Turbine blade grinding machine mBTG-DANTIP

for rotorshorizontalCNC

Product overview
These machines grind, deburr and measure blade tips of assembled aero engine and APU rotors while rotating at speeds up to 7000 rpm. The mBTG-DANTIP platform supports multiple rotor sizes and configurations and can be supplied as a standalone cell or integrated with vertical grinders for match machining of rotors and compressor casings.

Highlights

• Over 35 years of partnership with jet engine OEMs and major MROs
• Optimised, rigid, dynamic and thermally stable mechanical design
• Spindle with an average service life exceeding 10 years
• Can be delivered as part of a cell with vertical grinders for match machining
• Global specialist support team for blade-tip grinding

Technology

• Air-conditioned enclosure for thermal stability and process accuracy
• Robust pedestals and dual angular-contact bearings per spindle for high stiffness
• dBTM in-process measuring system: OEM-approved, in-house laser-based measurement
• High-speed laser for real-time measurement and automatic in-process control
• DANTIP conversational programming with canned cycles to minimise operator influence
