What is precision parts processing?
Precision part processing refers to the manufacturing process of components with extremely high
dimensional, shape and positional accuracy by using high-precision equipment such as five-axis machining
centers and centering machines, along with professional techniques, such as cutting, milling, turning,
grinding, electrical discharge machining (EDM), laser processing, etc., on metal or plastic materials.
It is widely applied in industries such as aerospace, automobiles, medical devices, optical equipment,
robotics, communication electronics, etc., and requires high standards for processing equipment, tooling
techniques, detection instruments, and the experience of operators.
The core of precision processing lies in the control of dimensions at the micrometer or nanometer level
and strict quality stability. It often needs to combine CNC numerical control processing, five-axis
linkage processing, and three-coordinate detection and other technical means. Through precision part
processing, complex structures, strict tolerance requirements, and high surface finish of customized
parts can be manufactured, providing reliable support for enterprises’ research and development,
small-batch production of products, and high-end equipment manufacturing.
Advantages of precision-machined parts
High precision and accuracy
This process can produce parts with the highest dimensional accuracy, and therefore is often the only option for the most demanding parts.
Repeatability
This represents a crucial advantage for industries that require a large number of precision parts. When assembling products in large quantities on the production line, any size deviation will cause the entire production process to come to a halt.
Efficiency
Precision machining can be a highly efficient process. With modern machines and cutting tools, high-precision parts can be produced without incurring an increase in processing time.
Complex parts
This process offers extensive possibilities for manufacturing parts with complex shapes. Although there are some limitations, they are much smaller compared to other manufacturing techniques for parts.
Quality
The parts produced by this manufacturing technology are of high quality and durable. This is attributed to the precision of the process and the availability of various materials suitable for part manufacturing.
Automation
Due to the computer control of the machine tool, the entire process, from transporting the processing materials to the processing area to collecting the parts from the processing area, is highly suitable for automation.

The process of precision machining
Precision machining is a complex multi-step process whose ultimate goal is to achieve excellent quality in part manufacturing. The specific steps will vary depending on the type of part being machined. However, some basic steps can be summarized as follows:
Design
step is to create a detailed design drawing of the part to be processed. This design drawing will include the dimensions, shape, and tolerances of the part, among other specifications.
Programming
The next step is to create a program for the machine tools used to process the parts. This program contains instructions that guide the movement of the machine tools and the processing of the materials to create the desired parts.
Setup and Inspection
Before starting the processing, it is necessary to equip the machine tool with the appropriate tools and inspect the material to be processed to ensure it meets the specifications.
Processing
The processing procedure refers to the process where the machine tool, following the pre-set program instructions, cuts and shapes the material to ultimately obtain the desired shape and size of the part.
Inspection and Quality Control
After the processing is completed, the parts are inspected to ensure they meet the specifications and tolerance requirements. If necessary, adjustments are made and the parts are tested to verify whether they conform to the required quality standards.
