CNC turned parts are manufactured by subtracting materials from a workpiece until a specific shape is arrived at. The process is mainly computer-controlled and automated. It is used for producing high-quality CNC-turned parts. They can be used for a wide range of applications in various industries, like aerospace, defense, electronics, and automotive. This write-up focuses on the qualities of CNC-turned parts.
Characteristics of CNC turned parts
The following are some of the primary characteristics of parts made from CNC turning:
1. High precision
One of the main qualities of CNC-turned parts is high precision. This is because CNC turning is a highly precise machining technique. The first step of the manufacturing process is creating a blueprint.
This is done using CAD software. Once the model (blueprint) is complete, the next phase of the process is feeding instructions to the CNC turning machines in the form of G-code.
From there, the device takes charge of the movement of the workpiece on the chuck. A computer wholly controls this process. This helps achieve high precision. It is also worth mentioning that the high accuracy of the products is achieved because of three or more axes.
The role of the axes is to guide the movement of the workpiece. Swiss turning machines are specifically beneficial in this area because they use five or more axes for the process.
2. Various shapes
CNC turned parts come in a wide range of shapes. However, the most common shapes are round. For instance, the process can be applied for manufacturing products like probes, pins, fasteners like screws, nozzles, and connectors, to name a few.
3. Various materials
CNC-turned parts also come in a wide range of materials. this is because the manufacturing process allows for the application of a wide range of materials. The most common types of materials applied in CNC machining are various metal alloys, steel, brass, stainless steel, copper, and multiple types of plastic, to name a few.
Advantages of using CNC turning for making custom parts
One of the primary applications of CNC turning is manufacturing custom parts. Below are the benefits of using this machining technique;
1. High turning efficiency
CNC turning machines offer higher turning efficiency compared to other manufacturing techniques, like grinding. This element means that the method can achieve larger cutting depths. The high turning efficiency also means that you can achieve a wide array of surface machining with one-time clamping.
2. Low costs
CNS turning also does not consume a lot of money. This is because the process does not require special equipment. This is especially the case with small-batch production. Regardless of the low costs, the process offers impeccable rigidity, position accuracy, and high levels of repeatability.
Other advantages include:
- The great overall quality of the turned parts
- It is ideal for small batches
- A wide range of tooling choices
Note that there are two primary forms of CNC turning; conventional CNC turning and Swiss CNC turning. Each has its specific advantages and downsides. Of the two, swiss CNC turning offers more benefits than the latter.
