EG5: Cylindrical and conical outer surfaces, plane surfaces and bores
Characteristics
- Machining of external cylindrical and conical surfaces, external and internal plane surfaces as well as cylindrical and conical bores (a special type is required for machining conical surfaces).
- 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 up to 1400 N/mm2 and a maximum hardness of HRC = 45
- Can be used as right or left-handed tool
- Both directions of rotation possible
Advantages
- Short primary processing time
- Elimination of set-up times and downtimes
- No occurrence of dust and slurry
- Only nominal lubrication required (oil or emulsion)
- Stepless roller pressure adjustment using infeed support
- Consistent and controlled machining results through measurement of roller pressure
- Face of the roller free, thus enabling machining close to shoulders and other edges
- Roller head guidance without play and low-friction
- Universally useable through modular system
- Simple replacement of wear parts
- Two replacement rollers are included in scope of supply
Basic construction
- 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.
- The standard version contains a dial indicator for indirect indication of the spring force. As an option, the tools can be equipped with ECOsense process monitoring for external display of the spring force.
- 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 α.
