Innovative machining of blisks
Innovative machining of blisks
The document discusses the innovative machining of blisks, which are integral components in turbine manufacturing, particularly in aircraft engines. The focus is on reducing weight and increasing efficiency through advanced materials and integrated component designs.
Technological Advancements
Blisks, a combination of blades and disks, are manufactured using CNC milling machines. This process involves lateral milling of blade profiles from a forged disk, which is clamped and rotated during machining. The use of blisks eliminates the need for joining blade feet to disks, enhancing turbine efficiency and component longevity.
Technical Specifications
The document provides detailed technical data on the machinery used for blisk manufacturing, including:
- Travelling speeds: Linear axes at 65 m/min, B-axis at 100 min-1
- Acceleration: Linear axes at 1 g, B-axis at 15 s-2
- Component spindle interface: HSK-B 160 with a torque of 1,530 Nm and speed of 180 min-1
- Tool data: HSK-A 63 interface, max tool diameter of 80 mm, length of 250 mm, and weight of 6 kg
HAMUEL's Advantages

Flexible machinery Your component Turbine construction Competence Engine construction Gas turbines Experience Aircraft construction Power Most modern technology In particular where the production of aircraft engines is concerned, the demand to reduce consumption acts as the driving power for innovation. This demand can exclusively be met by a reduction in weight along with an increase in efficiency. This situation has provoked the use of highly developed, light-weight, heatresistant materials and the combination of individual components, consequently a reduction of fits and joints. Owing to higher...

Sophisticated manufacturing processes Benefits Efficiency as an argument Today, turbine manufacturing simply cannot be imagined without blisks. They have largely taken the place of individual blades mounted on disks. The word blisk combines the terms blade and disk. Manufacturing a blisk means the lateral milling of blade profiles from a forged disk using a CNC-milling machine. This disk is clamped to the A-axis and can be rotated while being machined by the 5-axes milling head. Here, pivoting is exclusively done by the milling head. The intricate geometry of such a blisk requires a lot of know-how...
