CNC Milling

CNC milling2

CNC milling is a computer-controlled process that involves using cutting tools to remove part of a workpiece. The processing of a milling machine is that the tool rotates and the workpiece does not rotate. The material being machined is flat. CNC Milling can process flat surfaces, grooves, spiral surfaces of toothed parts, and various curved surfaces.

DMTC(Shenzhen DMTC Intelligent Technology CO., LTD) can provide suitable materials for CNC Milling: aluminum, nylon, copper, steel, titanium alloy, POS, PEEK, ABS, PVC, Nylon, brass, etc.

The applications of CNC Milling: auto industry, electrical industry, medical industry, consumer products, etc

We(Shenzhen DMTC Intelligent Technology CO., LTD) own advanced multi-axis CNC milling machines, that can help you finish high-quality parts with fast lead times.

The definition of CNC milling work:

CNC milling is a computer-controlled process that uses cutting tools to remove extra parts of a workpiece. CNC milling machine consists of a workbench and cutting tools attached to a spindle. The workpiece is placed on the machine’s table while the cutting tool rotates to shape the workpiece, this machining process is CNC milling work.

3 steps of the CNC milling process:

Prepare designs: Finish the 2D/3D drawing of CNC milling partsby CAD or CAM, the drawing should include some important information such as dimension, tolerance, surface finishing, and keynotes of the parts. Then convert CAD/CAM designs into CNC programming languages, the CNC milling machine can machine the parts according to the drawing.

Set up the CNC milling machine: The CNC milling machine can cut the materials automatically, but something of the process still need the help by a machine operator. For example, the operator must secure the workpiece to the workbench and adjust the spindle’s cutting tools.

Prepare alternative cutting tools: CNC milling uses a rotating tool that cuts off chips as it contacts the workpiece. Using the larger tools for the first few passes to carve the material get a shape, and change other tools create more accurate machined parts.

Various CNC milling processes:

  1. Face milling

The face milling process uses a horizontal milling machine. The tool has an axis of rotation parallel to the table. It uses different tools of different shapes and orientations depending on the shape and size of the last parts.

  1. Side face milling

This type of milling process uses a cutting tool with teeth on the sides and ends. The side teeth do the main cutting work and the other teeth on the tip improve to the surface finish.

  1. Different angle to milling

It is one of the best milling processes for creating recesses, chamfers, slots, and other parts with complex features. The axis of the tool is usually perpendicular or in line with the cutting surface.

  1. Forming milling

Form milling refers to the milling process involving irregular surfaces, contours, and grooves, such as parts with partially curved or fully curved surfaces. This CNC milling process uses special tools to create CNC milling parts with more complex contours

  1. Other CNC milling processes:

In addition to the milling processes mentioned above, CNC milling machines can also perform other types of specialized milling processes, such as copy milling process and linkage milling.

The advantages of CNC milling work:

  1. High precision and accuracy

The characteristics of CNC milling work minimize the possibility of error, ensuring high accuracy and precision.

  1. High efficiency and repeatability

CNC milling machines can offer high throughput because of the automation. Advanced milling machines can produce parts faster with higher quality and finish.

  1. Broadly material compatibility

CNC milling works on a variety of materials, including metal, plastic, glass, and wood. It increases its versatility, making it ideal for a variety of applications.

  1. Reduce workers and save costs

The high automation and throughput of CNC milling machines significantly reduce the labor used in the process.

  1. more cost-effective

CNC milling machines can efficiently produce complex products faster and more accurately. It reduces the production time and saves the cost.

Common materials used in CNC milling work

CNC milling works on a variety of materials. The choice of material will depend on the requirements and specifications of the application. The most common materials include metal and plastic material.

Metal material: Aluminum, Stainless steel, Steel, Brass, Copper, Titanium, etc.

Plastic material: POS, ABS, Nylon, Teflon, PC, PVC, Acrylic, PEEK, etc.

The applications of the CNC milling process:

  1. Aerospace industry: The milling process is suitable for manufacturing aerospace parts from aluminum and titanium materials because these materials are durable and lightweight.
  2. Auto industry: Parts machined for the automotive industry must be efficient and precise. Therefore, the CNC milling process is suitable for the production of interior panels, drives, cylinder heads, gearboxes, exhaust components, suspension components, etc.
  3. Medical industry: Medical and surgical tools always with unique designs that require high precision. This makes the CNC milling process one of the best methods for creating such medical CNC milling parts.
  4. Consumer products: The CNC milling process produces common parts. Such as nuts and bolts, gears and shafts, flanges, and more. The process is also suitable for short-run and large-scale production.
