Advantages of CNC Machining
CNC milling and turning are highly precise and repeatable processes that can achieve tight
tolerances ranging from +/-0.001″ to 0.005″, depending on specific requirements.
CNC machines can be programmed to operate reliably 24/7, making them ideal for on-demand
part production.
CNC machining services are especially valuable for creating custom CNC parts, whether it's for
replacing legacy components or delivering specialized upgrades to customers.
Additionally, CNC machining can efficiently scale from producing one-off parts to runs exceeding
10,000 units.
Turnaround times for CNC machined parts can be remarkably short, often as quick as one day,
and with shipping and delivery, deadlines can be met within a week.
Product Details
Another significant advantage of CNC technology lies in the mechanical properties it can achieve.
Unlike processes like injection molding or additive manufacturing, which may thermally transform
materials, CNC machining preserves all the desirable mechanical properties of the chosen metal or
plastic by removing material from the bulk.
CNC milling and turning can work with over 50 industrial-grade materials, including aluminum, brass,
bronze, titanium, stainless steel, PEEK, ABS, and zinc.
The primary requirement for CNC machining is that the material has sufficient hardness to be fixtured
and cut effectively.
Here is a comprehensive overview of the most popular materials.

Specialist Industries
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 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.

FAQ's
1. What Are the Benefits of CNC Machining?
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.
2. What are the Limitations of CNC Machining?
1. Skill Requirement: Operating and programming CNC machines is a complex task that demands
specialized skills, which can be expensive to acquire.
2. Cost: CNC machines are expensive due to their high precision and quality components.
Careful consideration of the current workload and potential return on investment is necessary before
making a purchase.
3. How Much Does CNC Machining Cost?
1. Material: The choice of material affects the cost, with some materials being more expensive to machine
due to tool wear and cutting speeds.
2. Complexity: Parts with complex features are more costly to machine compared to simpler designs.
3. Tolerances: Tight dimensional tolerances increase machining costs, so it's essential to specify them
only when necessary.
4. Surface Finish: Achieving mirror finishes requires specialized tools and strategies, which can add to the
overall cost.
5. Quantity: Low-volume production tends to be more expensive per part than large-volume production
due to setup and programming costs.
