CNC Machining Stainless Steel Turning Service CNC Custom Aluminum Mechanical
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.

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.
