Oilstone Centerless Super-finishing Machine

Oil Stone Centerless Super-Finishing Machine (3M6280)

 Super-finishing machines use low pressure to push oilstones onto the turning workpieces, which are supported by two rollers. The workpiece and oilstone contact face by face, at the same time, the oilstone is vibrating in axial direction in high frequency. Surface roughness of workpieces can be greatly improved at very short time. The low pressure polishing can remove the previous deformation layer of workpieces without changing the surface texture. Oilstone and workpieces contact face by face, so oilstone can copy the shape automatically and then dislodge the external waviness to improve the roundness. After super-finishing, the surface quality and accuracy of the workpiece will be enhanced a lot, so it is easy to form lubricating oil film on the surface, improving the lubricating conditions and extending the working life. Compared to other processing methods, superfinishing is more efficient and labor-saved.
