GMI: Cylindrical bores, diameters 3.70 mm to 21.00 mm
Through hole; diameters 3.70 – 6.00 mm
Blind hole; diameters 6.00 – 21.00 mm
Characteristics
- Can be used up to tolerance class IT8
- Suitable for all metal materials up to a tensile strength of 1400 N/mm2 and a maximum hardness of HRC ≤ 45
- Can achieve a surface quality of Rz < 1 μm (Ra ≤ 0.1 μm)
- Application ideal for sliding headstock lathes, but also on CNC controlled turning, drilling or milling machines, machining centers or conventional machine tools
- Machining in pushing motion with clockwise rotation
- Available with straight shank
- Parameter recommendation:
- Max rotary speed: up to 250 m/min
- Feed: 0.05–0.3 mm/rev per roller
Advantages
- Compact design for applications in machines with limited workspace
- Short cycle time
- Diameter adjustment is easy and repeatable
- Requires minimal lubrication (oil or emulsion)
- Tool automatically contracts upon retraction, preventing damage to the roller burnished surface
- Wear parts are easy to exchange
