Main function:
This series of superfinishing in the way of centerless through-feed machine the surface,including the needle roller,cylindrical，roller,taper roller,ring of bearing, oil-needle, piston, spool etc.
After grinding process,the superfinishing process can improve the surface quality & the geometrical precision;the machines have high efficiency,precision,& reliability etc.widely used in the industry of the beating,car,motorcycle. pin valve oil pump and hydraulic parts etc,especially suited for superfinishing the crown of taper roller & cylindrical roller.
Through special designing & processing the guide roller can receive several crown types of rollers,such as arc fullcrown type,logarithmic type.
