TNC-L32 : Two Axis Lathe Controller
TNC-L32 is an offline Lathe Machine Controller with a Handheld Pendant and remote Display, adding a 3rd axis to drive a Servo spindle headstock via Encoder input.
Overview
The TNC-L32 is an offline two-axis controller for a lathe, with an optional third axis to drive a servo spindle headstock directly.
Where a conventional lathe leaves spindle speed to a separate VFD and belt-and-pulley range, the TNC-L32's third axis output can drive the headstock itself as a servo axis ? useful for threading and other operations where spindle position, not just speed, has to be coordinated with the other two axes. An encoder input supports feeding spindle speed back from an induction or DC motor-based headstock even where the headstock itself is not servo-driven. A handheld pendant with its own remote display handles jogging and setup away from the panel.
Motor outputs are differential step and direction for a stepper or servo drive per axis, with independent maximum velocity and acceleration on each. Programs load from a USB thumb drive and the machine runs independently of a PC once loaded.
Where the TNC-P32 is the two-axis dotpeen marking member of the range, the TNC-L32 is built for lathe control, with the spindle-headstock axis as its distinguishing feature.
