Why Choose JTR for CNC Milling?

Lead Time – JTR Machine uses the latest CNC machines to produce high-precision and fast-milling parts, the fastest time is within one day, to offer our customers a very short lead time.

Quality Guaranteed – We can provide all types of customized CNC milling parts to meet your project needs. Our experienced engineers will design the milling process and select the appropriate tool based on your drawings, then do the milling quickly while obtaining a good processing surface. By maintaining our strict tolerances, we ensure you the best quality.

Low cost – With our more than 70 CNC machining centers and a super cooperative professional work team, we can make the production cost at the lowest level by shortening the production time, labor cost. We at the same time can offer you some free services such parts assembling which will be based on your needs.

More material and surface finishing options – In addition to time-saving, another advantage of CNC milling is that various types and specifications of plastics and metal blocks can be used for milling. CNC milled parts can also be subjected to different types of surface treatment, such as painting, anodizing, and chrome plating. The perfect combination of functionality and omnipotence.

Ability to handle complex parts – Since the cutting tool of the milling machine can approach the workpiece from multiple different angles, it is possible to create CNC parts with complex shapes. With more axes, more complex parts can be created. If your CNC project requires irregular shapes, milling is usually the best choice.

Overview of CNC Milling

What is CNC Milling?

CNC Milling is a type of CNC machining process that uses rotary cutting tools, that move along multiple axes, to remove material from a block. Our CNC milling process uses 3-axis, 4-axis and 5-axis indexed milling to rapidly cut a choice of more than 30 engineering-grade thermoplastics and metals into complex shapes and precision components.

How Does CNC Milling Work?

Like other machining processes, CNC milling starts with designers using CAD (computer-aided design) software to create digital parts. Then the file is converted into “G code”, thus can be recognized by the CNC milling machine.

The CNC milling machine has a “worktable” and workpiece fixing devices to fix a large piece of material (called a “workpiece”) in place. The workbench may or may not move, depending on how the machine is set up.

In the process of CNC milling, a rapidly rotating cutting tool comes into contact with the workpiece, thereby cutting away the material. The tool moves according to the G code instruction to cut in the correct position until the part is completed. Some CNC milling machines use moving tables to create more cutting angles.

CNC Milling Process Flow Chart

CNC rolling mills can cut through hard metals. This makes them more versatile than CNC milling machines, which are similar to 3-axis milling machines but have a weaker ability to penetrate hard materials.
A CNC milling machine is different from a CNC lathe or turning center. In a CNC lathe or turning center, the workpiece rotates instead of the cutting tool.

Different Types of CNC Milling

CNC milling machines are usually defined by the number of their axes. More axes mean they can move their tools and/or workpieces in more ways, thus providing greater cutting flexibility and being able to produce more complex parts in less time.

3-axis: Standard CNC milling cutters have a 3 axis, allowing the spindle (and connected cutting tool) to travel along the X, Y, and Z axes. If the cutting tool cannot reach the part area, the part must be removed and rotated manually.

4-axis: Some CNC milling machines add extra degrees of movement by rotating on a vertical axis. This provides greater flexibility and can create more complex parts.

5-axis: The most advanced type of CNC milling machine widely used is a 5-axis milling machine, which adds two additional degrees of motion by increasing the rotation of the table and spindle. Parts usually do not need multiple settings, because the rolling mill can move them to different positions.

CNC Milling Tools

CNC milling machines can be equipped with different knives/tools to achieve different types of cutting. These tools include end mills, face milling cutters, slab milling cutters, fly cutters, ball cutters, hollow cutters, roughing end mills, etc.
