BASE
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 way-one side flat and the other V type are precision hand scrapped to match the corresponding surfaces of the table slides. Longitudinal hand travel of the table is by rack and pinion arrangement and automatic travel by hydraulic. Thechange over from manual lubrication of the longitudinal and cross slide way, two oil pockets and groves are provided, one at each end.
HYDRAULIC SYSTEM
This consists of a general pump, oil tank, piping, etc. All conveniently housed in the base. The hydraulic is made of graded cast iron and is honed.
WHEELHEAD
The rigid wheel head spindle is made of EN24 or 353 steel hardened and ground. It runs is adjustable type bush bearing. The drive to the wheel head transverse is cross direction is on precision hard scraped ‘v’ and flat guide way. He spindle is tapered (5??) at the front to receive the wheel flange. Oil hole are provided for lubrication of the bearing surfaces.
WORK HEAD
The work head spindle is made of nickel chrome steel EN-24 or 353 hardened & ground. Run is gun metal bush bearing or in angular contact bearing. The drive to the work head spindle, which has MT-3 by step ‘V’ pulley. The speed obtained through this pulley can be reduced by another bigger size pulley provided in the work head housing. He work head is built for grinding operation both with stationary center and revolving spindle. Oil cups are provided for lubrication.
INTERNAL GRINDING ATTACHMENT
The spindle of the internal grinding attachment which is suitable for grinding cylindrical and tapered is made of 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 independent motor through endless nylon flat belt. The hinged type internal grinding attachment is conveniently located on the wheel head so the is can be easily swing into position.
