Now that the basics have been explained, let’s get specific. Here you will get a glimpse of our day-to-day operation: Process and project planning.
It is not possible to exactly define the mechanical capabilities for removing a burr. The following factors significantly affect the feasibility of a mechanical deburring process:
- Tool inserts and materials that can be used
- Component shapes and tolerances as well as accessibility
- The required deburring result
- Cycle times
- The experience of the programmer who maps the process onto the workpiece.
For example, in theory a deburring process can be implemented very easily because the contours are accessible and the deburring requirements achievable. In reality, however, the optimal cutting materials may not be used but alternative cutting materials cannot always achieve the desired deburring result.
Other examples are cast workpieces. Depending on the age of the mould, the component can be subject to large fluctuations within a tolerance range. If the mould is new, the tolerances are much smaller and a deburring process for these workpieces can be mapped much more easily. Casting variations increase along with the age of the mould. The process has to be adapted accordingly so that the same quality can be delivered across all stages of the mould.
Depending on their accessibility as well as the tool that is being used, drilled holes can be machined up to a certain degree. Generally, however, a mechanical deburring process always leaves behind a root burr. It can be removed in combination with a chemical or thermal deburring process. Depending on their accessibility, undercuts can partially be machined with special tools.
External contours can usually be machined without limitations. Generally, the only thing that has to be taken into account here is the tension of the component during machining.
