Technical Description
Technical description:
The ring rail path need to bear both thousands of tons of static pressure and working dynamic alternating pressure, with high requirement
on manufacturing process and materials.
Large diameter of ring rail with high precision and assemble accuracy.
Their counterparts at the height difference and the difference between left and right positions
The height difference at their counterparts of each rails is less than 1mm
The difference between the left and right location of each piece of ring rail, less than 1mm
The surface on the bottom corresponds to the horizontal datum level, within the 300mm length range, the gap is less than 0.5mm.
Advantage:
1. High strength material
2. Strength toughness
3. High machining roughness and assemble accuracy
4. Longer lifetime, or longer service lifetime.
