How To Reduce Thermal Change Of Laser Cutting Machine?

Now, many users experience thermal distortion during the use of laser cutting machines. If you can't solve it well, it may affect the normal operation, so everyone hopes that there can be some methods to reduce its thermal deformation.

Customers who often deal with cutting machines often encounter the problem of thermal deformation of laser cutting machines, CNC flame or plasma cutting machines, regardless of CNC flame cutting or plasma cutting, because the width of the cutting edge is affected by many factors such as cutting nozzles, so whether How high is the accuracy of the equipment itself, and the accuracy of the parts cut by it is generally about ±0.5mm, which is several orders of magnitude higher than the equipment itself.

So how to solve it? First of all, this situation is inevitable. Thermal cutting definitely dissipates heat. It can only be said to reduce the occurrence of this situation. Here are three solutions:

1. After controlling the temperature rise and taking a series of measures to reduce the heat source, the thermal deformation will be improved. A more effective method is to force cooling in the heating part of the CNC plasma cutting machine, or heating in the low temperature part of the machine, so that the temperature of each point of the machine is uniform, which can reduce the warpage caused by the temperature difference. 

2. The heat source of thermal deformation caused by heat inside the machine tool should be separated from the main body. Thermal deformation of the shaft occurs in the vertical direction of the cutting tool. For example, the single-column mechanism used in CNC machine tools in the past can be replaced by a double-column mechanism.

This knowledge should be learned more to standardize the operation and reduce the effects of possible thermal deformation. As thermal cutting processing equipment, CNC flame cutting machine may cause structural deformation due to temperature changes during frequent use and processing.

3. Improve the machine tool mechanism. Under the same fever condition, the machine tool mechanism also has a great influence on thermal deformation. In this structure, the distance between the center of the main shaft and the main shaft to the ground should be reduced as much as possible to reduce the total amount of thermal deformation. This minimizes the effect of thermal deformation of the spindle on the machining diameter.
