High Quality Ventilation and Ductwork Supplies From VENTECH

When laser cutting sheet metal parts, it will generate a lot of heat, and the heat will not spread in time, resulting in the phenomenon of edge burning. In the small hole processing of the metal laser cutting machine, the outside of the hole can be cooled, but the inside of the single hole small hole is too concentrated due to the small heat dissipation space, resulting in overfire, slagging, etc. In addition, in the cutting of thick plates, the accumulation of molten metal and heat accumulation on the surface of the material will cause turbulence in the auxiliary airflow and overheat input, resulting in excessive combustion and edge combustion.

So, how to solve the problem of edge burning and slag hanging?
Solution for excessive burning of small holes in laser cutting carbon steel: In carbon steel cutting with oxygen as an auxiliary gas, the key to solving the problem is how to suppress the generation of oxidation reaction heat. Auxiliary oxygen, auxiliary air or nitrogen cutting methods can be used. This method can be used to process small holes with an upper limit of 1/6 thickness.
Pulse cutting conditions with low frequency and high peak output power can reduce heat output and optimize cutting conditions. Setting single pulse laser beam, high energy peak output and low frequency conditions can reduce the accumulation and heat output of molten metal on the surface of the material.
The solution to this problem is to increase the pressure of the auxiliary gas and set the conditions to high peak output and low frequency pulses. When air is used as an auxiliary gas, such as using nitrogen, excessive combustion will not occur, but slag can easily appear at the bottom. It is necessary to set the conditions to high auxiliary pressure, high peak output and low frequency pulse conditions.

Economic gantry CNC cutting machine is also called light gantry CNC cutting machine. Due to the digital control function of its heavy gantry CNC cutting machine and its advantages in lightness and economy, the economic gantry CNC cutting machine can completely replace semi-automatic cutting machines, a large number of manual cutting machines and a small part of traditional heavy CNC cutting machines. It has a wide range of applications, especially suitable for most small and medium-sized micro-processing enterprises, and has a good market prospect.

In fact, whether it is a flame, plasma or a light-weight cutting machine, it is a thermal cutting, and it is also a non-contact cutting. When cutting, the torch keeps a certain distance from the steel plate, and uses the heat of flame, plasma arc or exciting light beam to melt the metal and create gaps. Due to the non-contact type, the CNC cutting machine does not generate any resistance torque during the cutting process, so the design of the machine tool can be light and does not need to be cold treated, which requires the machine tool to have a large dead weight, so as to ensure that the cutting force will not cause the machine tool Movement or shaking of itself. , And ensure normal processing.
The traditional heavy gantry CNC cutting machine, due to the design concept of cold working machine, especially when the CNC cutting machine was born decades ago, the electronic and numerical control technology was not developed, the control system and the height adjustment device It is very heavy, so large and heavy gantry CNC cutting machines are very popular in the processing field. Especially in large enterprises and some regional metal cutting machine cutting processing service centers, the traditional heavy-duty cutting machine has become the default common name mode. The majority of users also think that the gantry CNC cutting machine should be so big and so heavy.

The gantry CNC cutting machine itself does not require much weight, as long as the material table is stable enough to bear the weight of the steel plate. Gantry CNC cutting machine can be light and miniaturized. With the development of electronic technology and the miniaturization of traditional control systems, lightweight gantry CNC cutting machines will continue to appear.
