Industrial Applications of CNC Milling
Speed of production, vast material options, and precise tolerances have made CNC milling a favored technology for on-demand manufacturing parts. We have been supplying CNC milled parts to various industries, including but not limited to the following.
What is the difference between a CNC router and a CNC mill?
CNC routers are designed for lower to moderate cutting speeds and are commonly used for softer materials such as wood, plastic, foam, and non-ferrous metals like aluminum. In contrast, CNC mills feature more robust spindles and higher horsepower, enabling them to cut through harder materials, including stainless steel, titanium, and composites, as well as softer ones.
While CNC routers are typically used for less precise, simpler machining tasks and can work on large workpieces, making them popular in industries such as woodworking and sign-making, CNC mills are adept at machining complex parts and producing high-precision components with tight tolerances. They are commonly employed in the aerospace, automotive, and medical manufacturing industries.
What is the difference between CNC cutting and milling?
CNC cutting, through methods like laser, waterjet, and plasma cutting, is designed for slicing materials to form external shapes or contours. This method is especially valuable for quickly handling large sheets, delivering high-quality edges with speed. It is a common step in sheet metal fabrication.
On the other hand, CNC milling is a more focused method of material removal from within, precisely removing material with rotating tools to create complex 3D shapes and detailed features in parts, suitable for high-precision components.
What types of cutting tools for milling?
There are many different types of cutting tools that can be used with CNC mills. End mills are the most common milling tools. They can cut along the tool's axis (axially) and across the diameter of the tool (laterally), with various end shapes such as square, ball nose, and corner radius, to produce different geometries.
Other common milling tools include face mills, which are used for creating flat surfaces; ball nose cutters, ideal for 3D contouring; chamfer mills, for making beveled edges; and dovetail cutters, used for cutting precise dovetail grooves.
What is CNC milling?
CNC milling is a subtractive manufacturing process that employs computer-controlled machines. It involves the use of a cutting tool mounted on a rotating spindle to remove material from a block, shaping it into the desired form.
