Precise and synchronous 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 is that the extended CENTRO|P synchro versions have an internal cooling lubricant supply despite their extremely slim outer contour.
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, with sufficient pressure in the right place, is essential when threading. It is therefore usually advantageous if the coolant is fed 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 chuck.
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 synchronous errors and reduces axial forces. This leads to better quality, less abrasion, a longer service 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 forces generated during thread machining can be clearly seen in the diagram: Machining with a rigid chuck (orange line) in comparison with a chuck including synchronous compensation (blue line).

The diagram below shows 4 chucks with different mechanical synchronizers, which we compared with our RFC technology.
Compared to other competitors, our tapping chuck has the lowest wear-promoting forces (dark blue line).
Every mechanical engineer knows: “When turning and pulling at the same time it’s stuck.” An existing 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”). Thanks to the „ rubber-flex-clutch” (RFC), the tool holder can absorb torque loads without mechanical positive locking. The process of driving and balancing 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 synchronous balancing in four directions to backlash-free synchronous balancing
Tensile 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 tension and compression.
Compressive 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 tension and compression directions.
CENTRO|P synchro chucks are characterized by particularly long and precise shaft guidance with consistently high FAHRION quality.
