1. Automatic cutting off machine tools

此机床采用了自动上料、自动送料和新型夹紧结构，这是我公司自主设计的，并且经过了多年实践检验的成熟技术。而且，送料稳定，切断精度高，上料、送料和回车速度远高于国内同类产品，大大缩短了辅助时间，提高了生产效率。

This machine tool has automatic feeding, automatic feeding and new clamping structure. This is a mature technology designed by our company and has been tested for many years. Moreover, the feeding is stable, the cutting accuracy is high, the feeding speed, feeding speed and return speed are much higher than that of the similar products in China, which greatly reduces the auxiliary time and improves the production efficiency.

2、自动镗床

2. Automatic boring machine

该机床采用钢管外圆定位，其理论定位基准与托辊工作基准重合。加工精度高，托辊径跳小，并可选配光栅数显装置，加工的止口深度可通过数显表显示出来，精度高且直观。

The machine tool uses the outer circle of the steel tube, and its theoretical positioning datum coincides with the working datum of the roller. The machining precision is high, the roll diameter of the roller is small, and the grating digital display device can be selected. The cutting depth of the machining can be displayed by the digital display table with high accuracy and intuitionistic accuracy.

3、自动焊机

3. Automatic welding machine

① 主轴支承采用了合理的滚动轴承支承，既能很好地导电，又能使其转动灵活，受热减少。

The main bearing of the spindle adopts a reasonable bearing of rolling bearing, which can not only conduct good electrical conduction but also make its rotation flexible and reduce heat.

② 改进了焊枪调整机构，既灵活又方便。国内部分产品，其焊枪调整机构不合理，调不动。经常是一个人拧手轮，另一个人到机床后面用力往上推，与自动机床极不相配。

(2) improving the adjusting mechanism of welding gun, which is both flexible and convenient. In some domestic products, the adjusting mechanism of the welding gun is not reasonable and can not be adjusted. It is often a man screwing a handwheel, the other pushes up behind the machine tool and does not match the automatic machine tool.
