The V-groove machine is a special equipment for processing V-grooves on sheet metal. It is a sheet metal processing machine that is widely used in manufacturing and metal processing.
The V-shaped groove machine cuts V-shaped grooves on the surface of the metal sheet through a special cutting tool. These grooves can be straight or curved, depending on the design of the cutter and the setup of the cutting path. The workpiece produced by this technology has a small bending radius, no obvious color change, and requires little bending force. In addition, the straightness error of the round edge of the narrow and long workpiece is reduced, and ordinary bending machines and tooling can be used to bend workpieces with complex cross-sectional shapes.
And it is suitable for various metal materials, such as steel plate, stainless steel plate, aluminum plate, etc. Sheet metal of different thicknesses and sizes can be processed. V-groove machines usually have high cutting accuracy, which can ensure accurate V-groove cutting to meet the design requirements.
Some advanced V-groove machines are equipped with automated features, including CNC control and automatic tool adjustment, making operation easier and increasing productivity.
V-groove machines have important applications in the manufacture of metal parts, special sheet metal processing and the production of metal components with V-shaped bending structures. These slots can be used to bend and bend metal materials, giving components greater strength and stability. In addition, V-shaped grooves can also be used for splicing, connecting and assembling different metal parts, providing a stronger combination.
The V-groove machine can cut V-shaped grooves in sheet metal, which can strengthen and guide when bending. By cutting V-shaped grooves on the bending line of the metal plate, the bending at the bending point is more uniform, reducing the risk of deformation and cracking, thereby improving the bending strength and quality of parts.
It can also be used to join multiple metal sheets, aligning them precisely and fastening them together, e.g. by welding. This method of splicing is especially useful when making large structures and containers, increasing the strength of the joints and improving the stability of the overall structure.
And can be used to cut grooves and trenches that can be used to hide cables, conduits or pipes, making these elements neater and safer in sheet metal structures. In some special designs, V-shaped bending structures are required to achieve specific functions or aesthetic effects. The V-shaped groove machine can cut the metal plate into a V shape, and then process it into a V-shaped bending structure through bending and other processes.
V-shaped groove machines play a key role in sheet metal processing, helping to strengthen the structure of parts, improve bending strength, realize the splicing and connection of metal sheets, and create special V-shaped bending structures to meet various application requirements .
First, fix the metal sheet to be processed on the workbench of the V-groove machine. Fixing the material is a key step to ensure that the metal plate does not move or shake during the cutting process to ensure the accuracy of the cut. According to the size and shape of the V-groove to be processed, select the appropriate cutting tool. The cutting tool may be a cutting blade or a cutting tool with a V-shaped edge, the shape of which matches the V-groove to be cut.
Adjust the cutting depth and angle of the V-groove machine to suit different processing requirements. The depth of cut determines the depth of the V-groove, and the angle determines the opening angle of the V-groove. Start the V-groove machine, the cutting tool moves along the predetermined path, and forms a V-shaped groove by cutting the surface of the metal plate. During the cutting process, a part of the metal plate is removed by the cutting action of the cutting tool, thereby forming a V-shaped groove.
Finally, when the cutting tool finishes cutting along the set path, stop the operation of the V-groove machine. Then, take out the cut metal plate to complete the V-groove process.
Manual V-groove machine: The manual V-groove machine requires the operator to manually control the movement and cutting depth of the cutting tool, which is suitable for some simple V-groove processing requirements.
Semi-automatic V-groove machine: In the cutting process of semi-automatic V-groove machine, the movement of the tool and the cutting depth are partly controlled by the operator, but it may be equipped with some automation functions, such as automatic tool adjustment or automatic feeding function, which improves the processing efficiency and accuracy .

Mechanical V-groove machine: The mechanical V-groove machine adopts mechanical transmission mode, and the movement of the cutting tool is realized through transmission devices such as gears and belts, which is suitable for some small and medium-scale V-groove processing needs.
Small bending force requirement: By performing V-shaped cutting on the plate at the bending position, the required bending force is reduced, and the thickness of the plate is effectively reduced. The depth of the V-groove is half the plate thickness, thus saving up to 50% of the bending force.
The bending radius of the workpiece is small: V-groove processing reduces the thickness of the plate at the bending position, and the bending radius of the workpiece is naturally reduced proportionally. Within the range of sheet strength, the thinner the remaining thickness, the smaller the bending radius of the workpiece.
The color change of the curved round edge of the workpiece is small: through the V-groove processing of the plate, the thickness of the plate at the bending point is reduced, and the elongation deformation caused by the transverse tension during bending is also reduced, so that the color change of the curved round edge of the workpiece is small. the goal of.
