Innovative tool clamping systems.

When it comes to clamping cutting tools, collet technology cannot be beaten in terms of precision and force in relation to reliability and cost-effectiveness.

CENTRO|P Precision Collet Chucks provide this technology with decisive impulses for decades.

Holders

CENTRO|P revolutionises collet chuck and collet clamping technology, putting it ahead of the competition with respect to precision, clamping force, flexibility and price-performance.

  • Precision - 3µm System Accuracy
  • Clamping Force - Higher holding torque upto 300 Nm
  • Flexibility - Universally usable for drilling, reaming, milling, for HPC/HSC and for tapping.
  • Price Performance - Vibration dampening, increase in tool life, increase in machine spindle life.

Technology

Accurate
Contstant system accuracy with FAHRION GER-HP collets ≤ 3µm
With GER-B collets, system accuracy is ≤ 6µm

Vibration
Vibrations are absorbed by the collets.

Powerful
The unique design of FAHRION HPC clamping nut with trapeziodal thread and double-length guide CENTRO|P is powerful and ideal for high performance cutting

Collets

Precise
FAHRION collets DIN6499/ISO15488-B(ER/ESX) set the standards of concentricity and repeatability.

  • GER11-B upto GER40-B 5µm
  • GER11-HP upto GER40-HP 2µm
  • GER-HPD sealed collets 2µm and 5µm
  • GER-HPDD High Precision Coolant Collets with Jet Hole 2µm
  • GER-GBD Tapping Collets 10µm

Rigid
Collets are with 12 slots compared to 16 slots leading to less tendency to distort.




For over 40 years, Schüssler has been synonymous with realising new ideas and inventiveness with a love of precision. This explains why we are constantly investing - to ensure our machinery remains at the forefront of technological development in offering high-precision tool holders.

Product Range

Collet chucks, ER and ER "Mini"

  • Shrink fit holder
  • End mill holder weldon
  • Tool holders with coolant for "Cool Tool" tool
  • Shell mill holders, and many more
All tool holders are available in all standard taper shanks, such as:
  • HSK-40/50/63/100 Form A and E
  • SK 40 and 50 DIN 69871 Form ADB
  • MAS BT 30 / 40
All types of tool holders are available in various lengths as a standard

Quality

  1. PERFECT POSITIONING OF THE CONE IN THE SPINDLE:
    The drive slots on the HSK-taper are hard reworked during machining with taper grinding, thus guaranteeing a 100 % symmetry of the HSK-slots. As a result, we get a perfect seat and torque transfer in the spindle.
  2. HARD REWORKED HSK CLAMPING SHOULDER
    • perfect runout of clamping shoulder (max. 0.01 instead of up to 0.04 according to DIN)
    • highest runout accuracy
    • maximum clamping force
    • maximum radial rigidity
  3. ALL HOLDERS ARE FINE BALANCED (to G2.5, 25,000 MIN -1)
    • smooth and bearing protecting spindle run
    • longer spindle life cycle
    • maximum tool life
    • better milling quality

Runout tolerance of the different tool holder types:

Tool Holder Type Runout A < 160 Runout A >= 160
Endmill holder Weldon, Collet chuck, Schrumpffutter, Whistle Notch-Aufnahmen Shrink fit holder, End mill holder Whistle Notch <= 3µm <= 4µm
Shell mill holder, Combi shell mill holder <= 6µm <= 6µm
Morse taper adapter <= 8µm
