CNC-Programming (Data examples)

For working with 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.

 

Examples for M6 and M8, 2 mm S235JR (ST37-2):

 

centerdrill core hole-Ø (mm)	max. wall thickness (mm)	RPM* (mm)	tool length L1 (mm)	working path** (mm)	work steps	feed rate (mm/min)
M6 - Ø 5.4 long (long-flat)	2.7 (3.0)	2400	13.5	12.0 (13.5)	0 - 2 2 - 4 4 - 6 6 - 11 11 - end	150 250 350 550 200 (900)
M8 - Ø 7.3 long (long-flat)	3.5 (4.5)	2100	18.1	16.6 (18.1)	0 - 2 2 - 4 4 - 7 7 - 14 14 - end	150 250 350 550 200 (900)

 

All other CNC data can be supplied on request.

 

* Spindle RPM +/- 10%, depending on the quality of the material and wall thickness
** With flat designs the work lengths increases by the height of the collar.
