Tormach PSG 612 Advantages


Each PSG 612 is engineered for a lifetime of worry-free operation. The rigid cast iron frame features a stout column that resists wheel deflection. Slide ways are hand scraped dovetails with taper gib adjustments, and each sliding surface is bonded with a low friction PTFE-filled acetyl co-polymer, similar to Turcite® or Rulon®. A single shot lubrication system distributes oil to all key surfaces with one pull.


Like all Tormach products, the PSG is backed with a standard 12 month warranty and our industry-best technical support. With a space-saving footprint, simple operator’s interface, and robust electronics, the Tormach PSG 612 is ready to take on your next short run or small batch surface grinding job today.
