mBTG-DANTIP - Blade tip grinding and measuring machine for aerospace industry
mBTG-DANTIP: High-speed blade tip grinder
The DANOBAT mBTG and DANTIP machine series are for precision grinding, deburring and measuring the blade tips of finish assembled engine turbine and APUs rotors.
These machines, designed and developed by Danobat grind the blade tips of the rotor while they are being spun at high speed, (up to 7000 rpm) thereby presenting the blades to the grinding wheel under the appropriate operating conditions.
This feature ensures the highest degree of accuracy that can be obtained with current technologies on blade tip grinding.
External cylindrical grinding
Advantages
- mBTG is typically used to grind and measure rotors such as CT7/T700, RTM322, CFM56, CF34, V2500, TP400, F404, J85 and LEAPX among others and DANTIP is used for large engine rotors.
- The machine structure of mBTG machine is made in natural granite and cast iron whereas DANTIP bed structure is made in cast iron
- Movement of main machine linear axes is achieved by means of a linear motor on mBTG whereas it is via a high precision recirculating ballscrew and nut assembly with direct drive from a servomotor on DANTIP machines
- The complete working environment is temperature controlled
- In-process gauging key for real time control of the grinding process to ensure optimized radius of blades for the best engine efficiency
- The measuring system hardware combines the highest speeds with outstanding sensitivity
- These machines can be supplied forming “Match Machining Cells” with DANOBAT VG vertical grinders as a complete solution for match machining and measuring the rotors and casings of the same engine.
