Collet chuck centerdrill

To achieve best results with centerdrill we recommend the following basic equipment:

1x collet chuck with cooling ring, clamping nut and spanners.

1x centerdrill collet, optional Ø 6, Ø 8, ..., Ø 20mm

1x 250 gr. parting paste for flow punch forming

1x 0,5 l lubricant for thread forming

Due to the extreme thermal fluctuation and the radial load, proper clamping of the workpart and the flow punch former is critical. The warmth generated during the process must not be allowed to enter the spindle but instead must be deflected or cooled. Customary three-part chucks can cause breakage of the flow punch former if it is not clamped centrally!

For this reason a collet chuck with cooling ring was developed especially for flow punch forming with centerdrill, with which the heat can be dissipated ideally and a secure clamping can be ensured. For optimal concentricity and secure clamping, a special collet is used to locate the centerdrill.

Parting Paste
Moistening the centerdrill with our highly heat-resistant parting paste, matched to the respective material to be processed, is important for the service life of the centerdrill. The paste can be applied manually or with a spray device.

Lubrication during thread forming
The use of our lubricant is highly recommended during thread forming. It should be applied before each operation on the center- tap. Our lubricant is ecologically tested according to DIN.
