Like its HMC400, OKK’s HMC500 is thoroughly built for speed and fast cycle times. Featuring a 500-mm pallet, the HMC500 is also designed to accommodate some of the largest workpieces in its class.

Performing 20% faster than OKK’s HM500S, the HMC500 achieves a rapid feed rate of 63 meters per minute (2,480 ipm) with acceleration of 1G (XYZ). It is constructed with a lightweight column, featuring a rigid stepped X axis rail design, and a high-speed built-in rotary table. A large bearing in the B axis of the rotary table, and a multi clamp pallet system, ensure rigidity.

The HMC500 boasts exceptionally fast automatic pallet and tool changers. Furthermore, a maximum tool length of 550 mm means deep boring operations can be completed without rotating the pallet, resulting in additional time savings and improved accuracy. A powerful, high torque and highly rigid 15K Big Plus Spindle allows the HMC500 to reach cutting speeds of 15,000 rpm in a mere 1.7 seconds (with 50 hp), for faster machining of a variety of tough materials, including 1018 steel. In fact, this machine is 25 percent faster at rigid tapping than OKK’s HM500S with the same cutting condition. The spindle design also improves tool accessibility. The distance from the spindle nose to the pallet center is 70mm, the shortest distance in its class.
