MAZAK M4 CNC LATHE

Technical Description

This is a precision CNC turning center equipped with a FANUC 6T control system, designed for high-accuracy production work. The machine features a 12-inch chuck capacity with a maximum cutting diameter of 20.9 inches and a spindle nose configuration of A28. The bed structure accommodates a swing over bedways of 22 inches and a swing over cross slide of 11 inches, while the 60-inch distance between centers enables machining of extended workpieces. The X-axis travel of 21.7 inches and Z-axis travel of 60.2 inches provide substantial working envelope for complex part geometries. The main spindle bore measures 3.1 inches with a robust 25 HP motor drive, delivering the power necessary for demanding turning operations. The FANUC 6T control represents a closed-loop CNC system incorporating high-speed microprocessors and custom LSIs for reliable operation and precise velocity control. This controller features a self-diagnostic function and MDI capability with CRT display, enabling efficient program input and parameter monitoring. The system employs FANUC OC servo motors with high-performance pulse encoders for feedback detection, ensuring tight positional accuracy and repeatability. Communications capabilities include RS-232 connectivity for program transfer from external computers. The 6T control's architecture supports programmable controller functions with ROM-based power sequence management, making it well-suited for multi-tool turret operations and complex cutting cycles common in modern job shop and production environments.
