MAKINO MC-86 HORIZONTAL MACHINING CENTER

Technical Description

The MAKINO MC-86 is a 4-axis CNC horizontal machining center designed for high-precision and flexible manufacturing applications. It features a robust CAT 50 spindle taper and a spindle speed range typically up to 4,000 or 5,000 RPM, powered by a spindle motor of approximately 25 HP (18.6 kW). The machine's axis travels are substantial, with the X-axis providing around 31.9 inches (810 mm), Y-axis about 25 inches (635 mm), and Z-axis approximately 25 to 29.4 inches (635 to 746 mm), enabling the machining of large and complex parts. The B-axis offers full 360-degree continuous rotation with increments as fine as 0.001 degrees, facilitating multi-sided machining without repositioning the workpiece. The MC-86 is equipped with a 24.8-inch square pallet capable of supporting loads up to 3,000 lbs, optimizing workpiece handling and reducing setup times. Its automatic tool changer can hold up to 40 or more tools, supporting extended machining runs and complex tool paths. The control system is typically a Fanuc 15M or 16M CNC, offering advanced programmable features, 14-inch color CRT displays, and seamless integration for part programs and tool management. Feed rates range broadly up to about 157 inches per minute with rapid traverse speeds reaching approximately 590 inches per minute, providing efficient material removal and cycle times. The machine’s substantial floor footprint and weight (~37,000 lbs) reflect its industrial-grade construction, ensuring rigidity and stability during heavy cutting operations. Optional pallet pools (up to 12 pallets) and coolant systems with thru-spindle delivery further enhance the MC-86’s flexibility and productivity in demanding manufacturing environments.
