CNC machining is presently the prevailing subtractive manufacturing technology, offering a highly
adaptable and sturdy method for crafting tailored metal and plastic components.
Employing CAD models, CNC machines meticulously eliminate material from a solid block using
various cutting tools.
In essence, CNC machining yields components with precise tolerances and remarkable material
characteristics.
It is well-suited for individual projects and moderate-volume production (up to 1,000 parts)
owing to its exceptional repeatability. Nevertheless, it entails more design constraints compared
to 3D printing, partially attributable to the subtractive nature of the technology.
Product Details
CNC machining machines exhibit the capability to cut a diverse range of materials, including
aluminum, bronze, copper, ceramics, plywood, various steel alloys, stone, wood, zinc,
and other engineering materials. This versatility makes CNC machining an ideal choice for
generating prototypes in product development. It enables precise and rapid adjustments until
achieving the desired end product.
