Lubrication and cooling of a high speed grinding process in the grinding machine as in a mechatronic system using technological liquids are analyzed in this paper. It is shown that in the case of high grinding speed, technological liquids undergo an aeration process and due to this their physical properties change. Reynolds equation, which estimates the aeration liquid, is derived. It is shown, that the application of such an equation is proper only in the finishing of grinding. Experimental research is also presented in the paper, which shows the influence of technological liquids to the temperature field of the grinding machine and to its automatic control.

Ultra-high speed grinding (UHSG) is a significant and promising machining technology in grinding hard-to-cut materials. To find out the aerodynamics of the grinding wheel body when the airflow field has subsonic, transonic, and supersonic speed characteristics and clarify the corresponding influence on the grinding mechanism, the study is conducted to develop a supersonic grinding machine tool that is capable of being operated at extreme wheel speed up to 450 m/s and meanwhile accompanying with high grinding capability. In accordance with the main design objectives, a high performance grinding motorized spindle with maximum rotational speed 36000r/min and maximum power 28kW is developed. The linear motor feed driven system is also exploited to satisfy the requirement of maximum reciprocating speed up to 2m/s. Following plenty of specific design and performance analysis works, a prototype of supersonic grinding machine tool is finally developed. In the end, this paper also puts forward a number of further studies and prospective for the research activities on basis of the developed grinder.

Grinding wheel unbalance will result in vibrations of grinding machines and affect the quality and precision of workpieces. Therefore, a balancing system is necessary for grinding machines to lower the vibrations caused by unbalance. In this study, a liquid transfer active balancing system, in which the balancing liquid was forced by compressed air to transfer between opposite chambers, was applied to the high-speed grinding spindle. The requirements of gas pressure and linearity of balancing ability were analyzed to confirm the feasibility of the proposed device. In addition, an active balancing experiment was also carried out efficiently during the operation.
