Milling, as opposed to sawing, provides a superior edge finish, which is one of the many advantages of milling. Milling also allows for more precise creation of complex shapes than sawing does. Milling is the most effective technique to use when fabricating house letters, numbers, and nameplates. Keep reading to learn the most effective strategy for milling polycarbonate, and good luck!

1. Make use of a wood milling machine or a router

Polycarbonate can be milled by anyone, including professionals and do-it-yourselfers, but the right milling tool is absolutely necessary. When CNC machined Polycarbonate comes to CNC milling plastic, professionals typically use multi-axis CNC milling machines and flatbed milling tables. However, if you're a do-it-yourselfer at home, you can get the job done with a wood milling machine or router. In the polycarbonate sheet you are working with, you can use a router to mill grooves and profile edges, or you can use templates to mill out shapes. Sawing with accuracy can also be accomplished with a router.

 

 



2. Ensure that you have access to a sharp cutter

Before you begin milling polycarbonate, you should make sure that the cutter on your milling machine is sharp and that it has adequate chip removal capabilities. If your milling machine has a connection for a vacuum cleaner, it is strongly suggested that you make use of that connection.

3. Make sure you choose the appropriate cutter diameter cutter

Utilize carbide (HSS) cutters with a single edge, and make sure to choose the appropriate cutter diameter. Milling a panel with a thickness of up to 5 millimeters requires a cutter with a diameter of 4 millimeters. If the thickness of the panel ranges from 5 to 10 millimeters, you should select a cutter with a maximum diameter of 6 millimeters. Routing panels with a thickness of 10 millimeters or more should be done with a cutter measuring 8 to 10 millimeters.

4. Hold the CNC machined Polycarbonate in place while you mill it.

During the milling process, the panel and the milling cutter should both be supported. During the machining process, vibrations can be eliminated by supporting the panel on a stable surface. Choose a surface that the cutter can run into, such as a wooden board if you want to go this route. It is important to have adequate support for the top of the panel so that it can be pressed against the surface. Utilize slats and clamps or clamps that support the panel along the milling line in order to accomplish this task.

5. Grind in several distinct stages

Milling thicker sheets typically requires more than one pass through the machine. If you don't do this step, you won't have a clean edge finish when you're done. One pass through the milling machine can produce thin panels with a thickness of up to 5 millimeters. Make sure that you mill in the opposite direction of the rotation of the cutter, as this will result in a smoother edge produced by the milling. We recommend milling panels with a thickness of up to 10 millimeters in two steps, and milling panels with a thickness greater than 10 millimeters in four steps. If you want a better edge finish on the fourth pass, run your cutter at a slightly slower speed.
