CNC Machining Services

Rapid prototyping via CNC machining delivers high speed, high precision, and robust rapid part manufacturing solutions. You take a block or billet of material and cut away at it with a series of tools and drill bits, removing material to make CNC machined parts or products.
As a pivotal process in contemporary manufacturing, CNC machining has become indispensable in industrial production due to its high precision, efficiency, and excellent repeatability. The technology primarily includes the following major processing types, each with unique characteristics.

CNC milling cuts shapes out of a metal or plastic material blank that is usually flat, holding dimensions to tolerances as tight as 0.002”.

Processing Principle

Workpiece rotation with linear tool feed

Key Features

Primarily processes rotational parts Capable of external cylindrical, internal bore, face, and thread machining

Material Selection for CNC Machining

In CNC precision processing, the selection of materials directly affects the performance, processing difficulty and final quality of the parts. The following are the characteristics of common CNC processing materials:

Aluminum alloy

Characteristics:

Lightweight: Density is only 1/3 of that of steel

Easy to process: Excellent cutting performance, low tool wear

Rich surface treatments: Suitable for processes such as anodizing and sandblasting

Stainless Steel

Characteristics:

Corrosion Resistance: 316 contains molybdenum, offering stronger resistance to acids and alkalis

High Strength: However, it has a significant tendency towards work hardening

Surface Fineness: Can be mirror-polished to Ra0.2μm

Titanium Alloys

Characteristics:

High specific strength: Strength is comparable to that of steel, yet the weight is 45% lighter.

Biocompatibility: Preferred for medicalimplants.

Resistant to extreme environments: Stable at -253℃ to 600℃.

Tool Steel

Characteristics:

Ultra-high hardness: HRC 58-62 (after heat treatment)

Wear resistance: Suitable for long-term friction conditions

Dimensional stability: Heat treatment deformation < 0.1%

Engineering Plastics

Characteristics Comparison:

Material / Temperature Resistance / Friction Coefficient / Medical Grade Certification

PEEK / 260℃ / 0.3 / FDA / ISO13485

PTFE / 250℃ / 0.05 / USP Class VI

CNC Machining Applications

From micron-level medical devices to massive aerospace components, CNC machining technology is pushing the boundaries of modern manufacturing. This revolutionary technology, driven by computer-controlled precision, transforms metals, plastics, and composite materials into high-precision engineered parts, with applications spanning every industrial sector.

In the aerospace industry, 5-axis CNC machines produce aerodynamically optimized turbine blades. Automotive manufacturing relies on CNC lathes to mass-produce engine core components with 0.01mm precision. The medical sector utilizes micron-level CNC equipment to manufacture artificial joints and surgical instruments. From precision heat sinks in electronics to complex cavities in communication base stations, and heavy structural components in energy equipment—CNC machining enables batch production of precision parts across industries.

With the advancement of smart manufacturing, CNC machining centers are now integrating with robotics, 3D printing, and other technologies to build flexible production lines. From prototyping to large-scale production, CNC technology continues to deliver precise and efficient manufacturing solutions, solidifying its role as an indispensable core competency in high-end manufacturing.
