The steel bent by the CNC press brake has a relatively large advantage over the others. Because the residual stress of the steel material of the CNC press brake is relatively small with dense weld seam. The CNC press brake in the production practice produces section steel with very messy interface shapes, which is impossible for traditional processes.

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.

The CNC press brake is composed of a bracket, a workbench and a clamping plate. The gravitational force is generated by energizing the coil to the pressure plate, completing the support for the thin plate between the pressure plate and the base. Because of the electromagnetic clamping method, CNC press brake can bend the plate according to the specific requirements.
What is the structure of CNC press brake?
What materials can be bent by CNC press brake?
What affects the deflection of CNC press brake?
CNC press brake adopts hydraulic transmission and mechanical block. The cylinder is fixed on CNC press brake, while the piston rod is fixedly moved by hydraulic pressure. The mechanical block is used that the adjustment value is controlled by the environmental protection system.
Workbench of CNC press brake is designed by a button box. The retained intercepting material rack moves forward, whose distance is controlled by the control system. The minimum valve is about 0.01mm, which is limited by switch positioning of the front and rear position.
CNC press brake consists of a mechanical synchronization mechanism, which is composed of torsion shaft, swing arm, and joint motion. CNC press brake has simple structure, stable and reliable performance, and high synchronization accuracy. The mechanical stop is controlled by the motor to control the value of the system.
Material stopper mechanism used in CNC press brake is driven by a motor. The two screw rods move synchronously through chain operation.
The most commonly used carbon tool steels in CNC press brake are T8A and T10A. They are good at processing at low price. However, the harden ability and red hardness are poor. The heat treatment deformation is large with low bearing capacity.
As another common materials used in CNC press brake, low-alloy tool steel is based on carbon tool steel with an appropriate amount of alloying elements. It reduces the tendency of quenching deformation and cracking, improving the harden ability of steel. It has better wear resistance.
High carbon and high chromium tool steel
High carbon and high chromium tool steels are another important material used in CNC press brake. They have good harden ability and high wear resistance. The heat treatment deformation is very small. CNC press brake die steel is second only to high-speed steel in carrying capacity. However, the segregation of carbides is serious, which has to upset and forge again to reduce the unevenness of carbides.
Two working cylinders of CNC press brake are pressurized at both ends of the slider. The resultant force of the deformation of the workpiece is in the middle, so the worktable of the sliding block of CNC press brake will be flexed and deformed together with the upper and lower molds.
The sheet material will receive uneven force at various points along the length of the die edge, which directly affects the accuracy and straightness of the bent workpiece. To make up for this shortcoming of CNC press brake, a deflection compensation device can be installed.
Preset a deformation amount opposite to the force deformation direction between the press brake slider and the upper die. The amount of deformation is the same as the relative amount of deformation during actual work. The relative deformation of the slider and the worktable is compensated so that the pressure distribution between the dies is more uniform. CNC press brake improves the quality of sheet metal bending.
