SPE - 6 CNC Blade Polishing Machine for turbine blades manufacturing
Turbine blade grinding and polishing machine. SPE machine tools are used throughout the world for belt grinding, linishing, finishing, deburring and polishing of fan blades, leading edge sheaths, gas turbine blades, compressor blades, buckets and vanes (OGV and NGV). Also polishing of thermal barrier coating on steam turbine blades. The SPE is the right choice for turbine blades manufacturing. 6 interpolating axis guarantee a perfect positioning of the contact wheel to the airfoil surface of steam and gas turbine blades. 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 SPE is also used for finishing and polishing implants and other complex medical work pieces such as macintosh blades.
Rigid heavy duty machine design for wet belt and wheel grinding and polishing blades for steam and gas turbines. 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/work piece surface. This ensures a reproducible and repeatable material removal.
The SPE is designed with one continuous machine base which allows a fast installation and makes it easy for this machine to be relocated. It is completely enclosed with mist extraction system.
The machine is designed for common machine tool fixturing.
Wet belt 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 SPE process 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 leading and trailing edges
- Perfect solution for turbine blades manufacturing
