Get instant quotes on metal and plastic machined parts , low-cost, CNC parts from a network of manufacturers across China.
Unionfab provides precision CNC services, including Machining, Milling, and Turning. Unionfab works with an extensive network of manufacturing partners that have over 1,000 machines, which means we always have the capacity and very competitive prices. In addition, we support 3-axis, 4-axis, 5-axis, and right-angle capabilities to help you rapidly create designs from simple straight lines to complex geometric shapes.
It is a broad manufacturing category that includes many different computer-controlled processes where raw material is selectively removed in exact amounts to produce a near-final shape of parts. That’s why it’s considered subtractive instead of additive manufacturing or 3D printing. Online CNC machining services include milling, turning, surface grinding, and electrical discharge machining (EDM), although there are other specialized applications. Whenever a machine is digitally controlled, there must always be a 3D CAD file of the part design used to program the machine’s movements.
Unionfab provides custom CNC machining services to engineers, product developers, designers, and more. We work with an extensive network of manufacturing partners that together have over 1,000 milling machines, which means we always have the capacity and very competitive prices. We offer rapid CNC prototypes, small-batch machining, and high-volume production, with all orders serviced by Unionfab from end to end. Upload a CAD file to the Unionfab Instant Quoting Portal to get a price, lead time, and design-for-manufacturability feedback on your custom CNC parts.
Like CNC mills, CNC lathes can be easily set up for high repeatability, which makes them great for everything from rapid prototyping to low and high-volume production. Multi-axis CNC turning centers and Swiss-type lathes allow for multiple machining operations in one machine. making them a cost-effective option for complex geometries that would otherwise require multiple machines or tool changes in a traditional CNC mill.
CNC milling is a form of subtractive manufacturing in which raw material is processed through the use of computer-controlled, automated machinery.
Using advanced CNC milling machines, we produce high-quality parts for a wide range of applications in the aerospace & defense, automotive, electronics, and other demanding industries.
Our technicians are highly-skilled operators and our organizational focus on quality and customer satisfaction at every level enables us to produce the precision parts you require for your project.
