DANUNIHigh precision grinding machine for aerospace landing gears
External cylindrical grinding
Designed for precision external and internal grinding of different aircraft landing gear struts, such as complexly shaped pistons in internal diameters and external diameters in cylinders.
The Danobat machine revolutionizes the landing gear struts grinding process because it can swing the whole component between centers. With DANUNI range customers can obtain a reduction of up to 50% in machining overhaul times due to the integration of OD and ID operations in one machine.
Different size, models and configurations of machines are available depending on the application and customer requirements. Landing gear components requiring a swing of up to 160" can be handled. In addition, the machine can grind internal bores up to 100" in length
Advantages
- The machine structure is made in stabilized pearlitic cast iron for maximum rigidity and good vibration damping.
- Designed to guarantee the maximum thermal stability.
- Gap bed and traversing wheelhead configuration.
- Mobile workhead with maximum swivelling diameter up to 256 inch.
- Different wheelhead configurations for OD, ID, turning and threading operations.
- Machining of the most advanced materials, such as HVOF, using the latest generation grinding wheels and dressing technologies.
- Filtration system to achieve a 15 micron filtration when machining HVOF.
- Internal and external grinding, turning, threading, superfinishing operations can be easily handled on the same machine through the use of a user-friendly new generation software.
- Automatic wheel balancing system with GAP & CRASH.
- Recognized by the major landing gear OEMs and MROs through out the world as the best gap bed grinding machine for landing gear application in aerospace machine tool market.
