Laser cutting machine has become an indispensable tool for metal sheet processing enterprises. However, when using laser cutting machine for processing, we encounter some problems, like the large gap of steel plate and the reduced accuracy of the processed components.
A lot of heat will be generated, which may deform the surface of the thin plate and the processed workpiece.
The focus of the laser cutting machine and the surface of the processed object change, causing the large cutting gap or inaccurate processing.
An error will occur due to the incorrect position of the worktable. If the laser cutting machine is not installed firmly and the parts are worn for a long time, the worktable surface will be uneven. This imbalance will also cause problems between the thin steel plate and the laser focus, resulting in excessive cutting gaps or reduced processing accuracy.
One of the biggest advantages of laser cutting machine is to cut a wide range of materials.
Laser cutting machine can cut all types of metals, ranging from mild steel to stainless and non-ferrous metals. More reflective metals like aluminum are more difficult to cut. The thickness of the metal can be up to 30mm. The maximum thickness depends on the laser cutting machine.
Different types of wood are suitable for cutting like plywood and MDF. However, be aware of oils or resin to avoid fire.
Paper and cardboard are also suitable for laser cutting machine, where the popular wedding invitations are made.
Plastics also leave a great finish when using laser cutting machine that the edges are melted in a polished way.
POM is a highly utilized plastic in the engineering sector, finding usage in gears, guiding and sliding elements, medical instruments, and food packaging. It can also be cut by laser cutting machine.
Cutting glass is a seemingly impossible task because of its fragile and reflective properties. However, laser cutting machine can engrave glass.
Replace the circulating water once a week. Make sure that the laser tube is filled with circulating water before the laser cutting machine works. It is recommended to use pure water and keep the water temperature below 35°C.
Long-term use of the fan will accumulate a lot of solid dust, making the fan generate a lot of noise and not conducive to exhaust and deodorization. Disassemble the air inlet and outlet pipes on the fan. Remove the dust inside. Turn the fan upside down and pull the inner blades until they are clean.
It is recommended to clean lens before laser cutting machine works every day. There are 3 mirrors and 1 focusing mirror on the machine. The lens are easily stained with dust or other contaminants, which can cause laser loss or damage to the lens. Just rotate to wipe from the center to the edge with the lens wiping paper.
After the motion system has been working for a period of time, the screws and couplings at the motion connection will loosen, which will affect the smoothness of the mechanical motion. Observe whether there are abnormal noises or phenomena in the transmission components.
It is recommended to check whether the optical path is normal before each work.

An efficient press brake is fundamental to avoiding damages and detecting failures. Keeping press brake clean and tidy is simple but important. It should be done the daily, weekly, monthly, and yearly.
Why does press brake leak oil?
What should you do for oil of press brake?
What is the role of oil of press brake?
The sealing ring is not suitable for the conditions of using press brake. The O-shaped rubber seals often used in press brake must be selected according to the operating conditions and working conditions. Under oil lubrication conditions, the hardness of the oil-resistant rubber O-ring seal can be low hardness when the oil pressure is less than 2.9MPa. When the oil pressure is 2.9 to 4.9MPa, medium hardness should be selected. When the oil pressure is 4.9 to 7.8MPa, select high hardness.
There is no design seal or unreasonable seal structure. The screw hole on the body of the press brake is designed as a through hole with no sealing measure. The press brake cover is not designed with a gasket. The clearance between the shaft and the body hole is too large. The interference between the sealing ring and the shaft does not meet the requirements. The design of sealing groove is unreasonable.
Oil leakage can be caused by casting defects and parts damage. The castings of the press brake have defects such as blisters, pores, cracks, and loose tissues. When the oil pipes and pipe joints of the press brake are made of plastic or oil-resistant rubber, the materials will age to become hard and brittle after long-term use. The moving parts will lose the sealing performance due to friction and wear. If the gap between the shaft and the shaft hole increases, it will also cause oil leakage.
Before maintaining or cleaning, the upper mold should be aligned with the lower mold. Shut down until the work is completed. If you need to start press brake, select the manual mode to ensure safety.
Check the oil level of the oil tank every week, even after the hydraulic system is repaired. If the oil level is lower, add hydraulic oil. The oil should be changed after 2000 hours of operating new press brake. Afterwards, the oil should be changed after 4000 to 6000 hours of operating press brake. The oil tank should be cleaned every time before changing the oil. The oil temperature of the press brake should be between 35℃ and 60℃ that is not exceed 70℃. Otherwise, it will cause deterioration and damage of the oil quality and accessories.
The filter of press brake should be replaced or thoroughly cleaned every time if the oil is changed. If the press brake has filter abnormalities such as unclean oil, the filter should be replaced. The air filter on the fuel tank should be inspected and cleaned every 3 months and replace every year.
After using the new press brake for one month, check whether the bending of each oil pipe is deformed. After two months of use, all fittings should be tightened.
The oil of the press brake plays the role of transmission, wear resistance, system lubrication, anti-corrosion, rust prevention, and cooling in the hydraulic system. It belongs to the industrial hydraulic system. The hydraulic oil itself is constantly changing in use. However, it is difficult to completely solve the problem of hydraulic oil pollution.
Serious oil pollution will directly affect the performance of the press brake. It will cause frequent failures of the brake system and shorten the lifespan of press brake.
The main reason is the particles in the dust. As far as hydraulic components are concerned, these solid particles entering the components will increase the wear of the sliding parts. In addition, it may block the orifice, the orifice in the hydraulic component, or the spool stuck, causing the hydraulic system to malfunction.
The mixing of water and air reduces the lubrication of hydraulic oil, accelerating the oxidation of hydraulic oil and producing cavitation corrosion.

