Center points

Outer tips in various designs

Hollow tips in different designs

Special tips according to customer requirements

Segmented tip

Maximum precision thanks to diamond

  • all sizes, geometries and special shapes can be realized
  • high PCD quality = low friction and long service life
  • high accuracies: Roundness of less than 0.5 µm (hollow tips)
  • repair and regrinding possible
  • individual design and service by DR. KAISER

High-precision machining of complex, rotationally symmetrical components is often carried out by clamping between tips. Revolving conical tips are not suitable for maximum precision of less than 1 μm due to the bearing dynamics. In high-precision machining applications, therefore, only fixed tips are used. Here, the process forces are transferred directly to the tips – generally made of carbide – via the work piece. In many applications, the contact chamfers are only a few tenths of a millimetre, meaning that large surface pressures lead to high friction and a fast wear rate.

Maximum accuracies, especially in continuous operation, can only be achieved economically with PCD tips:
the low friction compared to steel benefits the process behavior and improves the shape, position and roundness of the work pieces.
Small hollow points up to 36 mm in diameter are manufactured from solid PCD. Beyond that, hollow points are manufactured segmented.

Outer tips

For workpieces with large diameters
flexible and precise: The center hole in the component enables accurate re-chucking and machining beyond the end areas. The low friction value between diamond and steel means that very high levels of accurancy can be achieved on the component.

Hollow tips

Indispensable for long components such as jet needles: The high-precision hollow tip with roundnesses of < 0.5 μm on the PCD internal tapered surface. Components with bevelled ends can therefore be machined around the perimeter with high precision.

Special tips

Long, slim, multi-recessed components or the machining of end contours (e.g. jet needle): Special solutions for the highest demands are DR. KAISER’s speciality, in a PCD or carbide version.
