Turbine disc

These complex turned parts in hard to machine alloys such as Inconel 718, Waspalloy and Udimet 720 generally feature profiled pockets with various difficult clearance requirements.

A complete package of standard tools together with uniquely productive solutions is readily available to deliver stable machining to any turbine disc feature.

 

​The modular SL70 tooling system

Due to tough material, accessibility and productivity, round inserts offer the best method and are used in both roughing and finishing.

  • CoroTurn SL70 blades designed to fit the typical profiling and pocketing features
  • Oval coupling offers excellent stability and accessibility
  • All radial and axial clearance requirements covered in a compact program
  • Multi-task and vertical turning lathe requirements met with Coromant Capto size C5, C6 and C8 
  • Carbide RCMT and CoroCut grades have high pressure coolant as standard

​Optimized programming and optimized tools give optimized results

By choosing trochoidal turning for the roughing operation over the more traditional ramping method, productivity can be doubled with improved security and tool life.

  • Grade CC6060 allows for larger depths of cut to be taken
  • Reduced number of passes required using trochoidal turning
  • Green-light production – secured, controlled, predictable wear

Pocket dia 500mm (19.685 inch)

​Scallop milling

Our exchangeable-head system with CoroMill® 316 is the economical tool for scallop milling. With a shorter cutting length than other tools, it provides essential stability, optimized for these small depths of cut with close tolerances.

Tool change and tool setting times are drastically reduced compared to traditional end mills and chucks. Chamfering inserts are also available in the same system.
