In order to explore the influence of ultrasonic-assisted grinding on the grinding force in the machining process, a new dynamic grinding force model of ultrasonic-assisted single abrasive high-speed grinding is established based on the fact that the abrasive particles are constantly worn in the machining process.
Main Journals Machining. The main journals, also called main bearing journals, are the important part of crankshaft. The precision of its dimension is important to the installation of crankshaft. All the crankshaft journals should be machined as smooth and rounded as possible. Nazhen has professional CNC turning lathe and CNC grinding machine.

Hide abstract. Electrical machining remains an important area of industrial activity and research in the UK. Historically, British universities have made notable contributions which have helped to shape the state-of-the-art. There is also a healthy network of machine makers and machine users in the UK which support the stalwart aerospace industry.
Grinding process quality, accuracy and the resulting workpiece surface quality were affected by the forces in grinding. Grinding forces consist of frictional force, chip forming force and ploughing force respectively by rubbing, cutting and ploughing actions. All the three forces are greatly dependent on process parameters [12].
Major contributions to machining and grinding research in the US came in the twentieth century. The seminal work by Frederick Winslow Taylor on the Art of Cutting Metals published in 1907 was the beginning of a series of serious and systematic studies on the various aspects of metal cutting and grinding in this century. This monumental work, which became an American classic, continues to ...

It is necessary now to develop environment friendly and work place friendly machining systems. The current study is to assess the Nanofluids Minimum Quantity Lubrication Technique (NFMQL) on different properties of grinding. The grinding of Inconel 718 under NFMQL was evaluated and compared with pure and flood lubrication grinding.
Abrasive grinding is still a key method of efficiently and accurately shaping workpieces, especially those made of difficult-to-machine construction materials with high hardness and strength, e.g., titanium, magnesium alloys, nickel and cobalt-based superalloys, Inconel, etc. [1,2,3].The increasing requirements for modern manufacturing processes in the field of: dimensional accuracy, surface ...
