Precision machining is a processing technology that has gradually become popular in recent years. In daily life, many tools/items we use and rely on have high precision requirements for their parts and components, and precision machining emerges to meet these high precision requirements.

Nowadays, the market competition is fierce, and the standard of excellent products is constantly rising, which also leads to higher requirements for the accuracy of most parts. As a manufacturer, we have also contacted many customers who have high requirements on the accuracy of parts in recent years. However, due to some characteristics of precision machining, some parts are actually not suitable for precision machining. So which parts are suitable for precision machining? How do we judge whether the parts are suitable for precision machining?

If you are interested in the answers to these questions, let us answer them for you.

What is precision machining?

Before answering those two questions, we need to understand what precision machining is.
It is a more rigorous processing technology than ordinary processing, and it can also be said to be a kind of subtractive processing. In precision machining, material is often removed from the raw material of a part to create a finished product. The production process and tolerances of the parts are maintained within a fixed and small range.
Precision machining can be used to make a wide variety of products, items, and parts, but is currently mostly used to make tools and parts. Its high precision, high stability, repeatability and excellent durability are especially important for manufacturing tools and parts.
Many tools are very complex machines that can be found by constantly disassembling them, and they are all made up of individual parts. These parts, however, often require tight control over standard dimensions and tolerance variations between parts to ensure they are produced, fit together accurately and work properly. This also means that there is not much room for error in the production of these parts. So usually, these small parts are made using precision machining.
In addition, precision machining ensures that these small parts can be consistently and repeatedly produced with this precision. Therefore, another common application direction of precision machining is the production/repair of tools or parts. A tool or part that has been used for a period of time may need to be recalibrated, slotted or welded to restore it to its original form when not in use. This can also be done by precision machining.
Precision machining is often used in conjunction with CAD and CAM programs. Engineers use CAD or CAM programs to create product drawings, which are then entered into precision-machined tools, where machines replace humans and process materials with greater precision.
Today, precision machining is an indispensable machining process. And, it is still moving forward over time, and there are many related technologies that are constantly improving, which will further help precision machining to break the current limit and achieve higher performance.

What parts are precision machining usually used for?

Many industries require high-precision parts, such as medical, aerospace, electronic products, automobiles, etc. Among them, medical and electronic products have the most urgent demand for high-precision parts.
With the development of high-precision technology, medical equipment and electronic products are constantly being optimized, updated and iterated, resulting in smaller, more complex, and more precise parts needed in these industries.

Are all mechanical parts suitable for precision machining?

Unfortunately, the answer is not yes.
Due to the scope of application, some mechanical parts will use some raw materials with higher hardness, and the hardness of the tools used in precision machining is limited. Forcibly processing those materials with higher hardness is likely to cause damage to the lathe equipment, and at the same time it cannot be produced. Compliant parts unless they are laser cut equipment parts.

Which mechanical parts are more suitable for precision machining?

Industries that require high-precision parts are well suited for precision machining, such as:
Auto parts: power system parts (with the highest precision requirements), shaft parts, relays and other functional parts.
Electronic products: functional parts such as connecting devices, structural parts, elastic parts, etc.
Medical equipment: functional parts such as adapters, micro stamping parts, shaft parts, etc.
Others: instrumentation parts, information technology parts, acoustic and lens parts and other precision parts.

At the end of the article, we need to remind you: in theory, every CNC machining shop should have the ability to manufacture high-precision parts. However, when you do want to make some really complex and precise parts, we recommend that you’re better off using some more sophisticated machines for quality production.

Sincerely hope that the above content can be helpful to you.
