uPVC profile cutting machine is major and essential equipment for manufacturing uPVC windows and doors. Cutting is the beginning of making uPVC windows, and one of most important manufacturing procedures in the whole window manufacturing process. The cutting accuracy (such as accuracy error of cutting length, accuracy error of cutting angle) will affect the welding accuracy and welding strength of uPVC windows, and then affect the size accuracy and angle accuracy of finished uPVC windows. STONE Window Machinery guarantees the cutting quality of the uPVC profile cutting machine through use of high quality hard-alloy saw blades, high accuracy liner bearing motional pairs and headstock, and other high quality machine components, and through our strict quality control system. uPVC profile cutting machines mainly includes double mitre saw, V-notch saw, glazing bead saw, and so on.
