Machining the turbine blade

Mill scale removal

• Sturdy base body design for high loads
  
• Cutting depth up to 8.4 mm
• 8 usable cutting edges per indexable insert
• Double-sided negative insert with integrated clearance angle for reduced cutting forces and smooth cutting

Rhombus roughing

• High process security → even for unmanned production
• Cutting depth up to 3.5 mm
• 16 cutting edges per indexable insert
• Masterfinish geometry → for outstanding surface quality

Blade roughing

• Larger setting angle than on the regular HFC → higher ap possible
• Combination of HFC and button insert
• Large chip spaces → excellent chip evacuation
• Ideal for blade roughing using any strategy

Blade roughing with ceramics

• Maximum productivity → cutting speed over 10x higher can be
• achieved compared with solid carbide
• Significantly reduced machining time for roughing
• Positive indexable insert for machining using a variety of different milling strategies
  
• SiAlON CTIS710 ceramic grade for milling nickel-based alloys

Blade pre-finishing with carbide button inserts

• Can be used for various roughing strategies
• Stable, soft-cutting indexable insert
  
• Positive installation position of the indexable insert
  - Less cutting pressure
  - Lower cutting forces
  - Unstable components
• Perfect for multiaxial machining
  

Blade finishing

• Cost-effective, unbeatable price-performance ratio
• Patented simple and intelligent Trigon interface
• Closes the gap between indexable insert- and solid carbide milling cutters
• No regrinding logistics required
• Extensive range for further applications 

Blade root & head roughing

• Double-sided negative button insert
• 8 cutting edges per indexable insert
• Simple indexing system
  
• Irregular pitch for smooth cutting
  

Blade root & head finishing

• Extremely positive installation position of the indexable insert → low cutting forces, even in difficult-to-machine materials
• Cutting depth up to 6 mm
• 4- or 8-edged indexable insert for the same insert seat
  
• Irregular pitch for smooth cutting
  

Milling root slot & transitions

• Extensive range for every application
• Reliable and smooth cut thanks to the special cutting edge shape, particularly for plunge milling
  
• Irregular pitch for smooth cutting
  

Milling root slot & transitions

• For machining radii and slots
• Roughing & finishing
• Optimised carbide grades and high-performance coatings for the perfect machining of a wide variety of materials
• Productivity & process security → geometry adapted to your application,   irregular pitch and irregular pitch of the helix
