中小型金属切削机床,重量一般小于5～7吨。这类机床的基础安装工作,須严格按机床基础安装图的要求和施工驗收規范进行,以防止产生机床震动、避免过早的磨損而影响精度及使用寿命,从而保証加工零件的精度和光洁度。这里着重介紹中小型金属切削机床两种基础安装的方法。一、直接安装在混凝土地坪上机床直接安装在混凝土地坪上时,最好采用預留地脚螺絲孔的方法。地坪采用混礙土标号一般为:R_u=100公斤/厘米~2,混凝土强度达到0.5R_u时,才允許安装机床。在机床开始工作时,混凝土的强度应不低于0.7～0.75R_u;在急于开动机床的情况下,可以搀
Small and medium-sized metal cutting machine, the weight is generally less than 5 to 7 tons. The basic installation of such machine tools, should be strictly in accordance with the requirements of the basic installation drawings and construction acceptance specifications to prevent machine vibration, to avoid premature wear and tear affect the accuracy and service life, thus ensuring the accuracy and finish machining parts. Here focuses on small and medium-sized metal cutting machine tools, two kinds of basic installation methods. First, the direct installation on the concrete floor machine directly installed on the concrete floor, it is best to use reserved foot screw hole method. The floor is mixed with soil markings generally as follows: R_u = 100 kg / cm ~ 2, the concrete strength reaches 0.5R_u, before allowing the installation of machine tools. When the machine starts to work, the strength of the concrete should be not less than 0.7 ~ 0.75R_u; in the case of eager to start the machine, you can mix
