ALPHA CNC bowl polishing machine tool

CNC machine tool with 6 axis for belt grinding, polishing and belt linishing aircraft engine airfoils such as fan blades, vanes (OGVs and IGVs), steam turbine blades and gas turbine compressor blades and vanes. Extreme high precision and repeatable stock removal allows balancing of milling process to save milling time and cutter costs by maximizing milling roughness followed by MTS process.

CNC controlled machine for belt grinding and polishing stainless steel weld seams. Belt grinding on the contact wheel or slack belt unit is possible for edge profiling.

CNC polishing of compressor blades and vanes to optimize flow efficiency while at the same time minimizing differences due to tolerances in blade geometry. This is essential to the balancing of the compressor rotor and the fit of the stator parts. The SPE allows to keep up with the demand of this for the latest F-Class & H-Class Gas Turbine Compressors. The SPE CNC-Machine allows automatic polishing of all rows of the Gas Turbine Compressor, as well as most rows of Steam Turbine Blades within tight tolerances and highest repeatability. A dedicated CAD/CAM software allows for generation of NC part programs. As the SPE is a cartesian type machine tool there is no need for referencing or time consuming in process gauging. The precision and repeatability of the process allows the balancing of the milling process to leave a rougher scallop on the blade and save valuable time and cutter on the milling side. Capable of polishing compressor blades, fan blades and vanes up to 550 mm in length.
