What Is a V-Grooving Machine?
A V-grooving machine cuts a precise V-shaped groove along the bend line of a sheet, leaving a thin web of material at the base. The sheet then folds by hand or on a light brake into a sharp, clean inside corner with little springback. It is widely used for architectural panels, elevator and lift interiors, cabinets, signs and stainless steel furniture where a crisp, tight-radius edge matters.
RAGOS NVA Series
The NVA Series is a high-end CNC grooving machine. The body is a full steel plate welded structure that is tempered to keep deformation small, and the CNC makes the process fully automatic. The system combines electric and pneumatic elements for easy operation, flexible action, high efficiency and low noise, with no environmental pollution.
- Eight double-headed cutters: make programming easier and reduce tool changes
- Hydraulic clamping plate: holds the sheet for precise positioning while it is grooved
- Control: Wonder CNC200 with a programming interface and a working interface
- Precision: ±0.01 mm resolution on the feed and tool-holder axes

Pair V-Grooving With Your Other Equipment
Feed the machine with blanks from an HSG fiber laser, then finish folds on a RAGOS press brake or panel bender. Tell us your materials and thicknesses and we will recommend the right size. Leasing is available.
Frequently Asked Questions About V-Grooving Machines
What materials can a V-grooving machine process?
V-grooving is commonly used on stainless steel and other sheet metal for bending with sharp inside corners. The NVA Series handles sheet from 0.5 mm to 6 mm thick. Tell us your material and thickness so we can confirm suitability.
How long a sheet can the NVA machines handle?
The NVA-3200, NVA-4200, NVA-5200 and NVA-6200 groove lengths of 3,200, 4,200, 5,200 and 6,200 mm, with sheet width from 10 mm to 1,600 mm.
Why groove a sheet before bending?
Grooving removes material along the bend line, so the sheet folds with a sharp inside corner and little springback. It also lets lighter equipment make clean folds on parts that would otherwise need a press brake.
What control does the NVA use?
A Wonder CNC200 control with programming and working interfaces. Operation is fully automatic once the program is set.
How much floor space does an NVA need?
The NVA-3200 is about 4.6 m long and 3 m wide, and the NVA-6200 about 7.4 m by 3.3 m. Exact outline and weight are in the table above.
Are these specifications final?
