CNC Turning Process
Turned parts offer extraordinary precision in terms of depth and dimensions thanks to novel turning methods that give design opportunities and structural advantages that cannot be profitably replicated with any other production method. After securing a round, square, or hexagonal blank to the spindle's spring sleeves, CNC machines are turned on.
The blank then starts to rotate while the machine's numerous automated cutting, drilling, notching, and knurling tools turn it into precision turned pieces by trimming the superfluous material, smoothing it out, and drilling. The Swiss screw machine's primary drive shaft powers the machine bed's main work shaft and manages the two front camshafts.

The engine of the machine, which is housed in the base of the machine, produces turned pieces, and its power varies based on the size, speed, material being processed, and the main power source for all operations. By holding and spinning a blank, also known as a workpiece, on a single spindle while the drill bit completes the cutting operation, a CNC lathe is a computer-controlled machine tool capable of creating precision turned parts.
In more recent developments, CNC lathes are rapidly replacing the earlier types of lathes because they are generally thought to be simpler to set up and run and because they require less in-depth lathe knowledge. Typically, the operator and setter are the same individual in factories that produce precision-turned parts.

Applications of Precision Turned Parts
- Materials utilized for precision turned parts include titanium, acrylic, brass, polycarbonate, nylon, copper, polyvinyl chloride (PVC), stainless steel, and aluminum, all of which can be created from even the most rigid of materials.
- Precision turned parts, such as shock absorber bolts, axle nuts, driveshafts, interface fittings, pneumatic tool accessories, shafts, machinery parts, flanges, nozzles, and housings, have outstanding surface finishes.
- Turned components can be used in a variety of industries, including electronics, automotive, appliance, HVAC, marine, medical, telecommunications, petroleum, and optical thanks to their extensive range of applications.
- Tight tolerances are used to manufacture complicated components that make up precision medical products. To ensure adherence to medical standards, they are made of sanitary-grade materials like titanium and stainless steel. Turned parts offer extraordinary precision, depth, and dimension thanks to novel turning methods that enable design capabilities and structural advantages that cannot be cost-effectively replicated with any other manufacturing technique.
- Industries employ turned components to secure goods in place. Precision components are advantageous to the aerospace, oil, and defense industries. Since they provide high levels of performance for their desired application, precision components are also used in the medical, electronics, and hydraulics industries.

Advantages of Precision Turned Parts
- CNC machining provides better performance. Components that have been CNC turned can run continuously before any maintenance is necessary. With fewer needed adjustments, there may be a significant amount of labor savings during the production process.
- CNC turned components operate in accordance with pre-programmed instructions that specify the precise paths and directions to be taken. Excess material can be drastically reduced, producing cheaper costs and creating enticing sale prices.
- Any production process might be dangerous if the employees are straying. Let's use the examples of laser cutting, punching, welding, or hearing raw materials. Every movement of CNC machines can be incredibly exact and versatile with pre-programmed instructions thereby highly reducing the likelihood of workplace accidents.
- Quality is one argument for picking a sector with a CNC machine shop to meet production demands. The use of machines makes sure that all fundamental procedures are optimized, boosting the output's uniformity and speed. It takes less time if the technician doesn't have to drill manually. Except for repairs, CNC equipment does not need to be turned off, assuring continuous output. Machines don't have to deal with breaks or fatigue, making production a more efficient process. Procedures that ordinarily require multiple pieces of equipment and numerous hands only require one.
Choosing the Right Precision Turned Part Manufacturer
To make sure you have the most beneficial outcome when purchasing precision-turned parts from a precision turned parts manufacturer, it is important to compare at least 5 companies using our list of precision-turned parts manufacturers.
