Turning and Milling Finishing Options
At Prolean, we understand that achieving the perfect finish on a machined part can make all the difference. Every project presents unique demands; perhaps a glossy sheen, a tactile texture, or even a resilient protective layer. With a commitment to craftsmanship, our team ensures that the resulting piece isn’t just functional, but also aesthetically in line with your aspirations. Delve further to discover the array of specialized finishing options we proudly present, curated to elevate the resilience, allure, and performance of each machined component.
The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).
A thin layer of Nickel is created on the surface from a nickel-containing solution without electrolysis. Electro-less nickel plating provides a shiny appearance, excellent hardness, abrasive, wear, and corrosion-resistance to the substrate material.
Make the parts super resistive to corrosion. It enhances mechanical strength, hardness, wear resistance, lubricity, and ductility. Nickel plating is applicable in different materials, including Steel, aluminum, copper, and brass.
A shiny appearance with goldish color provides excellent corrosion resistance. It is applied on the surface of aluminum, magnesium, and their alloys. A layer of chromate also enhances the conductivity of parts
The higher-precision machines produce delicate machining surfaces by utilizing sharper tools and regulating feed rate and cutting speed. Surface roughness up to Ra 0.8 μm can be maintained with smooth machining.

What is CNC Turning-Milling?
While turning machining only rotates the workpiece and milling machining rotates the cutting tools, turning-milling machining combines both approaches in which both the workpiece and the tools can spin following the demands of the CAD file and input instructions.
A mill-turn center machine is used for the Turning-milling machining, basically, a hybrid system that performs both Turning and milling operations simultaneously without switching the device. Because complex geometries require both processes, this approach eliminates the need for frequent machine switching and streamlines manufacturing compared to the normal CNC machining process.
Both milling and turning tools are included in CNC mill-turning machines, and they are set up so that they can be used simultaneously and quickly under input instructions from a computer.
Use of CNC turn-mill machine
The various components for the automotive, aerospace, defense, medical, and mechanical industry requires geometries that involve both turning and milling operation. The CNC Turn-mill machine is ideal for such cases. However, it might not be cost-effective to use it to manufacture items where one process is sufficient, and the operator might have to cope with a more complicated setup.We recommend the CNC turn-mill is ideal when the milling required on the part is less than 25 %.
Working Principle of CNC Turning Milling
The working bar is fastened to the chuck on the spindle and rotates rapidly when computer commands direct the turning operations. When milling operations are required, it becomes stationary, and the rotating tools begin to move to feed the material.
The CNC turn-mill machine can perform turning, milling, boring, facing, drilling, and many other operations. The rotational direction of the machine that commonly uses the milling head is referred to as the “B-axis” in turn-mill machines. The workpiece is fastened to the milling head, allowing various tool-to-workpiece angles.
There are four standard Axis of movement. X-axis: Movement perpendicular to the Axis of the workpiece, Y-Axis: movement using a live tool or separate milling head perpendicular to the Axis of the workpiece, Z- axis: Movement along the stock axis required when holes need to be drilled in the center of the workpiece, B- Axis: movement around the Axis of the workpiece.
The CAD file is first loaded onto the device, and the program is customized following the drawing. Before beginning the process, the turning-milling operation instructions are provided. Even after that, manual supervision is required to ensure quality. However, it doesn’t need different programming or education for each process—just one program will do.

What kind of CNC turn-mill equipment do ProLean's use?
We have a Feeler HT-30SZ, 5-axis mill-turn machine that can mill and turn bar stocks, castings, forgings, billets, and other complicated components while maintaining high accuracy. While Copper, steel, Brass, Titanium, plastic, and many more materials can be used in CNC turning-milling.
What is the smallest thickness I may incorporate into my design to prevent warpage during the turning-milling process?
We offer a minimum thickness of 0.5mm and 1mm for metal and plastic, respectively. However, the value is greatly influenced by the size of the created parts. For instance, you might need to drop the minimum thickness limit for large parts and raise it for much smaller parts to minimize warpage.
What are the Advantages of Using the Turning-milling process?
Comparing a turning-milling process to separate milling and turning operations, the combination has many benefits. Turning-milling generates accurate parts using the same machining setup, which reduces production time instead of performing independently, necessitating separate setup, instructions, and tool arrangements. Compared to an individual approach, the single configuration reduces adjustment and fixation time and maintains tight tolerance because handling different machines requires labor and raises the possibility of dimension error.
What parts can be made with the Turning-milling process?
We offer Precision measurement equipment, craft and automotive parts, parallelepiped-shaped parts with threaded holes, and other complex shapes using a CNC turning-milling technique.
What is the key difference between CNC milling and Turning?
The CNC milling method utilizes rotatory tools and a stationary workpiece, whereas the turning process rotates the cylindrical workpiece, and the tool remains stationary to achieve the desired shape.
