CNC precision machining company

CNC precision machining usually means that the part corresponds to the parameters specified in the drawing. This aspect concerns the shape, size, correctness of the parts’ relative position, and the surface condition.

Any production must always meet certain parameters. One of them is the precision of processing parts. Many factors depend on this aspect. Service life of products, the possibility of replacement, and the pace and efficiency of final assembly using the machine method.
Compliance with standards is necessary to ensure uninterrupted production. Indeed, at the production rate of finished precision, parts pass through the machine not even in minutes but in seconds.

The Role Of Precision Machining In Key Industries
Precision machining plays a significant role in several important industries. Hence, it ensures the improved productivity of high-quality parts meeting desired needs: Some of the major industries which heavily rely on CNC precision machining are:

Aerospace:
Several precision mechanical parts can be manufactured using CNC precision machining. The major parts include turbofan blades, landing gear parts, and structural elements. Simultaneously, precision machining contributes to aircraft and spacecraft safety, performance, and reliability.

Medical:
Medical equipment, implants, and diagnostic equipment require precision machining to produce complex parts. Furthermore, precision mechanical parts play a key role in the medical industry by providing exact specifications.

Automotive:
CNC precision machining is highly effective in manufacturing engine precision parts, transmission components, and complicated systems. These systems include fuel injection and brakes. Precision machining highly improves vehicles’ fuel efficiency, performance, and safety.

New Energy：
As the world continues to explore oil and gas and use renewable energy technologies, precision- parts are becoming increasingly important. CNC precision machining is highly productive in multiple key defense equipment,
And complex systems， such as radars and communication devices.

Introduction To CNC Precision Machining
Achieving 100% compliance is not possible. There will always be deviations to some extent. Therefore, tolerance becomes an important parameter. In one batch of precision parts, up to hundredths of a millimeter is possible, and in another – up to tenths of a micron.
Accordingly, it is necessary to fit within the specified range. And this becomes possible with a combination of high-quality equipment and qualified CNC machinists performing the work. After all, some machines simply initially have an error that will not allow you to adjust the hardware to the tolerance parameters.

Enhanced Accuracy And Consistency
Let’s understand the basic terms that characterize the concept. The first of these is the nominal size. It is the length, width, and height parameter specified in the initial documentation.

The precision of processing the surfaces of a part demonstrates its importance precisely in the mating elements – those that come into contact with each other’s surfaces over a certain area. In addition to the fact that they must be interchangeable, it is worth understanding that mating requires an ideally selected surface.

Otherwise, there will be increased friction and unaccounted energy consumption because the hardware will slow down the speed. Also, the service life will be greatly affected, especially during intense work. From this perspective, the service life can be reduced tens of times.

Versatility in Design and Production
With conventional machining methods, achieving complex shapes and geometries can be challenging. In industries such as aerospace, where aerodynamic designs are crucial, CNC precision machining can manufacture following complex geometries.

Benefits of Custom Precision CNC Machining
Computer numerical control (CNC) allows manufacturing engineers to transform machining from a routine manufacturing process into a precision art. Manufacturers are eager to adopt CNC machining due to its range of accuracy, time, labor, and materials advantages.

The following are some of the benefits that manufacturing organizations can gain by using precision CNC machining to produce parts:
Fully Automated:
As compared to manual machining, modern CNC machines are fully automated. Since CNC machines are automated, they do not require regular monitoring. Ultimately, it reduces human input and improves performance. By reducing the number of workers needed, manufacturers can utilize their existing workforce more effectively.

Faster Production:
In most cases, CNC machines can perform operations without any mid-breaks, allowing manufacturers to increase productivity. Ultimately, they can speed up their production to meet deadlines. Quick production rate means more orders.

Consistent Product Quality:
Human machinists can make mistakes when creating large quantities of components. It is possible to replicate machine parts exactly every time CNC machines are used. The importance of this can’t be overstated in industry since a small defect could lead to parts that are no longer working, which can require unnecessary time, effort, and expenditure.

Ideal For Producing Complex Parts:
An example of multi-axis machining can be found in manufacturing parts from large metal sheets. For this process, manufacturers use a machine tool to maneuver along multiple axes to produce parts from these large sheets.
Many CNC lathe manufacturers provide machining capability in three, four, and five axes. There is a lot of potential to create complex parts with holes that are bent or curved through the use of multi-axis machining.

Learn inspection

This technological process includes:

1: After the workpiece is put on the machine, the work should be re-checked according to the drawing and process. Only when the inspection is within the tolerance range can be processed according to the requirements of the program sheet, so that the drawings, processes, and the program sheet are all corresponding.

2: In terms of size, the touch of the workpiece, and the size of the insertion position meet the requirements of the 3D drawing file. For the position of EDM, CNC needs to leave the EDM margin, and the more important assembly positions should be measured by 3D inspection.

3: For some extremely irregular CNC surfaces or positions with high size requirements, some positions that cannot be measured by common measuring tools, three-dimensional measurement is required if necessary.

4: the workpiece must not have rust, bumps, chipping, and burrs. At the same time, there should not be a large amount of residual cutting fluid, cutting oil, and iron filings in the holes on the surface of the workpiece.

5: According to the 3D drawing file, check whether the workpiece has been completely processed without omission, the benchmark is correct. All the positions requiring sharp corners (especially the sealing position) cannot be chamfered or R.And check the size according to the drawing and then check the self-check. stated on the slip.

6: The CNC machined electrode requires no burrs on the surface, the serial number and electrode number are complete, clear, and correct, and there must be no writing other than the electrode number and electrode number.
