Description: CENTRELESS THROUGHFEED Centreless throughfeed superfinishing machines are faster, cheaper, easier and better. The wide scope of the superfinishing 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. These centreless superfinishing machines have a wide spectrum of applications. Axes of all kinds, especially those designed for noise-critical bearings as used for the drive of tape recorders, 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 as well as syringe pistons. For longer life and lower noise level of bearings, superfinishing is a must, which improves roundness. The machine is not complicated and almost maintenance free. It gives troublefree operations for years. Specifications: model - MHA 400: dia range - 3-25 mm; number of heads - 4; feed rate - 2 m/min; and roller dia - 125 mm.
