HMC Offers High-Speed Features
September 1, 2014
OKK's HMC400 horizontal machining center (HMC) is engineered for speed and faster cycle times, performing 20% faster than the company's HM500S. With the inclusion of a lightweight column featuring a rigid stepped X-axis rail design, the HMC400 achieves a rapid feedrate of 63 meters per minute (2,480 IPM) with acceleration of 1 G (XYZ).
According to the company, the HMC400's built-in rotary table operates with increased speed. A large bearing in the B-axis of the rotary table and a multi-clamp pallet system help ensure rigidity. Further contributing to the HMC400's high-speed performance are a fast automatic pallet changer and a quick automatic tool changer. The HMC400 accepts a wide variety of tool sizes, including tools up to 450 mm long. A longer tool allowance means deep boring operations can be completed without rotating the pallet, providing additional time savings. A high torque and rigid 15K BIG Plus spindle allows the HMC400 to reach cutting speeds of 15,000 RPM in 1.7 seconds (with 50 HP) for faster machining of a variety of tough materials, including 1018 steel. This machine is 25% 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 50 mm, the shortest distance in its class, according to the company.
Maintenance was also considered in the time-saving design of the HMC400. The 1,000 PSI coolant through spindle unit features a 5 micron bag filter that can be easily replaced without interrupting the cycle. According to the company, more than three times longer life can be achieved compared to conventional line filter systems. Almost all maintenance controls and gauges are centrally located on the front of the machine for convenient daily inspection. The HMC400 includes a low profile chip conveyor that requires less space behind the machine.
