How CNC machining works?

CNC machining (Computer Numerical Control Machining) is a manufacturing process in which machine tools and specialized cutting tools are pre-programmed and controlled by a computer. CNC machining can be used to control a variety of complex equipment, such as grinders, lathes, milling machines and cutting machines, etc.

Firstly, the structural parts are

designed through CAD or 3D software

, and then the computer program (CAM) is written based on the CAD and 3D software: The CAD drawings are converted into instruction codes recognizable by the CNC machine tool through CAM (Computer Aided Manufacturing) software. Subsequently, the machine tool will operate automatically according to the program to cut, drill, mill or turn the material, and process it into the required shape.

CNC Machining Capabilities

3-Axis Machining Service
✓
3-axis machining
is the most fundamental CNC numerical control machining method, where the tool only
moves in the X, Y, and Z directions
. It is suitable for parts with simple structures and flat surfaces, and the processing depth is limited.
5-Axis Machining Service
✓
5-axis machining
adds
two rotational axes
(usually the A axis and the C axis or B axis) on the basis of the traditional X, Y, and Z axes, allowing the tool to process the workpiece from almost any Angle. It is suitable for parts with complex curved surfaces and high precision requirements, and can complete multi-faceted processing in one clamping.
CNC Turning Machining Service
✓
CNC Turning machining
is a high-precision rotary processing technology that controls machine tools through computer programs, mainly used for the production of cylindrical, conical and other axisymmetric parts.

ISO 14001:2015ISO 14001 certification drives us to practice sustainable manufacturing, with green production as the core goal. We optimize cutting parameters to reduce the waste rate. The recovery rate of aluminum chips reaches 95%, and the coolant circulation system reduces hazardous waste emissions by 30%.
The upgrade of high-efficiency equipment has reduced energy consumption (case: annual electricity bill savings of 80,000 yuan), meeting the ESG audit standards of European and American customers.

ISO 9001:2015Through ISO 9001 certification, we have established a closed-loop of full-process quality management: from drawing review to finished product inspection, precise control is achieved. The standardized process ensures that the dimensional tolerance of parts is stable (±0.02mm), and the surface finish reaches Ra1.6μm. First Piece Inspection (FAI) and Process Monitoring (SPC) intercept batch defects. For example, in the processing of a certain medical part, the defect rate was reduced to 0.15%.

CNC Machining Tolerance Standards

There are many types of errors that can be caused by CNC machining services, such as the hardness of the material, tool wear, and even the temperature during processing, all of which increase the probability and range of errors during processing.

Accuracy level	Typical tolerance range	Applicable field
Commercial grade	±0.1mm	General mechanical components
Precision grade	±0.025mm	Automobile engine components
High precision level	±0.005mm	Optical instruments/medical implants
Ultra-precision level	≤±0.001mm	Semiconductor molds/aerospace components

CNC Machining Frequently Asked Questions

Which processing types are supported?

There are many types of CNC machining, including turning (for shaft parts), milling (for complex three-dimensional parts), drilling, tapping, engraving, etc. 3-axis to 5-axis machining is available.
What are the differences between CNC and traditional processing?

Unlike traditional processing, which relies on manual operation, CNC is controlled through program automation, offering higher precision (±0.02mm) and greater efficiency. It is suitable for complex parts and large-scale production.
What is CNC numerical control machining?

Simply put, CNC machining is a technology that controls machine tools to automatically cut materials through programming. It is suitable for the manufacturing of precision parts made of metals, plastics and other materials, featuring high accuracy and good repeatability.
Could you provide the material certification documents?

Support! Such as SGS reports for stainless steel, biocompatibility certificates for medical titanium alloys, etc.
