HIGH PRECISION DIE SET
Yamanaka Eng provide well-designed die set for the conventional press that achives high-precision forging.
Troubles that can be solved by "High Precision Die Set"solution
Drastic Improvement of Tool Life
Improvement of Product Accuracy
Development of New Products having Functions for the Future
Reduces the influence of press slide tilting due to the lateral and rotary motion of the press. Only the axial component is transmitted to the punch.
The accuracy is achieved by fitting the punch holder with the die holder. (Centering, vertical alignment)
In addition, the clearance between the punch and the punch holder is accurately controlled to reduce punch deflection and tilt, ensuring straightness of the punch.
High precision forging mechanism is applied to backward extrusion forging of cup products by mechanical press.
Compared with products using a general die set, the variation in accuracy has been greatly reduced, and concentricity of 9 μm or less has been achieved.
- Mechanical Press
