Hydraulic Surface Grinder

Specification

The working table executes only longitudinal movements, This ensures full contact and support from the machine bed, even in the table limit position. V and flat guide ways are laminated with Turcite’B’to guarantee smooth table movement regardless of the load on the table.

The column carries out only cross feed movements, this guarantees uniform contact between the column slide and machine bed in any column position. The column slide is guided by box type Turcite ‘B’ laminated ways, hand scraped to obtain smooth stick slip free movements.

Vertical slide ways and the grinding wheel, creating a perfectly perpendicular movement of the spindle in relation to the working table, The housing construction is also designed for better rigidity.

The cartridge type spindle is supported by class 7 super(CP4) precision angular contact ball bearings, preloaded and select-fitted into spindle cartridge. This will guarantee a maximum run out of 0.002mm for stable and accurate grinding, All the spindles are assembled at Prayosha skilled and experienced technicians in temperature-controlled clean room. The result is a spindle that will provide years of trouble-free service with minimum temperature changes, noise or vibration.

Centerless Grinder

Specification

• BED Made of high grade cast iron provided with strong ribs for rigidity and a large Inverted prismatic Guide and Wide track, For the table. All the guide ways are carefully hand scrapped to ensure high accuracy.
• DESIGN: designed to grind cylindrical parts at high production rates and close tolerances straight shoulders & taper parts can be ground with equal ease suitable for hardened and unhardened steel, brass , copper, aluminium, or another materials.
• GRINDING WHEEL HEAD: The grinding wheel spindle is made of hardened and ground nickle chrome alloy steel. It runs in oil chamber on Taper roller bearing or on bush as required. They are sturdy and strong enough to permit heavy duty grinding at high speeds and assure superior surface finish & accuracy.
