MAKINO A92 HORIZONTAL MACHINING CENTER

Technical Description

The Makino A92 Horizontal Machining Center is a high-performance 4-axis CNC machine designed for large and heavy workpieces, particularly in industries such as diesel engine block and construction equipment manufacturing. It features a robust horizontal spindle with a CAT50 taper, optionally HSK-A100, capable of speeds up to 10,000 RPM and powered by a 47 HP motor (30-minute rating). The machine supports a maximum workpiece weight of 2,640 lbs on a 31.5" x 39.4" table, with travels of 59.8" (X), 49.2" (Y), and 53.1" (Z), all capable of rapid traverse rates of 1,969 ipm. The B-axis rotary table offers 360° indexing for complex 4-axis machining. Tool handling is highly efficient with an Automatic Tool Changer (ATC) accommodating up to 316 tools, providing a rapid 1.9-second tool-to-tool change and a 5.4-second chip-to-chip change. A dual-pallet changer system is standard, enhancing uptime and productivity. Optional rotary tables and high-pressure (1,000 PSI) thru-spindle coolant systems further optimize machining versatility and cooling. The machine’s structural design ensures exceptional stiffness and rigidity, enabling high-thrust, high-accuracy machining throughout the large work envelope. Control is managed via Makino’s Pro5 CNC system, which supports advanced features like probing and broken tool detection to maintain precision and reduce downtime. Overall, the A92 excels in heavy-duty, high-volume machining applications requiring large work zones, fast cycle times, and reliable multi-tool handling.
