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
