High-speed machining is playing a more important role in modern manufacturing technology. The feed system of high-speed machine tool is one of the most important components. The linear motor has been widely used in high-speed machine tool. In this paper,a kind of machine tool feed system directly driven by a linear motor is introduced,and its technical parameters are analyzed and calculated. The main parameters’ influence factors and best scope are given out.These results can offer theoretical basis for manufacturing machining technology.

— High speed machine tool is one of the basic needs in catering to a wide range of machining parameters with tight tolerance band. In high speed machine tool many key factors like geometric, cutting force and thermal errors decides the performance of the machine. However amongst these three, error due to thermal deformation is an important factor in influencing the accuracy level of component produced. A survey amongst Indian machine tool manufacturers reveals that there is a strong need to infuse recent technological developments in thermal error prediction and derive methodologies to minimize the same in high speed machine tool. This paper attempts snapshots of a review relating to the errors causing thermal deformations and the modeling techniques developed by researchers and practitioners globally in present scenario. The conclusions made at the end of this paper may not give the full solutions to the problems relating to thermal error but, gives a broad perspective for the Indian machine tool manufacturers’, practitioners as well researchers in India to look in to the research relating to thermal error modeling, analysis and corrective measures.

To design a machine tool successfully, its essential parts should be analyzed and evaluated after design but before prototype being made. The spindle assembly is one of the most essential parts of high speed machine tool, so how the dynamic characteristics of the spindle assembly affect the performance of high speed NC machine tool are of great significance and should be studied. This paper’s research is based on a high speed machine tool manufactured by some plant. The finite element analysis model of the spindle assembly of the high speed machine tool was developed by taking the advantage of the spring-damper element to simulate the bearing supports. The modal analysis was made to confirm the dynamic characteristics of the spindle assembly, and the results were compared with the testing ones.
