DAINICHI DLX-75A CNC LATHE

Technical Description

This CNC lathe features a **29.53-inch swing** capacity with a **machining length of 157.48 inches**, allowing for the handling of medium to large workpieces. The machine is controlled by a **Fanuc 20-TA CNC system**, a reliable industry-standard control providing precision and versatility. The Fanuc 20-TA includes a 9-inch monochrome display with a 44-key keypad, supporting 2-axis (X and Z) digital readouts for accurate machining. Its control capabilities encompass custom macro B programming for G-code, background editing during operation, and six CNC operation modes such as Memory (MEM), Manual Data Input (MDI), and Manual/Handwheel modes, allowing flexible programming and manual override. The control supports absolute and incremental programming, inch/metric units, and constant surface speed control, essential for consistent machining performance. The system facilitates easy part coordinate setup, 16 tool geometry and wear offsets, backlash compensation, and ballscrew pitch error correction based on laser calibration data, ensuring high dimensional accuracy. Additionally, it features full CNC control of coolant and work light functions via M-codes and incorporates self-diagnostics with on-screen error messaging for simplified maintenance. The robust CNC architecture also includes RS-232 communication for program data transfer and offers manual interrupt options like spindle and handwheel interrupts for safety and precision. This setup is optimized for turning operations requiring precision, repeatability, and adaptable control within a medium-sized lathe envelope.
