Automatic Router Bit Changer – ARC

The Zünd Automatic Router Bit Changer ARC includes a magazine that can accommodate eight router bits. In the standard configuration, six positions are available for regular bits and two for specialty bits, e.g. for v-grooving. If necessary, the magazine can be configured with two replacement holders so all eight slots accommodate standard bits. A cleaning station adjacent to the magazine ensures that each bit is cleaned with compressed air before being returned to its slot. During routing, the ARC is automatically lowered and sealed with a protective flap to keep out dust and debris. After each bit change, the integrated automatic tool initialization system ITI verifies the zero point for consistent, precise routing depths. The ARC also comes with a wear tracking feature so the operator knows at all times how long each bit has been in use. This effectively eliminates the risk of using a worn bit that will negatively impact routing quality. The ARC makes it possible for the Zünd cutter to route with very little operator intervention, making routing very efficient and cost-effective.

When it comes to finishing, the ever-increasing diversity of available rigid substrates poses particular challenges for Print Service Providers faced with demands for shorter runs, tight delivery times, and stringent quality requirements. With the automatic router bit changer ARC, Zünd introduce an automation feature that makes routing, polishing, and engraving efficient and cost-effective.

Fully integrated with Zünd Cut Center and Zünd Automatic Tool Initialization, the ARC consists of a freely configurable 8-bit magazine that completely automates the selection, clamping, initializing, and cleaning of router bits after each use. Compared to the manual processes involved in switching bits, automated bit changes are dramatically faster with greatly reduced setup times and virtually no potential for error. The advantages of the ARC are particularly noticeable with jobs that require a variety of routing, polishing, and engraving bits.

To ensure optimal quality control, the integrated automatic initialization system ITI verifies the zero point after each tool fitting for constant, precise routing depths. The ARC also comes with a wear tracking feature so the operator knows at all times how long each bit has been in use. This effectively eliminates the risk of using a worn bit that will negatively impact routing quality.

A significant advantage of Zünd's digital workflow automation is the option to operate the system with little or no operator intervention. With the automatic bit changer, the same is now true for routing. Even if they involve different operations, multiple routing jobs can now be laid out on the same sheet, which not only maximizes material usage but also allows the operator to attend to other tasks while the cutter is producing autonomously. The ARC takes care of changing bits according to the job and task at hand, making digital routing easier and more productive than ever.
