Gas Turbine Engine
Description
The Korean aircraft turbine manufacturer was looking for a cost-efficient, yet reliable solution for the application of back spot facings on the casing of their gas turbines.
Application details
Application details
- Main bore: Ø7.0 mm
- Spot facing / Counterbore: Ø15.0 mm
- Ratio Ø-main bore to Ø-spot facing = 2.14
- Depth: 4.5 mm
- Working length: 5.3 mm
- Material: M152
- Machine: STARRAG 5-axis
Proposed solution
Proposed solution
HEULE recommends its Back Spot Facing tool BSF-A-0700/040-7.5. BSF brings together a simple working principle together with a high reliability. The BSF tool counterbore diameters of up to 2.3 times the bore diameter.
Machining parameters:
- Cutting data:
Speed Vc = 10m/min. = 212 rev/min.
Feed F = 0.02 mm/rev. - Activation speed:
S = 15.0 : 7.0 = 2,14
2.14 > 1.8 = Minimum 2000 rev/min.
