How to effectively control the cost of using laser cutting machine?1

In many cases, if you don’t control the cost of using the laser cutting machine, it will incur more costs, so this is an important reason why users hope to have some methods to control its cost. Let’s do it together. Take a look at how to control the cost incurred in the operation of the laser cutting machine.

Nearly 80% of the cost of using laser cutting machines comes from the consumption of gas. As the main energy supply for laser cutting machines, CNC laser cutting machines and manual gas cutting equipment, you will be familiar with and understand the gas application principles of laser cutting machines. Help reduce the cost of gas usage. In this regard, the Ministry of Science and Technology has used many debugging experiences of CNC laser cutting machine equipment, and summarized the relevant knowledge and experience as follows:

First of all, you must be able to adjust the flame skillfully. The first problem is to ensure the normal cutting of the billet. If the automatic cutting cannot be completed successfully, you must manually use the hand torch to re-cut, which causes waste, and manual cutting is not possible. Ensure that the cutting quality is intact.

By solving some abnormal phenomena and cutting effects of CNC laser cutting machine processing, such as 'constant open flameIn order to avoid waste; in addition, it is necessary to actively promote and test new technologies and new products, highlighting the emergence of new products in the cutting nozzle, the 'flame' is more perfect, the cutting effect is improved, the cutting seam is small, and the gas consumption is relatively low.

With the increase in the amount of steel used in related industries, flame cutting has become an indispensable link in the production and processing of more and more companies. For flame cutting, in addition to ensuring the necessary cutting accuracy, How to effectively reduce production costs and control gas consumption is becoming a concern of most companies. In terms of the relevant experience in the use of CNC laser cutting machine equipment we talked about above, only some of the problems involved in the details of the operation. From a big point of view, companies want to effectively reduce the cost of equipment use, but also need to learn from the flame Start with the principle of gas cutting.

Flame cutting, also called gas cutting, is a process of burning with oxygen/gas flame. In the first step, the temperature of the steel plate must rise to the ignition point. Then, the oxygen stream oxidizes the metal in the long and narrow area, and the slag generated during combustion is blown away by the cutting oxygen stream to form a slit.

Oxygen gas cutting can be used for carbon steel and low alloy steel, and the thickness can reach several decimeters. The cutting quality depends on the surface condition of the material, the cutting speed and the thickness of the material.

The typical thickness of flame cutting is recommended to be in the range of 6-150MM, which is also the thickness of the cutting machine that can be achieved by the current CNC laser cutting machine; but flame cutting is the cutting method with the largest cutting thickness among many cutting methods. Generally, if When the cutting thickness is higher than the typical thickness, the gas path of the cutting machine, the cutting gun, the amount of oxygen and gas must be changed, and the steel cannot be cut if the power fails to meet the requirements.

The above is some experience in the application of automatic laser cutting machine. However, to use the automatic laser cutting machine well, you first need to master the flame of the cutting torch. The key to adjusting the flame is the gas source. Most of the oxygen on site is the pipeline oxygen. The purity and pressure of the oxygen can generally meet the requirements for use, but there is more gas. For the bottled gas supply, a 30 kg bottle of gas, in the scale of 5 machines and 5 streams, the use time is about 2 hours. In this way, the gas source must be replaced in the middle, which will cause large fluctuations in gas pressure, which directly affects the gas flow. , Resulting in abnormal cutting.

In addition, to ensure that the current equipment is in good condition, usually based on the operating regulations, regularly check for leaks in pipelines and joints, lubricate the bearings, pin holes, etc., and clean the cutting nozzles and cooling water pipes. Only by completing some routine procedural work can we ensure normal operation, and then we can improve and improve the effect.

In view of the specific equipment, large-scale flame gas cutting, such as a stripe CNC laser cutting machine, is generally equipped with more than ten sets of flame cutting torches. Generally speaking, straight line laser cutting machines (multi-head laser cutting machines) are divided into the following three types: They are all used for steel plate cutting.

1. The simplest straight strip laser cutting machine, which can evenly divide the steel plate into strips. It is simple and practical, low in price, and has a good sales volume.

2. In addition to the simple steel straight strip cutting function, a flame cutting gun is added horizontally, so it can cut straight strips and cut straight strips. The function is stronger, but in most cases, users In order to save costs, manual lateral cutting is also often used. This kind of cost is more expensive than the first one.

3. CNC straight strip laser cutting machine, this is the most powerful and advanced at present, so the price is also the most expensive. In addition to the main functions of 1 and 2 types, there are also powerful The CNC special-shaped cutting function can be equipped with CNC flame and CNC plasma cutting, making it the most versatile CNC flame plasma straight cutting machine.

In addition to sharing how to control the cost of the laser cutting machine, the above content also introduces some of its use principles.
