinder 1-2 times the work, good stability, simple operation and maintenance, high degree of automation, and has a leading position in the country, this machine is mainly used in automobiles, motorcycles, internal combustion engine camshaft roughing and semi-fine grinding. CNC camshaft rely on jig grinders rail pass into certain pressure oil in the oil chamber, the rail surface to the formation of a certain thickness of the film to support the principle of work.
