Drilling process

Drilling process

General information

In the industry of metal work tools, shorter processing times are always in high demand. At the same time, the requirements to the manufacturing precision and the process reliability are extremely high. In order to fulfill these requirements, the "machine tool – spindle – tool – tool holder" system need to be considered as a whole (see additional info).

For the use of the CrazyDrill Cool XL and CrazyDrill Pilot, Mikron Tool has defined a fast and reliable procedure which achieves optimal drilling results.

Rapid deep-hole drilling up to 40 x d

  1. Pilot drilling (in one step)
  2. Deep-hole drilling in one step up to 40 x d
    Exception: a deep-hole drilling cycle with chip break and chip removal (pecks) must be used in difficult-to-machine materials such as titanium

Drilling with CrazyDrill Cool XL in one step

1. Pilot drilling up to drilling depth of 2 x d:

2. CrazyDrill Cool XL: 

  • Switch on coolant of CrazyDrill Cool XL
MikronTool-Products-Process-CrazyDrill-Cool-XL-point-2
  • Enter the hole at a speed of maximum n = 500 rpm and vf = 1’000 mm/min (39,37 IPM) without touching the bottom of the hole

  • Increase speed (see cutting data) and wait until the desired drilling speed is reached. Program waiting time in case of slow spindle acceleration rate

  • After the desired drilling depth is reached, return with the drill to drilling depth 2 x d at feed rate or rapid traverse

  • Reduce speed to n = 500 rpm

  • Exit the bore at speed n = 500 rpm and vf = 1’000 mm/min. (39,37 IPM)

Note:

For the drills of 20, 30 and 40 x d the CrazyDrill Cool XL needs to enter the hole and be retracted from the pilot hole at reduced speed. For the CrazyDrill Cool XL 15 x d the afore mentioned procedure is not necessary.

Note:

  • Do not take the drill completely out from the bore between pecks (otherwise risk of resonant vibration).
  • For the drills of 20, 30 and 40 x d the CrazyDrill Cool XL needs to enter the hole and be retracted from the pilot hole at reduced speed. For the CrazyDrill Cool XL 15 x d the afore mentioned procedure is not necessary.
