- The edge radius of the bent workpiece is small and has no refraction. According to the bending process, the edge radius of the bent workpiece is directly proportional to the thickness of the bent workpiece. Due to the V-shaped slotting of the metal sheet, the thickness of the remaining sheet is only half of the original sheet thickness, or even smaller, resulting in a proportional reduction of the edge radius of the bent workpiece. Also, because the thickness of the remaining sheet metal after V-shaped slotting is small, the deformation force during bending is also small, and it will not diffuse and affect the unbent area, so there is no refraction on the surface of the bent metal sheet workpiece.
- The bending force required for sheet metal bending has been reduced. According to the bending process, the bending force of the sheet metal is directly proportional to the thickness of the bent workpiece. Before bending, a V-shaped groove is made on the metal sheet to reduce the remaining thickness of the sheet metal to about half or less of the original thickness. This also reduces the bending force required for sheet metal bending, allowing long sheets to be bent on smaller tonnage bending machines. It can reduce equipment investment and save energy.
- Some special material types can be bent into rectangular tubes using universal molds on ordinary bending machines, which cannot be bent into shapes on ordinary bending machines or require complex molds with special designs to complete the work. However, by controlling the depth of the V-shaped groove on the metal sheet, this special bending material can also be bent and formed using a universal mold on a regular bending machine.
- Positioning the bending edge size before bending can be achieved by performing a shallow V-shaped groove on the metal sheet. This can be used to pre-position the bending edge size before bending, and then bend it on the bending machine according to the pre-engraved V-shaped groove. This ensures the accuracy of the bending edge size and can replace the backstop function of the CNC bending machine.
Before the specialized stainless steel V-grooving equipment was available, gantry planers were commonly used to perform stainless steel v grooving v-groove on metal sheet materials. Due to the lack of reliable and effective metal sheet pressing devices, the depth and positioning distance of the stainless steel V-grooving on the metal sheet cannot be controlled. In addition, the energy consumption and low efficiency of operating the gantry planer are various factors. Currently, the stainless steel v-grooving work on metal sheets has been replaced by metal sheet planers.
