Post-processing and surface finishes for CNC machining
CNC-machined parts as they emerge from the machine often exhibit visible tool marks,
a feature that may not align with your specific part requirements.
Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the
surface appearance and elevating attributes such as wear resistance, corrosion resistance,
and chemical resistance.
Methods like anodizing, bead blasting, and powder coating present viable options for refining
the final presentation of your custom parts, allowing you to achieve the desired surface
quality and performance characteristics.

Application
The possibilities for CNC machining applications are virtually limitless.
Here are a few examples:
1. Woodworking: CNC machining is utilized in the production of wooden furniture to save time
and reduce costs. It enables the creation of intricate furniture designs that would be impractical
to craft manually.
2. Lettering and Engraving: CNC machines can perform precise engraving tasks, whether for
artistic purposes or to mark serial numbers and patterns on surfaces.
3. Electronics: CNC machining is essential in the electronics industry for tasks like creating
mounting holes in printed circuit boards and machining heat sinks for electrical components.
4. Pharmaceuticals: CNC machines manufacture precise equipment for pharmaceutical production,
including metering pumps, dispensing nozzles, and packaging machinery.
5. Food and Beverage: The fast-moving consumer goods industry relies on custom
material-handling machinery with CNC-machined components. Additionally, CNC machining is
used to create molds for injection-molded food packaging materials.

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.
2. How to Accelerate CNC Manufacturing?
Various elements influence the pace of manufacturing, encompassing part design and desired
surface roughness.
Incorporating fillets instead of sharp corners serves as an excellent illustration of how design
adjustments can expedite the machining process.
This choice enables the production of the part using standard tools, eliminating the need for
tool changes during machining.
3. How to Lower the Cost of Machined Parts?
The expenses associated with CNC machining primarily encompass machining time, start-up costs,
material expenses, and feature-related costs.
To minimize costs, it's essential to grasp the impact of these factors.
1. To reduce machining time, opt for design features that can be machined swiftly.
For instance, choose appropriate radii for internal corners, limit cavity depth, increase wall
thicknesses, shorten thread length, and incorporate holes with standard sizes.
2. Cut material costs by considering the necessary blank size and assessing the cost and
machinability of the base material. Softer alloys tend to be faster to machine.
3. Mitigate start-up costs by minimizing the number of part rotations or repositioning steps
needed to complete the part.
This can be achieved by segregating geometries into multiple parts that can be assembled later.
4. To lower feature costs, employ tolerances only when absolutely necessary, eliminate any text or
lettering, and avoid multiple surface finishes whenever possible.
