Custom Machined Metal Parts CNC Parts Machining Stainless Steel Milling Parts

CNC machining is a subtractive manufacturing process, meaning it achieves its final product

by removing material. It involves tasks like drilling holes, creating slots and pathways, and

shaping metal stock into different forms with varying dimensions and designs.

Unlike additive manufacturing, which builds up materials layer by layer, CNC machining

subtracts material to create shapes. It also differs from injection molding, where material

is injected into a mold to form a specific shape.

CNC machining is highly versatile and compatible with a wide range of materials, including

metals, plastics, wood, glass, foam, and composites.

This versatility has made CNC machining a popular choice in various industries, offering efficient

and precise fabrication for designers and engineers.

Product Details

CNC machining can be used for a wide variety of materials, with the most common being aluminum,

steel, brass, ABS, Delrin, and nylon. But really, almost any hard material can be CNC machined.

Here is a comprehensive overview of the most popular materials.

What Are the 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

printedcircuit 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.

7 Key Advantages of CNC Machining

1. Minimal to Zero Material Waste: CNC machining stands out for its efficiency and the minimal

wastage it generates. Thanks to its precision and accuracy, properly designed parts rarely result

in faulty cuts, significantly reducing the need to discard damaged components.

CNC machines excel at precise cuts and angles, minimizing material waste.

2. Exceptional Accuracy and Defect-Free Results: Precision is one of the primary benefits of CNC

machining. With precise computer instructions guiding the process, CNC machines consistently

produce identical, closely matching results.

This accuracy is especially valuable for creating parts with tight tolerances, virtually eliminating

human errors.

3. Rapid and Efficient Production: CNC machining offers remarkable speed and efficiency in

production. These machines can manufacture products at a much faster rate than traditional

methods, and some can even load and unload billets without human intervention.

This leads to substantial cost savings and increased productivity while ensuring consistent part

quality.

4. Faster Assembly: Components produced through CNC machining are easier to assemble.

Thanks to the precision and consistency of CNC processes, companion parts fit together

exactly as designed in the computer model.

The quick machining process reduces waiting time for completed parts, streamlining the

assembly process with minimal need for extensive fitting and adjustment.

5. Enhanced Safety: CNC machining enhances safety in manufacturing by removing significant

risks from the shop floor. Automation eliminates many hazards associated with manual

machining, and the enclosed nature of CNC machines further reduces the risk of injury.

6. Reduced Energy Consumption: CNC machining is energy-efficient, using significantly less

electricity compared to older manufacturing processes. According to the EPA, CNC machining

consumes only about one-seventh of the energy used by traditional methods.

The combination of speed and lower power consumption makes CNC machines environmentally

friendly.

7. Lower Production Costs: CNC machining is cost-effective, efficient, and precise.

It also utilizes fewer raw materials compared to conventional machining.

Transitioning to CNC technology can lead to reduced errors, lower production expenses,

and ultimately lower product costs, making it an economically attractive choice for

manufacturing parts and products.
