Key Design Features

Features
  • THE COLLET SITS COMPLETELY INSIDE THE CONE
    → The longer guide means {500}greater accuracy and stability
  • PRECISELY GROUND DUAL GUIDE FOR THE COLLET NUT
    → While the rear guide centres the clamping nut, the front guide generates an optimal force transfer between the three components when tightening the clamping nut
  • A STABLE TRAPEZOIDAL THREAD FOR TRANSFERRING OF THE CLAMPING FORCE
    → As a classic lead screw, the trapezoidal thread achieves a higher resulting clamping force with the same tightening torque
  • A CHUCK BODY WITH CONTINUOUS MAXIMUM DIAMETER
    → Maximum stability without increasing the interference contour

Power Chuck Body UPC (Ultra Power Chuck) / HDC (Heavy Duty Chuck)

A power chuck with an ER collet – is that even possible?

The power chucks UPC ↗︎/HDC are extremely rigid high-performance chucks designed for the most demanding tasks, primarily with radial loads. The wall thickness of the chuck body was increased in order to take more radial force and to suppress the vibrations as best as possible. The uniquely designed trapezoidal fine thread allows the collet nut to be tightened more efficiently. As a result, even higher clamping forces are generated. 
Together with other specific system components such as a ball-bearing collet nut and a form-fitting wedge collet, the UPC ↗︎/HDC chuck becomes a superior power chuck using ER collet technology.

Cylindrical tool extensions

Cylindrical tool extensions ↗︎ are particularly suitable for precise machining in hard-to-reach areas and set new standards in concentricity, setup time and flexibility.
Instead of purchasing expensive custom tools, you can quickly and easily create various lengths for tool holders from existing components. With the CENTRO|P system, a seamless range of lengths from 160 mm to 460 mm is possible.

Collet chuck with ad­just­able runout accuracy

In order to achieve optimal machining results, e.g. during reaming, or also for other ultrafine machining, a perfect concentricity of the tool is essential. Alignment chucks are used to eliminate concentricity errors between the tool holder and the machine spindle.
The adjustable high-precision chucks offer all the advantages of the CENTRO|P clamping system and additionally allow concentricity to be precisely adjusted via four adjustment screws on the circumference of the chuck.

For optimal concentricity, these adjustment chucks must be set directly in the machine spindle.
This is the only way to completely eliminate any concentricity deviations of the chuck and machine spindle as well as faulty interface errors.

AFC (Adjustable Finishing Chuck) ↗︎

Largest Possible Tool Passage

The CENTRO|P is designed to offer the largest possible tool passage and therefore provides an extra-long length adjustment range. This allows the tool to be clamped at the optimal overhang length, preventing vibrations, protecting the tool and optimising the surface finish.

Benefits

Versatility

For every spindle interface, the right chuck.

Wide range

Combines different geometries with multiple lengths.

Patented ER Clamping

The collet is fully seated in the cone and is optimally fixed by the dual guide and trapezoidal thread.

Cost-effective

Saves investment in expensive hydraulic and shrink-fit technologies.

Maintenance-Free

Neither media nor temperature is used to generate clamping force.

Long-Lasting

Due to the purely mechanical clamping technology, there are no leaks or temperature-induced material changes.

Constant clamping force

As the taper compensates for axial tolerances, the clamping force is independent of bore-to-shaft tolerance discrepancies.

Additional CENTRO|P Advantages

High concentricity and repeat accuracy
With FAHRION precision collets GERC-HP, a system accuracy of 3 μm (at 3 x D, max. 50 mm) is achieved. Conclusion: You work up to six times more precisely than with conventional ER collet chucks.
Highest Balancing Quality
The chuck is a crucial element in the system comprising machine spindle, tool holder and tool and plays a key role in preventing vibrations. For this reason, great importance is placed on the balancing quality of the CENTRO|P precision collet chucks. They are finely balanced as standard for speeds up to 60,000 rpm, thus achieving the highest dimensional accuracy, surface quality and tool life.
Enormous Stability
With the special design of CENTRO|P, a better and more even distribution of clamping forces across the entire cylindrical surface of the tool shank is achieved and radial forces are optimally absorbed. As a result, perfect surfaces are produced when milling.
High Rigidity
An optimised outer contour counters bending and compressive forces. This principle was practically implemented in the design of CENTRO|P according to the latest insights. The chuck body is reinforced to match the diameter of the collet nut, providing maximum rigidity and an optimal interference contour.

Many benefits with FAHRION|Protect

FAHRION|Protect goes beyond all the standards you know for corrosion protection of clamping tools. Many clamping tools are not protected at all. Others limit corrosion protection to a purely „cosmetic“ focus on visible surfaces. FAHRION is the first manufacturer to offer a coating of the entire chuck body, including the functional surfaces, in the µm range – and that across its entire, wide product range. FAHRION|Protect effectively protects FAHRION collet chucks from external influences, maintaining their functionality and precision for longer. Once again, FAHRION demonstrates how the latest technology can be brought to market as a practical customer solution in an impressive way.

Benefits

Long-lasting precision

  • The target geometry between the collet and the taper seat in the chuck remains intact for a long time, ensuring a consistently flat contact without corrosion-related irregularities.
  • Parts in production remain within the specified tolerances for a longer period. The number of defective parts decreases.
  • This ensures production processes remain at a high level for longer, saving time and guaranteeing tight delivery deadlines.
Longer tool life
  • Better concentricity extends tool life. This saves costs through fewer setups.
Longer Service Life for Collet Chuck Bodies
  • Collet chuck bodies need to be replaced less frequently and can be used for longer for precision applications.
Longer machine spindle life
  • Reduced tool imbalance permanently relieves the machine spindle, lowering maintenance costs.
