GCE 260-350 External/Universal


Precision Hydraulic Cylindrical Grinders

High Precision External & Universal Cylindrical grinders GC 260/350 are used in diverse production and tool room applications. Robust cast iron box structured design ensures high static and dynamic stability. Some of the standard features of these machines are

  • Dual-feed rates

  • Spark-off-timer selection

  • Single lever control for the fully-automatic-grinding-cycle

  • Wheel head & Work head having multi lobe hydrodynamic bearing Spindle for better accuracy and long life

Optional accessories like in process gauging makes these machines very cost effective for single operations, high productions.

Swing-down-type-internal-grinding head makes the Universal model an ideal choice for diverse application of various industries.          

Note:
Component drawing is must whenever taper grinding is required, both in case of Internal/ External grinding. MGT will study the drawing and provide appropriate solutions.
