MITSUBISHI HEAVY IND. M-H4B HORIZONTAL MACHINING CENTER

Technical Description

The Mitsubishi Heavy Ind. M-H4B Horizontal Machining Center is a 3-axis CNC machine optimized for precision horizontal milling and drilling tasks. It features a 15.7" x 15.7" standard support index table capable of supporting workpieces up to 880 lbs. The machine offers travel along the X, Y, and Z axes of 25.6", 22.0", and 25.6" respectively, with rapid traverse speeds up to 1,575 inches per minute, ensuring efficient material removal and cycle times. The horizontal spindle utilizes a CAT #40 taper with a top speed of 12,000 RPM, powered by a robust 30 HP motor (30-minute rating), with an optional upgrade to 20,000 RPM. Tool handling is managed by an automatic tool changer (ATC) carrying 40 tools as standard, extendable to 120 tools for enhanced flexibility, with an average tool change time of 1.3 seconds and chip-to-chip time of 3.8 seconds. The machine includes a standard pallet changer system supporting two pallets, each measuring 15.7" x 15.7", with 1-degree pallet indexing for precise fixture positioning. The spindle supports coolant through spindle for effective thermal control, while the control system is typically equipped with a Fanuc 18i-M CNC controller, facilitating advanced machining operations. The machine weighs approximately 23,000 lbs and includes features such as chip conveyors and flood coolant systems to optimize operational efficiency and maintenance. This machining center is ideal for high-precision and medium-to-large volume production environments requiring reliable horizontal milling capabilities.
