A metalworking company from the region of Utrecht used Beveltools for a large project. For one particular client, they had to produce different steel parts for electricity pylons. These electricity pylons, with a height of 180 to 245 ft (55 to 75 m), were recently fitted in several areas, including Achterhoek (The Netherlands).
The manager explains: “For this client we delivered the steel parts for the electricity pylons. These included a large number of connection rings, lifting eyes, bulkheads, brackets and attachment points used for the pylons.” Because these are load-bearing galvanised steel constructions, all parts must carry CE certification in accordance with NEN-EN 1090. This norm states the technical specifications to which the steel end products must adhere. Part of this norm stipulates that edges must be rounded with a minimum radius of 2 mm to obtain a greater bonding surface for coating.
“The connection rings must all be rounded in accordance with the EN 1090 norm. We chose to do this with radius 3 to achieve a better finish. The largest connection ring had a diameter of 8.3 ft (2.5 m), which makes a lot of metres to round off. I looked for a system with which I could quickly achieve radius 3 at a low cost. We didn’t have much experience with rounding, but for this project we delved into it and we decided to purchase a machine,” says the manager. The machine had to be easy to handle and control, and not too expensive to use so that it would also make sense for smaller projects. Initially, the company had gone for a system with inserts.
However, they did not meet expectations. The service life promised was not achieved and the inserts had to be exchanged much too often. “Alternating the inserts takes an incredible amount of time, plus they are fragile so they broke all too often even before we’d used them for all cutting edges. The work took much longer and cost much more than I’d anticipated. Then I contacted Beveltools and immediately switched to this system, especially because of the single bevel head. The steel bevel heads by Beveltools lasted 2 to 2.5 times longer in our case than a set of inserts. When Beveltools showed us the Premium bevel head, we immediately started to use it. With just one Premium bevel head we could round off over 660 ft (200 m). That is four times more than with a set of inserts!”
For the metalworking company it is a huge advantage that the bevel heads are made up of one piece. You can swap the bevel head in the blink of an eye and because it has many cutting edges, machining goes really smoothly. “With Beveltools we were able to finish our work before the deadline and at an advantageous cost. Our client was delighted with the results.”
