Bhambra Engineering Works, one of the largest producers of bright bar machinery in India, has come up with bar peeling machines. The bar to be peeled is supported between an entry guide and steady rollers. The cutting tool is mounted in a cutter head which in turn is fixed on a revolving spindle. The bar is moved by feed rollers against the revolving cutter head.

 

Head stock is a rigid casting containing a revolving main spindle driven through ‘V’ belts and shifting gears from the main motor. A cutter head is fixed to the main spindle. The head is designed to hold a cutting tool and also rollers for polishing the work. The spindle speeds can be varied by means of changed gears.The feed gear box is also a rigid casting. The feed rollers are operated by a motor through ‘V’ belts and worm gear. The rollers feed the bar against the revolving cutter head. The feed rate of the bar is varied through dimmer stat. All the shafts are mounted on bearings.The bed is a cast iron base on which the feed gear box and head stock assemblies are mounted. The main motor is fixed on the left rear wall and feed gear box motor on the right rear side of the bed.

 

The cutter head is a cast steel part. To thiffs, three polishing rollers (HCHCr) and one carbide tool are fixed. The entire assembly is bolted to a face plate which in turn is threaded (clockwise) to the main spindle. The cutter head will rotate with the main spindle while the bar is fed longitudinally.
