What Is Precision Machining
What Is Precision Machining?
Precision mechanical processing has many outstanding advantages when using modern machines. It is to create mechanical products that meet the requirements of high precision and increase productivity many times.

Currently, in enterprises and mechanical workshops, the type of precision mechanical processing is very widely common. Machining is about 40% to 60% of the whole process. Precision mechanical processing has the highlight of using modern machines and technologies. Moreover, it creates high-precision products.

What is Precision Machining?

Precision mechanical processing or CNC machining is a machining operation. Moreover, it uses a system of modern, high-precision equipment and machines such as:

  • milling machines
  • Lathes, etc., along with high-speed robots.
  • high capacity and precise technique to work

What Is Precision Machining? Precision mechanics apply to materials such as glass, graphite, steel, stainless steel, plastic, etc.

The difference between precision mechanical processing and other types of mechanical processing is the use of a variety of modern machines and equipment. Therefore, the products are created with almost absolute accuracy.

What are the characteristics of precision mechanical processing that are widely and commonly common today?

Advantages of precision machining:

We can also easily recognize the advantages and benefits of precision mechanical processing:

Not too demanding on the hardness of the processing material. Furthermore, almost all materials are easy to machine especially materials with high hardness.

The smoothness of the product surface and the accuracy of the proportions and dimensions are much higher than those of mechanical products processed by other methods.

Importance of CNC Precision Machining

CNC turning and CNC milling can make complex and high-precision products, especially specializing in the processing of torsion axes with 4-5 axis CNC milling machines, 3-axis CNC lathes.

The outstanding advantage of precision mechanical machining is that it is capable of machining almost any material with only negligible mechanical force, etc.

What Is Precision Machining? Besides the advantages mentioned above, precision mechanical processing also faces many difficulties because of the specificity of the industry and in addition, CNC machining is one of the new technologies, so the operator also got into a lot of trouble.

Precision mechanical processing products

Types of mechanical processing:

Currently, there are two types of mechanical processing:  CNC precision machining and traditional mechanical processing.

CNC precision machining:

Precision mechanical processing is an important key factor in modern industry in general and supporting industries in particular. In the process of processing and manufacturing according to customer requirements, precision mechanical processing proceeds the most, especially precision machining, planning, and turning, which accounts for a large proportion.

What Is Precision Machining? A big difference between precision mechanical machining and traditional mechanical processing is the application of modern machines and advanced technologies to create products with near-excellent precision opposite to.

Some forms of CNC precision mechanical processing:


CNC milling machining: is a form of machining based on CNC milling machines with the movement of the main shaft. It is to create movement to the workpiece to create cutting movements by using milling cutters, drill bits ... to machining. Machining surfaces work on the workpiece corresponding to grooving, face milling or hole boring or other machining.

CNC turning processing:

What Is Precision Machining? CNC turning products will be processed on CNC lathes to process rotating cylindrical surfaces with corresponding cutting tools. The products are usually processed for internal and external threads, internal turning, and external turning, face cutting, step cutting, etc.

Gas processing, plasma machining, and CNC laser: This is a form of non-contact machining that does not use cutters, milling cutters, drills, etc. to process, but rather uses heat to cut workpieces through cutting tools.

Traditional mechanical processing:

Traditional machining methods need the work piece to always have a lower hardness than the tool to remove the material on the workpiece.

This traditional machining method is similar to advanced machining methods. CNC machining is to use the movement of the cutting tool and the workpiece to create the shape of the surface to be machined. Traditional machining methods are frequently common such as: Milling, turning, planing, drilling, reaming, grinding, knife, slotting, tooth milling.

Advantages of CNC precision machining

Besides the question "What is precision machining?" What are the advantages of CNC precision machining? It is also a question that many customers want to find out. To help you answer the above question, here are the most prominent advantages of CNC machining methods:

First, the CNC machine works by coding commands received from the control unit. After the technician enters the digital data directly on the computer, the control unit will command the device to perform movements such as planning, drilling, grinding, knife, milling, turning.

Due to automatic execution by the machine Hooks should be precisely machined and is easy to do with most materials, including high hardness materials. Similarly, these are steel, stainless steel, glass, graphite, plastic, composite materials...

Second, precision mechanical processing ensures a high level of product accuracy, almost absolute:

  • Surface smoothness: The surface is precisely machined, highly aesthetically pleasing, with few defects or damage. The curves are smooth; the small details come easily without affecting the overall texture of the material.
  • High drawing scale accuracy(error as small as 0.001 mm): CNC machines make the most of cutting modes, cutting principles and mounting options, ensuring precise cutting and quality stability product quantity.
  • The machine automatically adjusts tool errors, automatically checks the detail size. Thereby automatically correcting the relative position deviation between the tool and the part, ensuring the smallest error.

Third, precision machining ensures mechanical processing productivity

What Is Precision Machining? The steps are programmed automatically, so the machine can operate continuously, without interruption. The higher the machine's performance, the higher the work productivity will be.

As a result, it is possible to completely replace the traditional production stages. Furthermore, enterprises guarantee the progress of work as well as costs and product prices.

Fourth, CNC machining can perform high-complexity mechanical processing, processing a series of small parts quickly. This is thanks to pre-designed programs on the computer. The program can be easily changed according to the requirements of each product.


The machine integrates many features such as pause, speed increase and decrease, depth/shallow adjustment, so it is easy to process complex, high-demand products.

Fifth, you can save the processing program and software for future reuse. The machine uses drawings designed on software such as JDpaint, Artcam, V-CARE, and Rhino... Enterprises can easily save drawings and use them.
