CNC Precision Machining of Large Parts

Large CNC machining is a subdivision of CNC machining designed to manufacture large diameter products. As a CNC machining process, it has many advantages such as high precision and accuracy. Large CNC machining is a type of CNC machining for the manufacture of large machine parts. Many industries require large CNC machining to make parts for their products, tools or machines.

How to machine large parts?

The multi-axis simultaneous machining service might be one of the biggest advantages of Kesu Group. As Kesu Group has invested in more than 100 advanced machines on the multi-axis simultaneous machining. We have a great advantages on the service of 3-axis machining, 4-axis machining, 3+2 machining, 5-axis machining and 6-axis machining. No matter the production of large complex parts or small precision parts, Kesu has a very big advantage.

Precision 3-Axis Machining 

Kesu’s Group has great advantage on the 3-Axis machining service. At present, Kesu Group boast 50 sets of 3-axis machines. We have rich experience on the 3-Axis machining. Since it can only be cut on three axes, the processing speed may also be slower than four-axis or five-axis CNC, because the workpiece may need to be manually re-positioned to obtain the desired shape.

Simultaneous 4-Axis Machining Service

4-axis machining or 4-axis milling is fantastic and cost-efficient when machining complex parts. As 4-axis machining can work as both CNC turning and CNC milling machine. 4-axis CNC service has great advantage on the spiral parts, polyhedral parts, spiral lines and cylindrical cams etc.  The 4-axis simultaneous machining service is one of the biggest advantages of Kesu Group.  At present, Kesu Group invested in 20 more 4-axis machines, which was 80 in the past. We have considerable experience on the 4-axis machining, especially in the impeller and the embossing roller of face mask machine.

Four-axis CNC machining will the best choice, if you need to drill holes on the side of a part or on the curved surface of a cylinder. It will speed up the machining process greatly and which will also remain high machining accuracy.

Four-axis Machining

Simultaneous 5-Axis Machining Service

Simultaneous 5-Axis Machining Service is the high-end CNC machining solution, which is suitable for the complex and difficult parts. Five-axis simultaneous machining is one of the biggest advantage of Kesu Hardware Group. At Kesu Hardware, we focus on 5-axis machining services for complex and high precision parts. Such as engine parts for automotive, impeller for rocket, areoplane, boat and cars etc.

An intellegent Look-ahead function for a continuous process

Advantages

High surface quality and transitions in combination with thermal compensation

Machines calibrated to half tolerance

Simultaneous 6-Axis Machining Service

6-Axis CNC Machining can reduce the production time greatly compared with 5-axis machining. The 6-axis simultaneous machining service is the promotion direction of Kesu Group. Currently, Kesu Group has 2 machines to provide 6-axis simultaneous machining services. Traditionally, 6-axis simultaneous machining means that all 6 axes could do simultaneous machining. This 6-axis simultaneous machining which we are talking about is based on the 5-axis simultaneous machining. It's Turn & Mill compound machining with the new ultra-compact patented turn-mill spindle compact MASTER. This machine could provide 6-sided complete machining by main spindle up to 700 Nm and optional counter spindle. In this way, the machine could provide 6-axis simultaneous machining.

Advantages of CNC machining

Compared with traditional machining, the advantages of CNC machining are welcomed by many industries in its manufacturing and manufacturing applications. The era of machine operation instead of manual operation has come. Thanks to the revolutionary innovation of CNC machines, CNC prototyping technology has been greatly improved. At the same time, its advantages are gradually revealed.

1. Security

The operator of the CNC machine is safely separated from all sharp parts by a special protective structure. He can still see through the glass what's happening on the machine tool, but he doesn't have to go anywhere near the mill or the spindle. The operator also does not have to touch the coolant. Depending on the material, some liquids may be harmful to human skin.

2. Save labor cost

Today, conventional machine tools require constant attention. This means that each worker can only work on one machine tool. When the CNC era came, the situation changed dramatically. Most parts take at least half an hour to process per install. But CNC machines are done by cutting the parts themselves. No need to touch anything. The tool moves automatically and the operator only needs to check for errors in the program or setup. Having said that, CNC operators find that they have a lot of free time. This time can be used for other machines. Thus, one operator, many machine tools. This means you save manpower.

3. Minimum setting error

Traditional machine tools rely on the operator's proficiency with measuring tools, and a good worker can ensure that parts are assembled with high precision. Many CNC systems use specialized coordinate measuring probes. It is usually mounted on the spindle as a tool, and a probe is used to touch the fixed part to determine its position. Then, determine the zero point of the coordinate system so that the setup error is minimized.

4. Complex surface processing is easier

For traditional machining, it is almost impossible to manufacture complex surfaces with high precision. It requires a lot of physical labor. The CAM system can automatically form the tool path of any surface. You don't have to make any effort at all. This is one of the biggest advantages of modern CNC machining technology.

5. Higher processing flexibility

Traditionally, milling machines machined grooves or flats, lathes machined cylinders and tapers, and drills machined holes. CNC machining can combine all of the above into one machine tool. Since the trajectory of the tool can be programmed, you can replicate any movement on any machine tool. So we have milling centers that can make cylindrical parts and lathes that can mill grooves. All of these allow for a reduced set of parts.
