SPE

Machine Characteristic

• 6 CNC axis and a floating, hydraulic axis enable the grinding and polishing of complex and modern airfoil designs
• The interpolating axis design ensures that the contact wheel and abrasive belt are presented at 90° (perpendicular) to the blade surface and thus ensure a reproduceable and repeatable material removal 
• Siemens Sinumeric One controller with integrated operator panel 
• Solid continuous one-piece machine base
• Machine completely enclosed by durable cabinet 
• Electrical cabinet built onto machine base extension 
• Robust belt drive for common abrasive belts with integrated floating axis
• "Pick & Place" machine design for fast installations and minimum floor space requirements
• Separate gravity belt filter unit for coolant filtration 
• Common machine tool fixturing can be used
• The blades are clamped by the root and do not require further support by means of a tailstock
• Wet belt grinding process with conventional organic or synthetic coolant additives 

Application 

• Wet belt grinding, polishing and linishing of blades in chromium-nickel steel, titanium, nickel-based alloys, titanium alloys and non-ferrous metals.
• Forged, milled, super plastic formed and cast blades for the energy and aerospace industries. 

Customer Benefits 

• Rapid return of investment
• Constant quality of blades
• Impeccable surface quality of blades
• Highly repeatable and reproducible process
• Easy to program through offline software
• Proven technology at OEM’s worldwide
• Significant savings in a 5-axis milling process through increased milling roughness before SPE processing
• Work relief – in particular with heavy blades
• Easy to operate – even by CNC inexperienced staff
• Grinding of leading and trailing edges in radial or longitudinal direction possible. 

Software 

CAD/CAM package

• Flexible and fast CNC program creation through innovative interface and CAD/CAM software solution. 
• Creation of NC program from 3D model.

Optional Adaptive Module

• Allows the collection of measuring data from existing measuring sources to create adaptive programs.
