GZ Roller Burnishing Tools

The ECOROLL internal roller burnishing tool type GZ is used together with the SK peeling head for finish machining cylinder liners.

• Skiving and burnishing are separate processes.
• For use on deep-hole boring machines with BTA boring systems.
• After machining the roller head automatically collapses; the tool can be retracted quickly without damaging the work piece.
• For short cylinders (L/Ø ≤ 15) complete machining with SKIOC and GZ tools on CNC-lathes and machining centers possible.
• All plastically shapeable metals up to a hardness of 42 up to 45 HRC are capable being burnished. 

• Diametrical tolerances of IT8 or IT9 and surface finish of R_z < 1 micron attainable.
• Push or drag machining possible.
• Short primary machining time.
• Convenient adjustment of diameter.
• Reliable method; great precision.
• Simple replacement of wear parts.
