There is a significant difference between linear guides and ball screws. Although both belong to linear transmission equipment, their working principles, requirements, and scope of use are different, but their performance in linear transmission is excellent. Ball screw is the most commonly used transmission component in tool and precision machinery, consisting of screws, nuts, steel balls, pre pressing plates, reversers, and dust collectors. Its main function is to convert rotational motion into linear motion or torque into axial repeated force, while also possessing the characteristics of high accuracy, reversibility, and high efficiency.

主要用于一些機(jī)床大型設(shè)備、雕刻機(jī)械等較為普遍，非常方便的把旋轉(zhuǎn)的運(yùn)動(dòng)轉(zhuǎn)換成直線運(yùn)動(dòng)，用起來非常方便，從而減少整個(gè)設(shè)備在旋轉(zhuǎn)方面的磨損大大降低。直線導(dǎo)軌使用較為廣泛但種類很多，方型四排高珠導(dǎo)軌用于一些大型機(jī)床設(shè)備，如平面磨床，切片機(jī)、線切割等；也因工作條件的不同選用的直線導(dǎo)軌也是不同的，更適于精密測(cè)量?jī)x器、半導(dǎo)體制造和檢驗(yàn)設(shè)備、非標(biāo)自動(dòng)化機(jī)械設(shè)備以及其他精密直線運(yùn)動(dòng)至為重要的應(yīng)用場(chǎng)合等，因不同設(shè)備需要選擇正確的導(dǎo)軌也是至關(guān)重要的。

It is mainly used for some large-scale machine tools, carving machinery, etc. It is very convenient to convert rotating motion into linear motion, which is very convenient to use, thereby reducing the wear and tear of the entire equipment in terms of rotation. Linear guide rails are widely used but have many types. Square four row high ball guide rails are used for some large machine tools and equipment, such as surface grinders, slicers, wire cutting, etc; The selection of linear guides varies depending on the working conditions, and is most suitable for precision measuring instruments, semiconductor manufacturing and inspection equipment, non-standard automated mechanical equipment, and other applications where precision linear motion is crucial. Choosing the correct guide is also crucial for different equipment needs.

滾珠絲桿的特性：與滑動(dòng)絲桿副相比驅(qū)動(dòng)力矩為1/3、高精度的保證、微進(jìn)給可能、無側(cè)隙、剛性高、高速進(jìn)給可能。直線導(dǎo)軌的特性：定位精度高、磨耗少能長(zhǎng)時(shí)間維持精度、使用高速度運(yùn)動(dòng)且大幅降低機(jī)臺(tái)所需驅(qū)動(dòng)馬力、可同時(shí)承受上下左右的負(fù)荷、組裝容易并具互換性、潤(rùn)滑結(jié)構(gòu)簡(jiǎn)單。

The characteristics of ball screw: Compared with sliding screw pairs, the driving torque is 1/3, ensuring high accuracy, possible micro feed, no backlash, high rigidity, and possible high-speed feed. The characteristics of linear guide rail include high positioning accuracy, low wear, ability to maintain accuracy for a long time, use of high-speed motion and significantly reduce the required driving horsepower of the machine, ability to simultaneously bear loads of up, down, left, right, easy assembly and interchangeability, and simple lubrication structure.
