FA Tools for Deep Rolling Large Radii In The Thread Root

ECOROLL multi-roller tools are usually used for roller burnishing. Types G, R and RA machine cylindrical through and blind bores, stepped bores and cylindrical external surfaces including similar non-cylindrical surfaces. . RP, RK, RKA and RKAK tools are designed for plane surfaces, cones and spherical surfaces.  

RH/RHA tools deep roll fillets and chamfers. FA tools deep roll large thread root radii.

All ECOROLL multi-roller tools can be used on CNC turning, drilling or milling machines and machining centers or on conventional machine tools. They can be characterised by reliable functioning and high precision. Adjustment of diameters is very convenient, and only nominal lubrication is required. Futhermore, replacement of wear parts is very simple. This uncomplicated maintenance and short primary processing times enable significant time savings.

These deep rolling tools are therefore suited like no other kind of tool, for efficient and economical deep rolling of dynamically stressed external threads as used in e.g. the oil industry.

  • For use on CNC lathe
  • The FA tools are characterized by their solid design i.e. no deep rolling forces are transferred to the machine tool. Because the design is similar to a C-frame, the forces are absorbed by the tool.
  • Deep rolling forces of up to 60 kN are provided.
  • All plastically shapeable metals up to a breaking strength of 1400 N/mm² or a yield point of 1200 N/mm² are capable being deep rolled.
  • With automatic adjustment, conical threads can also be machined.
