The air-lubricated pneumatic workbench introduced in this paper is used in rotary ultrasonic machining which are widely used to machine hard and brittle materials.
A new type of rotary ultrasonic grinding cutter is developed, which can be mounted on the general purpose machine tool used to machine the hard brittle materials [1-2].
It is very useful to machine the hard brittle materials by rotary ultrasonic machining.
Fig. 1 Air bearing and guide way Fig. 2 Throttle orifices and restrictors Fig. 3 CAD model of the pneumatic workbench Fig. 4 The air-film thickness when The air bearing can automatically slide down along the guide way when the loads in the vertical direction larger than certain force and protect the tool from sharply wearing or even fracturing while drilling small-diameter deep hole on the hard brittle materials.
