What Means CNC Machining?

What Is CNC Machining?

CNC Machining is a manufacturing technique for removing material. It uses sharp cutting tools, available in a variety of shapes and sizes, which are precisely controlled by a computer. CNC stands for Computer Numerical Control.

CNC Machining generally including of different processes of CNC Milling, CNC Turning, CNC Drilling, CNC Lathe,EDM, Wire-electrode Cutting, and Surface Treatment. Read More…..

Despite the advantage of 3D printing, CNC machining is still the most cost-effective manufacturing technique of on-demand manufacturing, especially for metal parts. Let’s check their cost break down details.

We will take a look into the cost details of CNC machining (including design, machinery, labor and raw material costs) and compare it to 3D printing prototype sample, CNC Machining is more accessible than you may think.

How much does cnc machining cost

Before you start a project with your custom design parts (aluminum, steel, brass, titanium, or plastic material) by cnc machining services with 3Q MACHINING, you need to know how much does cnc machining cost for your project based on the order quantity and product design drawing. 

We will take a look into the cost details of CNC machining aluminum (including product drawing design cost, cnc machinery cost, cnc technique engineer and operator labor cost, and different raw material costs), cnc machining is more accessible than you may think.

01. CNC Machining Machinery Costs

CNC machinery come in different variations. Depending on their machine architecture and capabilities the typical machine per hour differs.

Aluminum CNC machinery
  •  The typical cost rate of a 3-axis machining cnc milling machinery (including of the operator salary 10$) is 50$ per hour.
  • The 3-axis CNC Turning is usually priced lower at 40$ per hour because its machinery cost is lower and operation is simpler.
  • The average cost of 4 or 5 axis CNC machining from 75$ to 120$ or higher due to its high machinery cost and complex operation.
In general, we should choose a simpler CNC Machinery to manufacture our custom parts based on the material and part design, also quality requirements, with a rich experience engineer that can help you to define which CNC machining method we should choose to have best cost and good quality, also fast delivery.

02. CNC Raw Material Costs

Most of materials can be machined by CNC Machining with different custom designs, including of aluminum, titanium, steel, brass, plastic, or wood etc.

Aluminum Steel Raw Material Costs

The cost of your material is often given per 6″x6″x1″ sheet. The cost of some popular plastics per sheet are:

  • ABS costs $17 per block
  • POM (Delrin) costs $27 per block
  • Nylon 6 costs $30 per block

The cost of some popular metals for CNC machined parts are:

  • Aluminum 6061 costs $25 per block
  • Aluminum 7075 costs $80 per block
  • Stainless steel 304 costs $90 per block

CNC machining, being a subtractive manufacturing technology, has considerable waste as material is removed from the original block. 

It’s important to know that you will be charged for the use of a whole block. Where possible try to make as many parts of your design fit into one block as you can. This will mean you have fewer blocks to use overall and save you some cost in the order.

03. Labour Costs of CNC Machining

What Is a CNC Router

CNC Machining needs good experience engineer to build product drawing  (ProE, Solidworks, UG, or CAD etc.) with details including of dimensions, tolerance, raw material, surface treatment requirement etc., then have technique engineer to build machining program by MasterCam for operator to machine the custom parts with right CNC Machinery, the design cost is one-time charge set up cost, hence 1pcs order means same design cost with high volume order

Labor in CNC machining is primarily connected to start-up costs (CAM programming, process planning), but these are one time charge costs and are eliminated by higher production volumes.

CNC machining technology has not changed significantly during the past few years. Incremental improvements in machine design, tooling, consumables and CAM software lead to an optimization of the production cycles, improving quality and but not significantly affecting the cost of CNC machined parts.
