CrazyMill Cool SF/
Superfinishing with highest surface quality and geometric precision

Reduced machining time

  • Thanks to high cutting speed and feed 
  • Decreased finishing operations - polishing and/or tumbling can be avoided or significantly minimized

Long tool life

  • Excellent cutting-edge conditioning
  • Through-tool cooling prevents overheating of cutting edges and guarantees best chip evacuation
  • Large cooling channels compared to the milling tool’s diameter: 
    • Extremely efficient and high-volume flow of cooling lubricant removes chips from machining area: no cutting-edge break outs.
    • The friction-generated heat is mostly absorbed and absorbed by the cutting oil: no material buildup on the cutting edges
  • High-performance coating eXedur SNP: 
    • 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 
  • Long tool life while maintaining a very low roughness

High process reliability and productivity

  • No overheating of cutting edges, i.e. of the tungsten carbide due to through-tool cooling 
  • No overheating of the high-performance coating due to efficient, high-volume cooling 
  • Through-tool cooling prevents material buildup on cutting edges and does not allow heat to build up on the cutting edges 
  • Use of High Efficiency Milling (HEM), even in materials that are difficult to machine 

Highest precision and surface quality

  • Highest surface quality - Ra <0.3 µm
  • Low radial cutting force - guarantees geometrically perfect workpieces
  • Low cutting force - perfect for side milling of thin-walled workpieces
  • Advanced cutting-edge conditioning - very long tool life

 

 

Lower production costs* - lower machining costs*

  • Reduced machining time due to high cutting speed and feed rate 
  • Excellent tool life, at the same time, a very low roughness is maintained
  • A finishing operation (polishing and tumbling) is eliminated or can be reduced

*: 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

  • Superfinishing endmill with five (up to Ø 2.5 mm) i.e. six flutes (from Ø 3.00 mm) and through-tool cooling 
  • Diameter range: 1.0 mm – 8.0 mm (.039” – .315”, fractional inches available)
  • Two versions with variable helix angle and unequal angular teeth division: 
    • Type M (max. milling depth 3 x d) with cutting length 3 x d
    • Type N (max. milling depth 4 x d) with cutting length 4 x d 
  • Milling cutters with 4 mm (.158”) shank / 6 mm (.236“) shank / 8 mm (.315“) shank / 10 mm (.394“) shank / 12 mm (.472“) shank

Special characteristics

  • Excellent surface quality achieving grinding results: Ra 0.3 µm or better, in difficult-to-machine materials
  • Through-shaft cooling channels: regular and substantial cooling and targeted flushing of chips
  • Variable helix angle and unequal angular teeth division, perfect cutting-edge conditioning 
  • High Efficiency Milling (HEM) even in difficult-to-machine materials such as stainless steel, titanium and titanium alloys, superalloys
  • Cutting edge conditioning à guarantees an excellent surface quality and long tool life
  • Low cutting force: outstanding superfinishing milling cutter for side milling of thin-walled workpieces  
  • Low radial cutting force for geometrically perfect workpieces  
  • Finishing operations as polishing and/or tumbling can be avoided or, at least, reduced 
  • New tungsten carbide generation with high fracture toughness and thermal shock resistance
  • Wear- and heat-resistant high-performance coating eXedur SNP
  • 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)
