The number of domestic drilling and milling machines has also dropped significantly in the past two years. Although China's machine tool consumption has ranked first in the world for 10 consecutive years, it has become the most active machine tool market in the world, but the domestic high-end market share of machine tools is still insufficient. The structural adjustment of the drilling and milling industry and the upgrading of products are imperative.

Experts said that the era of change in China's machine tool industry has arrived. The competitiveness of the milling machine market is the core task of the Chinese machine tool industry. According to the statistics, the market share of milling machines has been declining year by year, from 30.1% in 2000 to 28.1 in 2003. %, for this, it takes billions of dollars to import high-end CNC machine tools every year. This long-term situation of being controlled by people will surely pose a threat to the safe operation of China's economy.

Therefore, vigorously developing domestically produced gantry drilling and milling machines is an arduous task for the domestic machine tool industry in the next 5 to 10 years. High speed, high precision, high reliability, intelligence, flexibility, integration and openness are the main development directions of the CNC machine tool industry today. Recently, Jinan Shuochao CNC has developed a set of milling equipment for the end of H-beams used in the steel structure industry according to market demand. SX1000 H-shaped steel CNC locking and milling machine. The advantages of this CNC milling machine are as follows:

1. CNC Locking and Milling Machine Each spindle box is equipped with three milling cutters, which can simultaneously complete the machining of the bevel, end face and web arc groove of the workpiece through one feed.

2. CNC milling machine During the milling process, the milling feed rate can be automatically adjusted according to the machining position, which greatly improves the production efficiency and protects the tool.

3, CNC milling machine can achieve CAD / CAM direct conversion, thus eliminating the cumbersome operation of programming and input. The automatic generation of the machining program truly realizes the paperless processing of the equipment.

4. The ball screw pair, linear guide pair, electrical parts, servo motor and inverter of H-shaped steel CNC lock milling machine are all supplied by well-known domestic and foreign manufacturers, with few startup failures.

We can see from the product advantages that the domestic CNC milling machine has a self-evident advantage compared with the foreign numerical control system and enters the Chinese market. We can also see that the domestic CNC drilling machine is after-sales service compared with foreign countries. In terms of low-end and medium-end applications, domestic CNC drilling and milling machines not only have an absolute advantage in price, but also inferior to the products of any foreign manufacturers in terms of product quality and reliability.
