Advantage and application scope
As the traditional
work-craft has some grudge between bushing with posts, and
the coefficient of friction is larger, now we have changed
the work-ways to steel-ball directly face to face guide bushing,
so the precision is machine, die machine, high precision machine
which need rotation and vertical motion.
