Base: The base of "Pitroda" Hydraulically operated universal Cylindrical Grinders are made of close-grained castiron and are wel ribbed. The robust design of the body minimises vibration & distrotion. The guideways one side flat and the other 'V' type are precision hand scraped to match the corrosponding surfaces of the table slides.
wheel Head: Sturdy design to ensure maximum rigidity and smooth operations. Spindle made of nickle chrome steel is duly hardened, ground, and lapped. The spindle runs in "Phospherous Bronze Metal" adjustable taper bush bearings in oil bath. The spindle thrust load is taken by imported Double Acting Thrust Ball Bearing which is adjustable. Automatic lubrication is by oil splash lubrication systems. Drive is by means of "V" belts.
Work Head: The Work Head is built for grinding operation both with stationary and revolving centre 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.
Table: The table is composed of two parts (a) plain table (Bottom part) provided with a "V" and flat guides resting on bedways and (b) a swivel table (upper part) which can be swivelled 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.
Tail Stock: The adjustable spring loaded Quill travels in truely bored, reamed and honed tail stock. The tail stock travel smoothly all along the length of table right up to the work head.
Internal Grinding Attachment: (Extra equipment at extra cost). 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.
Coolant: A generous coolant supply is provided with an electric coolant pump fitted on coolant tank separately provided.
Electricals: The machine is supplied with electricains suitable for the supply of 400/440 V AC 50 Cycles, 3 Phase, Electric motors are of reputed make. The machine has push button switches, contactors, & Amp. Meter.
Standard Equipment: 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 centre Two.
Following Equipment at Extra Cost: Internal Grinding Attachment, Internal Spindle, Swivel of Wheel Head, Three point Steady Rest, Two Point Steady Rest, Additional wheel flange, True Chuck Flange, Revolving Centre MT-3 & MT-4 wheel Balancing Arbour, Wheel Balancing Stand, Radius dressing attachment, Angular dressing attachment.
