Applications

V-grooving applications for formed sheet

V-grooving prepares a bend line before forming. Specify the final appearance and the structural needs of the part alongside the groove geometry.

Folded metal cladding and vertical trim on a building facade

Architectural trim and cladding

Visible corners and long exposed edges need a defined finish after bending. Review the groove plan and the complete formed profile together.

Selection focus: corner appearance and consistency along the edge.

V-grooving cutter assembly positioned over a finished metal sheet

Decorative panels and covers

Coated or finished sheet needs a handling and clamping plan that protects the visible face through loading, grooving and bending.

Selection focus: surface condition and support at the groove.

Examples of folded metal profiles with sharp corner geometries

Long folded profiles

Multiple grooves must align with the downstream bend sequence. Sheet support and loading space affect the choice between horizontal and vertical layouts.

Selection focus: datum, groove position and workshop flow.

Buying guide

Assess the finished bend, not just the groove

An effective grooving project connects cutter setup, remaining material and downstream forming.

Groove geometry

Define the angle, depth and remaining web with the part requirements in mind. Use a formed sample to assess the result.

Handling and finish

Include loading, face protection, clamping and chip removal in the workflow. Show which surfaces remain visible after assembly.

Cutting tools and upkeep

Clarify the cutter arrangement, consumables and maintenance requirements. Confirm the measurement method used to check the groove.

FAQs

V-grooving machine buying questions

Connect the groove specification to the final bend, visible finish and workshop layout.

Why V-groove sheet metal before bending?

A V-groove reduces the material thickness locally along a planned bend line and can help produce a tighter-looking corner. The finished appearance depends on the groove, material and bending process. Specify the final formed part as well as the groove itself.

Should I choose horizontal or vertical V-grooving?

ADHK uses a horizontal supported-sheet and moving-tool workflow. The ADRK proposal uses a side-standing sheet arrangement. Compare the actual sheet dimensions, loading access, surface contact and workshop layout for the chosen model, then check how the part moves to bending.

Review horizontal V-grooving Review vertical V-grooving

How are groove angle and depth selected?

Select the cutter and groove geometry around the required bend and remaining material. Sheet thickness, flatness, material behaviour and the downstream tooling all matter. Agree the remaining web and inspect a formed sample; there is no single groove depth or angle that suits every part.

Does V-grooving change the strength of the part?

Removing material changes the local section at the bend. The remaining thickness and formed geometry need to meet the part’s structural requirements. For load-bearing work, include an engineering assessment and suitable finished-part checks when deciding whether a grooved bend is appropriate.

What matters when processing decorative or coated panels?

Identify the visible face and the acceptable finish before choosing the handling arrangement. Review loading, clamping, surface contact and chip removal with representative material. Inspect the finished bend and visible surfaces together, including any coating or protective film used in production.

What should I send for a V-grooving recommendation?

Start with your material, thickness, sheet size and finished-part drawing. Add groove layout, surface requirements and a formed sample when available.
