Development history of vertical drilling machine

Development history of vertical drilling machine
In the early 1970s, the drilling machine was controlled by common relay in the world. In the late 1980s, because of the emergence of numerical control technology, it gradually began to be applied in deep hole drilling machine, especially after 90 years, this advanced technology was promoted. For example, in the early 1990s, the ML series deep hole drilling machine of TBT company was listed in the market, except that the feed system was changed from mechanical CVT to AC servo motor driven ball screw pair, and the slide guide for feed was rolling linear guide. In order to ensure high-speed rotation and stable accuracy, the drill pipe box drive was changed from the exchange pulley and belt, and the step drive driven by two speed motor to the variable frequency drive of CVT Driven by electric motor to electric spindle, it creates favorable conditions for drilling small hole deep hole drilling machine and improving the horizontal quality of deep hole drilling machine. In order to process the cross or any angle of some parts, or the inclined hole, vertical hole or parallel hole which is at a certain angle with the center line of processing parts, various countries have developed a variety of special deep hole drilling machines. For example, the special purpose is to process the oil hole on the crankshaft, the inclined oil hole on the connecting rod, the parallel hole and the multiple radial discharge holes of the feeding die of the feed machine. It is especially suitable for bw250-kw deep hole drilling machine of large and medium-sized truck crankshaft oil hole. They all have X, y, Z, w four axis numerical control. In order to meet the needs of customers, a variety of crankshaft oil holes can be processed on a production line. In 2000, the first flexible crankshaft machining center was designed and manufactured, which can process all oil holes on different crankshafts of 2-12 cylinders. A special deep hole drilling machine with six equal spindles and six holes on the same workpiece, which is specially developed by mollart company for processing particle extrusion die. The number of holes in the workpiece is up to 36000. It's all controlled by the CNC system
