A guillotine cuts sheet in a straight line: the upper blade passes along the lower one at a slight angle and shears off a strip in one stroke. When the contour is straight and no holes are needed, it is the fastest and cheapest way to cut blanks. The catalog carries Turkish TRtech Procut shears, made by OSM Makina: 18 models in three cutting lengths — 3100, 4100 and 6100 mm — and six thickness classes, from 6 to 25 mm in mild steel.

Cutting length and thickness are two independent figures

Cutting length	Mild steel	Stainless steel	Power	Weight
3100 mm	6–25 mm	4–17 mm	11–45 kW	8–23 t
4100 mm	6–25 mm	4–17 mm	11–45 kW	10.5–30 t
6100 mm	6–25 mm	4–17 mm	22–45 kW	26–58 t

Length and thickness are chosen separately: a 6-metre machine comes both in a 6 mm and in a 25 mm version. Weight, however, grows steeply — from 8 t on the lightest Procut to 58 t on the heaviest — and that is a question of the floor, the foundation and the crane for installation.

All the TRtech Procut have a variable rake angle: the angle is set for the sheet thickness. The Spanish NARGESA C2006 CNC and C3006 CNC have a fixed 1.75° angle: 2030 and 3055 mm cutting length, steel up to 6 mm, stainless up to 4 mm, a 700 mm back gauge, 5.1 and 7.5 t.

What to compare

Thickness is quoted separately for mild and stainless steel. On the Procut the pairs are 6 and 4 mm, 10 and 6, 13 and 8, 16 and 10, 20 and 13, 25 and 17. Shears are rated by cutting force, and a stronger metal needs more of it, so the same machine takes less thickness in stainless.
Rake angle. The larger the angle between the blades, the less force the same sheet needs — but the more a narrow strip twists. On the Procut the angle is adjustable, from 0.3° to 2–3° depending on the model: thin sheet is cut at a small angle to keep it flat, thick sheet at a larger one.
Strokes per minute. On thin sheet it is 12–24 strokes, on 25 mm 4–6. If you cut many identical strips, this figure affects output more than the maximum thickness does.
Back gauge. The gauge travel is 1000 mm on the Procut and 700 mm on the NARGESA C CNC: that is the widest strip it can measure. Wider blanks are marked out or set against the front stops.
Hold-downs. Their number grows with the length: 16 on 3100 mm, 20 on 4100 mm and 29 on 6100 mm. They hold the sheet so that it is not dragged by the blade and the cut does not wander.
Control. All 18 Procut models come with a Cybelec Touch 8 CNC: strip sizes are entered on the touch screen and stored as a program, so a repeat order does not have to be set up again.

Guillotine or laser

A guillotine is cheaper to run: no gas, no optics and no source to pay for, and a strip is sheared in a single stroke. But it cuts only a straight line, leaves a small burr and twists narrow strips slightly. A laser machine cuts any contour with holes and without distortion, but it costs more and loses on speed in plain strip cutting. In many shops the two work together: the guillotine divides the sheet into blanks and the laser cuts parts out of them.

Common mistakes

Choosing a model by the maximum thickness without looking at the material: 25 mm is mild steel, and the same machine takes 17 mm in stainless.
Forgetting the weight: even mid-range models weigh 12–20 t and the heaviest 58 t, which calls for a suitable floor and crane.
Not checking the strip width: the back gauge measures up to 1000 mm and anything wider has to be marked out.
Costing the machine alone — without sheet feeding, run-out supports and scrap collection.

Send the material, thickness, sheet size and the number of cuts per shift — we will select the model, the rake angle and the handling system, and cost delivery, installation and training. After cutting, blanks are usually bent: how to choose a press is covered in “How to choose a press brake”, and the models are in the press brakes section. If the sheet has to be rolled into a shell, you need plate rolls.

Questions and answers

Why is the thickness lower for stainless steel?

Shears are rated for a given cutting force. Stainless steel is stronger than mild steel, so the same thickness needs more force and the maximum thickness comes out lower. On the Procut you can see it in the pairs: 10 and 6 mm, 16 and 10 mm, 25 and 17 mm.

How do I choose the rake angle?

A small angle means a flatter strip and less twist but more force; a large angle is the opposite. In practice thin sheet is cut closer to 0.3° and thick sheet at 2–3°. The angle on the Procut is adjustable, so it is set for each thickness.

Do you have mechanical guillotines?

The catalog has only hydraulic CNC shears. Hydraulics give a smooth stroke, an adjustable rake angle and overload protection, and the control stores cutting programs — more convenient for repeat work than a mechanical drive.

How much do guillotine shears cost?

The price depends on the cutting length, thickness, configuration and delivery terms, so it is not listed on the site. Send a request and we will prepare a quotation including delivery, installation and training.

What should I send for a selection?

The grade and thickness of the metal, the sheet size, the longest cut, the strip width, the number of cuts per shift and the floor area available. From this we select the model and the handling system.
