CrazyMill Cool Ball
Roughing and finishing cutter
with through-tool cooling,
from 0.3 mm (.0118")

Shorter machining time* -
up to 2 times faster

  • Extremely high metal removal rates (Q) can be obtained thanks to the high tool performance (ap up to 1 x d) and high cutting speeds (vc up to 280 m/min (919 SFM))
  • Up to 2 times higher efficiency than with commercially available tools

*The comparison takes into consideration the milling tools and milling methods available on the market as well as the machining parameters recommended by manufacturers.

Long tool life* -
up to 4 times longer

  • Through-tool cooling: no heating of cutting edges, chips flushed away
  • Large cooling channels compared to the milling tool's diameter: hence extremely efficient and high volume flow of cooling lubricant; the friction-generated heat is mostly absorbed and discharged by the cutting oil
  • High-performance coating eXedur RIP:
    • High-temperature and oxidation-resistant
    • High degree of wear resistance
    • Low adhesion to metals prevents bonding
    • No deposition of chips due to low friction coefficient
  • The life of the CrazyMill Cool Ball is up to four times longer in comparison to commercially available milling tools

*The comparison takes into consideration the milling tools and milling methods available on the market as well as the machining parameters recommended by manufacturers.

Higher process reliability* -
higher productivity

  • No overheating of cutting edges or of the tungsten carbide due to through-tool cooling
  • No overheating of the high-performance coating due to efficient and high volume cooling
  • Through-tool cooling prevents material buildup on cutting edges and does not allow heat to build up on the cutting edges

*The comparison takes into consideration the milling tools and milling methods available on the market as well as the machining parameters recommended by manufacturers.

High degree of precision / high surface quality

  • Perfect surface finishing quality thanks to the special geometry and targeted flushing of the chips by means of through-shaft cooling
  • 2 – 4 times better Rz values compared to conventional milling tools

Lower production costs* - 
lower machining costs

  • Shorter machining time: up to 2 times faster
  • Excellent tool life: up to 4 times longer

*The comparison takes into consideration the milling tools and milling methods available on the market as well as the machining parameters recommended by manufacturers.

 

The milling program 

  • Ball mill for contour, copy and wall milling
  • Applied for roughing and finishing
  • Standard milling sizes: 0.3 mm – 8.0 mm (.0118” - .315”)
  • Three versions: type A (maximum machining depth 2 x d), type B (maximum machining depth 3 x d), type C (maximum machining depth
    5 x d)
  • The cutting length for all end mill cutters is 2 x d
  • Milling tools with 3 mm (.118”) shaft, 4 mm (.157”) shaft, 6 mm (.236”) shaft, 10 mm (.394”) shaft, 12 mm (.472”) shaft

Special characteristics

  • Through-shaft cooling channels: regular and substantial cooling and targeted flushing of chips
  • Unique and patented - new horizons in milling
  • HSPC (high-speed performance cutting) in all metals (such as all unhardened steel grades, aluminum, nonferrous metals), especially suitable for difficult-to-machine materials (such as stainless and acid- and heat-resistant steels, titanium and super alloys)
  • Surface factor 2 - 4 times better than the competition
  • Performance up to 2 times greater than all other commercially available products
  • Longer life: up to 4 times longer in comparison to all other commercially available products
  • Tungsten carbide with high fracture toughness and thermal shock resistance
  • Wear-resistant and heat-resistant high-performance coating eXedur RIP
  • Roughing and finishing operation in one work cycle
  • Mikron Tool produces all tools with highest repeat precision. Hence the user will benefit from long term stable production conditions (stable process and machining precision)
