Okuma MA500HB HORIZONTAL MACHINING CENTER

Technical Description

The Okuma MA-500HB is a robust horizontal machining center designed for versatile production and job shop applications. This machine features a generous work envelope with X, Y, and Z axis travels of 27.5", 35.43", and 30.71" respectively, accommodating workpieces up to 800mm in diameter and 1,000mm in length. Powered by a 30 horsepower spindle motor, the machine delivers consistent performance at a maximum spindle speed of 6,000 RPM, making it suitable for heavy-duty cutting operations and extended production runs. The automatic tool changer (ATC) holds 60 tools, enabling uninterrupted machining cycles and reduced downtime during tool changes. The system utilizes CAT 50 spindle taper compatibility, ensuring access to a wide range of cutting tools. Equipped with dual 19.69" × 19.69" pallets with a weight capacity of 1,760 lbs each, the machine accommodates multiple workpiece setups and enables rapid part changes without stopping the spindle. The pallet height adjustment ranges from 1.97" to 37.40" from the spindle center, providing flexibility for complex part geometries. Control is managed through an Okuma CNC system, typically featuring either OSP-P200M or OSP-E100M controls depending on the specific machine vintage. The machine itself measures 121.26" × 223.22" × 120" in overall dimensions and weighs approximately 52,000 lbs, requiring solid foundation preparation. Integrated chip conveyor and optional tool presetting capabilities enhance operational efficiency. This proven platform remains popular in small to mid-sized production facilities worldwide.
