Turned Milled Part CNC Copper Brass Machining Part

 

CNC machining is a subtractive manufacturing method employed to fabricate parts by cutting away

material from a workpiece or stock.

 

Precise instructions in the form of preprogrammed software and codes are input into the machine

to govern the movement of its tools and equipment.

 

CNC machining encompasses various machinery types, including turning mills, lathes, grinders,

and plasma-cutting machines.

 

Product Details

 

Almost any rigid solid can be machined, including mild and stainless steels, aluminum, brass,

copper, magnesium, titanium, and many types of engineering plastics.

 

Common Metal Materials for CNC Machining
Metal MaterialProperties
Aluminum2024: 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 steelExcellent machinability and outstanding uniformity; good workability and weldability, high ductility and formability
Steel AlloyMix of chromium, molybdenum, and manganese yields toughness, good torsional and fatigue strength
BrassVersatile and highly attractive copper/zinc alloy with warm yellow color accommodates severe forming/drawing
CopperHigh ductility and high electrical and thermal conductivity; develops attractive blue-green surface patina over time
TitaniumExcellent strength to weight ratio, used in aerospace, automotive, and medical industries
Steel Mild Low CarbonHigh machinability and weldability, high stiffness; good mechanical properties, machinability, and weldability at low cost

FAQ's

 

1. What is CNC Machining?


CNC machining, short for computer numerical control machining, is a widely used manufacturing

process that employs automated, high-speed cutting tools to shape designs from metal or plastic

stock materials.

 

Common CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers.

These machines may employ different approaches to cut CNC parts, such as keeping the

workpiece stationary while the tool moves, keeping the tool stationary while rotating and moving

the workpiece, or moving both the cutting tool and workpiece simultaneously.

 

2. What tolerances can be achieved?


Tolerances are not standardized across all processes and materials. The final tolerances on your

part depend on various factors, such as part size, design complexity, the number and size of

features, materials used, surface finish, and the manufacturing process employed.

 

Once your order is confirmed, we conduct a Design for Manufacturing review to identify areas that

may need modification for better manufacturability.

 

It's helpful if you can specify which areas in your design have critical tolerances that must be met

and which can be adjusted, if necessary, to optimize production time and cost.

 

Here are some general tolerance guidelines:

 

General tolerances for CNC machining in metal and plastic.
Tolerances for plastic injection molding.
Reference charts for CNC machining of metals and plastic injection molding materials.
General tolerance for metal 3D printing is +/- 0.5mm.
A shrinkage rate of +/- 0.15% can be expected for vacuum casting.
All manufacturing and technical specifications must be clearly defined in the 2D drawings to be

followed accurately.

 

3. What are your shipping terms?


Our standard shipping terms are Ex Works (EXW) for both rapid prototyping and regular production

orders.

 

Under EXW terms, the customer is responsible for all aspects of shipping, customs clearance, and

associated fees once the goods have been dispatched from our facility.

 

For express shipments, we utilize Delivered Duty Unpaid (DDU) terms. This means that the client

is responsible for settling any import duties upon the goods' arrival at their designated destination.
