Our CNC Milling Capabilities
RapidDirect provides 3 axis, 4 axis CNC milling, and 5-axis CNC milling centers according to your custom needs, from rapid prototyping to production parts.
3-axis, 4-axis CNC Milling
3-axis and 4-axis CNC milling machines are the most commonly used CNC milling process, which has lower tolerance level, but more affordable price. We recommend 3-axis or 4-axis CNC mill machining for producing parts with simple geometries.
5-axis CNC Milling
5-axis CNC milling center represents the highest manufacturing capabilities that CNC milling service could reach. It has higher price, but significantly higer efficiency comparing with 3-axis CNC milling, more suitable for producing parts with complex geometries.
Materials for CNC Milling Parts
The various available materials is another advantage of CNC milling. At RapidDirect, you can choose from over 50 milling metals and plastics. In addition, we also provide material certification at your request.
Aluminum is a highly ductile metal, making it easy to machine. The material has a good strength-to-weight ratio and is available in many types for a range of applications.
Copper displays excellent thermal conductivity, electrical conductivity and plasticity. It is also highly ductile, corrosion resistant and can be easily welded.
Brass / Bronze
Brass has desirable properties for a number of applications. It is low friction, has excellent electrical conductivity and has a golden (brass) appearance.
Steel is known for its high tensile strength and low costs. It is a ubiquitous material in the construction, infrastructure, automotive, maritime, tooling, manufacturing and defense industries.
Stainless steel typically contains a minimum of 10% chromium by weight. It is a popular metal within a broad range of industries, including construction, automotive, aerospace and more.
Titanium is resistance to corrosion, chemicals and extreme temperatures, and has excellent strength-to-weight ratio. It has broad adoption in the aerospace, medical and defense industries.
Plastic is an indispensable part of our everyday world. It is known for its lightweight, high strength-to-weight ratio, electric insulation, low price, suitable for mass production, etc. The application of plastics is so wide that you can always see it in all industries.
Surface Finishes for CNC Milling
CNC milling parts are left as-milled, and surface finish can change the appearance, surface roughness, hardness and chemical resistance of the produced parts. Determined by the material using, a part can have one to serval available surface finishing options. Learn more at our surface finish page.

What is CNC Machining
About the CNC Process
CNC, or computer numerical control machining, is a subtractive manufacturing method that leverages a combination of computerized controls and machine tools to remove layers from a solid block of material. The desired cuts in the metal are programmed according to corresponding tools and machinery, which perform the machining task in an automated fashion.
