Deburring economically



This is how deburring can be done economically

Anyone who skips deburring is saving money at the wrong end. This realization is becoming increasingly widespread in the industry. However, this does not mean that deburring costs have to be taken for granted. In this article, we show you where the key adjustments can be made.

Deburring as a process step is often enough unavoidable during sheet metal processing. Nevertheless, it can often be optimized economically. There are several ways to do this.

A deburring machine quickly repays itself

The first question to ask is whether a deburring machine is profitable. Compared to manual deburring, this question can be answered relatively quickly with a "yes": even with less than 500 hours spent on deburring per year, most scenarios are economically justifiable. This is because a deburring machine works much more efficiently than a person. It handles an estimated four times as many parts in the same amount of time as a person would by hand. This means a clear advantage in terms of profitability.

Profitability can be increased even further by automating the loading and unloading of the deburring machine. Depending on the configuration of the system, manual loading and unloading of the parts and sheets accounts for the largest proportion of the unit costs. A vision robot can now take over this task, even with changing part geometries and sizes. Skilled labor, which is already scarce, can devote itself to more important tasks instead of monotonous activities.

Deburring on both sides is more economical

It is also important to clarify whether a deburring machine that works on both sides is suitable for the task. It saves at least 30 percent of the time because the parts only have to pass through once. However, not all parts are suitable for a double-sided deburring machine. A single-sided deburring machine can also be the right choice for particularly uniform edge rounding.

The tools can also make a decisive contribution to increasing efficiency. This is especially true if an existing deburring machine is to be optimized. Reliable processing results can then be achieved with the right tool set, or you can increase the throughput of parts. The Wizard software from ARKU is a practical aid for tool selection, although it cannot be retrofitted. Based on just four parameters entered by the operator, it calculates the most suitable tool and the optimum throughput speed. This gives users high productivity with low tool wear.

Economical edge rounding increases economic efficiency

However, the wear of the processing tools in the deburring machine and the processing time can be influenced at the design stage. This can be done by rounding the edges as little as possible. This is because with a double radius of edge rounding, the material removal increases fourfold. So if you only round as much as necessary, you protect your tools and can have the parts and sheets processed more quickly.

It is not possible to generalize about the unit costs of deburring. This is because the shares of depreciation, labor, maintenance, spare parts and other factors vary depending on the machine configuration. However, there are trends that apply to most applications:

  • The higher productivity of the deburring machine compared to humans,
  • The savings with deburring machines that work double-sided compared to single-sided processing or
  • The relatively low proportion of tool costs with a high influence on quality and throughput.

All in all, it is worth taking a closer look at deburring processes. Often enough, there is still room for economic optimization.
