The machines used to remove sheet metal burrs come in different constructions and configurations. However, making the right choice between grinding brush and grinding roller, single or double sided machining is not an easy task, especially when there are more models to choose from. This article will help you find the Flat bar deburring machine that meets your needs.

There are many methods of deburring, and they all have their own advantages. Because burrs on a part are diverse, there are other factors to consider, such as requirements for productivity, flexibility or uniformity of edge chamfers. Therefore, when looking for the right Flat bar deburring machine, you must ask yourself the following questions in a certain order.

Question 1: What is to be removed?

The core of deburring process must be burrs. However, we need to carefully observe the burr condition before processing. In thermal cutting processes (such as flame cutting or laser cutting), so-called slag is produced, and the thicker the plate, the more slag: slag is not a problem for thin plates, but it is a big problem for thick plates, slag is deposited by metal oxides, with different properties than the burr itself, and the burr and sheet metal parts themselves are made of the same substrate. In addition, the slag is relatively soft and sometimes does not adhere very firmly to the sheet metal. At this time, we do not recommend the use of sanding to remove the slag, because the sanding sandpaper will soon be blocked by abrasive debris. In contrast, the slag can be easily knocked out using a steel hammer. The steel hammer device must be installed in front of the deburring device to ensure the smooth operation of the two processing processes without interference.

Question 2: How big are burrs?

When the burr is firmly attached to the sheet metal, you need to use a tool to remove it. These tools must also match the size of the burr: strong enough to remove burrs, but fine enough not to damage sheet metal parts. The size of a burr depends largely on the thickness of the material.

In general, large burrs need to be removed with a sand roller, while a grinding brush is more suitable for removing small burrs, secondary burrs and chamfering treatments. Flat bar deburring machine is designed according to these specific processing needs, using different principles.

Question 3: How big is the sheet metal part?

This problem is very important for choosing a Flat bar deburring machine with single or double-sided machining. Double-sided processing equipment requires sheet metal parts must meet the minimum size requirements, otherwise the parts are easy to fall from between the grinding brush units. The single-sided Flat bar deburring machine is equipped with support devices such as vacuum belts, which can hold small parts as small as coins.

If the size of the part allows, a double-sided Flat bar deburring machine is usually a better choice. Its work efficiency is much higher than that of single-sided processing machines: the parts only need to pass once to complete the processing of both sides, without flipping and replacing, which is very labor-saving and time-saving. Even if the burr is only on one side of the part, the use of two-sided deburring equipment is beneficial and harmless. This allows you to place the sheet metal at will, regardless of the orientation of the burr surface.

Question 4: How important are the rounded corners?

The Flat bar deburring machine not only removes burrs, but also fillets the edges of parts. If you need a particularly uniform edge chamfering effect, you can also choose an efficient universal roller brush for processing. This roller brush will touch the surface of the part from different directions for processing. The workpiece in the chamfering unit must be firmly placed flat on top of, for example, the vacuum belt to ensure a uniform chamfering effect. Note that only a single-sided Flat bar deburring machine can provide you with this process.

Fifth question: How high are the surface requirements for finishing?

The Flat bar deburring machine handles the edges of the sheet metal, but it also inevitably leaves a polished grain on the surface of the part. Some customers have higher requirements for the surface of the parts, then you also have two options: use your own finishing machine to finish the surface of the parts; Or finish the parts with the polishing unit that comes with the Flat bar deburring machine. However, in the second scheme, only a single-sided Flat bar deburring machine can do this.

Final question: Which is the best Flat bar deburring machine out there?

To answer this question, we must consider one decisive factor: the range of parts to be machined. If one machine cannot handle all the parts, we give you two suggestions: buy a second Flat bar deburring machine; Or outsource some parts to processing service providers. Either option is more attractive than tedious and time-consuming manual deburring.
