Supertec Machinery’s Mini Genie cylindrical grinder is designed for shops with limited floor space, with a footprint of 78" × 78" (43 sq. ft.). The machine provides grinding diameter capacity of 9", a distance between centers of 8", and a work load capacity of 44 lbs between centers (11 lbs chucked). The wheelhead uses an NN contact taper needle roller bearing spindle with a 20" × 2" grinding wheel and 10-hp spindle motor, enabling greater stock removal rates. Featuring infinitely programmable speeds, the workhead can reach 600 rpm. The machine can grind materials such as cast iron, Inconel, carbide and chrome. 

Equipped with a Mitsubishi M80 control and Supertec’s I-Grind conversational shopfloor language, the grinder is said to be easy to program. The graphic display screen allows the operator to review the part program prior to grinding and make any required adjustments. The Mitsubishi M80 (and optional FANUC Oi-TF) control can be interfaced to a variety of measurement systems such as touch probes and automatic sizing devices as well as robotic and gantry-style automatic loading systems.

The Mini Gene comes in two styles, a plunge model with the wheelhead set at 90 degrees and an anglehead model with the wheehead set at 20 degrees. The anglehead is well-suited for faster stock removal and a better surface finish on face and shoulder grinding applications, the company says.

A Heidenhain 0.000002"-resolution linear scale is used for improved accuracy and repeatability, enabling the achievement of 0.0001" or better tolerances, according to Supertec. Both machine axes use linear guideways for smoother more accurate movement.

Other standard features include a full enclosure, an infinitely variable workhead, a coolant system with paper filter and magnetic separator, and a taper-adjustable tailstock.
