Burrs, requiring subsequent deburring, are often inevitable when working in tough plastic materials. We try to machine all edges that are accessible. It is important during preparation to state what level of deburring is required.
It is often stated as general text on drawings, ”All edges bevelled”. Bevelling may in many cases cost as much as the machine processing.
In the medical technology area, however, burrs may constitute a risk for patients and it is then important that all items are examined under high magnification (see picture).
