What kind of machine tool can meet high-speed cutting?

High-speed cutting refers to cutting processing at a speed much higher than the conventional cutting speed. At present, there is no uniform definition of the speed range of high-speed cutting in various countries. Usually, cutting that is 5 to 10 times higher than the conventional cutting speed is called high-speed cutting. One of the main goals of high-speed cutting is to reduce production costs through high productivity. It is mainly used in finishing processes, and is often used to process hardened die steel. Another goal is to improve overall competitiveness by shortening production time and delivery time.

High-speed cutting technology is a very large and complex system engineering. What are its advantages over traditional machining? For machine tools, how can they meet high-speed cutting?

After the concept of high-speed machining was put forward, after long-term exploration, research and development, it has been widely used in industrial production in the near future. The high-speed cutting system is mainly composed of high-speed cutting cnc machining tools, high-performance tool clamping systems, high-speed cutting tools, and high-speed cutting cam system software. The reason why high-speed cutting is more and more widely used in the industry is because it has significant advantages over traditional machining

What kind of machine tool can meet high-speed cutting?

1. Short processing time and high efficiency.
2. The cutting condition of the tool is good, the cutting force is small, and the force on the spindle bearing, tool and workpiece is small.
3. The tool and workpiece are less affected by heat.
4. Good surface quality of the workpiece.
5. The high-speed cutting tool has good thermal hardness.
6. It can process high hardness materials and hardened steel with hardness up to hrc40-62.
For what kind of machine tool can meet high-speed cutting, it can be roughly divided into the following requirements:

1. The mechanism design is suitable for high-speed operation

The high-speed machine tool first requires its mechanism to have high rigidity, to be able to absorb high-frequency vibration and high inertia G value to ensure high-speed cutting precision and stability.

2. Excellent CNC control system

The CNC numerical control system is the unit that issues position instructions, which requires that the instructions can be transmitted accurately and quickly. After processing, the position instruction is issued to each coordinate axis. The servo system must quickly drive the tool or the table to move accurately according to the instruction. It requires the ability to quickly process the program segments, to be able to control the CNC machining error to a minimum, and so on. In the field of high-speed machining applications, Siemens 840D and Fanuc18iMB are the most representative.

3. Tool holders and tools suitable for high-speed operation

High-speed cutting tools, especially high-speed rotating tools, are required to have better quality and performance in terms of ensuring machining accuracy and operating safety.

4. Professional CAD/CAM software

Professional CAD/CAM software requires a precise path calculation method, which can not only accurately meet the accuracy requirements of 3DProfile, but also reduce the discharge process, and even achieve the surface quality requirements without polishing. It must be able to generate a good cutting path and stabilize the cutting volume, which not only improves

machining efficiency, but also prolongs tool life and saves tool costs.
