CNC Cylindrical Grinders

This programmable in-feed on the CNC grinders is suitable for grinding straight, formed, tapered and internal type workpieces. The worktable feed movement is controlled with hydraulics which has infinitely variable speed, and this movement is monitored by the controller.

The CNC is manufactured by GE FANUC

The GE/Fanuc CNC controller operates the in-feed on the O.D. & I.D. movement of the wheelhead. The system has the necessary hardware to be fitted with an In-process gauging system to complete automatic sizing of the

Programming is a "G" code format and the storage is large enough that multiple programs can be stored. The system can be programmed to plunge or traverse grind with a course and/or fine feed, plus spark-out. This will give you the flexibility needed to keep up with today’s technology in the manufacturing industry.

All of ECOTECH'S Universal Cylindrical Grinders have heavy aged cast iron construction, that have been precision machined and hand scraped. With a Hydro-dynamic spindle on the wheelhead, and the Hydro-static lubrication system on the table, you will have many years of trouble free operation and high accuracy.
