The base is made of close-grained cast iron and is well ribbed. It is made particularly heavy to prevent vibration and distortion the guide ways - one side flat End the other V type are precision hand scrapped to match the corresponding surfaces of the table slides. The table moves on V & flat bed with turcite guide ways. The table is driven by high precision pre-loaded ball screw directly coupled with servo motor by precision coupling. Dust proof guard is provided on X•Z axis slide to fully protected from dust particle. equipped with auto lubrication system

Hydraulic System

Solenoid valve and proxy operated very smooth Hydraulic system, This consists of a standard pump, oil tank, piping, etc. All conveniently housed in the base. The hydraulic is made of graded cast Iron and is honed.

Internal Grinding Spindle

The spindle of the internal grinding machine which is suitable for ID cylindrical and tapered grinding, Spindle is made from EN-31 and is ground. It runs in preloaded magneto ball bearings-two in the front and two is the rear. The drive to the spindle is by an independent motor through endless nylon flat belt.


It has a rigid universal work head. It has cartridge type spindle. Swivelling of± 45° is possible. The work head spindle is made of nickel chrome steel EN Material hardened & ground. runs in P-4 class antifriction precision Angular contact bearing. Work head speed is variable and controlled by AC drive

Dressing Unit

The dressing unit consists of a single point fixed dresser which is capable of profile dressing as well as straight dressing. Diamond Roller dressing with spindle for wear less and accurate dressing available as Optional accessories


Generous coolant supply is provided with an electrical pump fitted on a separate tank, measuring approximately 15" x 15" x 12" (L.W.H.) and having a capacity of 36 liter water.
