我厂自行设计的 3M 1322型与 3M1428型切入式球轴承滚道磨床,可以用来磨削球轴承和“四点接蚀式”球轴承*的滚道。该机床是用成型砂轮切入法进行加工的,可加工“S”级的球轴承滚道。加工“四点接触式”球轴承的滚道时,砂轮修整器应将成型砂轮的母线修整为“对称的甲圆弧曲线”, I designed the factory 3M 1322 and 3M1428-type in-line ball bearing roller grinder can be used to grind ball bearings and “four-point contact with the” ball bearings * raceway. The machine is formed with the cut into the law for processing, Machinable “S” ball bearing raceway. Processing “four-point contact” ball bearing raceway, the wheel dresser should be shaped grinding wheel bus trimmed to “symmetrical a circular arc curve”
