Property Characteristics | ||
1 | High Wearing Resistance: normally ten times of cast iron guide,good accuracy | |
2 | Low Friction: friction coefficient<0.04,only 1/3 of cast iron guide,reducing the driving-energy consumption | |
3 | No Creeping: moving steadily | |
4 | Good Shock-absorbing Ability: improving processing accuracy | |
5 | Good Lubrication |
