The standard Centro P collet chuck system is widely available, with features integral to all Fahrion systems, including the established Fahrion ‘Protect’ coating on the collets. However, features of the Premium programme create new application areas and opportunities.

Fahrion’s UPC range is designed to optimise material removal rates on high-performance machines with high rigidity and drive power. Radial rigidity, compact length and mechanical pull-out protection produce a holding torque of 1,000 Nm.

Very high clamping force usually requires a rigid connection, which in turn results in the creation and propagation of vibration. Micro creeping can also set in earlier. However, if the connection is less rigid but has a higher damping rate, much better results can be achieved. With Centro P Premium UPC chucks, good damping rates are achieved and micro creeping is eliminated through positive locking.

Fahrion’s DPC range is intended for machines with less stability and drive power, but usually with higher spindle and axis speeds. The DPC series is suitable for trimming, finishing and roughing, with all processing tasks able to be performed using the same chuck.

User features include high removal rates on machines with contemporary milling strategies, making DPC chucks suitable for applications in the toolmaking, automotive and general subcontracting industries.

Finally, the MPC range is designed for use with high-speed spindles or for operating in tight spaces.

MPC chucks feature smaller clamping diameters for high spindle speeds and frequently, slim outer contours for deep immersion/pocketing in cavities requiring stable tool clamping.
