OUTPUT SHAFT – FRB SCHEMA 1163/98

• MACHINING: Grinding of output shaft.
• REQUIRED QUALITY
  • Circolarity: 0,005 mm. (0,002 mm. – obtained data)
  • Cilindricity: 0,005 mm. (0,002 mm. – obtained data)
  • Concentricity: 0,010 mm. (0,003 mm. – obtained data)
  • Roughness: 0,8 (0,5 – obtained data)
• ORIGINAL TOOLING UNTIL 1998
  • Rotation of workpiece on dead centers.
  • Driving with a 3 sectors membrane.
• TECNOLOGIE FRB TOOLING SINCE 1998
  • Rotation of workpiece on revolving centers.
  • Driving with self-compensating face driver with revolving body.

RESULTS:

1. QUALITY : This system of equipment has permitted not only to be included in the required quality range, but to abut on values of 50% of the tolerance. These qualitative results have been possible because, by using revolving centers, there is no more friction between the centres of the workpiece and the centers. Radial efforts have been eliminated by replacing sectors clamping with self-compensating face drivers.
2. ADVANTAGES: By this system, compared to original tooling, lubrication and wear of the centers are eliminated.Moreover it is possible to adjust the peripheral speed of the workpiece from 12-15 meters/1′ to 40 m/1′ and the result is that machine time is reduced and it is possible to obtain better working conditions of the wheel with consequent reduction in frequency of dressing.
3. FRB face driver with revolving body is equipped with micrometrical adjustment for setting up on the machine.

The feeder FRB and equipped with recording micrometer for the development the machine.
