Machining center rail form and its characteristics?
Hard track is "a smooth plane in another smooth plane to move," between the two sides is sliding friction, friction is large, so the movement speed is slower.But the hard track contact area is much larger than the line,
Can not afford too heavy weight, commonly used in micro or small equipment.
Simply said the line in the form of "the ball in the track to move." Is a rolling friction, friction is small, so the installation of rails table movement faster.But due to the ball bearing capacity is limited, so the line
So hard-track load-bearing capacity is several times the line. Commonly used in large and medium-sized or giant processing center.
