本机床为磨削普通级精度的单列向心球轴承内圈沟道的专用磨床,可列入轴承生产自动线,或作全自动单机使用.本机床采用切入式磨削原理,进给系统采用控制力进给,砂轮与工件在磨削中保持恒定压力.电气控制采用可控硅的无触点通断开关系统,砂轮自动修整,修整后自动补偿.测量系统为“定程测量”,简单可靠.整体结构简单,操作安全方便,生产率高,以试磨317轴承内圈为例:单件工时20秒,加工光洁度(?)8,椭圆度1～2微米.比同类仿苏老产品M8814K生产率提高近一倍.
This machine is a special grinder for grinding the inner ring groove of the single row radial ball bearing with ordinary precision, which can be included in the automatic production of bearings or used in the fully automatic stand-alone machine. The machine adopts the principle of plunge-cutting grinding and the feeding system adopts the control Force feed, grinding wheel and workpiece to maintain a constant pressure in the grinding Electrical control SCR non-contact on-off switch system, grinding wheel automatically trimming, automatic compensation after trimming Measuring system for the “measuring” simple and reliable . The overall structure is simple, safe and convenient operation, high productivity, to try grinding 317 bearing inner ring, for example: single piece working hours 20 seconds, processing finish (?) 8, ovality 1 ~ 2 microns. Nearly doubled.
