Fine Blanking
Fine Blanking
Superconducting magnets
Fine blanking is a metal processing technology that combines elaborateness and precision.
It is possible to provide smooth sheared surfaces and micron levels of accuracy by pressurizing and holding the work material with three hydaulic operations called triple action and punching the die parts with a minimum clearance.
We have worked with many difficult to process metals including special steels, stainless steels, and super alloys, as well as products with complex shapes.

Proficiency
In fine blanking, products are pressed and finished with micron accuracy. Since the sheared surface is extremely smooth, and other types of processing such as crushing and piercing holes can be done simultaneously, it is possible not only to shorten the finishing process but also efficiently manufacture parts with complex shapes.
AFB Feature
Our outstanding feature is continuous processing of difficult to process materials.
We mass-produce precision parts mainly made of stainless steel.

By obtaining a fine sheared surface, it is possible to press products with punched side surfaces as functional surfaces and to abolish the finishing process.
Also, it is expected that the process will be reduced and the material yield will be improved by changing the construction method from casting and forging materials.
