Product Description

The CNC 3 Axis Control Stainless Steel Kitchen Sink Seam Welding Machine represents a cutting-edge welding method that surpasses traditional spot welding techniques. It employs a pair of roller electrodes in lieu of cylindrical electrodes, allowing the workpiece to move seamlessly between the rollers. This dynamic process results in a sealed weld with overlapping molten cores, effectively bonding the workpiece together.

This state-of-the-art machine features a medium-frequency inverter power source for welding and utilizes a large flat platform for precise locating. The X axis (locating mold) and Y axis (welding electrode) are driven by servo motors, meticulously following the preset procedures stored in the PLC data. As per the welding spot's stored position, the welding product is precisely located within the mold, moving horizontally along the X direction. Simultaneously, the welding electrode moves vertically along the Y direction. What sets this machine apart is the welding electrode's ability to perform a 360° rotation under the control of a servo motor, making it adaptable for welding different angles of products.

Designed for versatility, this machine is particularly well-suited for welding sinks within the dimensions of 1600x700x300mm, and it can be further customized to meet specific requirements.

Japan Mitsubishi CNC Control System Adopts three sets of Japan Mitsubishi servo motor to control axis X (movement of sink mould), axis Y (vertical movement of welding wheel), and axis A (360° rotation of welding wheel).

Auto Moving Welding Table Specially designed electrode large table, more stable conductivity, to ensure the effectiveness of welding.

Big Copper Flat Table Electrode and Fixture We will design the fixture according to the design of your sink bowl. Different sizes may require different fixtures. Be able to do welding of single bowl, double-bowl, or three-bowl product

Welding electrode Synchronized operation of welding electrodes and Moving Welding Table, Automatic welding of sink, Uniform and beautiful welding seam.

CNC Sink Edges Grinding and Polishing Machine

This is the special designed machine for grinding and polishing the seam after welding. Normally customer will choose to buy these two machines together so as to complete the production of kitchen sink. This CNC sink grinding special machine utilizes abrasive belt polishing principle. The abrasive belt is driven by electric motor to conduct polishing on the edge of the welded sink. There are two processes for polishing. Firstly, use the coarse abrasive belt to grind the redundant cutting edge and the projection welding spots. Then use the fine abrasive belt to conduct polishing treatment. After these two processes can meet the requirement of sink grinding and polishing treatment.

Special Design Grinding Belt	Auto Moving Table and Fixture Structure
Brown belt (fine abrasive belt) DEERFOS RA631 150# Blue belt (coarse abrasive belt) 577F P80Y The movement and control system will be the same as the sink seam welding machine	For sink bowl within 1500mm, we can choose to use fixed table with adjustable fixture. For sink bowl over the limit, we can design the automatic moving feeder to achieve full automatic grinding and polishing.

This CNC sink grinding special machine utilizes abrasive belt polishing principle. The abrasive belt is driven by electric motor to conduct polishing on the edge of the welded sink. There are two processes for polishing. Firstly, use the coarse abrasive belt to grind the redundant cutting edge and the projection welding spots. Then use the fine abrasive belt to conduct polishing treatment. After these two processes can meet the requirement of sink grinding and polishing treatment. It is designed to use Mitsubishi professional automatic control system. You only need to input the coordinate data of the product and start the machine, the abrasive belt of the machine will conduct grinding and polishing automatically within the track of preset program. The worker only needs to put and take out the sink.

The product will be fixed on the locating mould. The servo motor will drive the X and Y axle to run within the preset data of program. The machine could store 15 types of grinding models. The grinding wheel will move along with X direction and the max moving range is 1220mm while the max moving range of Y direction is 620mm. The Z axle can conduct moving up and down within the range of max 250mm while the A axle can conduct 360ºrotating under the control of servo motor. This machine is suitable for different directions of product.
