Mapal New generation of countersinks achieve high accuracies, good surface finish
Germany – Mapal has developed a completely new generation of countersinks with significantly reduced axial forces, the supplier said.
It added that every machining process has latent potentials for boosting productivity.
Significant potential for improvement can be found even in seemingly secondary machining operations – as illustrated by the company's new generation of countersinks, Mapal said. The cutting edges of the countersinks have a noticeably unequal spacing. With this spacing, the axial force is said to be reduced by more than 50% compared with conventional countersinks.
The forces acting perpendicularly to the tool axis are also claimed to be reduced. Such optimised operating conditions create far less vibrations at the tool, allowing higher accuracies and better surface finishes to be achieved, Mapal said.
The precision of the countersink is claimed to lead to an immediately improved contact of bolted and riveted joints, eliminating settling of the joint under load after assembly. According to the supplier, the reduced load on the machine also increases the service life of the tools. Thanks to the smooth and stable running, the tools can also be operated with higher cutting data, resulting in considerable savings in time, Mapal said.
