The V-grooving machine, also known as the CNC V-cutting machine or V-groover, is mainly used to scribe and slot V-shaped grooves on stainless steel sheet metal, ordinary steel sheet metals, aluminum sheet metals, copper sheet metals, and aluminum composite sheet metals under 8mm before bend forming. Thus, it can reduce the bending radius and improve the appearance of sheet metal workpieces. 

The workpiece produced with this technique has a small bending radius, no obvious color changes, and small bending force requirements. In addition, it reduces the straightness error of the round edge of narrow long workpieces, and the common press brake and tooling can be used to bend the workpiece with a complicated section shape.
Why should workpieces be v-cut before bending?
● The bending radius of the workpiece should be small;
● The bending angle of the workpiece bending with stainless steel titanium sheet metal or other colored metal sheet metals should not have serious color changes;
● No obvious color difference is allowed;
● The curved section of the workpiece is more complicated;
● The unique style of the designer should be displayed.
Traditional bending methods such as forced bending, free bending, and even three-point bending have been unable to meet the above requirements.
In other words, bending the metal sheet with a press brake alone cannot meet the design requirements of the designer and cannot achieve the grade and decorative effect of middle and high-grade decoration.
Therefore, a novel bending technique has been developed, which is V-groove bending technology.

Before the development of special V-grooving equipment, workshops generally used planers to make V-shaped grooves on metal sheet material. However, because the planer lacks an effective metal sheet pressing device, the V-grooving depth of the metal sheet and the positioning distance of the V groove cannot be precisely controlled. Additionally, planers have high energy consumption and low efficiency.

Currently, V-grooving for metal sheets is accomplished with a new type of metal sheet grooving machine designed and manufactured according to the special needs of the middle and high-end decoration industry and elevator manufacturing industry. This machine can make V-shaped grooves for materials such as stainless steel sheet, iron sheet metal, and copper sheet metal. With the installation of specially dedicated accessories, the metal sheet V-grooving machine can also be used for grinding, polishing, and drawing of metal sheet materials and profiles.

The machine tool is particularly useful in industries requiring high-precision sheet metal processing, such as elevator manufacturing, packaging materials, stainless steel metal processing, security doors, cabinets, household appliance production, metal furniture and prop display.
With the development of the economy, places such as hotels, restaurants, shopping malls, banks, and airports have an increasing demand for metal decorative materials with bend forming in middle and high-grade decoration.

First, adopt the V-grooving (or V-cut) method on the metal sheet. Then, bend the grooved sheet metal into various angles and shapes using a press brake with a general mold or special mold.
Such a curved workpiece can meet the special needs of high-end decoration in hotels, restaurants, shopping malls, banks, and airports.
The main equipment of v-groove bending technology is press brake and sheet metal V-groover (also been called V-grooving machine).
The press brake is a traditional plate bending machine, and the thin sheet metal V-grooving machine is a new type of sheet metal processing machinery, which is the key equipment of V-cut bending technology.

The basic principles of the metal sheet grooving process are as follows:
A)  The metal sheet metal is fixed, and the V-groover blade mechanically cuts the metal material on the movement track to form a V-groove.
B)  The size of the bending angle is related to the depth of the V-groove.
C)  The smaller the bending angle, the greater the value of the V-groove depth that needs to be grooved.

(1) Maximum width and length of the slotted sheet:
(2) Maximum thickness of the slotted sheet:
(3) The minimum distance of the V-shaped groove from the edge:
(4) Cutting speed:
(5) Left and right, up and down movement resolution, and positioning accuracy of the tool holder:
(6) blade.
The quality and number of blades directly affect the machining efficiency and the speed of tool wear.
Traditional grooving equipment uses three blades for simultaneous cutting, and current technology uses four blades for simultaneous cutting.

The models for v grooving machines manufactured by us are: horizontal/gantry/vertical/four-side 1250mm*3200mm, 1250mm*4000mm, 1500mm*3200mm, 1500mm*4000mm, 1250mm*6000mm, 1250mm*8000mm, 1500mm*6000mm, 1500mm*8000mm. And we can customize the worktable size to the customer’s special need.
The most popular modem is 1250×4000(W*L) V grooving machine.

Due to the obvious advantages of V-shaped groove bending technology, and the fact that the traditional bending method and equipment do not need to be changed, only the sheet metal V-grooving machine needs to be added, so V-grooving bend forming technology has been widely used in the emerging middle and high-grade decoration industry in the first place.
It was then adopted in elevator manufacturing.
Next, some experts in medical device manufacturing and electric control cabinet manufacturing industry also showed their interest in V-grooving bend forming technology.
It can be seen that with a deep understanding of the V-grooving bend forming technology, the application field of this technology will be broader.
