Domestic nc system mainly rely on imports

The main conveyor parts at level of metal cutting machine, and other technical and complexity is not high, in recent years popular electric machine, also is the method, scientific and technological content of complexity and nothing.

Our nc grinder horizontal well, every year there are massive exports. Because it is simple, labor-intensive.

Metal processing is mainly removal of metal materials, get in shape. Remove materials, mainly by car, lathe, milling machine, and for CNC lathe, milling machine development development for machining center. High precision multi-axis machine, can make complex parts in precision and shape, such as the plane, you of a complex parts, by so many workers: before the machine, milling, Turner, painting line, heat treatment work for several months, including the latest composite scrapped, nc machine tools for days or even just a few hours all dry well, and the precision of the higher than your design. Precision parts as mean lifespan, good reliability.

The development of numerical control, a person to top ten in the original, but can't say the accuracy, adaptability, parts, a program. The factors to the lowest, in the factory, who previously when passing a worm, turbine, and 10 years in eight years, if who mastered, the ox. Now, as long as you use nc equipment will be lost in the parameter programming, ha ha, simple, graduate students ability. The product quality and quantity assured.

Since the late 1950s to make in the world a CNC lathe, conveyor parts manufacturing is entered in the 1960s, China will make the first generation of nc machine tools, but then China entered the, everybody knows what. As we'll see in the 1980s, the level of nc machine tools for 20 years, is still hope, but actually bent, state-run factories to 1990s, we'll go to see the world level, 30 years gap. We walked in the seclusion of the Soviet union, what is the way that the Soviet union, for example, for example, will produce a shaft, the Soviet union is a special way of production line, with more special machine tool, the benefit is easy, but the quantity of the axis once parameters changed, this line is discarded, production personnel is doing nothing. In 1960-1980, state-run factories in decades, a production never. In the 1980s, when make commodity economy, the factory can quickly adapt to the market, the business is difficult to 1990s of bankruptcy, a large number of laid-off workers. Ah, this is the laid-off workers.

Modern production has mass production, but mostly small batch, whether that piece of equipment, as long as you are used to control, quickly. Professional tool path has been exhausted, westerners is very clever, path and the soviets, "", Toshiba is Japanese Toshiba sold Soviet several sets of 5-axis CNC milling machine, let the Soviet union in advance of the submarine propeller manufacturing, a class, let us hear a voice sub sonar, so the United States to punish Toshiba. Thus, the Soviet union was also seen the machine manufacturing also left behind, they say, we will be more backward.
