How to control the thermal deformation of machine tools
CNC lathe manufacturers have been to control the machine tool thermal deformation precision machining as a focus, affecting the machine thermal deformation of the factors is very complex. Moreover, the modern cutting of high-speed, high efficiency, precision three simultaneously, then the machine's thermal deformation problem is more prominent. Caused a wide range of machine tool manufacturing industry attention. Domestic and foreign machine tool industry scholars have done a lot of research, in theory, made considerable progress.
Thus, we believe that the optimal design of machine thermal performance should proceed from the following aspects:
(1) the design stage of modern high-end machine tools, should pay attention to the future design of machine tools for environmental conditions.
(2) control and configure the heat source is the key. Control of heat mainly refers to the control of energy consumption and power source matching, the use of new structure, reduce the secondary friction heat source, improve energy efficiency. The following are the same as the "
(3) to change the traditional thinking, the cooling, cooling, lubrication, chip and other devices from the machine "auxiliary" component status, to enhance the "important" component status, can not be ignored.
(4) attention to the structure of the symmetry and thermal deformation of the direction of the design, so that the impact of thermal deformation on the accuracy to a minimum, in particular, to attach importance to structural deformation of the mathematical model of thermal deformation research and application in order to provide thermal deformation control design to provide qualitative Quantitative instructions.
