New concepts in high-speed machining offer drastic improvements in speed, rigidity and durability over competing machines. Our HM series offers the fastest and most powerful machines in their class, while providing easy access, maintenance and operation. Heavy duty cutting performance is delivered by incorporating a rigid frame of think box-shaped structure to foundation the large linear roller guides designed for very heavy loads. High-speed rotation APC and ATC by synchronization cam (OKK patent) delivers smooth performance and production efficiency.
