OKK HMC400 HORIZONTAL MACHINING CENTER

Technical Description

The OKK HMC400 Horizontal Machining Center is a high-performance CNC machine designed for precision and high-speed machining of complex workpieces. It features a 15.75" x 15.75" square pallet table capable of supporting up to 882 lbs, with a standard rotary table for enhanced flexibility. The machine operates on three axes (X, Y, Z) with travels of 22.05", 22.05", and 27.17" respectively, and offers rapid traverse rates up to 2,480 inches per minute, enabling fast and efficient machining cycles. The HMC400 is equipped with a horizontal CAT40 spindle rated at 50 HP (30-minute rating) that can reach speeds up to 15,000 RPM with high torque, allowing machining of a wide range of materials, including tough steels. Its 40-position automatic tool changer (expandable to 60) facilitates quick tool changes with an average change time of 2.8 seconds, further enhanced by a standard two-pallet automatic changer system to support continuous operation and reduced downtime. This machine integrates advanced features such as 1G acceleration for rapid feed movement, a high-rigidity multi-clamp pallet system, and a compact spindle-to-pallet center distance to optimize tool accessibility and reduce cycle times. The HMC400 is controlled by Fanuc 31i-B CNC control, enabling full B-axis contouring and precise pallet indexing at 0.001 degrees. With its robust construction and precision components, the OKK HMC400 is ideal for high-volume automotive, aerospace, and general industry manufacturing applications requiring speed, accuracy, and versatility.
