High Precision CNC Machining Service CNC Machining Turning Part CNC Machining
Part Stainless Steel Aluminum Milling Parts
CNC machining is a subtractive manufacturing process that automates the removal of material from
raw stock using computer-generated instructions.
Typically, CNC machines fall into two categories: those that keep the raw stock stationary while the
cutting tool rotates, and those that rotate the raw stock while moving it against a stationary tool.
Various machines incorporate these principles in different ways, often combining them to create
intricate parts with complex features.
Product Details
CNC machines are used on a vast array of materials. Each material has its own optimal set of
machining parameters (speeds and feeds) to successfully machine the material.
The most common materials are:
| Common Metal Materials for CNC Machining | |
| Metal Material | Properties |
| Aluminum | 2024: Good fatigue resistance and strength; excellent toughness at moderate to high strength levels; improved fracture toughness |
| 6061: Excellent machinability, low cost, and versatility | |
| 7075: High strength, hardness, low weight, and heat tolerance | |
| Stainless steel | Excellent machinability and outstanding uniformity; good workability and weldability, high ductility and formability |
| Steel Alloy | Mix of chromium, molybdenum, and manganese yields toughness, good torsional and fatigue strength |
| Brass | Versatile and highly attractive copper/zinc alloy with warm yellow color accommodates severe forming/drawing |
| Copper | High ductility and high electrical and thermal conductivity; develops attractive blue-green surface patina over time |
| Titanium | Excellent strength to weight ratio, used in aerospace, automotive, and medical industries |
| Steel Mild Low Carbon | High machinability and weldability, high stiffness; good mechanical properties, machinability, and weldability at low cost |

Company Profile
Benefits of CNC Machining
CNC machining offers several advantages, including:
1. Precision: CNC machines are capable of producing parts with exceptional precision, ensuring
consistent quality and eliminating human error.
2. Continuous Operation: CNC machines can operate 24/7 as long as they have a steady supply
of raw materials and fresh cutting tools.
Robotic systems can be employed for material loading and part unloading without the need for
human intervention.
Applications of CNC Machining
CNC machining offers a wide range of applications across various
industries. Here are some examples:
1. Woodworking
CNC machining is commonly used in woodworking to create intricate
and cost-effective wooden
furniture.
It allows for the production of complex designs that would be time-consuming and expensive when
done manually.
2. Lettering and Engraving
CNC machines can perform precise engraving and lettering tasks,
whether for artistic purposes or
marking serial numbers and patterns on parts.
3. Electrical Industry
The electrical industry relies on CNC machining for tasks such as
drilling mounting holes in printed
circuit boards and crafting heat sinks from aluminum or copper for electronic components that
generate heat.
4. Pharmaceutical Industry
In the pharmaceutical sector, CNC machines are employed to
manufacture precision equipment used
in pharmaceutical production.
This includes metering pumps, ingredient-dispensing nozzles, and packaging machinery.
5. Food and Beverage Industry
The fast-moving consumer goods industry benefits from custom
material-handling machinery,
often incorporating CNC machined parts.
Additionally, CNC machining is used to create molds for injection-molded food packaging materials.