The straightness error of the curved round edge of the narrow and long workpiece is small: the V-shaped groove bending forming technology minimizes the straightness error of the edge line of the narrow and long workpiece, and by reducing the bending deformation, the central concave shape of the edge line is also reduced.
The advantage of the V-groove bending process is that it can reduce the thickness and bending radius of the workpiece, improve the bending effect of the workpiece, and is suitable for workpieces of different shapes and sizes, improving the flexibility and efficiency of processing.
Due to the obvious advantages of V-groove bending technology, and there is no need to change the traditional bending methods and equipment, only need to increase the sheet metal V-groove machine, so the V-groove bending technology has been widely used in the emerging middle and high-end decoration industry application.
Subsequently, this technology was successfully applied to the elevator manufacturing industry. Due to the advantages of the V-groove bending process, the manufacture of the elevator shell is more efficient, precise, and has a better appearance.
Next, some experts in medical device manufacturing and electric control cabinet manufacturing industries also showed strong interest in V-groove bending forming technology. In the manufacture of medical devices, the V-groove bending process can be applied to the processing of various parts to improve product quality and performance. In the manufacture of electrical control cabinets, the V-groove bending technology can achieve a more refined and complex bending structure, improving the strength and durability of the cabinet.
With the in-depth understanding of V-groove bending forming technology, people find that its application fields will be broader. In addition to the above industries, V-groove bending technology can also be used in aerospace, automobile manufacturing, rail transit and other fields, as well as various engineering, architectural decoration and other fields.

Whether to choose a horizontal V-groove machine or a vertical V-groove machine depends on the specific processing requirements and usage scenarios. Here are some comparison points to help you choose:
Horizontal V-groove machine:
It is suitable for larger sheet metal processing, because horizontal V-groove machines usually have larger workbench and processing space.
For larger size workpieces, it can be easily operated without flipping or adjusting the position of the workpiece.
It is suitable for situations where longer V-groove cutting is required, because its long table length can continuously cut long sheet metal.
Vertical V-groove machine:
Suitable for smaller sheet metal processing, vertical V-groove machines are often compact and suitable for workplaces with limited space.
Multiple operations are required for smaller sized workpieces because the relatively small worktable cannot handle larger sheet metal in one go.
Suitable for situations where shorter V-groove cuts are required, where the table length is limited and the workpiece position may need to be adjusted several times to complete longer cuts.
other factors:
Equipment cost: Horizontal V-groove machines are typically bulky and complex, and therefore can be more expensive than vertical V-groove machines.
Production efficiency: The horizontal V-groove machine may have higher production efficiency when processing large batches of workpieces due to its larger workbench and processing space.
Processing accuracy: Due to its relatively compact structure, the vertical V-groove machine may be slightly better than the horizontal V-groove machine in terms of processing accuracy.
Comparison of the two technologies
| thing | Vertical V-shaped slotting machine | Horizontal V-shaped slotting machine |
|---|---|---|
| Processing range | It is suitable for workpieces that need to be grooved around, but for longer workpieces, an additional workbench is required to carry them when processing the short side, and the operation is not very convenient. | It is suitable for workpieces of various large sizes and shapes, and has three-axis CNC machining capabilities. |
| Workbench processing technology | The surface of the workbench is made of high-quality mold steel, which has undergone overall heat treatment and fine grinding with a grinder, and the surface finish has reached a mirror effect. | The surface of the worktable is welded by ordinary iron plates, but the hardness of the workpiece is higher than it. The work surface needs to be restored periodically because the grooved wires and blades can damage the work surface. |
| Processing efficiency | The minimum distance between the V-shaped groove and the edge is 10mm, and the cutting speed is 40m/min. | The minimum distance between the V-shaped groove and the cutting edge is 8mm, and the cutting speed is 50m/min or higher. No reciprocating feeding is required, and the efficiency is higher. |
| power loss | The front and rear movement loss of the tool holder is small, and the power of the main motor is 4.4kW. | The gantry and the knife rest move back and forth together, and the loss is large, and the power of the main motor is 5.5kW. |
| Safety | Adopt hydraulic automatic clamping workpiece, automatic positioning, automatic work, the operator is far away from the moving parts of the machine, improving safety. | The workpiece is clamped within the range of motion of the machine tool, and the gantry moves at high speed, so the operator must pay attention to safe use. |
| overall effect | Since the workpiece needs to be automatically fed after clamping, the iron filings generated by the grooving often scratch the decorative surface. When processing large-sized workpieces, frequent alignment and movement are required, which is more likely to damage the surface. | The workpiece does not need to be moved during the processing, and the whole process can be operated by one person to ensure that the decorative surface of the workpiece will not be scratched and the surface processing quality is guaranteed (an important reason for use in the elevator industry). |
