    • PURPOSE: A method to manufacture a base structure for a machine tool to reduce a thermal displacement and a base structure manufactured by the same are provided to improve machining accuracy of the machine tool by flowing a cooling medium after a cooling flow path is formed by connecting different kinds of pipe in a part in which cooling is required and reducing entire temperature deviation of a bed and a column. CONSTITUTION: A method to manufacture a base structure for a machine tool to reduce a thermal displacement comprises the steps of: surface-processing different kinds of pipe (20) in a plating or spraying method; installing the different kinds of pipe on a mold in a molding process and a coupling process; inducing air or nitrogen gas inside the different kinds of pipe with a pressure of 1-3 Bar, 3-6 Bar, or 6-9 Bar for 10-30, 30-60, or 60-90 minutes in a process pouring molten metal and cooling the same until the temperature of a connecting surface (30) reaches 1,150-1,000 °C or 1,000-600 °C.
    • 目的:提供一种制造用于机床的基础结构以减少热位移的方法以及由其制造的基座结构,以通过在形成冷却流路之后流动冷却介质来提高机床的加工精度 在需要冷却的部分中的不同种类的管道,并降低床和塔的整体温度偏差。 构成:制造用于机床的基础结构以减少热位移的方法包括以下步骤:以电镀或喷涂方式对不同种类的管(20)进行表面加工; 在成型工艺和连接工艺中将不同种类的管安装在模具上; 在1-3巴,3-6巴或6-9巴的压力下,在不同种类的管内引入空气或氮气10-30,30-60或60-90分钟,在浇注熔融金属的过程中 并进行冷却,直到连接面(30)的温度达到1,150-1,000℃或1000-600℃。
