Manisha machinery provides centreless throughfeed superfinishing machine. This centreless throughfeed superfinishing machine has following features which include: faster, cheaper, easier and better. The wide scope of the super finishing methods is founded on its economic operation, its cleanliness and the extraordinary results achieved in improving surface quality and shape. Surface roughness values obtained are remarkably low. Shape deviations such as feed marks, chatter marks and out of roundness are largely removed. Technical specifications of this superfinishing machine include: model - mha 400: dia range - 3-25 mm; number of heads - 4; feed rate - 2 m/min; and roller dia - 125 mm. Technical data: length - 1330 mm; width - 1500 mm; height - 1900 mm; net weight - 1050 kg; capacity - 3 hp; air consumption [nm³/hr.] - 10-12; amplitude - adjustabvle from ±1.5 to ±3 mm. . Centreless throughfeed superfinishing machine finds its applications in: axes of all kinds, especially those designed for noise-critical bearings as used for the drive of tape recorders, etc., guide columns, piston rods and plungers for pneumatic and hydraulic drives, tappets, rocker arm shafts, pistons and piston pins for internal combustion engines, sewing machines parts such as needle bars and spindles, syringe pistons, etc. For longer life and lower noise level of bearings, superfinishing is must, which improves roundness. The machine is not complicated and almost maintenance free.
