How fast is the appropriate speed for CNC leather cutting machine?

In the era of Industry 4.0, people pursue production efficiency and require faster and faster cutting speeds, but is this really good?

Effects of too fast cutting speed

① Accelerate the aging of parts and shorten the service life of the machine

The cutting principle of the vibrating knife leather cutting machine is to use the high-frequency vibration of the blade tens of thousands of times per minute to cut. If the cutting speed is too fast, the cutter head and connecting beam will be loaded. If things go on like this, it is easy to accelerate the cutter head and beam. Wear can severely shorten the service life of your machine. Replacing the cutter head is not expensive, but the wear and tear of the cutting machine beam is irreversible, and the replacement cost can reach hundreds of thousands.

②Leather waste

If the cutting speed is too fast and the time the blade stays on the leather material is too short, continuous cuts may occur or one side may be cut off but the other side may not be cut off. Moreover, the cut pieces have a large error and cannot be stitched later. It will also cause a waste of leather materials.

③Reduce production efficiency

The fastest cutting speed does not guarantee maximum productivity. The efficiency of production links such as laying, scanning and typesetting, cutting, and receiving should also be considered. If all links cannot be connected, the faster the cutting speed, the higher the error rate. Especially in the online production mode, only when the connection and balance between various links reaches the highest level can our production efficiency be maximized, which is far more important than simply increasing the cutting speed.

How to judge whether the cutting speed is appropriate

After the leather cutting machine is debugged by professionals, the cutting surface of the cut piece is smooth and flat, and can be directly sewn on the back section. The cutting speed at this time is ideal.

If the online typesetting mode is adopted, whether the connection between scanning, typesetting, cutting, and receiving is efficient will have a great impact on production efficiency. If you blindly pursue faster cutting speed, other production links will not be able to keep up. In fact, the machine cannot operate at full capacity, which is also a waste of man-hours to a certain extent.
