CNC Plastic Machining for Tight Tolerance Parts

For centuries, metals have been machined in order to produce different types of parts. However, as plastics have been replacing metals in several spheres of our life, the need for CNC plastic machining has grown tremendously in the recent past. CNC stands for computer numerical control, which entails the use of programs to command the machining process. Tight tolerances need to be followed while machining metals and the case with plastics is no different. Understandably, the types of machines and techniques used with plastics vary significantly as it is much softer than metals.

By making use of CNC machining to get the parts of desired dimension, you can benefit from the following advantages:

• The surface texture and optical clarity that is achieved with CNC machining is noticeably more superior. The overall finish is much better, thus giving your part or component a better look.

• If you have a medium or high capacity part requirement, then this is undoubtedly the best method. It provides you with consistent parts batch after batch. In a large production run, the cost per part is extremely low.

• Using this technique, the most complex contours, niches, angles, corrugations and threading can be achieved. Plastics are considered easy to work with, but only if your chosen firm has the right machines and technicians.

• Since everything takes place on a highly computerized platform, the entire process is tightly controlled. This reduces the chances of errors and you can expect a highly consistent quality of parts in every single batch. This process also offers you impeccable repeatability.

• Apart from just CNC plastic machining, other related tasks such as drilling, cutting and beveling can also be carried out.

• If your operations pertain to sectors such as electrical, optical, energy, aerospace, telecommunications, electronics etc, you can certainly consider using plastic machines parts instead of metal ones. Plastic is lighter, cheaper, low on maintenance and also durable.

• CNC plastic machining, as a process can be used for producing parts that are smaller than an inch and larger than 20″ in size. If you have any doubts about which process is suitable for you, you could consult your chosen service provider.

When it comes to this process, most service providers work with materials such as acrylics, Delrin, Teflon, and Lexan components. Each of these materials has a special use. The most suitable material for your application can be decided based on aspects such as part complexity, required tolerance, cost per part, turnaround time, etc. With the market being highly cost sensitive today, it is important to partner with a CNC plastic machining firm that can offer you the best expertise, services, techniques and solutions at the most economical rates.
