Cutters: SRB scraping roll finishing cutters can scrape when moving forward and roll finish when moving backward, in order to prevent blades scraping parts during roll finish, blades are pneumatically controlled for retraction. Since scraping and roll finishing are separated, rotation speed and feeding quantity of parts size can be set up independently, which can optimize working efficiency and reduce driving power.
SRM cutter heavy boring-semi heavy boring-fine boring design of ECOROLL Company can solve the problem of big margin cutting. 

The unique skiving & roller burnishing parameters of SRB cutter made by SANDVIK can be set independently, which optimizes the processing effect. 

The design of rough boring, semi-finish boring and finish boring of SRB cutter made by ECOROLL solves the problem of processing large-allowance workpieces.
