GRINDING METHODS:

SPINDLE-HYDRODYNAMIC BEARINGS   DRIVING SYSTEM
 
Use of hydrodynamic bearings in the wheel spindle insure steady grinding and greater accuracy in the ENM grinding machines.   Use of grinding class leading screw which is high accuracy, high power and long life in the driving system. It insures the wheelhead's steady driving and greater repeatability.

SPECIAL NOTE:
All machines with 355 mm wheel can swivel +/-15• .Only 270 mm swing machine with 405 mm wheel cannot swivel +/-15', 300,350 and 380 mm swing machines with 405 mm wheel can swivel +/-15'.
M:
Table traverse and wheel head cross feed are all manual.
A:
Table traverse is hydraulically driving. Wheelhead cross feed is manual.
H:
"A" with wheelhead rapid approach and retraction. Wheelhead cross feed by manual.
AGC:
"H" with wheelhead rapid approach and retraction. Wheel head cross feed by auto.
DAS:
"AGC" with automatic sizing device.
Our grinding machines can be designed and installed for most any production requirements with special equipment.
