The guide shaft on the support is the basis of machine tool building. It is precisely the correctly selected guide shafts that are the components that ensure the correct kinematics of the CNC machine mechanism. The use of a support significantly increases the rigidity of the guides and almost completely eliminates their deflection.
For CNC machines and laser engravers, such shafts on a support are usually used: SA12, SA16, SA20, SA25, SA30 and others.
