[Technical Case] Vanishing Processing

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

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 technique that moves a tool with a smooth surface against the surface of the workpiece without generating chips, causing plastic deformation and work hardening on the workpiece surface to achieve a smooth finish. The machining accuracy is at turning level, and the surface roughness is at polishing level (2s), resulting in improved surface roughness and strength, with a finish that resembles a mirror. Typically, when performing polishing processing, it is necessary to change the equipment, but 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 to 750 mm ■ Inner diameter: Φ50 to 550 mm * If in a ring shape, both inner and outer diameter burnishing processing is possible ■ Before burnishing processing Ra0.33 ⇒ After burnishing processing Ra0.05 For more details, please refer to the catalog or feel free to contact us.
