The adjustable spring loaded Quill travels in truly bored, reamed and honed tail stock. The tail travel smoothly all along the length of table right up to work head.
A generous coolant supply is provided with an electric coolant pump fitted on coolant tank separately provided.
The table is composed of two parts (a) plain table (bottom part) provided with a “V” and flat guides resting
on bed ways and (b) a swivel table (upper part) which can be swiveled easily and rapidly by means of a fine
adjustment screw on the right hand side of the table.
Angular setting is effected with a scale Longitudinal hand travel of the table is by rack and pinion arrangement and automatic travel is mechanically operated with a separate electric motor.
*Internal Grinding Attachment
The Hine type internal grinding attachment is conveniently located on the wheel head. The said attachment driven with independent electric motor through a flat endless belt giving the highest efficiency. The spindle of the internal attachment is suitable for grinding cylindrical & tapered holes.
The machine is supplied with electricians suitable for the supply of 400/440 V AC 50 Cycle, 3 Phase, Electric motors are of reputed make. The machine has push button switches, contactors, & Amp meter.
The work head is built for grinding operation both with stationary and revolving center work head spindle runs in oil body and fitted with “super Quality” imported taper roller bearings OR (at extra cost) adjustable gunmetal bush bearings. The drive to the work head spindle is by “V” belts.

PUI 800 Cylindrical Grinding Machines
The base of ‘’PITRODA” hydraulically operated universal cylindrical grinders are made of close-grained cast iron and are well ribbed. The robust design of the body minimizes vibration & distortion. The guide ways one side flat and the other ‘V’ type are precision hand scraped to match the corresponding surfaces of the table slides.
Sturdy design to ensure maximum rigidity and smooth operations. Spindle made of nickel chrome steel Is duly hardened, ground, and lapped. The spindle runs in “Phosphorous Bronze metal” adjustable taper bush bearing in oil bath.
Electric motors, Electric panel Box, Belts, Coolant pump fitted on tank. Grinding wheel, Grinding wheel flange attached with the machine, dressing attachment (without diamond) dead center two.
