3-Axis CNC Machining Principles

3 axis CNC machining service

is a service that relies on high-precision CNC machine tools and mature processes, specializing in customizing precision metal and plastic parts. The technology of controlling tool paths and the linkage of the X, Y, and Z axes through

computer programming

(G-code /CAM) enables efficient processing of complex geometries, meeting diverse demands from prototype development to

mass production

Shengyi Intelligent Technology specializes in providing a series of CNC numerical control processing with a X×Y×Z=600×400×400mm stroke. Whether it is 3-axis or 5-axis, the company can provide efficient and high-quality products. We support services such as rapid sample production and early-stage product design and development.

3-Axis CNC Machining Application

Precision Small Parts Processing

✓ In the
electronics industry
, for example, the base of a
heat sink
(with dimensions of 80×60×15mm and aluminum alloy 6061) often requires CNC machining. It is usually composed of thin-walled fins with a thickness of 0.5mm. It also features a porous structure (φ2mm through hole array), but the traditional production method often leads to deformation and burrs. If 3-axis cnc machining is used and fixed with dedicated fixtures, with step-by-step cutting to control thermal deformation, the product can also achieve a surface finish of Ra1.6.

✓ In the
medical device industry
, for example:
metal sleeves
for endoscopes (outer diameter φ8mm× length 150mm, stainless steel 316L). Specific requirements: micron-level coaxiality (≤0.03mm), mirror polishing of the inner wall (Ra0.8). By customizing micro turning tools and high-speed precision turning, combined with the inner hole grinding process.
Small and Medium-Sized Functional Structural Components

✓ In the
automotive industry
, for example:
transmission sensor bracket
(120×80×25mm, POM engineering plastic)

✓ Specific requirements: Lightweight design + high dimensional stability (±0.05mm), compatible with high-temperature environments.

✓ It is formed in one go through 3-axis cnc machining milling, optimizing the tool path to reduce stress, and then undergoing post-treatment deburring and anti-static coating to meet the requirements.

✓ In
industrial equipment
, for example:
pneumatic valve body
(dimensions 200×150×50mm, brass H59).

✓ Specific requirements: Multi-step inner hole (tolerance H7) + cross-threaded hole (M6×M8), the flatness of the sealing surface ≤0.02mm.

✓ By designing compound processing (turning + drilling + tapping), special thread cutting tools ensure the fit accuracy.
Rapid Prototype Verification Across Multiple Industries

✓ In
consumer electronics
, for example:
metal frame of smartwatch
(dimensions 45×38×10mm, aluminum alloy 7075)

✓ Specific requirements: Curved surface transition (R Angle 0.3mm) + antenna slot (width 0.8mm), 5 prototypes for verification.

✓ Through 3-axis cnc machining high-speed precision engraving, delivery within 48 hours, and support for structural optimization and iteration.

✓ In the
field of robotics
, for example:
collaborative robot joint connectors
(dimensions 180×100×30mm, titanium alloy TC4)

✓ Specific requirements: weight reduction and hollowed-out design + high rigidity requirements, surface anodizing treatment.

✓ Deformation is controlled through layer-by-layer milling, and the adaptability of the post-treatment process is verified by simulation.

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%.
