Which CNC Profile Plate Cutter?
A CNC profile cutter is a metal plate cutting machine that utilises plasma and or oxy-fuel cutting technology to cut through metal.
For years Messer Cutting Systems, ESAB, BOC, Koike, Esprit, Kerf, Farley, ACS, Hypertherm and SAF have been providing cutting edge technology for the metalworking industry worldwide.
Allowing both straight and bevel oxyfuel and plasma cutting to ensure the quality, reliability, and savings to the cutting process.
Which process you need will depend on the material being cut.

A OPTIONAL ECONOMICAL PROCESS
Oxyfuel flame cutting is the most economical process for the cutting of mild and low alloy steel, even with weld preparations. It is one of the most important production processes in the metal industry.
THE PROCESS OF OXYFUEL PLATE CUTTING
Oxyfuel or flame cutting is a combustion process using oxygen/fuel gas flame. The heating flame brings the material up to its ignition temperature. Then a jet of oxygen at least 99.5% pure is blown onto the heated spot. The oxygen jet oxidizes the metal then the torch is moved and a narrow cutting kerf is created, removing the slag from the kerf. The quality of the cut depends on the surface condition of the material, cut-velocity, and thickness.
All low alloy steel with a material thickness up to several inches can be cut with this process. Despite the increasing significance of the other cutting processes such as Plasma and Laser cutting, Oxyfuel flame cutting is still a very economical process. For heavy material thicknesses up to 35 inch (900mm) there is no alternative to Oxyfuel flame cutting.
Oxyfuel cutting ensures reliable hole-piercing, high cut quality which the production of components to their finished sizes without the need for further processing. For weld seam preparations V, Y, and K cuts can be produced.
OXYFUEL CUTTING CHARACTERISTICS
Plate thickness: 1/8 inch (3 mm) up to 35 inch (900 mm)
Typical: 3/8 inch (10 mm) up to 12 inch (300 mm)
KEY FEATURES OF OXYFUEL PLATE CUTTING
Good cut quality
Smooth, vertical planes of cut
Metallurgical perfect surfaces (oxidized)
Carbonizing and hardening within the area of the heat affected zone
High heat input
Wide range of material
Low cutting speed
FAST, ACCURATE AND HIGH QUALITY
Plasma cutting was originally developed for the thermal cutting of materials which were unsuitable for flame cutting, such as high alloy steels or Aluminum. Today, the process is also used for the economical cutting of thin, low alloyed steels.
WHAT IS PLASMA? THE FOURTH STATE OF MATTER
One common definition of plasma is to describe it as the fourth state of matter. We normally think of the three states of matter as solid, liquid, and gas. For a common element, water, these three states are ice, water, and steam. The difference between these states relates to their energy levels. When we add energy in the form of heat to ice, the ice melts and forms water. When we add more energy, into the water it vaporizes into hydrogen and oxygen, in the form of steam. By adding more energy to steam these gases become ionized. This ionization process causes the gas to become electrically conductive. This electrically conductive, ionized gas is called a plasma.
HOW PLASMA CUTS THROUGH METAL
The plasma cutting process, as used in the cutting of electrically conductive metals, utilizes this electrically conductive gas to transfer energy from an electrical power source through a plasma cutter torch to the material being cut.
The basic plasma arc cutting system consists of a power supply, an arc starting circuit and a torch. These system components provide the electrical energy, ionization capability, and process control that is necessary to produce high quality, highly productive cuts on a variety of different materials.
The power supply is a constant current DC power source. The open circuit voltage is typically in the range of 240 to 400 VDC. The output current (amperage) of the power supply determines the speed and cut thickness capability of the system. The main function of the power supply is to provide the correct energy to maintain the plasma arc after ionization.
The arc starting circuit is a high frequency generator circuit that produces an AC voltage of 5,000 to 10,000 volts at approximately two megahertz. This voltage is used to create a high intensity arc inside the torch to ionize the gas, thereby producing the plasma.
The Torch serves as the holder for the consumables especially nozzle and electrode, and provides cooling (either gas or water) to these parts. The nozzle and electrode constrict and maintain the plasma jet.

Still not sure which profile cutting process would suit? Why not combine both flame and plasma on one machine?
We have over 50 years experience of suppliying around the world Gas and Plasma cutting machinery often bespoke to suit the client's budget and requirements.
The majority of plate cutting machines we sell are refurbished to order, the width cannot be altered however the length of track can be altered to suit, the number of torches, CNC units and software can all be added. These machines are in stock today and take a maximum of 3 weeks to refurbished fully and re-spray.
