What Is CNC Precision Machining

Precision CNC machining is the most accurate, fastest, and efficient way to create machining parts which usually is hard plastic and metal materials.

Precision CNC machining is a process that machines use computer-aided manufacturing (CAM) or computer-aided design (CAD) to create high complexity and tight tolerance parts which raning from +/- 0.001mm to +/- 0.02mm. These technologies are state-of-the-art that can make the parts are meet design specific and exact dimensions on the CAD drawings.

These precision machines incluing of CNC Milling, CNC turning, CNC lathe, CNC router, WEDM, plus EDM and Grinding to cut or drill metal work-pieces with extreme accuracy to final precision desired parts. The process has been around for decades but it has only been in the past 10 years that it has become more popular because of the accuracy and precision of modern machines, and it is especially popular for automotive and aerospace industrials.

Types of Precision Machining Equipments

Precision CNC machines are a type of machine that is used in manufacturing to create precise parts and products. There are 3 main types of precision CNC machines, which are the following:

(1). 3 axis cnc machine

A 3-axis CNC mill is a machine tool that can cut, form and shape a material. A 3-axis CNC milling machine is designed to perform the operations of machining, milling and drilling. It works by moving the cutting tool in all three axes (X, Y, Z). The movement in each axis is controlled by servo motors or stepper motors.

(2). 4 axis cnc machine

A 4 axis CNC milling machine is a device that can be programmed to perform a wide range of operations, including cutting, drilling, and engraving. The machine has four axes of movement: x-axis, y-axis, z-axis and rotary axis.

A 4 axis CNC milling machine is generally used in manufacturing. It can be used for the machining of parts made from various materials such as steel or aluminum.

(3). 5 axis cnc machine

A 5 axis CNC machine is a machine that can move in 5 different axes. This means that it has the ability to move in any direction, making it much more versatile than a 3-axis and 4-axis machine.

A 5-axis machine is a milling machine that can move the cutting head in any of the three rotational axes, and also along two linear axes. The tool head moves on 2 or 3 parallel rails, each with an axis of rotation perpendicular to the other two.

How can I improve my CNC accuracy?

  1. You need good experience cnc  machinist whom has good cnc programming skills and familiar with different materials & cnc machining techniques. CNC programming is the most basic work of cnc machining for any parts.
  2. Choose the right machining machine to make the parts, the principle is less complexity and less labour work, but a good skills & experience cnc operator can make more precision parts with simple cnc machine then a new cnc operator.
  3. Measure and adjust the machine system at the best level, we need to do a good job for machinery maintain everyday so it can process well and smoothly during machining.
  4. Reducing the measurement errors, it relys on good experience inspector and high precision measurement tools.
  5. Reducing tool wearing, choose right tools, and replace wearing tools in time.
  6. Reducing the thermal deformation of the process system.

Types of CNC Precision Machining Services That We Offer



Using imported multi-axis milling machines from the United States and Japan, as well as the top brand from China, we can guarantee CNC milling parts that are within the tolerance of +/-0.05mm, while also keeping critical dimensions under +/- 0.005mm.

Our team also has extensive experience creating precision parts for some of the most demanding industries in the world, including aerospace and medicine.

The 5-axis CNC milling machines come with an on-site inspection system that allows us to monitor the actual dimensions of a part during the milling process. The computer is able to automatically adjust the program and parameters to ensure that the parts are manufactured correctly.


Unlike CNC milling, the CNC turning process uses a single-point cutting tool to create precise cylindrical cuts into a rotating material. This automated technique provides great accuracy and a high degree of repeatability and is ideally suited for manufacturing circular or tubular shapes. The CNC turning lathe secures and rotates the material as its machined at high speeds.

Our expert technicians are able to achieve incredible accuracy when producing components because of the professional-grade CNC turning machines that we have available.

While CNC milling is ideal for short-run volumes of prototypes and parts that are below 2.5” OD, CNC turning machines are better-suited for short-run volumes of larger parts above that threshold.

Common applications for CNC turning include functional prototypes, spacers, manifolds, fittings, shafts, and bushings.
