Permit to have a good surface finish. Smooth the diameters, without improving the turning geometry.
Main advantages
Allow the smoothig of the diameter
The 3 rollers provide a better surface finish
No radial efforts or pressure on the workpiece
Burnishing dies
These burnishing dies permit to smooth the diameters.
They work without radial efforts and no pressure is exerted on the workpiece, even for small diameters.
The three rollers will give a better surface quality, without improving the turning geometry, however.
The rollers will just follow that geometry. It is therefore important to have a good tuning job done, as far as concentricity and cylindrical shape are concerned.
The peripherical speed of the workpiece must be about 20 meters/minute. The speed is smaller when the material to be smoothed is very hard.
The indicative value for the feed is 0.2 to 0.5 mm/revolution.
Die holders, adjustable
The die holders, type R, permit to mount our adjustable rolling dies on all types of automatics.
The assembly on the machine will be effected either with a clamping collet or directly into the collet housing with the help of a clamping cone.
