But which tool is best?
We asked the professionals working for the Martin Bühler smithery. Based in Greater Stuttgart, this company has specialised in the production and installation of steel structures for rebuilds and shell construction. Girders with lengths of up to 8 m are adapted in the workshop so they can be fitted directly on site. Clean chamfers are absolutely essential. Benedikt Bühler, a metalworker foreman at Bühler, explains when bevelling machines and angle grinders are used.
Bevelling machines for long chamfers
“We often need longer chamfers on girders and this is when we use the FEIN bevelling machine. This makes chamfering a much less arduous task than working with an angle grinder. The cutting also produces a consistent result. Because the edges are cleanly deburred after machining, no rework is needed.”
Advantages:
- Fatigue-free working
- Chamfer for welded seam preparations in compliance with the relevant standards
Angle grinders for short, wide chamfers
“When working on components with large but relatively short chamfers, we prefer the FEIN angle grinder. Our experienced employees can then grind the angle evenly without a defined feed. Unlike a bevelling machine, the angle grinder also saves them from having to machine the component several times over.”
Advantages:
- Fast work progress
- No need for multiple machining
