1.Introduction of Super Refine Grinding

(1)What is Super Refine Grinding?

Super Refind Grinding is a finishing method,which is under good lubricating and cooling conditions,use a fine-grained abrasive(oil stone)to exert a small pressure on the workpiece,perpendicular to the direction of rotation of the workpiece,and perform a fast and short reciprocating oscillatory motion on the workpiece which is rotating at a certain speed.

(2)The role of Super Refine Grinding

In the manufacturing process of rolling bearings,superfinishing is the last process of bearing ring processing.It can reduce or eliminate the circular deviation left by grinding,correct the shape error of the groove;refine its surface roughness,improve the surface physical and mechanical performance.It plays an important role in effectively reducing the waviness of the groove,reducing the vibration and noise of the bearing,improving the lifecycle of the bearing.

2.LZK Super Refining Machine

Recently,LZK newly purchased four sets of Super Refining Machine for the final processing of large and extra-large precision bearings.The processing size range coversφ200-φ1800,which can be used for the processing of bearing grooves,rollers,ribs,etc.Among bearing enterprises of the same scale and type,the configuration of LZK’s equipment reaches to the top level.
