Cylindrical Grinders

Machine Information

Many models available. Please contact us for more information.

The Supertec Series of CNC cylindrical grinding machines have been designed for ease of operation while continuing to be some of the most reliable machines in their class. These machines offer solutions that satisfy the user’s need for a wide variety of applications including toolroom or production environments. Models are available in many capacities between centers, center heights, and a choice of straight wheelhead or angular slide wheelhead. These machines utilize either the Fanuc control or other controllers that support a wide selection of highly-automated options.

Machine base

The heavily ribbed box type base is made of Meehanite casting, providing excellent rigidity to ensure machine stability. Optimum distance between the guide ways offers excellent table support to increase X axis positioning accuracy and repeatability

Workhead

The sturdy rigid-designed workhead equipped with precision bearings is electronically controlled giving variable spindle speeds. Workhead swivels 90 degrees counterclockwise to 30 degrees clockwise for various grinding operations. A combination live and dead type spindle allows for quick changeover from center to chuck operation or vice versa. A dual oil seal and cover prevents coolant seepage into the workhead.

Tailstock

The design of the tailstock is both rigid and robust. Housed in a Meehanite case body, the hardened nitralloy steel sleeve is designed to carry a MT4 center for G32/G38 and a MT3 Center for G20P/G25P. Movement of the sleeve is adjusted by a knob to give a light or heavy load. An optional hydraulic tailstock with foot pedal is available for easy loading and unloading of parts.

Wheel Spindle

A combination of hydrostatic and hydrodynamic bearings, surrounded by a high pressure oil film, eliminates metal to metal contact to provide high rigidity as well as high vibration damping performance. A pressure switch interlock prevents spindle start up until oil pressure is established. This pressure switch interlock also stops the spindle if oil pressure fails. Both features ensure high accuracy and longer spindle life.

Saddle

The double V guideways are hand scrape dand Turcite coated, and utilize an automatic lubrication system, precision ballscrew, AC servo motor and a 0.001m (0.00020”) linear feedback system. This combination allows for a smooth movement of the wheelhead which delivers a longer way life with superior positioning accuracy and repeatability. The enlarged and properly sloped drainage troughs under the wheelhead base help to control thermal growth and provides the rapid coolant draignage needed during heavy grinding cycles.
