Roller Burnishing Tools

Swiss Superfinishing offers Roller Burnishing Tools. It is used to super finish bores and shafts. It is used on conventional drill machine and or turning centres. It starts from 5mm to 400mm. During burnishing process all peaks of component are plastic deformed in to valleys by cold process and we get surface roughness in range of 0.02 to 0.04 RA micron value. Special bearing size tools are manufactured viz. 6201, 6203 etc to get accurate size and good finish. Main advantage is that ovality is improved by 40 to 60 % and the surface hardness increases by almost 80 to 100 % on core depth of 20 microns. Main Applications: Pump/ Electric motor and covers, Fuel injection pumps, water body, rocker arms, door closers etc. 1) Avoid Honing & Lapping Tools for Blind Bore/ Bearing Size - Tools for Blind Bore: Adjustment range 0.05 to + 0.2mm, No Helix angle provided, Can be used in Bearing Sizes i.e. 6200 to 6211 (SKF/ FAG). 2) Tools for through Bore Burnishing: Adjustment Range -0.2 to +0.8 mm, Helix Angle provided for self-feed and Tool range 10 mm to 256 mm diameter.
