Deep Rolling Tools Types RH/RHA, EF45, FAK120, FAK025/EF90 (For HG tools please see pages 2.13 to 2.16)

Application: RH

● For use with CNC-controlled or conventional lathes ● Complete processing in one setting ● Symmetrical construction allows either right- or left-hand operation ● Rotates in either direction

RHA

Individual tool applications:

EF45

FAK025

FAK120

RH/RHA

● For internal and external fillets ● Deep rolling with the plunge-in process ● Suspended rollers for even force distribution independent of production tolerances ● Spring-mounted tool body provides constant rolling force (compensates for positioning errors and production tolerances) ● Process requires a maximum of 15 rotations

EF45

● One suspended roller ● Deep rolling with the plunge-in process ● Rolling force monitored by a dial gauge or an inductive measuring system

FAK120

● Deep rolls fillets with the plunge-in process ● Deep rolls contours or large fillets with the infeed process ● Deep rolls thread root radii ● Axial floating roller for the plunge-in process ● Roller unit includes axial/radial bearings for the in-feed process ● Rolling force monitored by a dial gauge or an inductive measuring system

FAK025/EF90 ● Deep rolls internal thread root radii (FAK025) or external thread root radii (EF90) ● Deep rolls within the machine’s thread cycle ● Axial floating roller compensates for marginal positioning errors ● Automatic roller angle alignment ● No conversion necessary to machine either right- or left-handed threads ● Roller made to fit component’s thread root radius ● Integrated pre-loading mechanism, no further X-axis adjustment necessary

EF90

The RH/RHA deep rolling tools consist of two main components:

Tool Design: RH/RHA

● Specially designed per workpiece dimensions ● Screwed into the tool body

Tool Design: EF45, FAK120, FAK025/EF90 EF45

These deep rolling tools consist of a tool body equipped with a shank, a spring assembly that allows the roller head to move with no play and very low friction, and a dial gauge that indirectly indicates the spring force. An optional inductive measuring system externally displays the rolling force.

The roller head is attached to the flexible, spring-loaded section of the tool body. The flexible roller holder moves in response to the radial or axial rolling forces on either side of the tool.

The roller is suspended within the roller holder with a slide bearing bolt. In addition, the roller mount swings such that the roller automatically adjusts to the thread pitch. A set screw limits the roller’s pivoting angle.
