Swiss Superfinishing offers Centreless Roller Burnishing Machines. It is used to super finish shafts with outer diameter ranging from 1.5mm to 45mm in steps. It is equipped with PLC Control & A.C., Variable Drive with timer. It is used for burnishing on following applications: Pump/ Motor Shafts, Mixer/ Food processor Shafts, Lock Shackle, Ceiling/ table fan Shaft, Wind Balancer Shafts, Engine Valves etc. The maximum deformation is in the range of 1 to 4 microns and the surface roughness is in the tune of 0.02 to 0.04 Ra micron value as well surface hardness increases by 60 to 100 % in core depth of 20 micron and hence increases life of shaft. Important parameter ovality is improved after burnishing, the machine is centerless hence no limitation on component length and even hardened components up to 60 HRC can be burnished by carbide rollers.
