High Quality Cnc Laser Cutting Machine

Three points of labor, seven points of equipment, this is the essence of stainless steel sheet cutting. If a good workpiece is not processed by a metal laser cutting machine in the early stage, it will be difficult to remedy it in the later stage, and it will not be able to achieve the seven-point equipment mentioned at the beginning. The processing of stainless steel sheet cutting has to go through multiple steps of processing, among which cutting or cutting is an important step, so the metal laser cutting machine has a very important role.


The quality of the cutting process of stainless steel sheet also affects the development of several subsequent processes, so how to cut stainless steel quickly, let's take a look at it together.


Important equipment for stainless steel sheet cutting-metal laser cutting machine


Many people's understanding of metal laser cutting machines only stops at the appearance and application, and they rarely associate metal laser cutting machines with cutting materials. In the past, metal processing relied on manual and physical methods. Gradually everyone found that these methods were too low compared to these metal laser cutting machines. The metal laser cutting machine gradually replaced these traditional methods and became the only equipment for stainless steel sheet cutting.


The advantages of stainless steel sheet metal laser cutting machine


Metal laser cutting machine is not an important equipment for cutting stainless steel sheet for no reason, but with 5 major advantages.


1. Fast cutting speed and high efficiency.


2. Stable and durable, flexible and intelligent.


3. Non-contact machining effectively protects the workpiece and will not damage the surface of the workpiece


4. High processing accuracy, capable of fine cutting thin plate materials


5. Save money, time and effort


These 5 advantages are the important reasons why metal laser cutting machines are used in stainless steel sheet cutting, so how to choose a good metal laser cutting machine?


1. Produced by a brand manufacturer, with a certificate, factory certificate, etc.


2. Determine the processing material and determine the laser power of the processing equipment


3. The core components are well-known, guaranteed, and detailed instructions.


4. Good reputation, praises used by peers are constantly waiting


Contrasting these conditions, you can find the right one by searching for relevant metal laser cutting machine equipment on the Internet.

Maintaining punching machine manufacturer is not as easy as it may seem. You have to do plenty of important tasks. So cruel is the truth unless you've got a to help you.

During the operation of the laser cutting machine, if the cutting torch fails, it is a serious problem, no matter what, everyone must not ignore it. It must be repaired according to the correct method, so how to repair the torch of the laser cutting machine? The following content is a specific introduction:



During the use of the laser cutting machine, nearly half of the faults are concentrated in the cutting torch. Among them, the cutting torch is damaged due to cutting slag, the cutting quality is affected by the collision of the cutting torch, and the cutting The torch height adjustment failure is difficult to control and so on. This article will mainly explain the maintenance and arrangement of the torch parts of the laser cutting machine:



1. Torque gun head



The parts of the laser cutting machine The cutting head is a key part of the head box, which is composed of electrodes, distributors, nozzles, pressure caps, porcelain sleeves, etc. These are all vulnerable parts and should be replaced in time if there is an abnormality in normal use. The direct current output by the host power supply is sent to the electrode of the torch by the main cable. At the same time, the compressed gas and coolant output by the controller are input into the inner cavity of the torch, and enter the gap between the electrode and the nozzle through the distributor, according to the designed state and The flow jets out of the nozzle to provide the air flow conditions for the formation of plasma flow. Tip cooling is very important,
Keep the air pipe and water pipe unobstructed during use, and no foreign objects should be blocked. Often the torch tip is not cooled well and causes the machine to stop. At this time, the nozzle should be removed and the pipeline should be checked carefully. The inside of the nozzle should be clean and shiny, without electrode deposits, otherwise it must be polished.



2. Spark gap



The spark gap is a key component of the oscillating circuit, which is composed of a discharge electrode, a connecting bolt, and a base. The discharge electrode is a high-temperature resistant metal rod, and the electrode gap is between 0.8 and 1.2 r a m. happen
During high frequency oscillation, the high voltage will break down the air between the spark gap electrodes, forming an arc discharge. Under normal circumstances, the spark gap should be checked frequently to keep its surface level. The possible fault is that the spark gap cannot automatically break the arc,
The reason is generally that the control circuit board components are out of adjustment, and it may also be that the discharge electrode gap is inappropriate.
At this time, adjust the gap and use corundum emery cloth to polish the electrode to eliminate the round tip of the electrode.



3. Silicon rectifier or chopper



The three-phase full-filtering rectifier bridge rectifier circuit is mainly composed of SCR components, which is an open-loop control system, and the trigger conduction angle is set by the potentiometer. The parallel filter capacitor of the thyristor carries a high voltage
, When repairing, be sure to wait for 5 min after the power outage, and wait for the charge stored in the capacitor to discharge before starting the repair operation.



The above is an introduction to the correct maintenance of the torch of the laser cutting machine. I wonder if there is still something unclear after reading it?


are an important part of the society and they come in handy in any place where there are assembly machine manufacturers in need of powder coating machine price.
