1, the whole bed is made of 45 # steel plate, 25mm steel plate and 16mm steel plate (50mm steel plate is the base of linear guide rail). after welding, the bed is annealed by 650 ° C stress relief to ensure no deformation in subsequent machining 
2, the use of gantry planer to machine the bed to ensure that the bed processing surface straightness, flatness 
3, the use of silver linear guide rail and TBI Ball Screw, to ensure the accuracy and reliability of the equipment, 
4, the installation of linear guide with self-collimator to test the accuracy of equipment, 6, linear guide and ball screw are using automatic oiling system lubrication;
