PO 900 BF

Blisk Machining on a PO 900 BF

EMAG ECM has two machine types for the different machining tasks of jet engine and turbine production: while the small PO 100 SF model is designed for machining turbine blades, the larger PO 900 B machines complete blisks. The systems differ in machining area size, footprints, generator capacity and the number of machining axes. Precise PECM technology and EMAG high performance components are naturally available in both types.

Both these machines also provide the user with key EMAG innovations such as a Mineralit® polymer concrete machine base, intelligent software and hardware interfaces and efficient automation solutions.

Machining from single Turbine Blades to the Complete Blisk

PECM - Non-contact material removal and fast processes.

Electro-chemical machining is a well established process for machining extremely hard materials. With their PECM technology, the experts from EMAG ECM have further developed this method and tuned it to perfection. During the process, the workpiece becomes the positive anode and the tool the negative cathode as an electrolyte solution flows between them.

In the PECM process the gap between the workpiece and tool, through which the electrolyte solution flows, is particularly narrow. The supply of the electrolyte solution is enhanced by a mechanical oscillation motion. Both these factors together ensure that the material removal is even more effective and precise.
