Deburring
Deburring is the removal of unwanted accumulations of material such as those resulting from stamping, milling or drilling.
Technology
The deburring is usually divided into 2 process steps. Removal of the (raised) primary burr and removal of the secondary burr and, if desired, the rounding of the edges. The primary burr, if the workpiece geometry permits, is usually removed with a sanding belt or aggressive abrasive disk or brushes.
Grinding often creates a secondary burr, as a part of the material to be machined is pushed over the edge. In the following step, the secondary burr is removed using Scotch brushes or other abrasive brushing tools. Accordingly, the original workpiece geometry is restored.
The workpiece is burr-free in this case, but still has sharp edges.
If required, edge rounding can be achieved in the same work step with the correct choice of brushes and parameters (eg: to rule out the risk of injury when handling the parts).
Often, the rounding of the edges is also required for technical reasons.
For example, to protect cables or laboratory gloves.
For surface-ground parts, eg: sintered metal parts, a defined edge rounding is often required. With this method, tolerances of up to 0.02mm can be achieved.
Applications
Punchings, stampings and laser cut parts, fineblankings, milled and drilled tubes and rods, sintered parts, milled parts, car rims. shop fittings, sealing plates, fittings, trim strips, clutch plates etc.
Materials
Stainless steel, steel, special alloys, copper, brass, aluminum, sinter metals,
Characteristic
Through the use of grinding stations and planetary stations and tools - which are selected according to the application - both deburring and edge rounding correspond exactly to the specifications required.
