HOW TO SOLVE THE PLASMA CUTTING GROOVE PROBLEM?

 There are many plasma cutting characteristics, groove is one of them. If the groove is too large, it will bring inconvenience to the subsequent treatment of steel. In this phase, the groove problem will be analyzed and solved.

Gusheng TechnologyUnder normal cutting conditions, the ideal working pressure of plasma should be between 0.4-0.6mpa. The longer the cutting torch cable, the larger the cutting nozzle aperture and the thicker the processed plate, the higher the pressure requirements. Too low air pressure will lead to weak cutting capacity, overheating and melting will occur when the plate is cut, resulting in large and unsightly cuts, and a large amount of slag hanging under the plate. Similarly, too slow cutting speed and too large cutting current will also lead to slag hanging.
The plasma cutting height is about 5mm, which varies slightly according to the material and the type of cutting torch. When the speed, current and air pressure are set reasonably, different cutting heights and angles will also lead to groove.

Figure ① shows the normal cutting, with a cutting distance of about 5mm and a small amount of welding slag.

Figure ② shows that there is an inclination angle between the cutting torch clamp and the steel plate, resulting in the inclination of the groove in one direction. When the air passage inside the cutting torch is damaged or there is a gap in the cutting nozzle, because the air flow can no longer be blown down vertically, the groove will also tilt in one direction.

Figure ③ and figure ④ show that if the cutting torch is too high or too low, it will also lead to abnormal incision. On the CNC plasma cutting  machine with arc voltage regulator, the cutting height is inappropriate, which is mainly caused by the setting of the arc voltage value is too large or too low.
Under normal cutting conditions, increasing the cutting air pressure, reducing the cutting speed, and replacing the plasma and cutting torch with higher precision can effectively reduce the groove phenomenon.

what is the hand-held laser cutting machine? and what is the advantage of the laser cutting machine?

图片
With the improvement of welding flexibility and precision processing requirements in the field of sheet metal processing, traditional argon arc welding, secondary welding and other ordinary welding machines can no longer fully meet the needs of production, and handheld laser welding comes into being! It improves welding defects such as undercut, incomplete penetration, dense pores and cracks in the traditional welding process. The weld seam after hand-held laser welding is smooth and beautiful, which reduces the subsequent grinding process, saves time and cost, and Less consumables, long life, popular in the market. Hand-held laser welding machine is a kind of equipment that can be operated portablely. It is also a precision welding equipment, but it can be used freely and flexibly in various environments. For some production supplementary operations and packaging management, it is suitable for various It can be conveniently applied in different types of environments, and has the cha

How to save the packing cost when use jumbo bag?

Learn these methods of loading and unloading jumbo bags , and your packaging cost will be greatly reduced!  1.good loading method Before loading, the container bag is usually suspended with a lifting device, and the bottom of the bag contacts the ground or tray, and then the material opening of the container bag is opened, sleeved into the loading cylinder and clamped to prevent dust or particles from leaking out. Start the filling machine to load the raw materials into the bag from the loading port. During filling, the bag body needs to be straightened before operation.After filling, close the discharge port. If the container bag has a discharge port or other discharge parts, check whether it is fastened or closed before loading. 2.Stacking stability The height of the filled container bag should be 0.5 ~ 2 times the minimum side length (rectangular bottom) or bottom diameter (circular bottom) of the container bag bottom, so that the container bag is relatively stable when stacked.

HOW TO CHOOSE LASER CUTTING MACHINE

图片
  Plate and tube integrated laser cutting machine is also called plate and tube laser cutting machine . It can cut both metal plates and metal pipes. At present, there are mps-3015dt, mps-3015ct and other plate and tube integrated laser cutting machines. In the metal processing industry, the application of the plate and tube integrated laser cutting machine is more and more extensive. Many metal processing manufacturers have both the demand for processing metal plates and the demand for processing metal pipes. The plate and tube integrated laser cutting machine is naturally the first choice. It can not only meet the processing needs of customers, but also save the cost of equipment procurement. Why not use one machine for multiple purposes? Everyone will pay attention to the price of the plate tube laser cutting machine. When we purchase it, we are often confused. Then, how can we choose a reasonable price, good performance and cost-effective equipment? Let’s talk today. First of all,
