Onsrud posted this technical article titled “Router Bits for Sign Industry” on their website, we’ve summarized the findings but you can read the full article here: http://www.onsrud.com/plusdocs/Doc/index.html?model.code=TECH016
Signs and the information they express have become an integral part of everyone’s daily life. Companies of all sizes serve this massive market, however they all have the common problems associated with routing the materials common to the industry. These common materials (wood, aluminum, foam & plastic) all have different cutting characteristics and no individual tool can solve all routing problems.
Plastics can be placed into two general categories, flexible and rigid. Flexible plastic is usually best cut with a sing or double edge “O” tools. In terms of rigid plastics double edge straight “V” flute tools, spiral “O” flues with hard plastic geometry and two and three flute finishers are recommended.
Recently, there have been several new styles of specialty tools developed to improve finishes with faster cycle times without tool changes and or advanced programming techniques. In this blog we highlight two of these tools and show how they will be advantageous to the sign industry.
The first, the solid carbide bottom surfacing tool, was developed to provide smooth bottom surface in lettering and pocket applications. Most router tools are designed to plunge and rout with the emphasis on the side geometry rather than the point. Consequently, the point end would always leave swirl marks, which required a secondary operation to remove the swirls. The new tool utilizes a near flat point with radiused corners to create a smooth bottom with an aesthetically pleasing result.

The second tool (called the solid carbide rout and chamfer) is designed for plastic sheets. By combining both a straight flute optimized for cutting plastics with a cutting edge sized for specific sheet sizes and a 45 degree chamfer edge, these tools can rout out plastic parts and apply a variable depth edge chamfer in a single pass.To learn more about this tool and how it can improve your routing, or for inquiries about purchasing it click the following link: https://cncrouterstore.ca/onsrud-double-flute-solid-carbide-rout-and-chamfer/
The advances in router tooling have generally followed the rapid growth and usage of CNC routers. However, like what has been mentioned in previous blogs, merely choosing the correct tool without effective machining practices is an exercise in futility.
