Machine bed,gantry and parts are processed by high temperature tempering treatment and vibration failure treatment so they will be stable,no deformation even after many years. Pickling and phosphating protect the steel from rust, which also makes it more durable.
After the heat treatment and surface treatment, these parts are sent to the processing plant, where they are processed exactly twice.
We insist that third-party processing methods are not, because we understand how important it is that solid frameworks are always reliable for the accuracy and overall performance of the machines.
