CNC Machining Applications
CNC milling is employed to fabricate products composed of glass,
metal, plastic, wood, and
custom-designed components.
Machinists utilize this process to create prototypes and items for
various industries, including
aerospace, automotive, hardware startups, manufacturing, medical
devices, robotics, and others.

FAQ's
1. 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.
2. How does you ensure part quality?
Upon order confirmation, we conduct a comprehensive Design for
Manufacturing (DFM) review
to identify and address any potential issues that could impact part
quality.
We meticulously inspect and verify incoming materials using
advanced testing equipment.
We provide final inspection reports prior to shipment.
Our real-time inspection data sharing capabilities allow us to
collaborate with you in addressing
any quality concerns that may arise during production.
3. Advantages of CNC Machining
1. Fast and Repeatable
Quick removal of large amounts of metal material, parts ready as
fast as 1 day
2. Accuracy
High-precision tolerances ranging from +/-0.005″ – 0.01″, depending
on customer specs.
3. Wide Range of Materials
Choose from over 50 metal and plastic materials.
4. Scalable Volume
CNC Machining has scalable volumes for production of 1-100,000
parts.
5. Custom Surface Finishes
Suitable for many different kinds of substrates, make your parts
just the same as real products.
6. Cost Saving
Low investment in tooling and preparation costs, economical for
parts with simple structure.
