Makino A55 HORIZONTAL MACHINING CENTER

Technical Description

The 1993 Makino A55 Horizontal Machining Center is a high-performance CNC machine designed for precision milling and drilling with a robust build weighing approximately 20,000 lbs. It features equal axis travels of 22.05 inches on the X, Y, and Z axes, enabling versatile machining of complex parts. The machine is equipped with a 15.75" x 15.75" pallet size and supports two pallets with a maximum table load capacity of 880 lbs, facilitating efficient workpiece handling and productivity. Its spindle runs at speeds up to 12,000 RPM with a #40 taper, powered by a 30 HP motor that delivers substantial machining power. An automatic tool changer (ATC) with 40 tool stations supports rapid tool switching, enhancing cycle times and operational efficiency. The control system is a Fanuc OM CNC, known for precise motion control and user-friendly programming. Additional features include coolant through spindle for effective cooling during cutting, rigid tapping for threading operations, a chip conveyor for automated chip removal, and onboard coolant tank capacity to maintain cutting fluid. These specifications combine to make the Makino A55 suitable for aerospace, automotive, and general manufacturing applications where high accuracy and repeatability are critical. The machine’s compact pallet size, simultaneous two-pallet setup, and durable construction enable continuous, reliable operation in demanding production environments. This model balances high spindle speeds with torque, precise axis travels, and automated tool handling, catering to complex, high-volume manufacturing needs. The included components such as chip conveyor and thorough coolant system improve process stability and tool life, while the Fanuc OM control system provides versatility and integration for advanced CNC machining workflows.
