Cincinnati 220-8 Centerless Grinder

The Cincinnati 220-8 centerless grinder is an excellent choice for high precision and high production grinding applications.  With a footprint not much larger than the #2OM machine, the 220-8 has drastically more mass and static stiffness. This allows for heavier stock removal and higher precision grinding. The 220-8 can also accommodate larger diameter and longer parts when compared to a #2OM.

Allways Precision has a large variety of upgrades to improve upon the 220-8’s already impressive capability. From CNC wheel dressing systems to full turnkey automation packages, we want to build the right machine for you. Reach out to us today to find out more.
