In addition to comply with requirement of quality management system, PMI Group has been actively carried out "RoHS Green Environmental System" and environmentally friendly management system to conform to the regulation in order to reach a pollution-free workplace.

The PMI linear guideway is a design of rolling motion with a low friction coeffi cient, and the diff erence between dynamic and static friction is very small. Therefore, the stick-slip will not occur when submicron feeding is making. The frictional resistance of a linear guideway is only 1/20th to 1/40th of that in a slide guide. With a linear guideway, a well lubrication can be easily achieved by supplying grease through the grease nipple on carriage or utilizing a centralized oil pumping system, thus the frictional resistance is decreased and the accuracy could be maintained for long period.
