 Centerdrill CNC-Daten

When working with a NC- or CNC-controlled equipment there is the possibility to significantly accelerate the execution of the production process. Depending of the machine design the feed rate as shown in the example - may be increased by increments during the individual process steps.

* With flat designs the work lengths increases by the height of the collar.

** Please check the length of the working part L1 of every new Centerdrill tool, because of our manufacturing tolerances.

Depending on the application and machine conditions the process speeds may also clearly vary from
the above information. Our application technicians are pleased to consult you.

Time saving:

Example: Centerdrill 7.3 long for M8 + Centertap M8 in 2mm steel (S235JR). For approx.. 8000 threads (for your calculation [note: it depends on your process parameter and your applications]).

With Centerdrill + Centertap you will need only approx. 6 sec. for both operations together.

The advantage may be projected approx. about 40% time saving compared to other technologies, like welding- or rivet nuts.

Material cost savings:

Example: Centerdrill 7.3 long for M8 + Centertap M8 in 2mm steel (S235JR). For approx. 8000 threads (for your calculation [note: it depends on your process parameter and your applications]).

Do you know your material costs of press nuts, welding nuts or rivet nuts? Depending on the type it
will cost you between 0,06 and 0,16 EUR/pcs.?

With Centerdrill + Centertap your costs per thread will decrease. The costs are only approx. 0,0134
EUR per thread. This saving represents a material cost advantage of approx. 20% up to 90%.
