HMC Designed for Speed and Large Workpiece Machining
October 1, 2014
OKK's new HMC500 horizontal machining center (HMC) is built for speed and faster 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 and features 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 help ensure rigidity.
"The HMC500 features fast automatic pallet and tool changers," said a company spokesperson. "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 rigid 15K Big Plus spindle allows the HMC500 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. In fact, 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 70 mm, the shortest distance in its class."
The 1,000 PSI coolant through spindle unit features a 5 micron bag filter which can be easily replaced without interrupting the cycle. "More than three times longer life can be achieved compared to conventional line filter systems," said the spokesperson. "Additionally, virtually all maintenance controls and gauges are centrally located on the front of the machine for convenient daily inspection."
