Background

The Tormach microARC 4 provides high-precision 4th axis machining in a compact footprint. Designed to fit on all of our machines from the PCNC 440 to the 1100M/MX, it reduces both operator workload and cycle times with a low maintenance harmonic drive. Using Tormach's new hollow shaft stepper motor design, long stock can be passed all the way through the chuck, harmonic drive, and motor to enable high volume production without reduced yield from pre-cutting stock into short lengths. With flexible mounting options designed in, it can be used on either the right or left side of the machine table.
