Guideline Of Machining Polycarbonate Plastic (PC)

Polycarbonate plastic is one of the oldest polymer plastics, which was first discovered in 1898 by Alfred Einhorn at the University of Munich. And Bayer patented it and branded it as “Makrolon”. Today, it has become one of the most commonly used polymers across multiple industries.

Polycarbonate sheet is famous for its excellent strength, high light transmittance, and great processability, it is commonly used in car lighting systems, shatter-proof windows military warplane, electrical applications, etc. It is also used for greenhouse, architecture, tourism, etc. Today, we are talking about machining polycarbonate.

Machining is a great way to form plastic and make complicated parts. Some designs would be impossible without machining plastic.

CNC machining is a method where a cutting tool removes material from a plastic block or workpiece and shapes based on the design. However, because of the dynamic application and uses of the tools, the machining can be done in multiple ways.

Methods of Machining Polycarbonate Plastic


Turning creates rotational parts by removing unnecessary elements from the workpiece. Manufacturers need a lathe or turning machine and cutting tool for this process. The workpiece is attached to the tools and allowed to spin. Normally, polycarbonate rods will be machined by a lathe or turning machine.


This process is quite the opposite of the turning method. In this process, the cutting tools rotate around the workpiece and give it the desired shape by cutting unnecessary materials.


Drilling is another process to shape the plastic material. However, as it generates more heat, it is not advised for most plastic machining. But with skilled technicians and proper preparations, drilling can be done as well.


Polycarbonate Injection is the best method for large batch parts.


The grinding method is quite similar to the milling process; however, they have a fundamental difference. Intermittent cuts are used in the milling machining and while as grinding continuously shears plastic. As a result, the final parts have a better finish and are smoother.


For polycarbonate, you can cold bend it and heat bend it.

How to Choose the Right Machining Method for Your Project?

There are multiple options in choosing the right method. But, how do you select the best choice for yourself? The answer is not subjective. You need to consider different factors to choose before you go on with a method.


First of all, your design is the primary factor for choosing the right method. Because different methods require different kinds of machining. So, when the design is finalized, make sure you’re consulting with your manufacturer and choose the right one.

Just like the design, your material plays a vital role as well. Depending on the material type and grades, you should choose suitable machining. Because if you fail the right method for the right material, your production will not go successfully. You can choose a plexiglass sheet if you have a low requirement for strength.


Different methods provide different types of tolerance for the parts. Make sure you’re consulting with the manufacturer to understand this factor better.

Surface Finishing

Surface finishing is an essential factor to consider for choosing the method. Some methods offer better surface finishing than others.

If your parts need better and smoother finishing, grinding might be the better option. On the other hand, turning or drilling can’t offer the same level of smooth surface finishing.
