There are multiple types of CNC machines, each with different functions. CNC lathe machines play a significant role in the transmission parts industry, such as shafts, gears, etc. Below, you will learn about all of those parts and their impact on the industry. What are CNC Turning Parts? They are turned parts or cylindrical parts made by CNC lathe machines. Some people call them CNC-turned or turning parts. Simply, they are cylindrical-shaped parts that function in rotational activities inside machines. For instance, you will find transmission shafts, dowels, taper, roll pins, bushings, etc. They are some of the components of a machine. CNC machining is the fundamental requirement for producing them.  Machines' circular or rotational movement, such as those in automobiles and aircraft, makes them unique. This is why uniformity is a key factor in production. If we compare the turning method with CNC milling, we will see that they are two different processes. Turning Vs. Milling  In the turning process, the workpiece rotates and moves back and forth, however, while thecutting tool performs in a fixed position. The cutting tool makes the cuts, curves, and threads on the workpiece in a cylindrical shape. In the milling process, the cutting tool moves in different directions while the workpiece remains stationary. This process is different, but the results are similar. The milling process helps when detailing and complexity are required.   The CNC Turning Process: How CNC Turning Parts are Made This machine deals with rotational movement, where a simple metal billet is placed in the clamps. A CNC machine operator provides instruction in numeric codes to convert the results from digital to physical form. The rotation process starts, and then the cutting tool gives that metal billet a meaningful form. When the billet or workpiece rotates and moves back and forth, the cutting tool turns it into a shaft, taper, bushing, etc.   Every cut takes place precisely because this makes CNC machines the best among other methods.  Comparison with Lathe Machines There is some confusion among the non-professionals who assume that CNC lathe and lathe are the same. No, they are not the same machines. In fact, CNC lathes are much more advanced, precise, and faster than traditional lathes. However, you might be thinking about milling machines that perform similar operations. Again, the milling CNC machines are different. Their production method and results are various from CNC lathes. Milling machine purely focuses on high detailing, complexity, and sharp angles. CNC machines have a high edge with the help of programming, speed, and precision. Key Materials for CNC Turning Parts Usually, stainless steel and aluminum play significant roles in the CNC-turned-parts industry. However, you will find popular material choices like brass, carbon steel, titanium, and bronze. These different materials have different strengths and weaknesses for various applications. Factors that you will have to look at are many. Some of them are hardness, machinability, corrosion, and crack resistance. Some metals are extremely hard, and they have low machinability. However, some are soft, and they can crack on high detailing. So, you have to choose  Applications of CNC Turning Parts in Different Industries You can expect their applications since these turned or turning parts are involved in rotational movement. They are common in the automotive, aerospace, and general machinery industries. Their prime installations are in transmission parts, where gears, shafts, and bearings are common. An engine requires coordinating with these components to run an entire machine.  CNC-turned parts are lightweight and precise, which is why they are suitable for aircraft. They perfectly align with the other components to coordinate. The entire aerospace industry uses these parts that offer precision, compatibility, and lightweight impacts. Their high tolerance and precision also make them suitable for the medical industry.  Medical and Electronics Industries: Cover applications in these fields, focusing on the need for accuracy and small tolerances.
