Single-Side vs. Double-Side Deburring Machines: A Comparative Study

After laser cutting, the parts cannot enter the assembly stage immediately. Therefore, a deburring machine is needed to remove the burrs produced during the cutting process.

Other processes, such as flame or plasma cutting, often leave coarse burrs and slag on the surface of sheet metal parts (see Fig. 1).

These “die-hard” burrs can impede efficient processing in subsequent stages.

Nowadays, modern automatic deburring machines can efficiently remove burrs, round edges and corners, and ultimately present clean and polished sheet metal parts. This greatly reduces scrap rates and production costs, and enhances product competitiveness by showcasing their advantages.

Advantages of double side deburring machine

The efficiency of a deburring machine that can process both sides is doubled, and the workpiece does not need to be turned over. It only needs to go through the deburring machine once to achieve deburring on both sides (see Fig. 2).

Compared to a single-sided deburring machine, the double-sided deburring machine saves over 50% of the time and eliminates redundant workpiece movement and loading and unloading time. This machine can save between 40-80 euros per hour, making it a wise economic choice.

Even if the machine is only used for a few hours per week, it can still provide a substantial return on investment.

The double-sided deburring machine is also suitable for sheet metal parts that only require processing on one side. It saves time on pre-sorting or turning the workpiece, especially when dealing with larger workpieces or heavy flame cutting parts, which can be time-consuming and pose high risk factors.

However, depending on the manufacturing process, companies can also opt to increase the loading and unloading process to compensate for the limitations of a single-sided deburring machine. By doing so, they can achieve a better return on investment and gain a competitive advantage by producing superior products.

Advantages of single side deburring machine

Single-sided deburring machines still hold value in certain application fields.

Unlike double-sided deburring machines, single-sided deburring machines come equipped with a vacuum table that offers support for smaller parts to be safely repaired and processed. On the other hand, with the double-sided deburring machine, smaller parts tend to fall from the working unit’s seam.

This is why many laser OEM enterprises prefer single-sided deburring machines, especially when dealing with a large number of different-sized parts.

If the single-sided deburring machine is equipped with a universal rotary brush, it can fillet the sheet metal parts placed on the vacuum table. The universal rotary brush moves to the sheet metal parts from various directions to produce the best rounding effect on the material’s inner and outer contour. The processing effect is uniform, regardless of the workpiece’s shape and direction, and the unique rounding radian can reach 2.0 mm.

In addition to deburring and filleting, the last bright process of single-sided processing equipment is surface roughness treatment (Fig. 3).

To achieve this, the equipment is equipped with a separate surface treatment unit.

In summary, single-sided deburring equipment can play a crucial role in certain fields. It is not only suitable for processing small parts but also suitable for large and wide sheet metal parts.

For instance, in the processing of laser or plasma cutting parts, it is necessary to take into account unique functions like uniform rounding. In contrast, the single-sided deburring machine is more flexible and easier to meet the requirements of deburring, filleting, and other surface treatments of sheet metal parts.

How to choose deburring machine

The key factors to consider when choosing between a single-sided or double-sided deburring machine are the range of parts and the production process.

A single-sided deburring machine can cover a wider range of workpieces and produce a more uniform fillet effect. However, it takes more time and may increase the cost of material processing.

Using a double-sided deburring machine can improve production and processing efficiency, but it is less flexible in processing various parts.

When selecting a model, it is not always necessary to look for a device that can cover all parts. If a deburring machine can cover 80% of the material range, it can be considered sufficient to meet the demand and achieve the capacity target.

If a company needs to handle some special workpieces, they can choose to outsource deburring work to supplement their capabilities.

If necessary, the company can also calculate whether it is more cost-effective to purchase two deburring machines: a double-sided deburring machine to improve the efficiency of processing large quantities of workpieces, and a single-sided deburring machine to process small parts, which is more flexible and efficient.

Moreover, having two sets of the most advanced deburring equipment and perfectly combining them can be an excellent choice for enterprise production.
