Design Of High-Speed Grinding Wheel Machine And Simulation Of The Temperature Field For Cutting Area

Thin resinous grinding wheel (here in after referred as grinding wheel) is one of the most common products in abrasive field. However, in the field of high-speed sawing, there is a wide gap between domestic and foreign products. Now, the domestic companies have begun to engage in the development of high-speed grinding wheel products. To ensure the grinding wheel to be security and stability under high-speed operations, the products of grinding wheel have stringent criterion in the process of confect, product, material choice and check. The check process including flatness detection, static balance detection, rolling test as well as cutting test and so on. Cutting test as the final process before production get out of factory, its data is a direct reflection to the quality of a number of grinding wheel.In allusion to the defect in actual saw cutting testing machine, the requirement of saw cutting testing machine and it's components under high speed condition were analyzed. Proposed an recapitulative design scheme of the testing machine and the solution of each components. Under the program, designed and manufactured high-speed saw cutting testing machine. The machine achieved the force loading of fixed value in the process of cutting test, solved the potential problem of hot in bearing and shaking in machine, achieved in the clamp and rolling of large diameter workpieces. According to the actual circumstances of cutting test, the article given a method of how to judge the quality of grinding wheel, taken out a conception of cutting efficiency.In order to study the capability of high-speed grinding wheel in machining large-diameter workpieces, offer academic bases to high-speed and high-efficiency cutting machine tool, this article used experimental and simulative method to analysis the lapse rate around grinding wheel. Test collected mutative temperature data around grinding wheel when incise the workpiece with a diameter of 160mm round. Analysis of the sawing condition, come into the sawing model and the loading model of boundary condition. Based on the above analysis, language of APDL was used to finish modeling, loading, meshing and solution of entity. Finally, the paper got the results of analysis data, as well as temperature distribution graph. Contrasting with the collecting data, then achieve the aim of theory guidance of practice.
