561 Published by admin Sep 05,2018

1.ZYSL Co., Ltd is a angular contact bearing manufacturer. A double-half inner ring three-point angular contact ball bearing processing method, characterized in that the method is implemented as follows:

angular contact bearing manufacturer

First, ZYSL Co., Ltd is a angular contact bearing manufacturer,the vertical axis CNC double-face grinding machine is used to finish the two end faces of the semi-inner ring of the bearing through the upper grinding head and the lower grinding head, and the bending degree of the end face of the semi-inner ring of the bearing is controlled to be less than 2 μm, and the same batch of bearings is controlled. The mutual difference of the end face dimensions (B) of the ring is less than 8 μm;

Second. ZYSL Co., Ltd is a angular contact bearing manufacturer.The outer circumference surface of the semi-inner ring of the bearing is ground by a numerically controlled cylindrical grinding machine, and the outer diameter (d2) of the semi-inner ring of the same batch bearing is controlled to be less than 12 μm;

Third. ZYSL Co., Ltd is a angular contact bearing manufacturer.According to the required inner diameter dimensional tolerance range, the inner diameter (d) of the semi-inner ring of the bearing is ground by a numerically controlled internal grinding machine. After the fine grinding, the inner diameter dimension deviation is measured, and the inner diameter dimension deviation is marked on the end surface of the bearing inner semicircle;

Fouth. ZYSL Co., Ltd is a angular contact bearing manufacturer.According to the difference of the end face size (B) of the semi-inner ring of the bearing is less than 3μm, the groove of the semi-inner ring of the bearing is ground by the numerical control internal grinding machine;

high quality angular contact bearing manufacturer

Fifth. ZYSL Co., Ltd is a angular contact bearing manufacturer.Using the CNC channel lapping machine, input the groove curvature center diameter (dR), channel curvature radius (R), eccentricity (e), and the end face size of the workpiece semi-inner ring (B) at the input interface of the lapping machine. , that is, the center position of the groove curvature is determined, and the calculated angle of the oil stone is cut into the angle (α), and the oil stone clamp is manually adjusted to the required cutting angle (α) according to the equipment oil stone clamp angle scale, that is, the oil stone swing is determined. At the center position, when the channel is finished, the groove diameters (de) at the pressure points of the semi-inner ring of the bearing are different from each other by less than 3 μm. After the machining is completed, the plastic inner belts of each pair of bearings are attached to the inner ring. Together, the processing of the double-half inner ring three-point angular contact ball bearing is completed by ZYSL angular contact bearing manufacturer.
