Manufacturing industry is a part of the main body of China's economy. Modern China is famous for its "world factory", but because there are many problems, the impression of domestic goods is good or bad. In order to change this situation and improve the grade and technology of the domestic manufacturing industry, the state attaches great importance to the manufacturing industry. Blow molding machine equipment is mostly used in the domestic manufacturing industry, and the composition of machine tool is inseparable from linear guide rail.

國內經濟處于快速增長的勢頭，國內制造業也處于轉型階段，為導軌絲杠產品提供了巨大的市場空間，這個龐大的市場吸引了眾多國外知名導軌生產企業前來投資合作，同時也促進了國內導軌行業的快速發展，導軌絲杠制造業所形成的龐大生產能力讓世界刮目相看。隨著電力工業、數據通信業、城市軌道交通業、汽車業以及造船等行業規模的不斷擴大，對直線導軌的需求也將迅速增長，未來直線導軌行業還有巨大的發展潛力。

The domestic economy is growing rapidly and the domestic manufacturing industry is also in the transformation stage, which provides a huge market space for guide rail lead screw products. This huge market has attracted many well-known foreign guide rail manufacturers to invest and cooperate, and also promoted the rapid development of domestic guide rail industry, The huge production capacity formed by the guide rail lead screw manufacturing industry has impressed the world. With the continuous expansion of the scale of China's power industry, data communication industry, urban rail transit industry, automobile industry, shipbuilding and other industries, the demand for linear guide rail will also grow rapidly. In the future, the linear guide rail industry still has great development potential.

直線導軌一般分為兩類，分別是方形導軌和圓形導軌兩種類型。圓形導軌是早出現的產品，但相比方形導軌精度較差。不過圓形導軌非常適合垂直移動重負載的場合。具體使用哪種直線導軌應該根據實際導軌應用需求來決定。

Linear guide rail is generally divided into two types: square guide rail and circular guide rail. Circular guide rail is an early product, but its precision is poor compared with square guide rail. However, the circular guide rail is very suitable for vertically moving heavy loads. The specific linear guide rail should be determined according to the actual guide rail application requirements.

方形導軌設計固有的各種磨制要求導致其初期成本是圓型導軌的數倍，但隨著直線導軌制造技術導軌的表現要優于圓形導軌。在一般情況下，方形導軌具有更高的負載能力、精度和剛度以及更長的使用壽命。

Due to various grinding requirements inherent in the design of square guide rail, its initial cost is several times that of circular guide rail, but with the manufacturing technology of linear guide rail, the performance of guide rail is better than circular guide rail. In general, the square guide rail has higher load capacity, accuracy and stiffness and longer service life.

不同行業對導軌類型的需求也是不同的，我們應該按照自己的時間情況挑選適合自己的導軌設備，國內的導軌市場還處于發展中，期間會出現這樣那樣的問題，我們應該重視這些問題并解決它，這樣才會使導軌行業發展更快，走的更遠。

Different industries have different needs for guide rail types. We should select suitable guide rail equipment according to our own time situation. The domestic guide rail market is still developing, and there will be such and such problems during this period. We should pay attention to these problems and solve them, so as to make China's guide rail industry develop faster and go further.
