To better understand precision mechanical machining. We learn about the definition and application of precision machining:
Before going to the definition of precision machining, let’s first understand what is the definition of mechanical machining?

What is machining?

    Machining is the process of removing material from sheet billet, casting billet, block billet.. to create products with the required shape and size.
    When the mechanical processing industry has not developed to achieve this, we have to use rudimentary tools such as knives, hammers, chisels to create products.
    Currently, machine tools such as turning, milling, electric firing, wire cutting .. are controlled by CNC computer (computer numerical control). Use tools such as milling cutters, lathes, grinding wheels, electrodes to create products.

What is Precision CNC Machining?

   Precision CNC machining is the same exact concept as CNC machining in general, only subject to higher standards. While CNC machining services in general have provided fairly precise outputs, precision CNC machining holds much tighter tolerance standards, meaning more complex shapes can be machined. with less error. 
   This is useful for projects that require high precision such as medical devices, aerospace technology and more.

Applications of Precision CNC Machining

   The precision mechanical processing industry develops very quickly. To illustrate this we can take the following example: The first flight of human history was recorded on December 17, 1903. From that point on, the aircraft was continuously improved. develop.
   From the beginning, the aircraft details were very simple due to the low level of processing and manufacturing. Crafting products depends on the skill of the mechanic.
   In just over a century, with the rapid development of the manufacturing industry, aircraft design engineers have put together many parts to create a complex part. This intricate detail can only be made with state-of-the-art machine tools.
   This eliminates a lot of fasteners and fasteners that reduce the weight of the aircraft. Increased fuel efficiency and very high stability.

The following are some of the most prominent advantages of precision mechanical machining over manual part fabrication.

High precision CNC machining

   Combines the precise rotation of a servo motor, the precision of a ball screw and guide sliders. We can make micrometer-precise parts. This is especially important for many industries such as medical, semiconductor, automotive, aircraft, etc.

Precision CNC machining with stable quality

   Unlike manual processing, which depends entirely on the skills and emotions of the workers. Precision machining by machine tools is controlled by CNC computers, so the machining movement from part to part repeats almost absolutely.
   This results in products made by precision machining with highly repeatable shapes and sizes. Produce stable quality.
   Consistent quality products are not only beneficial in enhancing the brand’s image in terms of both design and safety, but also in reducing the number of poor quality outputs.

Precision CNC machining has a low error rate

   Labor is important and necessary for many manufacturing processes, and mistakes are bound to happen, especially with the rapidly changing technology and global manufacturing landscape. Precision machining or working with a CNC machine to cut materials can produce accurate and consistent results, minimizing or eliminating manufacturing errors.

Precision CNC machining is less material waste

   The advantage of precision machining is that the quality is stable, so precision machining has the ability to reduce error rates and produce products of uniform quality, helping manufacturers avoid having to throw away many substandard products. quantity and avoid processing to compensate for the amount of waste generated.

Precision CNC machining increases production efficiency

   After the benefits listed above, it is clear that precision machining allows manufacturers to work at much faster speeds and produce more products than before, thereby increasing efficiency.
   It also allows manufacturers to direct their workforce to other aspects of production that require more human labor than machines.

Precision CNC machining makes the price is cheaper

   With a lower risk of errors and day-to-day stability, precision machining can significantly reduce production costs. It allows manufacturers to have a clear financial plan for the production process and not have to allocate a budget for contingency. In addition, the precision machining process also cuts down on labor costs.

Precision CNC machining makes production safer

   Occupational accidents are always present in the production process. The characteristic of precision machining is that it uses less labor, so the number of work accidents will be reduced.
   At the same time, because the cutting process is controlled by a computer, workers do not need to be in close contact with the machining position. This significantly reduces the rate of occupational accidents when an incident occurs.
   According to the U.S. Labor Statistics Bureau of Fatal Occupational Injury Census 2017, there were a total of 303 fatal injuries in the manufacturing industry that year.
   Accidents with machines are some of the most common and most devastating in the industry, but fortunately, precision machining automatically eliminates or minimizes the chances of it happening.
