High-Precision 4th Axis Machining in a Compact Footprint

TORMACH INC. is offering the microARC 4, a device that allows high-precision fourth-axis machining in a compact footprint. The microARC 4 works with all Tormach machines, from the PCNC 440 Mill to the 1100 M/MX Mill, and it is available at an affordable price. microARC 4 reduces both operator workload and cycle times with a high-quality, low-maintenance harmonic drive. The drive provides extremely precise motion control, coupled with much higher rapid speeds than a worm-drive unit. The main features of the microARC 4 include: – Near-zero backlash levels because of the harmonic drive system; compared to a similar size worm-drive fourth-axis unit, the microARC 4 achieves anywhere from a 400%-600% reduction in backlash.
