Grooving machine

In the modern sheet metal processing process, the grooving stage plays an important role in creating precise bends, sharp angles, and high aesthetic surface finishes. CNC grooving machines were born to meet this requirement – helping factories reduce errors, optimize processing time, and improve product quality in industries such as electrical cabinets, elevators, stainless steel furniture, or precision mechanics. Currently, Weldcom is a pioneer in Vietnam in providing modern CNC grooving machines that meet international standards, easily integrate into automated production lines, helping businesses increase productivity and reduce operating costs.

1. What is a grooving machine?

• Grooving machines are specialized equipment in the sheet metal processing industry, helping to create V, U, or triangular grooves on the surface of metal sheets such as stainless steel, steel, aluminum...
• The purpose of the grooving stage is to prepare for the bending process, helping the edges achieve precise angles, sharp folds, and not crack the surface. As a result, the product has higher aesthetics, especially in fields requiring exquisite finishes such as electrical cabinets, stainless steel furniture, elevators, or high-end industrial equipment.
• With the development of CNC technology, today's grooving machines have automatic control capabilities, allowing precise programming of depth, angle, and groove position, delivering superior performance and high stability in mass production.

2. Advantages of CNC grooving machines in sheet processing

CNC grooving machines are considered an important technological advancement in the sheet metal processing line, helping businesses enhance accuracy, aesthetics, and production automation. Below are the most outstanding advantages:

• High precision processing: With the CNC control system, grooving machines can create grooves at absolute precision in depth, angle, and position (error only ±0.05mm), helping the bends meet technical standards.
• Enhance product aesthetics: Smooth, even grooves help details after bending have a seamless surface, not cracked or deformed – particularly important with decorative stainless steel, high-end furniture, and fireproof doors.
• Save time and materials: Grooving before bending helps reduce the necessary pressing force, save energy, and reduce wear on bending tools, while allowing processing of thicker metal sheets.
• Automation and smart operation: CNC grooving machines can pre-program multiple programs, store product parameters, automatically recognize workpiece positions, reducing dependence on operator skills.
• Easy integration into automated lines: Can connect directly with feeding robots, conveyors, or the SmarLineiQ system in smart sheet processing lines developed by Weldcom.

3. Classification of grooving machines

Depending on the working structure and cutter arrangement, grooving machines in sheet metal processing are divided into two main types: horizontal grooving machines and vertical grooving machines.

3.1. Horizontal Grooving Machines

• This is the most popular type today, widely used in large sheet processing factories.
• Structure & working mechanism: The material sheet is placed horizontally on a fixed table, while the cutter assembly moves horizontally to create grooves.

Advantages of horizontal grooving machines:

• High stability and precision, minimizing vibrations during grooving.
• Suitable for large or thick sheets, such as carbon steel, stainless steel, aluminum.
• Provides smooth groove surfaces, even and beautiful angles.

Applications of horizontal grooving machines:

• Processing electrical cabinets, elevators, stainless steel doors, control cabinets, metal panels.
• Products requiring high precision and aesthetic surface finishes.

3.2. Vertical Grooving Machines

• This type is more suitable for medium and small mechanical workshops or thin, complex sheet details.
• Structure & working mechanism: The cutter moves vertically, while the workpiece is clamped vertically.

Advantages of vertical grooving machines:

• Saves workshop floor space, easy to observe during grooving.
• Suitable for small details or deep grooves.
• Flexible angle adjustment options for thin materials.

Applications of vertical grooving machines: Processing stainless steel furniture, decorative panels, door frames, thin sheet details requiring high sophistication.

4. Applications of grooving machines in production

Thanks to the ability to process accurately and flexibly on various materials, CNC grooving machines are increasingly widely used in sheet metal production industries, especially: 

• Electrical cabinet & industrial equipment industry: Create precise grooves for bending cabinet shells, panels, electrical cabinet frames, ensuring sharp, tight, and aesthetic bends.
• Elevator, HVAC & electromechanical industry: Processing stainless steel, galvanized steel details for elevator cabins, air ducts, covers, ensuring high precision during assembly.
• Metal furniture & stainless steel decoration industry: Grooving machines help create delicate bends, no surface cracks, providing a smooth effect for stainless steel walls, cabinets, tables, chairs, bars, high-end stainless steel doors.
• Fireproof door and technical door production industry: Ensures solid, precise, non-deforming bends that meet high technical standards.
• Precision mechanics & thin structure processing: Applied in details requiring high precision bending, supporting the assembly process in electrical – electronic equipment production, control cabinets, and industrial mechanical systems.
