Skiving Roller Burnishing Tool (Sold Wll in Middle East)

Hydraulic SRB Tools

Operation: There is rough boring head on the top end, with three groups of indexable inserts (mechanical clamping) and three groups of carbide guide pad. Rough boring head cuts off most of material, behind with floated skiving head, in which installed with three groups (six pieces) of fine inserts. The skiving head reduces wavemark and corrects the deviation on the surface. The back part of the tool is roller burnishing head, with 6-40 rollers working on the internal wall of the hole, which can form the smooth surface and obtain the better profile. At the completion of processing, the skiving insert is shrunk under hydraulic control, while the roller can be also retracted to prevent from damage on the hole surface.   

Pneumatic SRB Tools

Operation: The tool moves forward for skiving, and backward for roller burnishing.

With 2 groups of insert on the top end, it can achieve high sizing precision and good shape control;

With 4 groups of guide pad, it can achieve the excellent guidance and balanced skiving, also prevent from scraping on the hole surface; the inserts are retracted by pneumatic control.

Features:

l  To be used for machining various tubes including cold drawn seamless steel tube, welded cold drawn tube, hot roller steel tube and cast steel tube.

l  Easily and rapidly adjust the sizes of inserts, guide pads and rollers. At the completion of processing, adjust cartridge by pneumatic control to prevent from damage on the hole surface.

l  Adopting the design with high efficiency, combining fine skiving and roller burnishing, and achieving one-off machining, it provides the tool with a long life and has a high efficiency of 20 times traditional honing machine and 5-10 times ordinary boring machine.

l  At the completion of processing, the surface hardness increases about 30%, the precision is up to IT8. Surface finish is up to Ra0.05-0.2μm.

l  To improve compatible precision, increase wear resistance and prolong using life of spare parts. After roller burnishing, oil cylinder becomes anti-corrosive and wear-resistant, and achieving a good surface finish, which prolongs the life of sealing ring or sealing parts.
