What Is Precision CNC Machining?

CNC precision machining involves the process of making parts with tight tolerance and complicated geometric details by cutting and shaping raw materials. Computer-aided Design (CAD) and Computer-aided Manufacturing (CAM) blueprints help instruct the proper cutting process. These programs are essential and indispensable during the design phase as they often contain detailed 3D contours to ensure successful part building.

High-precision machining now plays a significant role in the manufacturing industry, which needs the cooperation of highly skilled designers and engineers. Designers created designs at first and then transferred them into manufacturing instructions. The machinists then send the final coded instructions in machine language to the CNC equipment to start the manufacturing process.

Moreover, some core sectors require precise machining to manufacture components that function instantly and fit well into their assembly, such as surgical instruments, aerospace components, automotive accessories, optical parts, etc. The use of advanced precision machine tools in the precision machining process will facilitate the creation of complex parts with sophisticated geometries. A typical CNC machine can achieve a tolerance standard of +/- 0.005 inches. However, a tolerance of +/- 0.002 inches to +/- 0.0002 inches can be reached when using CNC precision machining.

Advantages of High Precision CNC Machining

Precision CNC machining can achieve higher productivity because it improves machining automation and programming capabilities without interrupting the use of the machine. High-precision machines with excellent accuracy offer repeatable results in good quality.

The CNC machine can run programs created offline while traditional machining involves manual monitoring and adjustment of tools and running speeds. One machine operator can do multiple works including changing over machining centers, running various productions, maintaining load parts and tools, and performing offline deburring and quality control.

Therefore, this structure doesn't need so many operators during the monitoring process, in turn, largely saving labor costs. Likewise, it speeds up the creation of parts.

The parts quality made from CNC precision machining is incredible. The use of computer numerical control eliminates any variation occurred in traditional machining.

The process can run for hours with minimal maintenance and advanced software to fit design requirements. Hence, even the most intricate parts can be manufactured with advanced processes to ensure the highest quality beyond customer expectations.

While some machining still uses traditional methods, some applications require high-precision machining to promise tight tolerances.

Additionally, most industries need to mass produce identical parts. This is only possible with the repeatability of precision CNC machining, ensuring that all parts maintain equal quality.

Your prototype production is even more efficient when employing CNC machining technology. You don’t have to spend a lot on prototypes since there are extensive cost-effective materials available for CNC machining. Certainly, the entire production process will speed up when prototyping is faster.

Types of CNC Machine

3-axis Milled Parts

3-axis Milling Machine

A 3-axis milling machine refers to manually milling a workpiece along the x-, y-, and z-axis. The 3-axis system remains stationary when the tool operates while other machines notably have a moving bed. These models are versatile and precise machines designed for well-defined holes and slots and the milling of sharp edges.

While this type of milling has the capability of producing the same product as 4- and 5-axis milling, 3-axis milling has a limited level of detail and efficiency compared to 4- and 5-axis machines.

4-axis Milling Machine

A 4-axis machine contains the same 3-axis’ mentioned above but adds a rotation around the X-axis, called the A-axis. While its capabilities are not comparable with more advanced 5-axis machines, it remains one of the most popular milling options and is well-suited for many designs, research, and prototyping.

Just one step away from the most advanced milling machines, 4-axis milling machines execute operations vertically and function in a high-volume fashion. These machines offer better capabilities than 3-axis machines with a higher level of detail handling.

4-axis Milled Parts
5-axis Milled Parts

5-axis Milling Machine

At present, 5-axis CNC machines are the milling machines with the highest efficiency and precision on the market. In addition to traveling along the x, y, and z linear axes, the 5-axis machine can rotate on two (A and B) axes, enabling the tool to approach parts from any direction.

Outperforming both 3-axis and 4-axis machines, 5-axis CNC milling machines can achieve incredibly complicated geometries with high precision. Runsom Precision has extensive experience in offering 5-axis CNC machining services that reach an angular tolerance of two in a thousandth of a degree (.002°) with outstanding surface finishes and quality at a rapid production run.

The basic concept of CNC precision machining is that it involves a manufacturing process employing software to design the exact specifications of a product, and then process the raw material into that “mold” to produce the finished product.

The standard tolerance limit for CNC machining is approximately +/- 0.005 inches (0.127 mm), while precision machining can reach +/- 0.0002 inches (0.00508 mm).
