钢筋混凝土振动挤压管的生产工艺规定,为了确保承口工作面的尺寸,必须进行磨光。用碳化硅砂轮磨光管子,劳动量大、生产率低,而且设备保养费相当可观。同时,加工质量也差。在加工天然石块时应用金刚石刀具的经验证明,用人造金刚石是可以提高钢筋混凝 The production process regulations for reinforced concrete vibrating extruded tubes must be polished in order to ensure the dimensions of the mouthpiece face. Polishing tubes with silicon carbide grinding wheels has a large amount of labor and low productivity, and equipment maintenance costs are considerable. At the same time, the processing quality is also poor. The experience of applying diamond tools in the processing of natural stones proves that using synthetic diamond can increase the rebar coagulation
