Srb machines offers mode11gm-200 precision bore grinding machine. The machine bed 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. The machine has a rigid work head. High roundness accuracy of 0.002/0.001 /0.0005 mm could be achieved through alloy steel spindle running on high precision antifriction bearing. Job holding on hydraulic actuation system comes with diaphragm chuck. Internal grinding head is mounted separately on the bed. It moves on preloaded antifriction linear guideways for accurate dressing and dressing compensation. Apart from belt-driven spindle, high frequency spindle can also be used. The slide moves on the hardened and ground pre-loaded roller guideways and it guarantees the repeat positioning accuracy of 2 m. It also provides the stick slip free movement. Automatic infeed cycle consists of rapid infeed, coarse feed, dressing, fine feed, spark out, and rapid retraction. At any instance there is full contact of the moving sideways with the fixed slideways 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.
