SIASUN Intelligent Grinding And Polishing Solutions With Industrial Robots - Polishing Expert System (SR25A-20/1.80, SR12A-12/1.46)

A hand polisher can feel when a surface is right, but no one can keep that feel steady over a ten-hour shift, across hundreds of parts, with dust in the air. The SIASUN Intelligent Grinding And Polishing Solutions With Industrial Robots - Polishing Expert System (SR25A-20/1.80, SR12A-12/1.46) is built around that problem. It brings the robot, the tools, the fixtures, the control and the dust handling together as one finishing cell, so the result no longer depends on who is holding the tool that day.

Background

SIASUN and its robotics lineage

SIASUN is a robot maker whose industrial arms are sold in several payload classes, from small-payload models up to very heavy ones. Its catalog includes the SR25A, SR50A, SR210A and SR500A series, and the two models in this system, the SR25A-20/1.80 and the SR12A-12/1.46, come from the same family. You can browse the wider range in the Industrial Robots category, or look at the lighter models in the Small Payload category.

The polishing system is not simply an arm with a tool bolted to it. The Polishing Expert System is a package that encompasses the SIASUN robotic system, polishing tools, a fixture system, a control system and a water dust removal system. The aim is a one-stop solution that meets the user's needs comprehensively, so a plant does not have to match parts from several suppliers and hope they work together.

Positioning and key technology

Grinding and polishing are among the hardest jobs to automate, because the robot is not just moving through space. It is pressing against a part, absorbing repeated impacts and removing material as it goes. SIASUN approaches this with three ideas working together: a robot arm made for the task, a mature polishing software package, and control algorithms backed by precision sensors.

The software package was developed from years of experience in the polishing field. It offers high precision, efficiency, reliability and intelligence. Beneath it, advanced control algorithms and precision sensor technology work to polish product surfaces uniformly, improving surface smoothness and flatness. The system also adapts to different product shapes and sizes, which keeps the process precise and consistent when the part changes.

The arm itself has a bow-shaped design. That design gives it adaptability and flexibility when it has to follow complex curved surfaces. Its load design has been strengthened so it can withstand the repeated impact forces of polishing, which supports continuous, long-term, high-quality work. Its arm and wrist carry enhanced protection levels, and they resist polishing dust and liquid splashes.

What makes the Polishing Expert System different from a robot arm on its own?

A bare industrial arm can repeat a path very well, but a finishing job asks for more than a path. It needs tools that suit the surface, fixtures that hold the part the same way each time, a controller that manages how the tool meets the work, and a way to deal with the dust and liquid that polishing produces. Here those pieces are offered together as one system, so the buyer deals with one scope instead of five.

The software and sensing matter just as much. Because the control algorithms and precision sensors are built to keep polishing uniform, the cell is aimed at the surface quality of the finished part, not only at the accuracy of the arm. Smoothness and flatness are the targets.

The physical design also separates it from a general-purpose arm. The enhanced load design is meant for repeated impacts, and the protected arm and wrist are meant for a working environment full of polishing dust and liquid splashes. A compact, lightweight design improves space utilization and increases layout density, which is useful when floor space is limited and several cells have to sit side by side.

How do the SR25A-20/1.80 and the SR12A-12/1.46 differ?

The two versions share the same system concept, the same software approach and the same bow-shaped arm philosophy. The figures that separate them are repeat positioning accuracy: ±0.05mm for the SR25A-20/1.80 and ±0.03mm for the SR12A-12/1.46. The SR12A-12/1.46 is the version with a payload of 12 kg (26.5 lbs) and a reach of 1465mm.

For the SR25A-20/1.80, only the accuracy figure is given here, and we do not carry one version's numbers over to the other. If the tighter repeat accuracy matters most for your parts, the SR12A-12/1.46 is the one to discuss first. If your tooling or workpieces call for a larger robot, ask us about the SR25A-20/1.80. For a wider look at the SR25A family, see the SIASUN Industrial Robot Arm (SR25A-25/1.80), which is sold as a robot arm rather than a polishing system.

Who is the Polishing Expert System for?

Manufacturers that still finish parts by hand are the first group. Hand grinding and polishing are slow, physically demanding and hard to keep consistent, and a robotic cell brings repeatability to work that depends heavily on individual skill.

Plants with a mixed product range are the second. Because the system adapts to different product shapes and sizes, it suits shops where parts change from one batch to the next, rather than a single part run for years.

Workshops with limited floor space are the third. The compact, lightweight design is aimed at higher layout density, so more finishing capacity can be fitted into the same building.

Finally, integrators and engineering teams who want one supplier for the robot, tools, fixtures, control and dust removal will find the one-stop scope convenient. Teams that prefer to start with the tightest repeat accuracy should begin with the SR12A-12/1.46, while those who need a larger robot should ask us about the SR25A-20/1.80.

What is the Polishing Expert System used for?

1. Surface polishing: uniform polishing of product surfaces, with smoothness and flatness as the goals.
2. Grinding: robotic grinding work, with a load design strengthened for repeated impact forces.
3. Curved-surface finishing: the bow-shaped arm is made to follow complex curved surfaces with flexibility.
4. Mixed-part production: adapting the process to different product shapes and sizes while keeping it consistent.
5. Dusty, wet finishing areas: work where the arm and wrist face polishing dust and liquid splashes, supported by the water dust removal system.
6. Dense cell layouts: fitting finishing cells into tight floor plans thanks to the compact, lightweight design.

Summary

Hand finishing relies on touch, and touch is hard to repeat. The SIASUN Polishing Expert System replaces it with a coordinated cell: a robot with a bow-shaped arm, a strengthened load design, polishing software built on years of experience, and control and sensing aimed at uniform surfaces. The SR12A-12/1.46 offers ±0.03mm repeat positioning accuracy, 12 kg (26.5 lbs) payload and 1465mm reach. The SR25A-20/1.80 offers ±0.05mm repeat positioning accuracy. If consistent surface finishing is what your line is missing, this page is the starting point.
