MTS - 6 CNC Turbine Blade Polishing Machine
Turbine blade grinding, polishing and finishing machine. MTS machine tools are used throughout the world for turbine blades manufacturing for belt grinding, linishing, finishing, deburring and polishing of fan blades, leading edge inserts, gas turbine blades, compressor blades, buckets and vanes (OGV and NGV).
6 interpolating axis guarantee a perfect positioning of the contact wheel to the airfoil surface. An additional auto-adaptive pneumatic axis ensures constant grinding pressure. This allows the processing of complex blade and airfoil geometries and thus a reduction of milling processes and elimination of manual grinding operations.
. A powerful CAD/CAM software allows for fast and efficient generation of NC programs for any work piece geometry. The MTS is also used for finishing and polishing extrusion screws and crank shafts. IMM is the machinery supplier turbine OEMs trust.
Rigid heavy duty machine design for wet belt grinding and turbine blades manufacturing. 6 CNC interpolating axis plus a floating, individually programmable pressure-controlled axis. The interpolating axis design ensures that the contact wheel and abrasive belt are presented at 90° (perpendicular) to the turbine blade surface during polishing and finishing. This ensures a reproducible and repeatable material removal.
The MTS is designed with one continuous machine base which allows a fast installation and makes it easy for this machine to be relocated if needed. It is completely enclosed, but has an open top design so that overhead crane loading of heavy work pieces, for example steam turbine blades and buckets or rotors and screws is possible.
The machine is designed for common machine tool fixturing.
Wet blet grinding offers many advantages and allows processing of materials such as titanium, chromium-nickel steel, nickel-based alloys and non-ferrous metals.
Benefits of the MTS blade grinding and polishing system include:
- Constant quality of blades
- Impeccable surface quality
- Highly reproducible and repeatable process
- Easy to program by means of off-line software
- Significant savings in a 5-axis milling process through balancing of process.
- Work relief in particular with heavy blades.
- Precise polishing and profiling of the leading and trailing edge.
