Sales Of Gantry & Vertical CNC V-Grooving Machines for Precision Sheet Metal Bending

CAMT V-grooving machines are designed for modern sheet metal processing, creating precise, burr-free V-shaped grooves on stainless steel, aluminum, carbon steel, copper, and composite sheets. These clean grooves make it easier to achieve sharp, near-zero-radius bends and accurate 90° or acute angles on the press brake, while helping reduce cracking, deformation, and post-bend grinding.

Types Of CAMT V-Grooving Machine

HMG Series Gantry V Grooving Machine

The HMG series adopts a gantry-style high-rigidity frame with a bolted structure, helping the machine maintain long-term stability and reduce deformation during continuous work. With CNC-controlled automatic feeding and practical tool management, it is well suited for large-format sheets and higher-volume precision grooving jobs. Working lengths start from 3200 mm and can be customized, making this series a strong choice for applications that require consistent flatness, accurate groove depth, and reliable repeatability across repeated production.

HMV Series Vertical V Grooving Machine

The upgraded HMV vertical series combines a heavy-duty frame with improved speed, rigidity, and processing stability for daily production use. Its compact but powerful layout is especially suitable for stainless steel and alloy sheets in medium to large batch manufacturing, where consistent groove quality and efficient cycle times are important. Common working sizes range from 1250×3200 mm to 1600×6200 mm, giving workshops greater flexibility to handle different panel sizes while maintaining precise, repeatable V-grooving results.

Key Advantages of CAMT V-Grooving Machine

Achieve Sharp Bends Without Surface Cracking

When bending stainless steel or coated sheets directly, surface cracks, wrinkles, or large bend radii are common problems. CAMT V-grooving machines create precise grooves along the bend line, reducing local thickness so the sheet can form sharp 90° or acute angles with much less risk of cracking or deformation.

Reduce Post-Bend Grinding and Rework

Poor bend appearance often requires extra polishing or grinding, increasing labor cost and production time. By producing clean, burr-free V-grooves, our machines help improve the final edge quality after press brake forming and significantly reduce secondary finishing work.

Improve Bend Consistency Across Batches

Inconsistent bend angles and springback make assembly more difficult. With CNC control and groove depth accuracy within ±0.02 mm, CAMT V-grooving machines help maintain stable groove depth and angle consistency, supporting more repeatable bending results from the first piece to the last.

Better Results on Decorative and High-Appearance Parts

For elevator panels, kitchen equipment, doors, and architectural sheets, surface quality is critical. Precise pre-grooving helps achieve neat corners and cleaner visual lines, improving the overall appearance of finished products without relying on heavier forming force.

Lower Bending Force Requirements

Thick or high-strength sheets usually need higher press brake tonnage and place more stress on tooling. After V-grooving, the required bending force is reduced, making forming easier, protecting tooling, and improving process stability on medium-thickness sheets.

Flexible Processing for Different Panel Needs

Workshops often handle different groove angles, depths, and panel sizes. CAMT machines support multi-pass processing, variable groove angles, and programmable control, making them suitable for both customized jobs and medium-to-large batch production on stainless steel, aluminum, and similar materials.

FAQs When Purchase V-Grooving Machine

What is a V-grooving machine used for?

A V-grooving machine cuts precise V-shaped grooves on sheet metal before bending. This helps achieve sharper bends, smaller radii, better appearance, and less surface cracking during press brake forming.

Which materials are suitable for V-grooving?

It is commonly used for stainless steel, aluminum, carbon steel, copper, and some composite decorative sheets, especially thin to medium sheets around 0.5–4 mm.

Why do I need V-grooving before bending?

Without grooving, thick or stainless sheets may show large bend radii, surface marks, cracks, or unstable angles. Pre-grooving reduces local thickness at the bend line and makes sharp, clean forming much easier.

What is the typical groove depth accuracy?

CAMT V-grooving machines are designed to maintain groove depth accuracy within about ±0.02 mm, which helps keep bending results more consistent.

What is the difference between gantry and vertical V-grooving machines?

Gantry models are better for large-format sheets and higher stability in continuous precision work. Vertical models offer a more compact layout and are practical for medium to large batch production in standard workshops.

Can V-grooving replace special press brake tooling?

In many cases, yes for sharp-angle and small-radius forming. After proper grooving, standard press brake tooling can often complete bends that would otherwise require special tools or multiple corrections.

Will V-grooving damage the surface of decorative sheets?

When parameters and tooling are set correctly, the groove is formed cleanly with minimal burrs. This is one reason V-grooving is widely used for elevator panels, kitchen boards, and other appearance-critical parts.

How much can bending force be reduced after grooving?

It depends on groove depth and material thickness. In many applications, reducing thickness at the bend line can lower required bending force substantially, making forming easier and reducing stress on the press brake and tooling.

What groove angles can the machine process?

CNC V-grooving machines generally support programmable and variable groove angles, not only a fixed V shape, so different bending requirements can be matched more flexibly.

Is multi-pass grooving necessary?

Yes, multi-pass processing is commonly used. Cutting the groove in several passes improves surface finish, depth control, and process stability, especially on stainless steel.

What industries benefit most from V-grooving machines?

Typical industries include elevator manufacturing, kitchen equipment, door panels, decorative architectural metalwork, electrical enclosures, and precision sheet metal workshops that need sharp and clean bends.

Can one machine handle different sheet sizes?

Yes. Different models offer different working lengths and widths. Choosing the right size according to your main panel dimensions is important for both efficiency and stable processing.

How does V-grooving improve final product appearance?

It helps create sharper corners, straighter bend lines, and cleaner surfaces after forming, reducing visible deformation and the need for heavy polishing.

What should I prepare before buying a V-grooving machine?

Prepare your main materials, thickness range, panel size, groove depth/angle requirements, daily output, and whether the parts are appearance-critical. This helps select the right machine structure and working size.

What support is important after installing a V-grooving machine?

Key support includes process parameter guidance, tooling advice, groove depth setting, operator training, and timely help for quality adjustment during trial production.
