1. Ball screw and linear guide positioning accuracy is high
When using linear guide, because the friction of linear guide is rolling friction, not only the friction coefficient is reduced to 1/50 of sliding guide, the difference between dynamic friction and static friction also becomes very small. Therefore, when the machine runs, there is no slippage phenomenon, can reach μm level of positioning accuracy.
2. Ball screw and linear guide wear less to maintain accuracy for a long time
Conservative sliding guide, will be caused by the counter-current effect of the platform movement accuracy is poor, and movement when the lubrication is not sufficient, resulting in the running track contact surface wear, will seriously affect the accuracy. The wear of rolling guide is very small, so the machine can maintain the accuracy for a long time.
3. Ball screw and linear guide for high-speed movement and significantly reduce the machine required to drive horsepower
Because the linear guide moves with very little friction, only a small amount of power is needed to make the machine bed run, especially the way the machine works for regular round-trip operation, more obviously reduce the power loss of the machine. And the heat generated by friction is very small, so it can be applied to high-speed operation.
4. Ball screw and linear guide can simultaneously accept the load of the up and down and left and right direction
Due to the special bundle structure design of linear guide, it can accept the load of up and down and left and right direction at the same time, the lateral load that sliding guide can bear in the direction of parallel contact surface is lighter, which is easy to cause poor machine running accuracy.
5. Ball screw and linear guide assembly is easy and interchangeable
Assembly as long as milling or grinding bed guide assembly surface, and the guide, slider are fixed to a specific torque on the machine, that can reproduce the processing of high precision. The conservative sliding guide, it is necessary to run the track to shovel, both laborious and time-consuming, once the machine precision is poor, and then it is necessary to shovel once again. The linear guide has interchangeability, can be replaced respectively slider or guide or even linear guide group, the machine can regain the high precision guide.
High-speed processing (ball screw and linear guide) generally use high milling speed and fast multiple tool walking to improve efficiency. High-speed machining relative to conventional machining has outstanding advantages: high productivity, smooth work, processing surface quality is very high, without other surface treatment processes, conducive to the processing of thin-walled parts and high strength, high hardness brittle materials. It can shorten the delivery time, reduce the number of equipment and workshop area, and reduce the number of workers. Despite the initial increase in equipment investment costs, the overall benefits of the high-speed milling process have been significantly improved.
