机床的热变形,主要因机床各部分温度变化不同,使其各部分体积膨胀不一所致。随着生产过程自动化和精密加工的迅速发展,机床热变形对加工精度的影响已日益引起普遍重视,都在从设计、制造和使用等方面研究相应措施,来减少机床的热变形和抵消热变形所造成的不良影响。用反变形来抵消热变形的不良影响,是一种简单易行的有效方法。
Machine tool thermal deformation, mainly due to different temperature changes in various parts of the machine, making its various parts of the volume expansion due to different. With the rapid development of production process automation and precision machining, the influence of machine tool thermal deformation on machining accuracy has been paid more and more attention. All of them are studied from the aspects of design, manufacture and use to reduce the thermal deformation of machine tool and offset the thermal deformation Caused by the adverse effects. Anti-deformation to offset the adverse effects of thermal deformation is an easy and effective method.
