Precise and fast machining of turbine blades
July 22, 2010
However, these materials are very expensive; their processing is extremely demanding. In fact, just a minimum defect on the surface of the blades of turbines to reduce performance, increase maintenance costs and compromising the useful life of the turbine. Because of the high costs of material and the time required for machining, manufacturers cannot afford produce defective parts. The reliability of the process is, therefore, the critical parameter in the manufacture of blades of turbines.
Given that the accuracy is extremely important in these processes, Ceratizit has developed the MaxiMill 274, a specific Strawberry for reliable and precise machining of the foot of the blades of turbines. The plates of the MaxiMill 274 Strawberry have eight cutting edges particularly suitable for ultra-resistentes materials, whereas the very reduced cutting efforts ensure the realization of smooth surface qualities in the components and the respect of narrow tolerances.
"With MaxiMill 274 we can provide manufacturers a tool that meets the specific requirements imposed by the machining of turbine blades." "Respect for close tolerances and the obtaining of surfaces already have no any problem, even for difficult machining materials", explains Markus Krabichler, head of product of the segment mechanical engineering and transportation.
The new Ceratizit Strawberry is characterized by a low power required and ensures a very quiet machining. The angle of 25 ° allows a favourable mounting of the insert in the tool position. Easy handling and good accessibility with screwdriver ensures preparation and adjustment times lower. Lubrication holes ensure a sufficient cooling allowing maximum progress. MaxiMill 274 then offers all the requirements for an economic and precise machining of turbine blades.
