Our CNC Milling Services

We provide CNC milling services for any custom CNC part, whether complex or straightforward, plastic or metal. With our precision 3-axis, 4-axis and 5-axis CNC milling centres, combined with other advanced capabilities and our experienced team, we can provide high-quality CNC parts with fast delivery. We guarantee that your CNC milling project will be handled smoothly by our in-house CNC department and supplier network, meaning your team can focus on getting your product to market. If you are looking for a reliable CNC milling company, Keyanng will not let you down!

CNC milling is the most common CNC machining process. After the workpiece is properly positioned, material is removed from the workpiece by rotating and moving the tool. The movement of the tool is controlled by computer instructions with extreme precision and repeatability.
The milling cutter can be placed horizontally or vertically, but since CNC machines have 3-axis, 4-axis, and 5-axis differences, this video shows a 4-axis CNC milling machine.

Materials for CNC Milling Parts

Surface Finishes for CNC Milling Parts

Typical CNC Milling Parts That We Offer

CNC milling is a very flexible way to create prototypes or manufacture large quantities of end-use parts. And there’s a wide range of milling materials to choose from, so it’s suitable for most projects. Our CNC experts know how to cut parts quickly to keep costs down and mill custom-designed parts with complex geometries and tight tolerances in different materials. We have delivered tens of thousands of high-quality CNC parts to customers worldwide.

Machine Components

This is a rotary cutting machine for N95 mask machine. Its function on the machine is to press the multi-layer fabric bonding and shape the mask.

This is our most typical processing project, not just the mask machine, we have manufactured machine parts for 1500+ customers so far.

Mold Components

CNC milling plays an important role in mold making. Cavities, mold bases, slides, tappets and other mold components can be milled. Our injection molds are made with a CNC milling process, which allows the mold to maintain consistent precision and surface finish.

Automotive Prototype

Interior panels, molds, drivetrains, pistons, camshafts, turbochargers, aluminum wheels, starter motors, cylinder heads, driveshafts, transmissions, custom parts, and prototype applications—all of which require CNC milling

Medical Parts

Accessories for handheld devices, anatomical models, teaching aids, electronics, ultrasound equipment, physiotherapy equipment, and we are familiar with fracture plates and other parts that can be used in surgery.

Food Industry Parts

Food processing machines and components for cooking, packaging, preparing, storing and handling food.

Electrical Accessories

Electronic hardware, enclosures, metal slats, panels, thin wires, engraved parts and other CNC machined electronic components

Overview: What is CNC milling?

CNC milling is the most common CNC machining process. The material is removed from the workpiece by rotating and moving the tool. The device’s movement is controlled by computer instructions with extreme precision and repeatability.
Milling is different from CNC turning. CNC turning is another standard CNC service. The workpiece rotates, the tool moves in a straight line or a curve, and the tooltip moves relative to the workpiece while removing a certain amount of workpiece material. Get final custom CNC turned parts with desired specifications. Unlike milling, CNC turning is often used to create circular or tubular shapes.
CNC milling can be used for complex contour shapes， Parts that require high precision.

1. First, carry out process analysis according to the part processing drawing, and determine the processing plan, process parameters, and displacement data.
 2. Use the specified program code and format rules to write the part processing program list, or use the automatic programming software for CAD/CAM work to generate the part processing program file directly.  
3. The content of the processing program is entirely recorded on the information medium (such as punched tape or magnetic tape) in the form of code.
4. The code on the information medium is converted into an electrical signal by the reader and sent to the numerical control device. Programs written by hand can be input through the operation panel of the CNC machine; programs generated by the programming software are directly transmitted to the CNC unit (MCU) of the CNC machine through the serial communication interface of the computer.  
5. After the numerical control device performs a series of processing on the received signals, the processing results are sent to the servo system to execute commands in the form of pulse signals.  
6. After the servo system receives the executed information command, it immediately drives the milling machine feed mechanism to move in strict accordance with the requirements of the order so that the milling machine can automatically complete the processing of the corresponding parts.

Its number of axes usually defines a CNC milling machine. More axes mean they can move their tools and workpieces in more ways, providing greater cutting flexibility and the ability to manufacture more complex parts in less time.

3 Axis: Standard CNC mills have three axes that allow the spindle (and attached tool) to move along the X, Y, and Z axes. If the cutting tool cannot reach an area of the part, the part must be removed and rotated manually.

4-axis: Some CNC mills add an extra degree of motion by rotating vertically. This allows for greater flexibility and the ability to create more complex parts.

5-axis: The most advanced type of CNC milling machine in widespread use is the 5-axis milling machine, which incorporates two additional angles of motion, usually by increasing the rotation of the table and spindle. Parts often don’t need multiple setups because the milling machine can manipulate them to different positions.
