Stainless Steel CNC Turning Machining Parts Custom Manufacturer CNC Machining
Service Aluminum Turned Parts
CNC turning is a machining process where a rotating workpiece is secured in a chuck or collet,
while cutting tools precisely remove material to achieve the desired shape.
The movement of the cutting tools is controlled along various axes through a computer numerical
control (CNC) system, enabling operations such as turning, facing, threading, and grooving.
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. CNC Turning Tolerances
Our tolerance for CNC turned parts is typically +/- 0.005 inches.
In some cases, we can achieve tighter tolerances, depending on the part's geometry and the
tooling used.
If your part requires a tighter tolerance than our standard +/- 0.005 inches, please inform us
during the quoting stage. Our team will evaluate your requirements and provide guidance on
available options.
2. Secondary Surface Finishing in CNC Turning
The CNC lathe production process often incorporates various secondary finishing techniques to
ensure that metal parts attain the desired surface quality after machining.
These secondary finishing services encompass tasks such as deburring, grinding, polishing,
anodizing, painting, and plating.
Deburring plays a crucial role in eliminating sharp edges or burrs, enhancing the overall safety
and functionality of the metal parts.
Meanwhile, grinding and polishing procedures are employed to refine and improve the surface
finish of the metal components, resulting in smoother and more aesthetically pleasing surfaces.
Furthermore, anodizing and plating techniques are utilized to enhance the strength, wear
resistance, and corrosion resistance of the metal, thereby extending the lifespan and durability
of the machined parts.
In cases where the machined part is metal, painting or powder coating may be applied to
introduce color and further customize the appearance of the component.
3. Delivery Time and Quotation Turnaround
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.
