New concepts in high-speed machining offer drastic improvements in speed, rigidity and durability over competing machines. The OKK HM1250S offers heavy duty cutting performance by incorporating a rigid frame of think box-shaped structure to foundation the large linear roller guides designed for very heavy loads.
The fastest and most powerful machines in their class, our HM series offers easy access, maintenance, and operation. High-speed rotation APC and ATC by synchronization cam (patented by OKK) delivers smooth performance and production efficiency.
