Breaking sharp edges and deburring
Some machining processes often create rough edges and ridges known as burrs. These not only pose a risk of injury, but also influence the dimensional tolerance of the workpieces. For these reasons, the burrs must be removed.
There are various methods of doing this such as grinding, milling or barrel finishing. It is very time-consuming to remove burrs with a manual grinding machine. Only small workpieces can be processed by barrel finishing. For this reason we have invested in a modern Timesavers grinding machine, with which we can process workpieces up to a width of 1600 mm.
Timesavers 42 RB
- 8 grinding brushes
- Operating width: 1600 mm
- Workpieces from 50 x 50 mm
- Material thickness: 1 – 100 mm
- Processing of various materials including aluminium, steel and stainless steel
- Grinding of flat and formed parts
- Deburring, radiusing and breaking edges with one machine
Breaking edges is a machining process in which the edges of workpieces are given a fillet radius. All safety and quality specifications are met by the production of these small uniform radii. Surface treatments are easier to carry out on rounded corners and paint adhesion is significantly improved. This machining process also plays an important part in the production of load-bearing structures in accordance with EN 1090.
What are the advantages of breaking edges?
Our Timesavers grinding machine has 8 large rotating brushes. This enables us to produce 2 mm radii on all workpiece edges in consistent quality, regardless of their orientation. To produce these radii manually would be enormously time-consuming and thus very expensive. Grinding not only saves time, but also offers the following advantages:
- Small constant radii of +/- 2 mm
- Holes and recesses are deburred in the same work stage
- The adhesion of paints and coatings is improved on the edges
- Safe handling and assembly of parts without a risk of injury from sharp edges
5 good reasons for deburring
Burrs, sharp edges and scale usually occur with thermal processing methods. In most cases these are undesirable and have to be removed for the following reasons:
|1||Appearance||Burrs are often regarded as unsightly, especially in visible places.|
|2||Functional||Burrs can be detrimental to the use of the product or make it completely unusable.|
|3||Ease of assembly||The workpiece will not fit the assembly or the burrs prevent an accurate installation.|
|4||Further processing||The burrs prevent correct clamping or the workpieces will not lie flat on the machine bench.|
|5||Safety||Burrs and sharp edges constitute a hazard and can cause laceration injuries.|
