CNC Automatic Sink Rolling Seam Welding Machine with Mitsubishi Control System utilizes the seam welding principle to replace the spot welding electrode with circle welding wheel. Medium frequency inverter power supply system is adopted for ensuring good welding quality. Use professional PLC control system from Japan Mitsubishi brand. As long as inputting the data like coordinate data of sink position, welding current, etc., then the welding track will automatically finish welding product within the preset procedure after starting. Operator only need to put the work piece onto certain place and then take it away when finishing welding. 
 
Adopt medium frequency inverter power source of welding and large flat platform of locating pattern. 
Use the servo motor to drive X axis (locating mould) and Y axis (welding electrode) to operate under the preset procedure of PLC data. 
It could store 15 sets of welding models at most (be able to store 15 sets of welding position and welding current of product). 
According to the stored position of welding spot, the welding product will be located inside the mould and moves horizontally along the X direction and the moving area should be no more than 1200mm. 
The welding electrode will be designed to move vertically along the Y direction and the moving area should be no more than 620mm. The welding electrode moves from top to bottom within 250mm along the axle Z direction and be able to conduct 360° of rotation under the control of servo motor so it is suitable for welding different angles of products
