R-Grind
Cylindrical Grinder
R-Grind
The massive machine bed design of this Cylindrical Grinder with stable ribbing assures that even heavy components will have optimal results for surface roughness and dimensional accuracy. The hydrostatic spindle bearing and tailstock allow for extremely good isolation of machine vibrations and therefore provide excellent surface finish (R-Grind 20x). Low maintenance due to automatic slide and headstock lubrication. 8-way graded belt drive in the headstock for broad range of speed control. Infinitely variable table feed by hydraulic drive with “soft-stop” at the end of traverse. Rapid traverse for the spindle.
Available models include the 1565, 1580, 15100, 15120, 15150, 1765, 1780, 20100, 20120, 20150,20160, 20180, 20200, 25200, 25250, 25300, and 25400 and tables from 11×25″ to 19×156″.
