Drilling and tapping center is a kind of metal cutting equipment. Its style and function are basically similar to machining center, but it is smaller than machining center. Generally, the stroke is no more than (x / y) 800 × 400mm. It is mainly used for drilling and tapping of nonferrous metals, 3C industry, aluminum substrate, etc. Although it can realize boring and milling, due to the low power of main motor, it can’t carry out heavy tapping of ferrous metals Cutting, but the efficiency and quality of drilling and tapping speed is more than 10 times of that of ordinary machining center. For 3C, communication industry and other industrial customers, it is the most ideal processing equipment.
Current overall market analysis:
Due to the rise of mobile phone industry, communication industry and tablet computer industry in recent years and the continuous upgrading to please consumers, the accompanying supporting processing industry is also rising, especially the demand for drilling machine is growing.
In the early stage of drilling and tapping center, the water-based cutting fluid (water-based) was used in the separate cooling water tank, and both stations were used. However, after a period of time, it was found that the water-based cutting fluid of drilling and tapping center was not good for drilling and tapping threads, especially for taps, which were “astringent” during machining and were very easy to break, and the quality of the tapped holes was not good. Therefore, we changed the drilling center to dry machining. When we arrived at the tapping station, kerosene was used for lubrication (kerosene was supplied by the pump alone, and the electrical control) to produce good thread quality, and the tap was rarely broken. The processing form of drilling and tapping Center: manually push the material to the conveying position, press the “swing up” button to enter the automatic cycle, and the two headstocks act at the same time. After the second feeding, the two headstocks return to the original position.
CNC machine tool is a widely used drilling and tapping center. CNC machine tool is a kind of advanced equipment with excellent performance, wide range of technology, high precision of drilling and tapping center and high production efficiency. One time clamping can complete drilling, reaming, boring, grooving and plane milling. In addition, it can also process holes with high precision. CNC machining is used for heavy machinery, engineering machinery, rolling stock, mining equipment, large motor and water turbine , steam turbine, shipbuilding, steel, military and other industrial sectors essential processing equipment. The CNC machine tool has the characteristics of good rigidity, high precision, strong reliability, convenient operation, beautiful appearance, etc., especially in the end face of square ram, it can also install various accessories or cooperate with the rotary table, which can further expand the application scope of CNC machine tool. CNC machine tools are mainly used for boring large and medium-sized parts of the hole, but also can complete drilling, expanding, reaming, milling plane and other work. The CNC machine tool is equipped with a change gear device, which can process metric or English internal thread. The end face can be turned by using the flat disc radial tool rest, which can be used online with the rotary table, and the inner hole and outer circle with large diameter and short length can be processed.
