Aerospace – Disk
The disk in an aircraft engine is a crucial component that supports the turbine and compressor blades. The disk possesses the ability to withstand extreme temperatures and pressures, directly impacting the efficiency and performance of the engine. It requires lightweight, high-strength, and precision machining. Tungaloy’s unique chip breakers and advanced coating technologies enable efficient cutting and extended tool life during the machining of titanium alloys.
Tooling concepts
- Providing solutions for high-efficiency rough machining in titanium.
- Proposing effective tool usage, including machining paths and specialized shape tools (such as dog-bone type grooving inserts).
- Enhancing machining reliability with a new coating that exhibits excellent resistance to thermal cracking and crater wear.
Featured process
Process 1: OD Rough turning
Benefits
- For OD rough machining for the component, round inserts with high edge strength are the first choice.
- Round inserts are also suitable for profiling. By machining to a shape close to the final form during rough machining, the finishing margin is minimized.
- RS chip breaker, designed exclusively for round inserts, ensures stable chip control and extends tool life.
AH8015
- Extremely long tool life for difficult to cut materials
- Good balance for wear and fracture resistance
Process 2: OD Rough turning
Benefits
- Allow high feed rate due to the low approach angle design that reduces chip thickness
- High-cost efficiency due to double sided insert with 10 edges
- The combination of lever lock clamping system and dove tail insert shape allows both smooth chip evacuation and high clamping rigidity
AH8015
- Extremely long tool life for difficult to cut materials
- Good balance for wear and fracture resistance
Process 3: OD Rough turning
Benefits
- Applying grooving tools to profiling turning operations allows for machining with a single tool, achieving tool consolidation and reducing machining time.
- External turning with grooving tools induces a pseudo-small approach angle caused by holder flexure, resembling a high-feed cutting edge. This high-feed cutting edge proves effective in prolonging tool life during titanium alloy machining.
Process 4: OD Finish turning
Benefits
- HRM breaker is a breaker specialized for machining difficult-to-cut materials such as titanium alloys and heat-resistant alloys, achieving stable chip control and extended tool life.
- By using the TungTurn-Jet holder, coolant is supplied near the cutting edge, enhancing the cooling of the cutting edge. This is particularly effective in extending tool life for titanium alloys, which often experience higher cutting temperatures.
AH8005
- Prevents boundary wear which is a problem in heat-resistant alloy turning
- Excellent balance between wear resistance and fracture resistance
