It is a well-known fact that CNC routers require bits. They play an important role in determining the type of processing that can be carried out. Your finished designs’ resolution is also determined by bits. They feature cutting edges that perform activities like pulling up or pulling down. While most of them have square-shaped corners. As far as accuracy or speed is concerned, they never falter.
Compression Bit: What Does It Mean?
A compression bit can be defined as something that is an amalgamation of downcut and upcut spirals. A compression spiral, traditionally, comes with an upcut single. At the cutter’s tip, you will see either a double or a triple flute.
If you want to get the best out of it, you have to combine the two geometries of bit breakers properly. While the material’s bottom part is pulled upwards, the topmost portion is pushed towards the bottom. Because of this, there remains no risk of the laminated surfaces getting damaged.
Compared to a regular router bit, a compression router bit tends to be more expensive. However, when it comes to processing or working on laminated wood materials, it emerges as a very important tool. When you use it, you can be sure about the work getting done far more efficiently.
What Makes Them Useful?
Compression bits are largely used for the purpose of carving plywood or melamine which happen to be double-side laminates. You also have the option of using them on other materials like natural wood.
On many of the materials, other types of equipment do not work that well. Using conventional spiral tools on natural wood, for instance, is not a good idea as edge finishing wouldn’t happen properly. In such situations, using a compression router bit proves to be your best bet.
Using a Compression Router Bit
While a compression router bit proves to be the best tool for working around double-side laminates, you will not be able to benefit from it if you don’t use it correctly. The cutting edge of a compression router bit is on the side. This is one of the most important things you need to remember while using the tool.
The process of using the tool during downward spirals is different from the way it should be used when you opt for upward spirals. It would be advisable to take basic training from somebody who knows how to use it well.
How do I use this tool correctly?
Although compression bits are the preferred tool for cutting double-sided laminates, it's crucial that you utilize them properly.
As the waste material is hoisted out of the cut line and into the extraction system, a direct plunge into the material will be acceptable for your ordinary upwards tool because the cutting edge of most tools is on the side of the tool.
However, it is preferable to ramp into the material for downward spirals and/or compression tools. This method prevents the swarf from compressing at the tool's base and producing intense heat. The workpiece and the tool's cutting edge will be harmed by this heat.
