Precise and synchronised down to the last corner
The FAHRION-specific design of the guideways ensures maximum concentricity even with long overhangs. The Rubber-Flex-Clutch (RFC) provides the necessary damping properties in the axial and radial directions. Our Mini Synchro Chuck MSC8 only requires a diameter of 10 mm on the clamping nut. A unique feature of the extended CENTRO|P synchro versions is that, despite their extremely slim outer contour, they have an internal coolant supply system.
Additional cost saving:
You only need the Mini Synchro Chuck (MSC) in the desired longer version + cheaper taps in the standard length. Expensive taps in the longer version are no longer necessary.
Many advantages thanks to internal cooling lubricant supply
A sufficient quantity of coolant at the right pressure in the right place is essential for threading. It is therefore usually advantageous if the coolant is channelled through the tool. As shown schematically in the pictures, an internal cooling lubricant supply ensures that there is always enough cooling lubricant directly at the cutting edge, even with critical contours. The outlet can either be through the tool and/or through the collet.
Thanks to the internal supply of cooling lubricant, there is always sufficient cooling lubricant directly at the cutting edge, even with critical contours.

FAHRION CENTRO|P synchro
rigid chuck
A synchro chuck compensates for any synchronisation errors and reduces axial forces. This leads to better quality, lower wear, a longer tool life and a safer process.
In order to produce threads reliably, it is crucial that the synchro chuck (tapping chuck with minimum length compensation) can maintain its ease of movement, especially under torque load. The axial forces generated during thread machining can be clearly seen in the diagram: Machining with a rigid chuck (orange line) compared with a chuck including synchronised compensation (blue line).

The diagram shows 4 chucks with different mechanical synchronised balancers, which we have compared with our RFC technology.
Compared to other competitors, our tapping chuck exhibits the lowest wear-promoting axial forces (dark blue line).
Every mechanical engineer knows: “When turning and pulling at the same time, you get a jam.” This is an ongoing basic problem caused by balls, pins or similar drivers under torque load. FAHRION technology simply dispenses with such mechanical positive-locking drivers and instead works with our patent-pending clutch (“Rubber-Flex-Clutch”). The “Rubber-Flex-Clutch” (RFC) allows the tool holder to absorb torque loads without mechanical positive locking. The process of driving and equalisation takes place “in one piece” and is almost frictionless. In addition, the RFC ensures a damped momentum when the direction of rotation is reversed.
From synchronised compensation in four directions to backlash-free synchronised compensation
Pull and torsional force during thread cutting or forming
The RFC acts on the radial drive in the direction of rotation as well as on the axial compensation in both the tensile and compressive directions.
Push and torsional force after reversing the direction of rotation
The RFC acts on the radial drive in the reverse direction of rotation as well as on the axial compensation in both the tensile and compressive directions.
CENTRO|P synchro chucks are characterised by particularly long and precise guidance of the shaft with consistently high FAHRION quality.
