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.
