Fabrication technology has progressed enormously over the last decade. The new breed of Fiber Laser is more powerful and faster than ever. Plasma cutting is ubiquitous, CNC Punch Presses are now doing more forming, and Waterjet Cutting has become mainstream.

However, all of these systems of cutting create either burrs, dross or square sharp edges.

There are two types of burrs the first is mechanical as a result of punching, sawing, drilling etc. Adequately sharpened tools and correct clearances can minimise these, but quite often the burr can not be eliminated. The second is thermal, commonly referred to as slag or dross. The proper fuel mixture, cutting speed, replacement of tips and optimising other parameters can substantially reduce the burr, but again it is often challenging to eliminate. We also find that sometimes with modern laser cutting when the cut is close to perfect and the burr is almost unnoticeable, we have a slightly different problem where the edge is so square and sharp that it becomes dangerous to handle.

Before you choose a deburring or finishing machine, you need to define the desired edges your parts require, and this is not so easy because there is no real Australian standard in terms of deburring. Usually, drawings say “burr-free” but what level of deburring does this require?

Years ago all our deburring machines used abrasive belts, the problem with that was it tended to knock the burrs down and often created a grain finish but didn’t remove necessarily remove the burrs properly or round the edges. It made the edges sharper.

Today we use a mixture of brush heads available in both wire and abrasive strips, abrasive belts or drums, cross belts with abrasive strips or cylindrical brushes. Each system achieves a different outcome.

If you have a single issue, you need to resolve, you can invest in a straightforward machine that uses just one system, but we find it is more common that most fabricators have varied requirements. So they usually would be better investing in a finishing machine that has multiple systems that can finish the part in one pass. If there is a part with a single issue, for example rounding edges but not removing the dross, then the operator can activate or deactivate any individual system via the Touch Screen Control.

We work closely with Gecam in Italy for deburring and finishing projects.

If you would like to send us your problematic parts, we can send them to Italy where they will run your sample through various systems, video the test and send us back the samples for your inspection.
