Figure 1 shows the diagram of UASG and UAEG; where the workpiece coordinate system OXYZ is taken as the global coordinate system, a p is the grinding depth (μm), b is the grinding width (mm), and A is the ultrasonic amplitude (μm). As shown in Fig. 1(a) and (b), the longitudinal ultrasonic vibrations are parallel and perpendicular to the machined surface respectively.
Ultrasonic vibration assisted grinding (UAG) is a nonconventional machining process which plays an important role in machining hard and brittle material with a success in terms of decreased cutting force, extended tool life and significant reduced cutting temperature [15], [16], [17].
Tencan ultrasonic planetary ball mill is small in volume, full of functions, high efficiency and low noise. It is an ideal equipment for scientific research units, colleges and universities and enterprise laboratories to get research samples (four samples at one time in each experiment) it is also used for grinding samples under vacuum state.

The ultrasonic vibration millgrinding process can be considered as a combination of ultrasonic vibration machining process and millgrinding process. As shown in Fig. 1(a), the grinding wheel's motion relative to workpiece in UVMG includes the rotation motion in its own axis and the feed motion along a helical path.
Bone Mill. Our Bone Mill streamlines the preparation of harvested autologous bone by saving time and reducing manual effort. Winner of the 2011 Medical Design Excellence Award, Bone Mill efficiently and consistently reduces bone into appropriately sized particles with a lowheat, singlepass cutting action.
This characteristic generally exists in the ultrasonic grinding and filing process because the vibration is vertical to the feed direction and parallel to the machining surface. The ultrasonic grinding (Wang et al., 2014) and filing (Wang et al., 2016) are conducted on the advanced ceramic and C/SiC using various tools.

An ultrasonic grinding mill was designed. It permits to carry out simultaneously intensive ultrasonic, mechanical and cavitation treatments of powder materials that in turn leads to sharp acceleration of diffusion, masstransfer processes and solid phase reactions due to crystallite size and structure changing.
It can also be used to cut heterogeneous samples such as frozen chicken parts including bones. For grinding thin plastic foil, which is usually a part of refusederived fuels, it is recommended to use dry ice due to the continuous cooling effect during the grinding process.
