Precision Bore Grinding Machine

Model No. :-
IGM-200L
IGM-200H

Machine Bed:
It is made of high grade cast iron duly seasoned adequately ribbed with box structure design which provides high rigidity, strong enough to prevent distortion and wear.

Work Head:
The machine has a rigid work head. High roundness accuracy of (0.002 mm/ 0.001 mm) could be achieved through alloy steel spindle running on high precision antifriction bearing. Job holding on hydraulic actuation system diaphragm chuck/ shoe centreless.

Internal Grinding Head
It is mounted separately on the bed. It moves on preloaded antifriction linear guide ways for accurate dressing and dressing compensation. Apart from belt driven Spindle, high frequency spindle can also be used.

Infeed System
The slide moves on the hardened and ground preloaded roller guide ways and it guarantees the repeat positioning accuracy of 2 micron. It also provides the stick slip free movement. Automatic infeed cycle consists of Rapid infeed, Coarse Feed, Dressing, Fine Feed, Spark Out, Rapid Retraction.

Slideways
At any instance there is full contact of the moving sideways with the fixed slide ways to achieve maximum rigidity. Slideways are coated with antifriction material (TURCITE) with high vibration absorption and very low friction factor, avoiding stick-slip. This improves the life of slideways.

Electrical Panel/Power Pack/Coolant Unit:
These are housed outside the machines as separate units to facilitate easy maintenance. Electrical cabinet is Integrated with machine. HYD& Electrical equipment is of excellent quality and ensures troubled free and life-long service
