HIWIN linear guide selection criteria
1. Use conditional set
Application of equipment
travel
Internal empty into the constraints
Running speed and acceleration
The requirements of precision
Use frequency
Rigid request of
Use environment
Load way
Request life
2. Choose series products
Employed by HG series: grinding machine, milling machines, lathes, drilling and comprehensive processing machines, discharge processor and honing bed, wire-cutting machine, precise measurement instrument, woodworking machinery, handling machine, transport devices.
EG: the industry automatic machine series, semiconductor machinery, laser engraver machines, packing machine.
MGN/MGW series: printer, robotic arm, electronic instruments, semiconductor equipment.
3. Choose precision grades
C, H, P, SP, UP rank depending on the equipment precision request
4. Assume the slider size and number
According to experience choose
Load conditions
And if a ball screw to cooperate to use, then use the linear guide specifications and screw diameter similar, such as screw diameter 35mm chooses for HG35 specifications
5. Calculation slider largest load
Refer to load calculation example calculation single slider maximum equivalent load
Confirm choose the linear guide static safety coefficient should exceed the static safety coefficient ShiYongBiao listed in the value
6. Select preloading
In accordance with the rigid requirements and mounting surface accuracy to choose
7. Confirm the rigid
Refer to the rigid table calculating deformation
Improve preloading, increasing choose size or sliding KuaiShu to improve rigidity
8. Calculation using life
By using speed, frequency calculation life distance requirements
In accordance with the life the formula to calculate the selected linear guide service life of distance
9. Lubrication choose
In accordance with the equipment selection of lubricant grease, lubricating oil demand can choose or special lubricant grease lubricated regularly injected or automatic injection
Linear guide choose finished. |
