Model Estarta 301 MV Centerless Grinder Offers Advanced Features For Precision Applications


PURCHASE, NY-The new Model Estarta 301 MV centerless grinding machine is designed with advanced technology features for reliable, accurate performance in a variety of precision grinding applications.

This high performance centerless grinding machine is built with a single-piece cast iron base and bed. Its cantilever grinding wheel spindle is constructed of chrome and nickel plated tempered steel that runs on high-precision ball bearings. The grinding wheel spindle is driven by a powerful 7.5 kW motor fixed to the base of the machine.

The regulating wheel headstock can be tilted + 5 degrees and axially displaced, allowing plunge grinding of parts with diameters and adjacent faces or shoulders. The regulating wheel headstock and workrest blade support assembly can swivel up to 2 degrees forward and 5 degrees reverse for grinding tapered parts without the need to profile the wheel. Infinitely variable regulating wheel speed can be optimized for each job with a potentiometer, even while the machine is running.

The traverse movement on both dressers is electrically driven by a DC motor for added precision. Diamond infeed movement is manual. When dressing the regulating wheel for throughfeed grinding jobs, the hyperbola is automatically obtained by correcting the diamond position. This ensures optimum contact with the part along the regulating wheel's generating line.

The Model Estarta 301 MV centerless grinder is available in two versions, a manual infeed machine and a servo motor infeed machine with Fanuc Powermate 0 controls.

The machine is built to handle workpiece diameters ranging from 1.5 mm (0.06") to 50 mm (2"). Maximum infeed grinding length is 125 mm (4.92").
