Advantages and Characteristics of Linear Guides:
1. High positioning accuracy:
When using linear guides as linear guidance, the friction mode of linear guides is rolling friction. The friction coefficient is reduced to 1/50 of that of sliding guidance. The difference between dynamic and static friction forces becomes very small. Therefore, there will be no slipping phenomenon when the table moves, achieving ultra-high precision level accuracy of micrometers.
2. Minimal wear, maintaining accuracy for a long time:
Traditional sliding guides inevitably result in poor platform movement accuracy due to the reverse flow of oil film and insufficient lubrication during motion, leading to wear on the contact surfaces of the running tracks and significantly affecting accuracy. In contrast, rolling guides have very little wear, allowing the machine to maintain accuracy for an extended period.
3. High-speed motion with reduced power requirements:
Due to the minimal friction force during linear guide movement, only a small amount of power is needed to drive the table. This is particularly advantageous for applications involving frequent reciprocating motion of the table, as it significantly reduces power loss. Additionally, the minimal heat generated by friction makes it suitable for high-speed operation.
4. Can withstand loads in all directions:
Due to the special structural design of linear guides, they can simultaneously bear loads in all directions (up, down, left, and right). Unlike sliding guides, which have a lighter load-bearing capacity in the lateral direction on parallel contact surfaces, causing poor machine movement accuracy.
5. Easy assembly and interchangeability:
During assembly, the assembly surfaces of the linear guides and sliders on the table only need to be milled or ground, and then the guides and sliders are fixed to the machine table with specified torque according to the recommended steps. This ensures high precision during processing. In contrast, traditional sliding guides require scraping of the running tracks, which is time-consuming and labor-intensive. Moreover, if the machine accuracy is poor, scraping needs to be repeated. Linear guides have interchangeability, allowing for the replacement of sliders or guides separately to form a linear guide set, enabling the machine to regain high precision guidance.
6. Simple lubrication structure:
Insufficient lubrication in sliding guides can directly cause metal-to-metal friction and wear on the contact surfaces of the table. Adequate lubrication for sliding guides is not easy and requires drilling oil holes in appropriate positions on the table for oil supply. On the other hand, linear guides are equipped with oil nozzles, allowing direct injection of grease with a grease gun. They can also be connected to dedicated oil pipes for automatic lubrication.
Linear guides, also known as linear rails, slide rails, linear guideways, or linear slides, are used in linear reciprocating motion applications and can withstand certain torque to achieve high-precision linear motion under high loads. They are referred to as linear guides on the mainland and linear guideways or linear slides in Taiwan. The purpose of linear guide motion is to support and guide moving components to perform reciprocating linear motion in a given direction. Depending on the friction characteristics, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides. Linear bearings are mainly used in automation machinery, such as imported machine tools, press brakes, laser welding machines, etc. Linear bearings are typically used in conjunction with linear shafts. Linear guides are primarily used in machinery structures that require high precision. The moving element of a linear guide and the fixed element do not require an intermediate medium and instead use rolling steel balls. Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving components to perform reciprocating linear motion in a given direction.
