1. Selection of the shape and size of the section
For sections of the same shape, in the case of maintaining the same cross -sectional area, it is preferred to use the size of small wall thickness and small cross -section contour. The rigidity of the closed section is greater than the rigidity of the non -dense closed section. Opening holes in the wall will reduce the rigidity, and the rigidity of the convex band bending is recovered on the hole.

2. Selection and configuration of partitions and reinforcements
Reasonable layout of supporting partitions and ribs can increase the stiffness of the component. For vertical, horizontal and diagonal ribs, the effect of crossing ribs is the best; for some thin -walled components, the honeycomb -shaped ribs are better.
3. Improve the local rigidity of the component
The connection parts of the machine tool guide and brackets are mostly weak in local rigidity, but the connection method has a greater impact on the local rigidity.
4. Choose components of the welding structure
CNC processing center machine tool beds, pillars and other supporting parts are welded by steel plates and steel, which has a significant advantage of reducing weight and improving rigidity. The elastic modulus of the steel is about twice the cast iron. Welding with steel plates can make the component form a fully enclosed box structure, which is conducive to improving the rigidity of the component.
