GENOS M4000H-e Horizontal Machining Center Holds 64 Tools

Holding dimensional accuracy through heavy-duty cutting, high-speed machining, and long continuous production runs depends on a rigid machine bed and control over thermal growth. The GENOS M4000H-e is an entry-level 4-axis horizontal machining center with a cast-iron bed, a 64-tool automatic tool changer, and a two-station pallet changer, built for fast, precise machining in a compact footprint. It is based on the MB-H series and is supplied as a complete, ready-to-use machine.

The cast-iron bed dampens vibration during heavy-duty and high-speed machining, while the Thermo-Friendly Concept compensates for temperature fluctuations to maintain dimensional stability during continuous long-term operation.

The 16 x 16 in (400 x 400 mm) table and X, Y, and Z-axis travels of 22, 22 in, and 25 in (560, 560, and 625 mm) accommodate workpieces up to 24 in (600 mm) in diameter and 35 in (900 mm) in height. The B-axis allows 4-sided machining in a single setup. With a maximum rapid traverse of 2,362 in/min (60 m/min) and a 15,000 rpm spindle delivering 147 lb-ft (199 Nm) of torque, the machine can process all types of materials.

The automatic tool changer holds 64 tools in a chain magazine and is designed for easy access, with tool-to-tool change times of 1.0 s and chip-to-chip times of 2.6 s. The two-station pallet changer further reduces downtime. A chip management system provides high-volume flushing of chip deposits and through-spindle coolant supply. The OSP control streamlines control operations and reduces setup times.
