Double-sided grinding and polishing machine

The workpiece is placed in the planetary wheel type workpiece holder, located between the upper plate and the lower grinding plate.

During the process, the outer ring, the central gear, the planetary wheel, and the lower plate rotate in the same direction, while the upper and lower plates rotate in opposite directions. This movement combines rotation and orbital translation of the workpiece, generating a uniform and non-repetitive grinding path.

The upper and lower plates can apply pressure and compensate for slight variations through a controlled flotation system, thus improving parallelism and flatness on both sides of the workpiece.

By processing the top and bottom faces simultaneously, the risk of bending or deformation of the part during the process is reduced.

9B Double-sided grinding and polishing machine

The SAINKO 9B double-sided grinding and polishing machine is specially designed for the fast grinding and polishing of metal parts.

It incorporates a drive by means of three motors, allowing the simultaneous movement of the upper plate, the lower plate and the sun wheel, while the inner toothed ring remains fixed.

The working pressure is generated by the weight of the upper plate itself and can be adjusted, reduced or increased, by reverse pneumatic pressure and control by an electric proportional valve.

The lifting stroke of the inner toothed ring reaches 70 mm, allowing the use of grinding wheels up to 50 mm thick. The process does not require abrasive fluid, offering an efficient and more environmentally friendly solution.

Field of application: Suitable for processing stainless steel, copper, aluminum and other metal products, such as suitcase hardware, high-end jewelry, 3C components and similar parts.

High-precision double-sided grinding machine

Mechanical characteristics:

• The machine incorporates independent drives for the upper plate, lower plate and central wheel, ensuring stable acceleration and deceleration.
• Its high rigidity structure and fixed column prevent vibrations during high-pressure processes, allowing for faster, more stable, and more precise work.
• It features a high-precision pressure control system with force feedback, which corrects the working pressure in real time.
• Equipped with a high-precision online measuring system, it allows the thickness error of the part to be controlled within 1 µm.
• The height of the central wheel is 70 mm, the lifting stroke of the toothed ring is 100 mm and it allows the installation of grinding wheels up to 50 mm thick.
• When the toothed ring and center wheel are manufactured in stainless steel for polishing applications, oxidation and its possible influence on the process outcome are avoided.
• The control interface is intuitive and allows flexible configuration of working parameters, as well as storing up to 100 process programs.
• In addition, it incorporates an advanced fault diagnosis function that helps the user to quickly identify and resolve issues.
