VICTOR 70320DCL CNC LATHE

Technical Description

This CNC lathe features a robust design with a maximum swing of 70.39 inches and a machining length of 320 inches, making it ideal for large-scale turning operations. Equipped with the Fanuc 20-TA control system, the machine delivers reliable and precise CNC performance, supporting both manual and automated machining tasks. The Fanuc 20-TA control offers a 9-inch monochrome monitor and a 44-key keypad for intuitive operation, with a digital readout for X and Z axes. It supports both diameter and radius programming, as well as absolute and incremental modes, and allows for inch or metric input and display. The control system includes standard features such as constant surface speed (CSS) for both manual and automatic operations, backlash error compensation, and ballscrew pitch error compensation for enhanced accuracy. The machine supports up to 63 part programs and offers a built-in RS-232 port for easy program transfer. Tool management is streamlined with 16 tool geometry and 16 tool wear offsets, including tool nose radius compensation. The Fanuc 20-TA also provides multiple CNC operation modes—MEM, EDIT, MDI, Manual, Handwheel, and Reference Return—along with auxiliary modes like Dry Run, Single Block, and Optional Block Skip. Manual interrupt functions allow for handwheel and spindle interruption during automatic cycles. The control features triple electronic handwheels for simultaneous manual and automatic turning, with a multiplier switch for sensitivity adjustment. Full CNC control of coolant and work light functions is available via M-codes, and the system supports background editing of G-code programs during execution as an optional feature. Self-diagnostic capabilities provide on-screen error messages for efficient troubleshooting.
