Autonomous solution from Teqram simplifies precision grinding

In the world of steel construction, surface preparation is more than a preliminary step—it’s a defining factor in durability and corrosion resistance. While removing slag and burrs is routine, achieving a consistent edge radius of at least 1/16 inch remains a labor-intensive challenge. Traditionally, this process requires skill, endurance, and time. 

Now, an automation solutions provider has developed an intelligent robotic system that simplify automation. Teqram's EasyGrinder says its system simplifies precision grinding and seamlessly integrates with automated shot blasting.

Automation meets adaptability
Equipped with advanced 3D vision and an AI-driven controller, the EasyGrinder processes thermally cut steel workpieces without requiring programming or preloaded geometry data. This capability makes it an ideal solution for steel construction firms that frequently work with custom designs or small production runs. By adapting on the fly to different workpieces, the system ensures a level of precision and efficiency that manual methods struggle to match.

Versatile approach to grinding
What sets the EasyGrinder apart is its flexible tooling system, which adjusts to the specific needs of each component. Slag removal is handled with a chisel, while edge rounding is achieved using a lamella disc or a pencil grinder, depending on the shape of the workpiece. For cutting edges, an angle grinder is used, while countersinking tools refine drilled holes. Even intricate lead-ins or starting points are efficiently removed. This adaptability guarantees optimal surface preparation, regardless of complexity.

No programming, no hassle
One of the standout features of the EasyGrinder is its ability to operate without programming or preloaded geometry data. Using real-time 3D vision, the system detects the geometry of each workpiece and determines the best processing strategy. 

For instance, when creating a 3/32-inch radius, the system performs the operation in three controlled steps with a flap disc, ensuring compliance with AISC 360 and AWS D1.1 standards for structural steel fabrication. The operator’s role is simple: place the workpieces on pallets within the robot cell and select the desired processing quality from pre-set options.

Why surface preparation matters
Strict standards such as SSPC-SP and NACE define the levels of surface preparation required for effective corrosion protection. These standards, in conjunction with AISC 360 and AWS D1.1, emphasize that proper surface treatment directly affects the longevity of protective coatings. By adhering to ASTM D3623 and ASTM G101 classifications for environmental exposure, steel structures gain enhanced resistance to harsh conditions, ensuring long-term performance and safety.

Seamless integration with shot blasting
Efficiency in steel fabrication doesn’t end with grinding. The EasyGrinder is designed to work in tandem with automated shot blasting systems, streamlining the entire surface preparation workflow. Once the grinding process is complete, the robot places workpieces into a rotary table shot blasting machine, where both sides are treated. Thanks to an automated turning system, manual intervention is minimized, while double-blasted edges improve coating adhesion and eliminate shadowing effects. Additionally, rotary table shot blasting consumes significantly less energy than traditional roller conveyor systems, leading to substantial cost savings.

Addressing the skilled labor shortage
The steel industry, like many others, faces an increasing shortage of skilled workers. Manual grinding and blasting are not only physically demanding but also prone to inconsistencies. By automating these labor-intensive tasks, the EasyGrinder allows experienced professionals to focus on higher-value work, while ensuring reliable, repeatable quality in surface preparation.

Efficiency in steel fabrication
With its combination of precision, adaptability, and ease of use, the EasyGrinder represents a significant leap forward in steel processing. By reducing reliance on manual labor, enhancing consistency, and integrating seamlessly into existing workflows, it offers a smarter, more efficient way to meet the demands of modern fabrication.
