Increased by 15.1%. According to Sheng Laiyun, spokesperson of the National Bureau of Statistics, in the first quarter, the added value of industrial enterprises above designated size grew by 14.4% year-on-year. In terms of sub-industries, 39 major industries have achieved growth. Industrial production and sales were in good condition. In the first quarter, the production and sales ratio of industrial enterprises above designated size reached 97.7%, which was 0.1 percentage point higher than the same period of last year. In addition, from January to February, the industrial enterprises above designated size achieved a profit of 645.5 billion yuan, a year-on-year increase of 34.3%. Among the 39 major industries, the profits of 38 industries increased year-on-year, and the loss of one industry decreased. Data show that in the first quarter, the industrial added value of chemical raw materials and chemical manufacturing industry increased by 15.1% year-on-year; natural crude oil production reached 51.36 million tons, a year-on-year increase of 6.7%. In addition, in the first quarter, the industrial production price (PPI) rose by 7.1% year-on-year, and the purchase price of industrial production rose by 10.2% year-on-year. Among them, the purchase price of industrial production of chemical raw materials increased by 11.8% year-on-year. In the first quarter, the import record was high and the trade experienced a quarterly deficit, which is also the first quarterly deficit in six years. Data show that in the first quarter, the total import and export volume of the country was 800.3 billion U.S. dollars, an increase of 29.5% year-on-year.

Structural characteristics of CNC vertical lathe:
CNC vertical lathe is a CNC vertical lathe whose main structure is base and single column type structure with table, fixed beam, square ram and single tool holder structure, which is an economic CNC vertical lathe with high rigidity and high cost performance. The casting process of CNC vertical lathe is large in volume and complex in structure, the amount of iron liquid poured is large, the cooling time of the casting is long, and casting defects such as shrinkage, shrinkage, pore, crack and substandard mechanical properties are easy to appear, and it is difficult to control the production process. The base, column and beam of CNC vertical lathe are made of high-strength cast iron with good shock absorption; the large span hardened guide rail has good wear resistance and long-lasting precision maintenance. Symmetrical box structure can carry heavy cutting with high torque. The ram adopts square structure, with good precision. Fixed cross beam, good rigidity and high precision. CNC vertical lathe single tool block structure, stable and reliable precision. Centralized machine operation panel â—‡Makes the operation more convenient and quick. It can process various internal and external cylindrical surfaces, conical surfaces, circular curved surfaces, etc. CNC vertical lathe is suitable for processing parts such as motor shells, large and medium-sized disk sets and covers. It is suitable for electromechanical, automobile, wind power, engineering machinery and other industries.
