方轨和圆轨的不同之处

The difference between square and circular rails

　　主要体现在以下几个方面：

Mainly reflected in the following aspects:

　　摩擦和负载能力：方轨是面接触式摩擦，摩擦力较大，但负载均匀，需要经常上油润滑。圆轨则是圆柱形的线型导轨，摩擦小，由于是一系列滚珠的点接触，需要支撑的地方有限，刚性差，负载性能有限，仅载径向有较好承载力，轴向承载比较小。

Friction and load capacity: Square rails are surface contact friction with high friction, but the load is uniform and requires frequent oil lubrication. Circular rails are cylindrical linear guides with low friction. Due to the point contact of a series of balls, the areas that need to be supported are limited, resulting in poor rigidity and limited load performance. They only have good radial bearing capacity and relatively small axial bearing capacity.

　　精度和重现性：方轨的定位精度高，重现性好，即使在微量进给时也不会有空转打滑的现象，可以实现μm级的定位精度。圆轨的精度稍差，但如果制作得好，可以达到10根左右的精度。

Accuracy and reproducibility: The positioning accuracy of the square rail is high, with good reproducibility. Even during micro feed, there will be no slipping phenomenon, which can be achieved μ M-level positioning accuracy. The accuracy of circular rails is slightly poor, but if made well, it can reach an accuracy of about 10 pieces.

　　耐磨损和高速性能：方轨耐磨损，高速，阻力小，对设备的驱动马力需求低，节省能源效果大，尤其运动磨耗小，温升效应低。

Wear resistance and high-speed performance: Square rail wear resistance, high speed, low resistance, low demand for driving horsepower of equipment, great energy saving effect, especially low sports wear and low temperature rise effect.

　　应用环境：方轨在家具工业中可能不太适用，因为在家具厂中尘土飞扬的环境中很难保持清洁，容易造成机器堵塞。而圆轨则简单，适用于多尘环境，易于维护。

Application environment: Square rails may not be suitable in the furniture industry because it is difficult to maintain cleanliness in dusty environments in furniture factories, which can easily cause machine blockage. The circular track is simple, suitable for dusty environments, and easy to maintain.

　　刚度和载荷能力：方形导轨产品能很好地满足高刚度、高载荷应用的要求，通过精密磨削滚珠轨道，使导轨与滚珠准确匹配。圆形导轨产品的刚度和承载能力则相对较弱。

Stiffness and Load Capacity: Square guide rail products can meet the requirements of high stiffness and high load applications well. By precision grinding the ball track, the guide rail and ball are accurately matched. The stiffness and load-bearing capacity of circular guide rail products are relatively weak.

　　成本和安装：圆导轨造价相对低廉、生产周期短、易于安装等特性，在很多场合成为方型直线导轨的替代品。

Cost and installation: Circular guides have the characteristics of relatively low cost, short production cycle, and easy installation, making them a substitute for square linear guides in many situations.

　　综上所述，方轨和圆轨的主要区别在于摩擦、负载能力、精度、耐磨损性、应用环境、刚度和载荷能力以及成本和安装方面。方轨适用于高精度、高负载的应用场景，而圆轨则更适合于成本较低、多尘环境的应用场合。

In summary, the main differences between square and circular rails lie in friction, load capacity, accuracy, wear resistance, application environment, stiffness and load capacity, as well as cost and installation aspects. Square rails are suitable for high-precision and high load application scenarios, while circular rails are more suitable for low-cost and dusty environments.
