How to solve the thermal deformation of metal laser cutting machine materials?

When we use the metal laser cutting machine, we may encounter various problems. At this time, only timely treatment can avoid more serious problems. If you don’t know how to deal with thermal deformation of the material, you can refer to the detailed method in the following article.

Among the thermal cutting processing methods used by metal laser cutting machines, the effect of thermal deformation on materials is currently a major problem that affects the processing quality of metal laser cutting machines. First of all, we can give a point of view that is to use metal laser cutting The thermal cutting method of the machine cannot completely avoid the thermal deformation of the material.

Judging from the current industry application technology, whether it is water jet treatment or high-speed cutting technology, it is used to minimize the impact of thermal deformation rather than avoiding it. Therefore, this is also for many companies that are planning to purchase metal laser cutting machine equipment. Some reminders from the purchaser that manufacturers who boast that equipment can completely avoid the effects of thermal deformation need to be cautious.

Since it is impossible to completely avoid the thermal deformation of the metal laser cutting machine, what we can do is to make breakthroughs in equipment hardware design and related patented technology, and more importantly, we need equipment operators to standardize the operation process .

The metal laser cutting machine itself is used as a thermal cutting processing equipment, and during frequent processing, it will also cause structural deformation due to temperature changes. Although as a production and processing equipment, the metal laser cutting machine will adopt a series of processes in the manufacturing process to minimize the impact of thermal deformation, but as a user, in the usual use process, you should still understand this knowledge and standardize the operation. Procedures to reduce possible thermal deformation effects.

1. Reduce the heat generated by the metal laser cutting machine

The main heat source that produces thermal deformation when the internal heat of the metal laser cutting machine machine tool is heated, the heat source should be separated from the host as much as possible.

2. Improve the mechanism of metal laser cutting machine

Under the same heating conditions, the machine tool mechanism of the metal laser cutting machine also has a great influence on the thermal deformation. For example, the single-column mechanism used in CNC machine tools in the past may be replaced by a double-column mechanism. Due to the left-right symmetry, the main axis of the double-column mechanism after heating produces little deformation in other directions except for the vertical translation, and the vertical axis movement can be easily compensated by a coordinate correction.

3. Control the temperature rise of metal laser cutting machine

After taking a series of measures to reduce the heat source, the thermal deformation will be improved. However, it is usually very difficult or even impossible to completely eliminate the internal and external heat sources of the metal laser cutting machine. Therefore, the temperature rise must be controlled through good heat dissipation and cooling to reduce the influence of the heat source. The most effective method is to force cooling in the heating part of the machine tool. You can also heat the low temperature part of the machine tool to make the temperature of each point of the machine tool uniform, which can reduce the warping deformation caused by the temperature difference.

The thermal deformation of the shaft occurs in the vertical direction of the cutting tool. This can minimize the influence of the thermal deformation of the spindle on the machining diameter. In terms of 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. At the same time, the temperature rise of the headstock box should be consistent before and after to avoid tilting of the main shaft after deformation.

The ball screw in the metal laser cutting machine tool often works under the conditions of high expected load, high speed and poor heat dissipation, so the screw is prone to heat. The consequences of the thermal production of the ball screw are serious, especially in the open loop system, it will make the feed system lose the positioning accuracy. At present, some machine tools use a pre-tensioning method to reduce the thermal deformation of the lead screw. For the thermal deformation that cannot be eliminated after taking the above measures, the numerical control system can send out compensation pulses to make corrections based on the measurement results.

According to the above method, the thermal deformation of the material in the operation of the metal laser cutting machine can be handled well, and other measures can be found later.
