CNC V-grooving channel milled into stainless steel sheet before bending

The difference is in the edge

Laser → V-groove → bend → weld → finish → inspect. One chain, one workshop, your drawing.

V-grooving vs normal bending

Precision sheet metal job work · Narela, Delhi · since 2001

Precision in
every fold.

From flat sheet to project-specific part. MCS turns your drawing into precise sheet metal components: CNC V-grooving, precision bending and CNC fibre laser cutting, backed by in-house design, welding, finishing and inspection. For fabricators, contractors, architects, PMCs, makers and developers across India.

The difference is in the edge

Same sheet. Same fold.
Different corner.

Folded stainless steel channel with a round outside corner, bent on a press brake without V-grooving
Ordinary bendingThe outside corner comes out round.
Folded stainless steel channel with a sharp 90° outside corner, V-grooved before bending
V-grooved, then bentThe outside corner closes to a sharp 90°.

Ordinary bending

A press brake wraps the sheet around its tool, so the outside corner comes out round. Efficient and right for hidden parts: sub-frames, carriers, brackets.

V-grooved, then bent

We first mill a V-shaped groove along the bend line and leave a thin web of metal. The sheet folds into the groove and the corner closes to a sharp edge.

When to choose which

Where a corner is seen from close by, V-grooving pays. Where it is hidden, ordinary bending is enough and costs less, and we tell you so.

Show us what you need to make

Send a drawing, a DXF, a sketch, a photograph or a sample. Our design team reviews it, plans the route through our machines (laser cutting, V-grooving, bending, welding, finishing) and makes a sample for your approval. Production then repeats it, with the delivery date committed in writing.

Design desk, fibre laser, V-groover, press brake, welding, finishing, inspection, packing and dispatch, in one 20,000 sq ft workshop in Narela, Delhi. No part leaves the building between steps, so the first sample and the last length match.

How a job runs

From drawing
to dispatch

01Send the drawingA DWG, DXF or dimensioned PDF, the metal, thickness, finish and quantity. A sketch is enough to start a new product.
02Design reviewOur design and planning team checks bend order, groove positions and flat lengths, and tells you what will work best before anything is cut.
03SampleWe make a sample on the production machines. You approve it, so the corner and the section are agreed.
04ProductionWe laser cut, V-groove, bend, weld and finish the order on the same machines, so the last piece matches the sample.
05Committed deliveryThe delivery date is committed in writing with every order.

Custom development

Have an idea?
Let’s develop it.

Bring an idea, a sketch, a photograph, a sample or a drawing. Our in-house design and planning team works out how it can be made in sheet metal, makes a prototype on the production machines, and takes it into production once you approve it.
