OKK HM600 HORIZONTAL MACHINING CENTER

Technical Description

The OKK HM600 Horizontal Machining Center is a high-performance 4-axis CNC machine engineered for complex and precision horizontal machining tasks. It features a 24.8" x 24.8" pallet size capable of supporting workpieces up to approximately 1540 lbs. The machine offers substantial travel distances of 30.71" along the X-axis, 29.53" along the Y-axis, and 31.5" along the Z-axis, enabling versatile machining across multiple dimensions. Powered by a robust 40 hp spindle motor, the HM600 attains speeds up to 12,000 RPM with a CAT #50 tool taper, providing both rigidity and high-speed capability essential for heavy cutting and fine finishing. Its automatic tool changer holds up to 60 tools, facilitating extended unattended operation and efficient tool management. Rapid traverse rates reach up to approximately 2,600 inches per minute on all axes, enhancing productivity. The machine incorporates advanced features such as coolant through the spindle and chip conveyor systems for effective cooling and chip evacuation. Equipped with a 4th-axis B-axis pallet indexing with 0.001° precision, it supports complex angular machining processes. The HM600’s construction ensures rigidity and reliability, with oil-air lubrication for spindle bearings and hydraulic clamping for stable workholding. Overall dimensions are roughly 168" x 120" x 123", with a weight of approximately 31,500 lbs, reflecting its industrial-grade build quality suitable for demanding manufacturing environments. This machine is ideal for industries requiring precision machining of large and complex parts with high productivity and accuracy.
