MORI SEIKI SL-4T CNC LATHE

This CNC lathe features a robust 3 HP spindle motor operating at 60 Hz and 220 volts, delivering reliable performance for precision turning applications. The machine is equipped with a 12-station turret configuration, combining 8 standard tool stations with 4 additional stations for expanded tooling flexibility. An 8-inch chuck provides secure workholding for a wide range of part sizes. The control system is powered by Fanuc 6T, a fixed-software, closed-loop CNC renowned for its high accuracy and reliability in early CNC turning centers. The Fanuc 6T control utilizes high-speed microprocessors and custom LSIs, supporting advanced functions such as programmable logic control, self-diagnostic capabilities, and real-time monitoring of key parameters like acceleration/deceleration time constants and rapid traverse speeds via the CRT display. Input/output signals are managed through dedicated control PCBs, supporting up to 96 input and 64 output signals for comprehensive machine integration. The control does not feature modern work coordinate offsets; instead, tool offsets are set individually per tool, requiring careful setup for accurate tool positioning. The machine’s sturdy construction is reflected in its substantial 13,000 lb weight, ensuring stability during heavy cutting operations. This combination of power, precision, and proven Fanuc 6T control makes the lathe suitable for demanding production environments requiring consistent accuracy and durability.
