AEROSPACE APPLICATIONS GRINDING MACHINES
DANUNI


DANUNI series for precision grinding of different aircraft landing gear struts. DANUNI machine range has been designed and developed for precision external and internal grinding of different aircraft landing gear struts, such as complex shaped pistons internal and external cylinders.

The DANOBAT Gap Bed Grinding Machine revolutionises the grinding process because it can swing the whole component between centres. With DANOBAT grinding machine range customers can obtain reduction of up to 50% in machining overhaul times due to the integration of OD and ID operations in one machine, providing a fast R.O.I.

A truly cylindrical and parallel surface is guaranteed which is superior to the results obtained with previously used grinding techniques. In the case of overhaul, this ensures that old plating is removed correctly. When the component is returned for final machining, the depth of plating is known accurately and is of uniform thickness. This level of precision, speed and accuracy is far superior to results previously obtained.

The machines are offered in different sizes, models and configurations depending on the application and customer requirements. Landing gear components requiring a swing of up to 4100 mm (161.5’’) can be handled. In addition the machine can grind internal bores up to 2550 mm (100.4’’) in length.
