OKK HM-50S HORIZONTAL MACHINING CENTER

Technical Description

The OKK HM-50S is a 4-axis horizontal machining center featuring an X-axis travel of 24.4", Y and Z-axis travels of 22.05" each, and a powerful 30 HP spindle motor capable of reaching up to 10,000 RPM. It utilizes a CAT 40 spindle taper and includes a high-speed automatic tool changer (ATC) with a capacity of 60 tools, facilitating efficient tool management and rapid tool change times around 1.3 seconds. The machine is equipped with twin pallet changers, each with a pallet size of 19.7" x 19.7", supporting quick pallet indexing and change times typically around 5 seconds. It supports a maximum table load capacity nearing 882 lbs and includes features such as through-spindle coolant delivery at 1000 PSI for optimized cutting performance and chip evacuation. The machine structure measures approximately 156" x 120" x 115" high and weighs about 30,700 lbs, reflecting a robust build for heavy-duty machining. Additional capabilities include rapid traverse rates up to 1,575 inches per minute on all axes, precise feed control with digital servo motors, and protective splash guards with full enclosure to ensure operational safety. The HM-50S incorporates advanced features like synchronous tapping, helical interpolation, and soft scale feedback on the Y and Z axes for enhanced precision. Control is typically via a Fanuc or Mitsubishi CNC system, supporting extensive memory and programmable functions ideal for complex, high-precision production environments.
