Makino V56I-5XB GRAPHITE VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a 7.87" x 7.87" square table with a maximum workpiece capacity of 66 lbs, optimized for precision machining without additional support indexing for the table or rotary table. It operates on a vertical spindle configuration with a CAT 40 taper and an optional upgrade to HSK-A63 taper for improved rigidity and accuracy at high speeds. The spindle delivers 20,000 RPM standard with a 30,000 RPM option, powered by a 20 HP motor rated for 30-minute operation, upgradable to 23 HP. Tool handling is managed by an Automatic Tool Changer (ATC) with a 25-tool capacity, expandable to 60 tools, and a rapid 6.5-second tool change time. An optional pallet changer is available to enhance workflow efficiency. The machine incorporates five axes—X, Y, Z linear axes with travels of 35.4", 18.1", and 17.7" respectively, each with maximum feed and rapid traverse rates of 787 inches per minute, and a B-axis rotary capability of 130 degrees. The absence of a U-axis simplifies the configuration. These specifications indicate suitability for complex 5-axis machining projects requiring high precision, dynamic feed rates, and rapid tool change cycles. The CAT 40 taper spindle enables robust torque transmission, while the HSK-A63 option provides improved spindle-tool interface precision and stability at high RPMs, reducing vibration and enhancing surface finish quality. This machine is engineered for high-speed, multi-tool machining of medium-sized parts with complex geometries, ideal for aerospace, automotive, and precision industry applications. The combination of high spindle power, rapid tool indexing, and five-axis control delivers versatility and productivity for demanding CNC milling tasks.
