CNC machining, or computer numerical control machining, stands as a widely utilized manufacturing
process employing automated, high-speed cutting tools to shape designs from metal or plastic stock.
Standard CNC machines encompass 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers.
The methodology for cutting CNC parts may vary across machines—where the workpiece or the
cutting tool may move independently or in unison.
Skilled machinists proficiently operate CNC machines, programming tool paths based on the final
machined parts' geometry. CAD (computer-aided design) models furnish the necessary part
geometry information.
CNC machines exhibit the capability to precisely and repeatedly cut various metal alloys and rigid
plastics, making custom machined parts applicable across diverse industries such as aerospace,
medical, robotics, electronics, and industrial.

CNC Machining Using Brass Material
Brass is a metal alloy known for its low friction properties, exceptional electrical conductivity,
and distinctive golden appearance.
This material offers good machinability, making it suitable for a wide range of applications that
demand low friction and high electrical conductivity.

FAQ's
1. Which design file formats does We support for quoting?
To facilitate accurate and timely quoting, we only acknowledge 3D CAD files in STL, STEP, or IGES
formats. For 2D drawings containing reference dimensions, we request submission in PDF format.
It's essential to provide comprehensive manufacturing information as part of the technical
documentation. Please note that informal communication channels such as SMS, Skype,
and email will not be considered valid for manufacturing purposes.
2. What tolerances can I achieve with CNC machining?
With CNC machining, our standard tolerances are set at 0.05 microns, catering to the needs of
most commercial and industrial applications. For special projects that demand even tighter
tolerances, feel free to consult with us. We are committed to accommodating unique requirements
and ensuring precision according to your specifications.
3. How much time does it usually take to receive a quotation?
Our standard practice involves responding to most Request for Quotation (RFQ) submissions within
a couple of days. Should there be any deviation from this timeframe, we assure you that we will
promptly communicate any delays.
4. Can I use my own material for production?
Yes, customer-supplied material is fine so long as it fits with our machine capabilities.
