Surface Grinder with Overhead Dresser Performs Rough, Fine Grinding

As part of its Wizard series of surface grinders, Kent International USA offers the WMA1 programmable downfeed grinder with automatic compensate overhead dresser. Integrated in the automatic grinding cycle, an AC servomotor with ballscrew drives dressing diamond feeding, while the dressing stroke is hydraulically driven with adjustable passing speeds. Interval, dressing amount, dressing increments and wheelhead compensation feed rates can all be keyed in with 0.000050" minimum increments. Dressing parameters can be set for both rough and fine grinding.

Castings are made of high-quality ribbed cast iron tempered to achieve extreme rigidity, the company says. The machine’s X and Z slideways are laminated with Turcite-B to ensure smooth movement regardless of the part weight on the working table. The spindle is supported by preloaded, P4 angular contact ball bearings to guarantee a maximum runout of 0.00002" for stable and accurate grinding. 

A Mitsubishi programmable logic controller with a 6" color LCD touchscreen panel constitutes the grinder’s main control. The control’s ability to store the previous grinding cycle in memory is designed to boost efficiency by enabling operators to repeat previous operations by hitting the cycle start button.

Three other models in the Wizard series include the WM1 programmable downfeed surface grinder, the WM2 programmable downfeed and cross-feed surface grinder, and the WMA2 programmable downfeed and cross-feed surface grinder with automatic compensate overhead dresser.
