Manufacturing Services of CNC Turning Parts
Turning is a subtractive machining process that uses a cutting tool to remove material for creating cylindrical parts. The tool itself moves along the axis of the machined part while the part is rotating, creating a helical toolpath. we are going to look at the whole sequence here which actually starts from creating a CAD file.
①CAD design & G code
The first 2 steps can be seen as separate or going hand-in-hand. One way is to just use a CAD program to create the files and send them into production. The manufacturing engineer will then create the G code and the M code for the machining job.
Another way is to just use CAD-CAM software which lets the design engineer test the producibility of the part. The powerful simulation tools can visualise the whole process from raw material to the final product, even using the input regarding finishing requirements.
Lastly, there is also a manual way for creating the code. For example, you cannot automatically generate the code from a 2D drawing, leaving you with 2 options – either writing the code manually or producing a 3D model first.
Even the powerful CAM programs may not always get everything spot-on, So checking the coded instructions is recommended.
②Lathe setup
Next comes the machine setup. This is where the machine operator's role becomes evident. Steps for setting up a CNC turning centre:
Making sure the power is off. CNC machining can be dangerous, so extra care is necessary and checking the power switch is the basis for that.
Securing the part into the chuck. The chuck holds the part during the whole process. Improper loading can both pose dangers as well as result in a finished part with the wrong dimensions.
Loading the tool turret. Turning comprises of many steps, so be sure to choose the right tooling for a certain finish. The turret can hold many tools at once for a seamless operation from start to finish.
Calibration. Both the tool and part have to be set up in the right way. If anything is off, the result will not meet the demands.
Upload the program. The last step before pushing the start button is uploading the code to the CNC machine.
③Part production
Depending on the complexity of the part, one or more cycles may be necessary. Cycle time calculations determine the final time spent which is necessary for cost calculations. A turning cycle time comprises of:
Loading time. We already described it as part of the setup but a cycle may necessitate for another way of loading the part into the machinery.
Cutting time. The time it requires depends on the cut depth and feed rate.
Idle time. Idles times refer to anything that is not cutting, i.e. movement of tools to and from the piece, changing the settings of the lathe, etc.
Tool lifetime. Although each cycle does not wear out the tool completely, the cutting time will be taken into account vs the overall lifetime of a tool to include it in the final cost.
What CNC Turning Parts Can Be Produced
Symmetrical
You can have parts with asymmetrical features, but the overall part shape will need to be symmetrical. This has to do with the spinning of the work piece and the stationary position of the part.
Cylindrical or round
Again, due to the processes' nature, cylindrical or round parts are what is best suited for CNC turning.
Can be produced from bar or tube stock
The process is working from solid bars of raw material, or tubes. The inner and outer diameter are then shaped by the work piece. If the part is too big or too small, there may not be suitable material for working.

Medical Industry
Benefits of CNC machines in the medical field include the ability to create customized parts rapidly. When crafting individual designs, the CNC software allows engineers to see all aspects of the piece in three dimensions before machining it. This process ensures every component has the exact dimensions it needs to operate correctly.
Aerospace Industry
Devices in the aerospace industry encounter varied conditions, including high speeds, fast air currents and extreme air pressures. To avoid aircraft damage, engineers must construct each component with the most precise parameters, tools and parts. Even a small mistake could catch on an air current, producing drag or increasing wear on the parts.
Automotive and Transportation Industries
Many aviation industry components are also important in the transportation and automotive industries. Product research and testing are just as vital to these industries as they are to the air and space industry because they affect safety and the ability to travel. Transportation vehicles need robust components strong enough to haul heavy cargo far distances, and manufacturers rely on CNC-machined parts to produce dependable cars and trucks.
Oil and Gas Industry
The petrochemical industry uses large machines for refineries and drilling rigs. This line of work relies on well-machined, precise-fitting parts. Precise fits prevent issues such as valve leaks, piston failures and cylinder malfunctions. Petrochemical companies also rely on precise components to maintain efficient operations.
Military and Defense Industry
Similar to the oil and gas industry, the defense sector requires durable parts that withstand even the harshest environments. The government sets strict regulations for military activity. Just as medical supplies must have their production fulfill rules created by the FDA, military products need to adhere to government regulations.
Electronics Industry
CNC machining is an effective solution for manufacturing small components such as those used in electronics applications. Technological advancements depend on small, lightweight devices and components with laser-precise parameters under 10 micrometers, and CNC machining can meet these requirements.
Marine Industry
The marine industry also owes its success to the various CNC-machined components it uses. Many watercraft elements require unusual materials or shapes, and machining is the perfect method for meeting those needs with minimal effort.
Common Types of Materials for CNC Turning Parts
Stainless Steel
Because of its excellent corrosion resistance, strength, and machinability, stainless steel is a popular choice. It is used in a wide range of applications, including aerospace, medical, and automotive parts.
Aluminum
Aluminum is well-known for its lightweight properties and ease of machining. It is widely used for CNC turning parts in the aerospace and automotive industries.
Brass
Brass is prized for its corrosion resistance and machinability. It is frequently used for parts with precise and intricate details, such as connectors and musical instruments.
Steel Alloys
Steel alloys such as carbon steel and tool steel are used because of their strength and durability. They are widely used in industrial and mechanical settings.
Titanium
Titanium is a lightweight material with exceptional strength and corrosion resistance. It is a preferred choice for aerospace, medical, and military components.
Plastics
Plastics such as nylon, PEEK, and Delrin are chosen for their lightweight, non-corrosive, and self-lubricating properties. They are used in various CNC lathe parts, including bushings and gears.
