Classification by Guideway: Vertical machining centers can be classified into hardened guideways and linear guideways based on the type of guideways for each axis. Hardened guideways are suitable for heavy cutting, while linear guideways offer more sensitive movement.
Classification by Spindle Speed: Vertical machining centers with spindle speeds of 6000-15000 rpm are considered low-speed, while those above 18000 rpm are considered high-speed.
Classification by Structure: Vertical machining centers can be classified into C-type and gantry-type based on their bed structure.
