What is precision machining

Precision machining refers to a machining technology with a machining accuracy of 1~01μm and a surface roughness of Ra01~001μm. However, this precision limit will continue to change with the progress of processing technology. Today's precision machining may be tomorrow's general Processing. The problems to be solved by precision machining are machining accuracy, including form and position tolerance, dimensional accuracy and surface condition; and machining efficiency. Some machining can achieve better machining accuracy, but it is difficult to achieve high machining efficiency. Precision machining includes processing technologies such as micro-machining, ultra-fine processing, and finishing. Traditional precision machining methods include belt grinding, precision cutting, honing, precision grinding and polishing.

Precision machining can be used with a number of raw starter materials including (but not limited to) plastic, ceramic, metal, composites, steel, bronze, graphite, and glass. In order to make precise cuts and intricate removal of the raw material, a combination of tools may be used. These tools vary depending on the raw material. Frequently used tools include milling machines, lathes, Electric Discharging Machine (aka. EDM’s), saws, and grinders. Most commonly used manufacturing equipment is computer controlled heavy machinery that is designed and utilized to remove substrate material creating finely detailed components and piece parts. In some cases, even high-speed robotics and photochemical processes may be used to achieve the desired result for the final product.



Precision machining is a subtractive process where custom software, engineered tools, and process steps are utilized with raw material such as plastic, ceramic, metal or composites to create desired fine-featured products. Precision machining often follows the instructions given by computer aided design (CAD) and computer aided manufacturing (CAM) programs. These programs and the blueprints enhance the ability to meet tight tolerances. While most designs end up as engineered and computer aided designs, many start out as hand drawn sketches in the initial phases.


The role of precision machining

Components, parts and finished durable products that are designed to maintain extremely tight tolerance margins and a high degree of durability are essential and common drivers for utilization of precision machining. For example, parts that need to work together as part of a machine may need to always align within a certain margin of 0.01mm to 0.05mm. Precision engineering and machining help to ensure these parts can not only be made precisely but can be produced with this level of accuracy over and over again.

The role of precision machining

CNC precision machining and manufacturing

In the processing industry, especially CNC precision parts processing pay attention to precision, which is the basic requirement.
1. Multi-axis control and multi-axis linkage: most commonly used machining centers are three-axis linkage. By increasing the swing angle and increasing the rotation coordinates, it can form four-axis linkage, five-axis linkage, seven-axis linkage, and even more-axis linkage processing. center.
2. Parallel machine tools: The functions of commonly used machining centers are relatively fixed. Vertical machining centers, horizontal machining centers, or machining centers, turning centers, etc. are combined to form a processing system, which increases the processing range and processing capacity of the machine tool.
