Detailed Product Description

Oilstone Super finishing Machine

Superfinishing machining is using lower pressure to push oilstones and lay on the turning workpieces for creating a

face-contact state; meanwhile, the oilstone is vibrating in axial direction at high frequency. The main features are as

follows:

Extremely improved the oughness of workpiece (commonly, Ra 0.025μm is available).

The abnormal changes will not occur on the surface structure of workpiece and most of or all of surface

metamorphic layer created during fore-process (grinding or cutting ) can be taken away thanks to machining under

lower pressure.

Because of oilstones and workpiece touching on surface and copying automatically, so it can dislodge the surface

corrugation grining appeared, and the roundness can be upgraded.

After superfinishing,the accuracy of workpiece is improved; Forming librication oil pellide easy and librication

qualification long service life and high loading capacity are available. Therefore, it is the laboursaving and high

efficiency machining method compared with others.
