Precision machining in CNC involves achieving high precision and tight tolerances for parts with complex geometries and excellent surface finishes. Advanced tooling and thermal management are critical to maintaining accuracy, especially for miniaturized components. Materials like aluminum, stainless steel, and titanium are commonly used for their dimensional stability and performance. Precision machining is essential in industries such as aerospace, medical devices, electronics, and automotive, where quality assurance is paramount.

1. Material Selection
Aluminum (e.g., 6061, 7075): Lightweight, excellent machinability, and good thermal conductivity.
Stainless Steel (e.g., 304, 316): High strength, corrosion resistance, and durability.
Titanium (e.g., Grade 2, Grade 5): High strength-to-weight ratio and corrosion resistance.
Plastics (e.g., PEEK, Delrin): Lightweight and electrically insulating, suitable for non-conductive applications.
Copper Alloys (e.g., C11000): Excellent electrical and thermal conductivity.
2. Machining Challenges
Tight Tolerances: Typically within ±0.01 mm or tighter.
Complex Geometries: Intricate designs with thin walls, small features, and tight clearances.

Feed Rate (f): 0.02-0.1 mm/tooth (lower for finer finishes).
Depth of Cut (ap): 0.5-2 mm (adjust based on material and tool rigidity).
Coolant: Essential to prevent overheating and improve tool life.
5. Surface Finish
Typical Ra Value: < 0.8 µm (often < 0.4 µm for functional surfaces).

Precision machining is a manufacturing process in which raw materials are processed into parts or products with tight dimensional tolerances, complex geometries and excellent surface quality through high-precision equipment and technology. Its core objective is to achieve micron-level (μm) or even nanometer-level (nm) precision, and it is widely used in high-end manufacturing fields.

Its core objective is to achieve micron-level (μm) or even nanometer-level (nm) accuracy, widely used in high-end manufacturing areas, our company has a high-precision five-axis machining process and high-precision testing equipment, which makes our products processed with an accuracy of up to ± 0.01 per cent.

Design and process analysis: use CAD software to design the 3D model of the part, carry out processability analysis, and clarify the size, shape, surface roughness and tolerance requirements.
CAM programming: import the CAD model into the CAM system, plan the tool path, set cutting parameters (such as spindle speed, feed rate, depth of cut, etc.), to generate G-code programme.
Machine setup and test cutting: choose the appropriate CNC machine (such as CNC lathe, CNC milling machine, etc.), clamp the workpiece, install the tool, zero calibration, and test cutting and simulation to verify the correctness of the program.
Formal machining and post-processing: After formal machining, surface treatment, inspection and measurement are also required to ensure that the machining quality meets the design requirements.
This process ensures standardisation and precision from design to finished product.

3. Key technical parameters
Successful CNC services are dependent on the precise control of the following key parameters:
Spindle speed and cutting speed: depending on the diameter of the workpiece and material characteristics, the appropriate cutting speed is determined to ensure machining efficiency and tool life.
Feed rate: the speed at which the tool or workpiece moves, which directly affects surface quality and cycle time.
Cutting depth and back eating amount: the amount of material removed by each cutting needs to balance the machining efficiency and precision of the parts, to avoid vibration or heat accumulation caused by too deep cutting.
Cutting fluid use: Choosing the right cutting or cooling fluid can reduce temperatures, minimise tool wear and improve the machined surface.
Detailed parameter selection usually relies on cutting volume manuals and test cut data.
