[Technical Case] Vanishing Processing

Experience in the high-pressure hydraulic component industry! Introduction of examples of "vanishing processing" with machining accuracy comparable to turning.

Zawakawa Forging Industry Co., Ltd. is a company engaged in the manufacturing of cold-forged bearing products, machining of hydraulic pump parts, and the production of aluminum machined products. Burnishing processing is a method that moves a tool with a smooth surface against the surface of the workpiece without generating chips, resulting in plastic deformation and work hardening on the workpiece surface, thereby achieving a smooth finish. The machining accuracy is at the level of turning, and the surface roughness is at the level of polishing (2s), which improves surface roughness and strength, resulting in a mirror-like finish. Typically, when performing polishing processing, it is necessary to change the equipment; however, with burnishing processing, the tool can be mounted on a CNC lathe, eliminating the need for setup and other labor. [Examples of Burnishing Processing Achievements] ■Outer diameter: Φ200–750 mm ■Inner diameter: Φ50–550 mm 　*If it is a ring shape, burnishing processing can be performed on both inner and outer diameters. ■Before burnishing processing Ra0.33 ⇒ After burnishing processing Ra0.05 For more details, please refer to the catalog or feel free to contact us.
