Abstract: The high efficiency deep grinding is widely used in manufacturing. The experiments were carried out to study on the high speed deep grinding force and grinding burn and cracks in grinding 40Cr steel specimen with Al₂O₃ wheel. The experimental studies demonstrate that the grinding force increases with the grinding layer depth. The trail of grinding on space surface is blurred progressively, the surface topography deteriorates gradually. When the depth of grinding increases to the certain value, grinding burn appears, and micro-cracks emerge. Selecting the optimization parameter in high speed deep grinding can avoid the grinding burn and grinding cracks.

Abstract: The mechanism and characteristic of high speed grinding and the technology and development of high speed grinding were introduced. High efficiency grinding including ultrahigh speed grinding, high efficiency deep grinding, creep deep grinding and abrasive belt grinding was analyzed. The technology about manufacturing the spindle system in super high speed grinding and the other main interrelated technology about grinding were also described.

Abstract: Focusing on the characteristic of hard-to-grinding for viscous materials, such as titanium alloy, systemic process experiments were done about grinding viscous materials, such as TC4 titanium alloy, under the high efficiency deep grinding (HEDG). Based on the analysis to the changing and characteristic of unit area grinding force F' with maximum undeformed chip thickness hmax and equivlent cutting thickness aeq , this paper discussed the changing of its material removal mode and analyzed the changing and characteristic of grinding force ratio N, specific grinding energy es with corresponding parameters further. Then, it was analyzed about the consumption of grinding power on the process of HEDG for TC4 titanium alloy. The experiment results reveal that application of HEDG can improve machining efficiency of grinding viscous materials.
