Incredible precision and rigidity born from the ball screw mechanism!
SHOWA's hard chuck is the world's first to adopt a ball screw mechanism in the chuck tightening section. As a long-selling chuck, it has established a wide variety of types and tooling systems, making it a tool that meets all machining conditions and purposes.
High-speed, high-precision, high-rigidity milling chuck
We have succeeded in creating this high-precision chuck through advanced processing technology cultivated by our unique direct clamp mechanism and years of spindle mechanism development.
A rich lineup that achieves high precision, high rotation, and high efficiency.
We use collets with ultra-precision finishing, so the runout accuracy is in microns. The collets are made from specially selected wear-resistant special steel with minimal hardening distortion, ensuring high precision and excellent durability.
