Rapid CNC machining is a subtractive manufacturing process that works best for prototyping, form and fit testing, jigs and fixtures, and functional components for end-use applications. Proto Labs manufacture parts through high-speed milling and turning processes from more than 30 different engineering-grade plastic and metal materials.
During the milling process, a solid block of material is clamped into a CNC mill and cut into a finished part. Proto Labs employ three-axis milling from up to six orthogonal sides of the part to machine as many features as possible. The range of material choices allows parts to be made with the desired material properties, and good tolerances yield parts suitable for form, fit and function testing.
During the turning process, rod stock is rotated on a CNC lathe while a tool is held against the stock to remove material and create a cylindrical part. Live tooling is available so features like axial and radial holes, flats, grooves, and slots can be machined. Proto Labs’ range of metals, including soft metals and steel, allows parts to be made with the desired material properties, and good tolerances yield parts suitable for form, fit and functional testing.
In part one of Proto Labs’ three part series, Saleem Shariff - Lead Customer Service Engineer, discusses what value CNC machining could bring to your project and provides insightful tips about how you can use CNC machining to increase manufacturing efficiencies and reduce costs.
