mBTG-DANTIP - Cylindrical grinding machine

The 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.

It has been shown that diametric tolerances can be held to 0.025 mm. This achievement is regarded as very important because the clearance between the rotor blade tips and the outer housing has a critical bearing on the engine´s performance.

mBTG is typically used to grind and measure rotors such as CT7/T700, RTM322, CFM56, CF34, V2500, TP400, F404 and J85, among others and DANTIP is used for large engine rotors.

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. The rotor blade tip grinder and the stator case turning/grinding machines interchange “data” to obtain dimensionally perfectly matched rotors and casings, thus optimising engine core performance and efficiency.
