SIASUN Grinding robotic solution (Grinding robotic solution)

Grinding is the job a workshop most wants to automate and least trusts a robot with. A rigid arm following a fixed path will gouge a casting where it bulges and skip a weld seam where it dips, whereas a skilled operator feels the surface and eases off. The SIASUN Grinding robotic solution is built around that difference: SR series robots paired with force-controlled grinding tools, a dedicated polishing process package and offline programming. The aim is a robot that presses with the judgement of a person, not merely the repeatability of a machine.

Robots Europa, based in Dublin, supplies the SIASUN Grinding robotic solution to customers across the EU and the DACH region. Robots Europa prepares each quotation around the kit system that matches your grinding scenario and coordinates delivery, documentation and after-sales support for your site.

Background

SIASUN and the SR series

SIASUN is a Chinese robotics and automation manufacturer whose portfolio spans industrial arms, collaborative robots and complete process solutions for welding, handling and surface finishing. Rather than selling an arm and leaving the integrator to assemble the rest, SIASUN packages its SR series industrial robots with process-specific tooling and software, so that a grinding cell arrives as a coherent system. The grinding solution sits alongside the company's welding solutions within its wider range of Industrial Robots, and follows the same logic: one robot family, configured for a particular process.

An integrated kit rather than a loose collection of parts

SIASUN describes the grinding offer as a kit system based on an integrated intelligent design. The kits cover lightweight, medium and heavy grinding as well as surface polishing, and the SR series robots are equipped with a series of grinding tools that can be freely configured according to the grinding scene. At the core sits SIASUN's own intelligent grinding and polishing process software package, developed under the company's independent intellectual property rights, which gives the system its characteristics of high rigidity and high precision. A dedicated polishing process package improves workmanship, and a safety module provides dual protection for the product and for personnel.

What separates the three SIASUN grinding kits?

The three kit systems share the same SR series robot family, the same process software and the same offline programming tools. What separates them is the tool at the end of the arm and the work it is meant to do.

The SR25A-25/1.80 kit system carries an independent three-head force-controlled tool and is assigned to surface polishing. Several heads working together suit broad surfaces where an even finish matters more than rapid stock removal, which is why this kit is the natural choice when appearance is the deliverable.

The SR25A-35/1.80 kit system uses a single-head force-controlled tool for light-duty applications. A single head is the most straightforward arrangement for deburring, edge breaking and light finishing, where the tool must reach into features and follow contours closely.

The SR50A-70/2.15 kit system moves to a dual-head force-controlled tool and to medium- to heavy-duty applications. This is the kit for parts that need genuine material removal, such as weld seams, cast surfaces and heavier fabrications, where the process demands more from the robot and the tooling alike.

Choosing between them therefore starts with the part and the finish required, not with the robot. Robots Europa will match the kit to your component during the quotation.

How does force control change robotic grinding?

Conventional robot programming is positional: the arm visits a sequence of points, regardless of what it meets on the way. In grinding, that is a weakness, because real parts vary. Castings differ from one batch to the next, weld beads are never quite identical, and fixtures introduce small offsets. A purely positional robot either removes too much material or too little.

Every SIASUN grinding kit uses a force-controlled tool. Instead of holding a path rigidly, the tool regulates the contact between abrasive and workpiece, which is what allows a consistent finish across parts that are not perfectly identical. Combined with the high rigidity and high precision of the SIASUN process software, the result is a cell that behaves more like an experienced finisher than a copying machine.

Programming is the other half of the argument. Grinding paths are notoriously time-consuming to teach by hand, which has kept many smaller batches manual. SIASUN's offline programming software and fast programming plug-in double the efficiency of programming, so new parts can be prepared away from the cell while production continues. Easy deployment, high integration and flexible configuration complete the picture: the kit is designed to be put to work, not merely installed.

Who is the SIASUN Grinding robotic solution for?

The solution suits manufacturers for whom manual grinding has become a bottleneck, a quality risk or a health and safety concern. Foundries and casting finishers dealing with gates, risers and parting lines will look first at the SR50A-70/2.15 kit system, whose dual-head tool is aimed at medium- to heavy-duty work.

Fabricators and welding shops that need to dress seams after welding fall into the same segment, and may already be considering robotic welding; the grinding cell completes the chain downstream.

Machining and component suppliers whose main task is deburring and light finishing are better served by the SR25A-35/1.80 kit system and its single-head tool, which concentrates on light-duty applications.

Producers of visible surfaces, such as housings, panels, fittings and decorative components, where the polish is what the customer sees, should consider the SR25A-25/1.80 kit system, with its independent three-head tool for surface polishing.

Finally, system integrators across Europe who build finishing cells for their own clients will value an integrated kit with its own process software, offline programming and a safety module already part of the package.

What is the SIASUN Grinding robotic solution used for?

1. Surface polishing: producing an even, consistent finish on broad surfaces with the three-head force-controlled tool.
2. Deburring: removing burrs and sharp edges from machined components in light-duty work.
3. Weld seam grinding: dressing weld beads after fabrication with force-controlled contact rather than a fixed path.
4. Casting fettling: removing excess material from cast parts in medium- to heavy-duty applications.
5. Edge finishing: breaking and smoothing edges where a single head can follow contours closely.
6. Replacing manual finishing stations: moving operators away from dust, vibration and noise while keeping workmanship consistent.

Summary

The case against automating grinding has always been that a robot cannot feel the part. The SIASUN Grinding robotic solution answers that objection with force-controlled tooling on every kit, process software developed by SIASUN itself, offline programming that doubles programming efficiency and a safety module that protects both product and personnel. Three kit systems divide the work clearly, from surface polishing through light-duty finishing to medium- and heavy-duty grinding, so the choice follows the part rather than the catalogue. For manufacturers and integrators in the EU and the DACH region who want to bring that judgement to their finishing line with Robots Europa, this page is the starting point.
