The guide motion that supports and guides moving parts and performs reciprocating linear motion in a given direction is called linear guide motion. Linear guides can be divided into three types: roller linear guides, cylindrical linear guides and ball linear guides. Let me show you the advantages of linear guides.
1. Linear guide assembly is convenient and simple
High-quality assembly can be completed with a little training. Because the accuracy of machine tools is determined by the accuracy of the transmission mechanism, the transmission mechanism generally consists of linear guides and screws, that is to say, the accuracy of the linear guides and screws themselves determines the accuracy of the machine tools, and linear guides and screws generally exist in the form of standard parts. As long as you choose the corresponding accuracy provided by the manufacturer, there will generally be no big problems.
2. There is a wide range of choices for linear guides
Whether it is the structural form or accuracy level of the linear guide, lubrication method or load-bearing capacity, processing method to running speed and other parameters, you can choose any linear guide model you need according to the specific situation of the machine tool you designed.
3. Fast running speed of linear guides
Nowadays, many machine tools run at extremely high speeds, especially the idle speed. This is largely due to the credit of linear guides, because the rolling friction operation mode and high-precision processing effectively guarantee the accuracy and stability of high-speed operation of machine tools, greatly improving the processing efficiency and processing accuracy.
4. High processing accuracy of linear guides
As a standard commodity, linear guides have entered a benign controllable range in terms of both material and processing methods. Therefore, most of the machine tools in many precision machining fields use high-precision linear guides as machine tool guides, which also greatly guarantees the processing accuracy of machine tools. The better domestic ones include Nanjing Technology, Hanjiang Linear Guides, Hiwin Linear Guides in Taiwan, Rexroth in Germany, THK Linear Guides in Japan, etc. These brands have greatly enriched and met the market demand for linear guides with various requirements.
5. Long service life of linear guides
Because the operation mode of linear guides is rolling friction, the steel balls in the slider drive the movement of the feed parts by rolling on the track. The friction force borne by this rolling friction is much smaller than that of hard rails, so whether it is transmission efficiency or service life, linear guides are much more ideal than hard rails.
6. Low maintenance cost of linear guides
In terms of maintenance cost and convenience of maintenance, linear guides have their natural advantages and convenience, because as a standard part, the replacement form of linear guides is the same as replacing a screw. Of course, there are some recovery adjustments in accuracy, but compared with hard rails, it is really convenient.