The CNC press brake uses a servo motor as an actuator. When the bending operation is not performed, the motor does not move and consume power. Therefore, CNC press brake is a product that meets the energy saving requirements. The servo motor has a higher degree of controllability so that it can be well adapted to the production needs of the modern industry.
The efficiency and the profitability of a CNC press brake are measured by the number of completed and correct parts produced in a given period of time.
Operators need to know CNC press brake completely. They also should know material type, thickness, flange dimensions and tolerances, angles and angle tolerances, and inside radius of angles.
The choice of tool is based on the drawing. Air bending, bottom bending, and coining are available. Select the tool that is at least as accurate as the specified type.
Tonnage charts are available for air bending. For bottom bending, a good tonnage may be four times than that of the air bending. Coining requires eight times the air bend tonnage.
If you have two or more CNC press brakes, make sure to choose the best-suited one. Remember that air bending cannot overload a CNC press brake.
Determine tooling position on the bench. If the tonnage requirement exceeds the concentrated load limit in the center of the CNC press brake, it can be off-center.
Install the tooling and align the upper and lower.
CNC press brake should be programmed properly, which is very quick.
Bend materials only after completing a good test bend. If something wrong, correct the program until a good part has been formed.

V groover machine is a V-type slotting equipment designed for steel plate. V groover machine often plays a role as a sheet metal bending machine and cutting auxiliary equipment. It is widely used in the sheet metal V-groove, U-groove, and other irregular groove processing.
What are the types of V groover machines?
How to choose V groover machines?
How about the market situation of V groover machine?
The working table of vertical CNC V grooving machine is small and narrow. The planer is fixed in a straight-line position to the working table. Variable factors can be so well-controlled that the position accuracy is in the range of 0.02mm. When the vertical V groover machine is working, the holder part moves back and forth. Vertical V groover machines have many separate pressing plates and independent clamps. It can do both horizontal and vertical grooves. The surface is made of high-quality mold steel, which goes through overall heat treatment after a grinder refined.
The working table of horizontal CNC V grooving machine is larger and easier to work. The knife is facing a platform with 1.5 meters width and more than 4 meters length. The accuracy is lower. When the horizontal V groover machine is working, the gantry and the holder move back and forth together. Its energy consumption is more than 10 times than that of the vertical V groover machine. A horizontal V groover machine is available for large sheet metal. It cannot be able to horizontal gouging. The working table is welded by a common iron plate, causing spots on the processed products for long-term use.
When choosing a V groover machine, considering the materials such as steel bars, concrete walls, and stones. Once they are encountered, you must choose a diamond blade. With high hardness, it is widely used for cutting marble, steel bars, stones and other super-hard materials.
The power of V groover machine is an important indicator. In fact, it does not mean the higher the power the better the V groover machine. In the ordinary grid lines, it cannot withstand the 4000W power at all. Three-phase power is required to achieve smooth operation.
The size of the V groover machine motor determines its power. The larger the size of the motor, the greater the power. The power can be obtained by measuring and comparing the diameter of the stator and the length of the rotor.
Groove depth should be measured by two dimensions: the distance from the center of the tool shaft to the tool cover and the height of the tool beyond the bottom of the V groover machine. The larger the distance, the larger the diameter of the blade that can be installed. The higher the distance, the deeper the groove. It is best to choose V groover machine with deeper and wider grooves.
Also, you should choose a V groove machine that can adjust the depth of slotting to meet different demands.
Chins will continue to support the development of CNC V grooving machine. During the Fourteenth Five-Year Plan period, we will continue to invest the CNC industry greatly to elevate the cultivation of core competitiveness, innovate independently, integrate quantitatively and build brand.
Numerical control processing is the trend of high-quality, high-precision, high-yield, and high-efficiency development in the V groover machine industry. The good development trend shows that the demand is still at a high level. Companies should seize the opportunity and strive to realize the transformation of V groover machine from low-end to high-end, from primary processing to high-precision manufacturing.
