Our dedicated polishing machine tools feature an auto-adaptive technology for polishing, linishing and grinding the most complex blades, work piece geometries and shapes. Our 6 CNC axis MTS and SPE machine tool series are standard high precision machine tools which provide a robust platform with the blades located within a fixed coordinate system, therefore providing a consistent position of the tool relative to the component. Without the need of any in process calibration or referencing, our MTS and SPE machines are known for their outstanding repeatability and reproducibility. The SPE and MTS machine tools are used throughout the world for belt grinding, linishing, deburring and polishing of fan blades, leading edge inserts, gas turbine blades, compressor blades and vanes (OGV and NGV). Our SPE can also be configured with tool units for belt polishing, brushing untits and high speed spindles for deburring operations and processes. A powerful CAD/CAM software allows for fast and efficient generation of NC programs for any blade geometry. Special solutions machinery from IMM for the aerospace industry includes Engine Inlet Lip Skins polishing machines with 14 CNC axis for lip skins with a diameter of up to 4 meters (157 inches).
