DAINICHI MX75 CNC LATHES

Technical Description

The Dainichi MX75 is a heavy-duty horizontal CNC turning machine engineered for precision metalworking across automotive, aerospace, and manufacturing sectors. This machine features a robust main spindle with a maximum swing of 29.53 inches and accommodates workpieces up to 18.11 inches in diameter with turning lengths reaching 157.48 inches, utilizing an 18-inch chuck for secure workholding. The spindle delivers 1,400 RPM with selectable motor configurations of 50 or 60 horsepower, ensuring adequate power for demanding cutting operations. The machine operates on four axes with dual turret tool carriers—each capable of holding eight turning and eight rotary tools—enabling simultaneous dual-tool cutting for enhanced productivity. Axis travel specifications include 19 inches on the X-axis, configurable Z-axis travel of either 40 or 160 inches, and rapid traverse rates of 236 inches per minute across all axes. The machine integrates Fanuc CNC controls with servo motors driving the X and Z axes, facilitating precise positioning and repeatability. With its substantial 12,100-pound weight and Fanuc 15T control system, the MX75 delivers exceptional rigidity and surface finish quality. The inclusion of steady rests, boring bar attachments, and chip conveyor systems complements its versatile tooling capabilities, making it suitable for complex turned components including shafts, gears, and precision axles requiring intricate geometries and tight tolerances.
