数控双向推力角接触球轴承座圈沟道磨床

CNC outer groove grinders for bi-direction thrust angular contact ball bearing

主要用途Main Purposes
本系列磨床主要用于磨削双向推力角接触轴承外圈沟道，亦可用于磨削深沟球轴承、角接触球轴承（沟、斜坡一次磨）、双列球轴 承、双列角接触球轴承（双沟、双坡一次磨）、四点接触球轴承等系列轴承的外圏沟道
This series of grinders are mainly used to grind the outer groove of bi-directional thrust angular contact ball bearings, also can be used for the grinding of the outer groove of deep-groove ball bearings, angular contact ball bearings (grinding the groove and slope at the same time), double-row ball bearings, double-row angular contact ball bearing (grinding double grooves and double slopes at the same time) and four points contact ball bearings as well.
