VICTOR 45320DCL CNC LATHE

Technical Description

The FANUC 20-TA CNC control system delivers industrial-grade precision for large-scale turning operations with a swing capacity of 44.7 inches and an extended machining length of 320 inches. This control represents an industry-standard platform featuring a 9-inch monochrome monitor and 44-key keypad interface for operator interaction. The system supports 2-axis digital readout (X & Z coordinates) with multiple operation modes including MEM, EDIT, MDI, Machine Guidance, Manual/Handwheel, and Reference Return functions. The 20-TA incorporates advanced programming capabilities through Custom Macro B language for G-code development, with optional background editing functionality enabling program modifications during execution. Operator control is enhanced through triple electronic handwheels with multiplier switches providing sensitivity settings of 0.0001", 0.001", and 0.01" for precise manual and automatic turning operations. The system includes Constant Surface Speed (CSS) control as standard, conversational graphics programming, and full diameter/radius programming flexibility in both absolute and incremental modes. Compensation features address manufacturing precision through backlash error compensation and ballscrew pitch error correction from laser calibration data. The control manages 16 tool geometry offsets and 16 tool wear offsets with integrated tool nose radius compensation. Connectivity is facilitated through a built-in RS-232 port for part program transfer, supporting 63 part program storage with 40 meters of paper tape backup. Full CNC control extends to coolant and work light functions via M-codes, with optional power contactor control for accessory management.
