Makino A51 NX HORIZONTAL MACHINING CENTER

Technical Description

The 2014 Makino A51 NX Horizontal Machining Center is a high-performance, 40-taper production machine engineered for precision, speed, and reliability in demanding manufacturing environments. Equipped with the advanced Pro 5 Control system, this HMC delivers seamless operation, robust programming capabilities, and intuitive user interface for efficient part production. The machine features a 60-tool Automatic Tool Changer (ATC), supporting rapid tool changes with a tool-to-tool time of just 0.9 seconds and chip-to-chip time of 2.2 seconds, minimizing non-cutting time and maximizing throughput. The CAT 40 spindle delivers a maximum speed of 14,000 RPM, providing high torque and power for both ferrous and non-ferrous material applications, while the rapid traverse rate reaches 2,362 ipm and cutting feedrate up to 1,968 ipm for aggressive machining strategies. The work envelope offers X, Y, and Z travels of 22", 25.2", and 25.2" respectively, with a maximum workpiece capacity of ø24.8" x 35.4" and a pallet size of 15.7" x 15.7" supporting up to 880 lbs. The machine is further enhanced with two Tsudakoma RWB-250K 5th axis rotary tables, enabling complex multi-sided and 5-axis machining operations with high indexing accuracy. Additional features include high-pressure coolant through the spindle, chip conveyor, and robust construction for long-term reliability. The Makino A51 NX is ideal for high-volume production, automotive, aerospace, and precision machining applications requiring consistent accuracy and productivity.
