With a roundness tolerance of 0.0015mm and eccentricity tolerance of 0.0025mm...
The Tecnologie FRB range of Face Drivers for use on Cylindrical Grinding Machines used for driving hardened steel shafts of up to 63Hrc are sure to be able to meet all of you requirements.
A 90Kg axial thrust from the live centre side is sufficient to drive the shaft. We can also supply an FRB live centre to obtain shaft roundness within 0.0015mm.
Using their patented integrated balance-type self-compensating system (which is also used on the face drivers for shaft turning) this system enables highly sensitive self-compensation of the driving pins. As a result the face driver has considerable drive and a high concentricity capability.
- Featuring the FRB patented 4-blade mechanical balancing system.
- Provided with a fixed center for maximum component machining precision.
- Blades with a hard metal insert for driving on surfaces up to 67 HRC.
- Used together with a Tecnologie FRB rotating live centers for precision grinding, it allows the part to reach much higher rotating speeds than when used with dead centers, thus when used with the correct grinding wheel can lead to reduced cycle times.
