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 and mature state-of-the-art milling machines.

Advantages of using a HAMUEL machine for blisk machining:

• Flexibility: the same machine can manufacture either a blade or a complete blisk
• Blisk clamped in a fixed horizontal component axis
• During the process, the blisk performs a purely rotary movement, whereas all pivoting movements are effected by the milling spindle or the tool
• Owing to the basic mechanic design of the machine axes, the tool can access the blisk blades from both sides
• Exploitation of the great technological potential already acquired for the blade processing machine
