Cardboard V Grooving Machine

Whether you are producing rigid boxes/hardcovers, creating customized cartons, or designing attractive packaging cases, the cardboard V grooving machine could be your good helper, helping you complete projects better & faster.


There are various types of cardboard grooving machines on the market, how do you choose the most suitable type?


Read this guide to buy your dreamy cardboard grooving machine for rigid/gift box production or hard case making.



The cardboard V groove cutting machine is a standard piece of packaging equipment in the gift box industry, its blades remove excess fibers from the cardboard sheet surface along a path, forming V grooves.


With these V grooves, the cardboard is foldable to form a three-dimensional cardboard box.


Cardboard groover machines have similar functions to conventional creasing machines, but compared with the latter, it has the following advantages:

  • Sharp edges & corners, a simple & beautiful appearance after forming.
  • Rebound force reduction of the paperboard for anti-deformation.
  • Pre-folding process is unnecessary and post-gluing is more convenient.


A manual paper board grooving machine is suitable for manual grooving sample boxes, helping to develop innovative packaging designs, gift box prototypes, and rigid box samples.


Semi-auto cardboard V groove cutting machines are widespread in gift box & case proofing or small batch production.


An automatic cardboard grooving machine is useful for bulk rigid box or hardcover case making, such as luxury boxes, mobile phone boxes, wine boxes, tea boxes, shoe boxes, bookcases, etc.



There are 3 types of V grooving machines for cardboard:


Such an automatic grooving machine grooves cardboard & MDF sheets in batches.


It is essential equipment for the mass production of rigid boxes, gift boxes, hardcovers, and hard cases.


Working Principle

Before understanding how it works, let’s roughly digest its structure regarding the schematic below.


Such an automatic rigid box grooving machine consists of the following components:

  • Frame
  • Board Baffle (Magazine)
  • Infeed Belts
  • φ60cm Drum
  • Drum Belts
  • Cutter Blades
  • Outfeed Belts
  • Motor
  • Chain & Gear Drive
  • Leveling Feet

A worker manually adds board sheets to the baffle magazine first;


Then the infeed belts convey sheets to the surface of a φ60cm drum;


As the drum rotates, cardboard, KT board, or MDF sheets pass through diagonally opposed cutters;


These cutter blades remove excess fibers from the sheet surface;


Forming V grooves:



Such a rigid box grooving machine adopts an automatic correction combination (belt, anti-deflection wheel, board baffle magazine).

Thus you could directly place the sheets into the magazine and these sheets are automatically corrected before passing through the V-groove cutter, ensuring the accuracy & uniformity of grooving.


The groove blade holder introduces a unique structure design, ensuring:


  • No error in grooving;
  • Back and forth shaking of sheets is avoidable;
  • Blade holder & drum damage is avoidable during debugging.

And the blade position is adjustable via the knob.


There are visible scales under the knob, which is convenient enough.

Imported tungsten steel cutting blades ensure long grooving life & excellent grooving effect.


In addition, this machine automatically cleans waste materials after grooving and collects them, the recycled waste materials can pay part of your electricity bill after being sold.


Imported high-quality transmission bearings ensure extremely low noise & eccentricity when the machine operates at high speed.

Gear & chain drive replaces belt drive to improve machine quality and extend service life.

A semi-automatic V groove cutter machine is useful in prototyping gift boxes & rigid boxes, and some customers also use it for small-batch rigid box grooving.


Three types are available for your choice:

Pneumatic Control

Working Principle

First, let’s show you the following schematic.


Converting cardboard sheet to v-groove cardboard on this machine involves three steps:

  • Corner Cutting


  • Vertical Grooving


  • Horizontal Grooving



A 32mm diameter air cylinder controls the cutter stroke.


With high-precision slide rails, a high-pressure output rodless piston cylinder, and an aviation aluminum workbench, they ensure high grooving accuracy & good prototyping effect;


Its automation lies in corner cutting, cardboard sheet pressing, and V-groove cutting, the latter two motions must be completed artificially on the manual model.


The photo below displays its program control screen.


Parameters are adjustable on it, such as cutting time/stroke, and the control is convenient.

As the grooving angle needs to change in real production, its blade holder is user-friendly, with fast knife changeover & high stability, minimizing downtime.


The following features are also attractive among clients.


Furthermore, this cardboard groove cutter is capable of grooving 4mm thick MDF, the same thickness supported by Kolbus NM 101 of Germany:

Item Pneumatic Control Semi-auto Cardboard Grooving Machine

Air Pressure 0.5Mpa-0.8Mpa | 5-8 Bar

Servo Driven

A servo motor controls the back-and-forth circulation of the cutter, which is more precise, smooth, and stable.


  • Cutter circulation without air compressor, no more affection by air pressure;
  • Smoother blade back-and-forth movement, blade loss rate reduction;
  • Consistent groove depth without a difference;
  • Optional manual/automatic controls.

Its price is higher than the pneumatic control one.

If you have extremely high requirements for precision, stability, and smoothness, we recommend you choose the servo version;


As long as the pressure of your compressed air source is stable, the pneumatic control model can also meet your high-quality cardboard grooving requirements.

Servo Driven Automatic Size Adjustment

This is the latest model launched in 2024.


It also uses a servo to control the cutter blade circulation and adds a servo for automatically adjusting the grooving height.
