EG5-08F, EG5-40M Tools for contours, concave fillets, groove bed machining and short bores
- Can be used on CNC or conventional lathes.
- Machining in a chuck.
- Attainable surface finish Rz < 1 micron (Ra = 0.2 micron).
- Processing of all metallic materials with a tensile strength of 1400 N/mm2 and a maximum hardness of HRC = 45.
- Universally useable modular system.
- Can be used as right or left-handed tool.
- Both directions of rotation possible.
- Elimination of microscopic grooves and simultaneous introduction of residual compressive stress
- Short primary processing time
- Elimination of set-up times and downtimes
- No occurrence of dust and slurry
- Only nominal lubrication required (oil or emulsion)
- Roller head guidance without play and low-friction
- Stepless adjustment of roller pressure
- Consistent and controlled machining results through measurement of roller pressure
- Simple replacement of wear parts
- Type EG5 single roller burnishing tools consist of a tool body equipped with a tool shank, a spring assembly that allows the roller head to move with no play and very low friction, and a gauge that indicates the burnishing force as measured by spring deflection.
- An optional device transmits the values by cable or wireless signal to an external indicator.
- The roller head is attached to the flexible, spring-loaded section of the tool body. It consists of a cage, which contains and guides the burnishing roller, and a support roller with a large-scale needle bearing.
- The cage also contains two spare rollers.
- Tool design includes fixed roller clearance angle ∝.
Roller burnishes groove flanks on the face or circumference and bores.
- With diameters of 8.5 mm and larger
- Max. rolling depth: 20 mm for diameters of 8.5 mm and larger
- Tool body’s spring assembly positioned parallel to workpiece surface.
- Floating roller head attached to the tool body’s fl exible, spring-loaded section.
- Machining cylinders with subsequent radius to the plane surface.
- Suitable for low and medium strength materials.
- Extremely narrow roller.
- Tool body’s spring assembly positioned parallel to workpiece surface.
- Roller head attached to the tool body’s flexible, spring-loaded section.
- Extremely narrow roller with an integrated four-point bearing.
EG5-40M-45°: Roller burnishes cylindrical surfaces with connecting fillet radii up to the workpiece face.
- Tool body’s spring assembly positioned at a 45° angle to workpiece surface.
