Research For Machine Tool Grinding Center

With the rapid development of machinery manufacturing industry, Especially the wide application and popularization of CNC machining technology, flexible processing and unmanned workshop. For the requirements of more and more high stability of the cutting process, the manufacturing and cutting tool angle grinding accuracy requirements are also getting higher and higher. In this paper, combined with the development of the manufacturing industry needs, research and design of the economical CNC blade which has the advantages of simple structure, convenient operation and grinding equipment to design of a machine tool grinding center. The device can automatically grinding tool, drilling and other commonly used Hemp flowers, important metal cutting tool.Thesis focuses on the machine tool grinding center to realize automatic grinding part Hemp flowers drill.Drilling is the most common processing method in mechanical processing and production processing, is one of the most important machining process in metal cutting, about the 30~40% of the metal cutting. So, the reasonable selection of geometric angle of cutting tool, drilling and shape can greatly improve the drilling performance and the machining quality and efficiency. With the development of manufacturing industry, for the tool grinding and re-grinding blade wear after will tend to automatic grinding. This paper combines the Hemp flowers drill grinding principle and method, design an automatic grinding machine.Thesis firstly discussed the existing research Hemp flowers in blade drill grinding method, combined with the Hemp flowers drill cone grinding method to establish the mathematical model, established in Hemp flowers drill for the origin of the coordinate system, the former flank grinding mathematical model, combined with the drill geometry and geometry Hemp flowers, study and discuss the grinding parameters for the influence of geometric parameters of drill.In determining the basis of grinding method and motion form, and then determine the structure type grinding machine. Machine tool based on space coordinate system, analysis of the relationship between the coordinate of machine tool and tool coordinate system, determine the position of cutter grinding machine of the grinding wheel and relationship between drill, the amount of movement of reasonable selection of grinding parameters determine the machine in each direction and rotation angle in order to achieve edge drill grinding.In the process of machine mechanical structure design, mainly on the ball screw nut pair, linear rolling guide and worm type turntable were calculated checked to ensure the accuracy of mechanical transmission components and stiffness. Finally, drawing the assembly draw of device used software.
