GOLD OD/ID GRINDER
Ultimate versatility with Non-Round capabilities

The 1632 Gold and 1612 Gold are the ultimate in CNC cylindrical grinders with OD/ID and non-round capabilities. These machines can automatically grind diameters, tapers, chamfers, radii, shoulders, and contours in one set-up and one continuous operation. The Gold grinders feature an innovative shear damping base design which provides superior damping, greater thermal stability, and improved static and dynamic stiffness.

The two models are customized to fit specific applications and are differentiated by a 12″ or 32″ between centers length and corresponding footprint. Both feature a FANUC CNC control. Available options include a programmable “C” axis work-head for non-round grinding, a power-operated swingdown ID system, and various wheel dressers.
