Threading Clamping Systems
THE RUBBER-FLEX-CLUTCH COMPENSATES FOR SYNCHRONISATION ERRORS
To optimise the process when cutting or forming threads with synchronised machine control, the synchro chuck must maintain axial smoothness, especially under torque load!
The patented coupling („Rubber-Flex-Clutch“/RFC) is the core of the FAHRION CENTRO|P synchro clamping system. This innovative technology performs length compensation, drive and damping in a single element.
It eliminates the need for traditional mechanical components. As a result, the FAHRION synchro chuck responds consistently sensitively even under torque load, as no friction from mechanical elements can occur.
1. Synchronisation errors from various sources are compensated for.
2. The tensile and compressive forces on the threading tool are minimised.
3. The dampened reversal of the rotation direction significantly extends tool life.
THREADING CLAMPING SYSTEMS COMPONENTS
What a synchro chuck can do
A thread tapping chuck with minimal length compensation („synchro chuck“) works essentially „against“ the axial tensile and compressive forces that occur during thread cutting or forming. Or rather: It works „with“ them. It compensates for any synchronisation errors and keeps the applied forces under control. To safely produce threads, it is crucial that the synchro chuck maintains its smoothness, especially under torque load. However, when the synchronisation of the rotation and feed axes decreases due to wear, temperature fluctuations, tolerances, mass inertia and other factors, the load causes stress, ultimately reducing the tool’s lifespan and durability.
In general:
The weaker the axial force, …
… the better the quality.
… the lower the wear.
… the longer the tool life.
… the safer the process.
FROM reliable problem-solver in critical processes
The FAHRION CENTRO|P synchro chucks ensure the highest process safety. The torque decoupling via the Rubber-Flex-Clutch (RFC) reduces the risk of tool breakage, especially during torque spikes. With high reproducibility of threads, CENTRO|P synchro ensures consistent production quality, which is especially crucial in industries with tight tolerances. Vibrations are effectively dampened, significantly improving the thread surface quality and minimising scrap risk.

Tool life extended by 30% for M3 threads
Customer
Manufacturer of Machine Spindles

Precision Tools
For a customer (a precision parts manufacturer in the electronics industry), we were tasked with significantly increasing the number of acceptable M3 threads.
We achieved this: Compared to two existing synchro chucks (1180 and 1310 acceptable threads), we increased the number of acceptable threads to over 1700. This corresponds to an increase of more than 30%.
