CNC machining is a subtractive manufacturing method that automates the removal of material
from raw stock using computer-generated instructions.
Typically, CNC machines fall into two categories: those that keep the raw stock stationary while
the cutting tool rotates and those that rotate the raw stock while moving it against a
stationary tool.
Various adaptations and combinations of these techniques exist to create parts with intricate
features.
Product Details
CNC machining is applied to a wide range of materials, each having its unique optimal machining
parameters (speeds and feeds) to ensure effective material removal.
The most frequently used materials include:
Metal
Metal is the most prevalent material in CNC machining. CNC machines can cut virtually any type
of metal, from easily machinable brass to challenging nickel superalloys like Inconel.
Metal machining spans various applications, including injection molds, shafts, and gears.
Plastic
Although most plastic parts are made through injection molding, CNC machining is employed for
specific plastic components. Common materials include ABS (acrylonitrile butadiene styrene),
nylon, and polycarbonate.
Plastic machining applications encompass valve bodies, bushings, and prototypes for evaluating
part functionality before investing in costly molding tools.
Wood
CNC routers are frequently used for wood cutting and are generally more cost-effective than
standard metal-cutting CNC machines. Wood CNC machining is primarily employed for decorative
purposes. Typical applications encompass furniture, window frames, and ornamental panels.
Foam
Polyurethane foam, whether closed or open-cell, finds extensive use in CNC machining.
Foam blocks can be shaped into secure packaging for high-value products using a CNC router.
One example is the foam employed in toolboxes to securely hold tools during transport.
Composites
CNC machines are commonly employed in the processing of composite parts.
Composite materials include a wide range, from aramid to fiberglass to carbon fiber.
These materials are highly abrasive to cutting tools.
In aerospace and marine industries, composite components are machined to add fastener holes
and for general trimming post-molding.

FAQ's
1. Why choose CNC machining?
CNC machining offers speed, precision, and versatility that stand out among manufacturing
solutions.
It can produce end-use parts in any quantity without requiring significant investments in hard
tooling or costly setups.
2. What tolerances can I achieve with CNC machining?
Our standard tolerances for CNC machining are 0.05 microns, suitable for most commercial
and industrial applications.
For projects with more stringent tolerance requirements, please consult with us to discuss
your specific needs.
3. How long does delivery time and quotation take?
Our delivery time and quotation process are influenced by the complexity of your project.
For low-complexity parts, expect a lead time of 2-3 days.
As complexity increases, the lead time can range from 2-5 days.
High-complexity parts may require a lead time of 5-15 days.
Quotation turnaround time varies based on complexity as well.
For straightforward designs, we can provide a quote within 1 business day or even faster.
However, for more intricate projects, the quoting process may take 3 or more business days.
If you have a design that needs assessment and a quote from our team, please don't hesitate
to contact us.
4. What industries do you typically work in? Who are your typical customers?
Our extensive experience spans a wide array of industries, making it challenging to pinpoint those
we haven't served.
