Oxy-fuel cutting is a chemical reaction between pure oxygen and steel to form iron oxide. It can be described as rapid, controlled rusting. HOW DOES OXY FUEL CUTTING WORK? Preheat flames are used to heat up the surface of the steel to approximately 1000�C (1800�F � bright red color) but below the metal's melting point. A jet of pure oxygen is then directed toward the heated area in a fine, high pressure stream. A vigorous exothermic chemical reaction takes place between the oxygen and metal forming an aluminum or iron oxide or rust. The pressure of the jet of oxygen blows away the slag or oxide forming a cavity. The preheat and oxygen stream are moved at constant speed to form a continuous cut.   WHICH ARE THE MAIN ELEMENTS OF OXY-FUEL CUTTING? The Main Terminology relevant to Oxy-Fuel Cutting is the following: Preheat Flame Oxygen Stream Torch and Cutting Nozzle Cutting Speed Material Being Cut CAN OXY-FUEL METHOD BE USED TO CUT ANY METAL? The answer is that it cannot! This depends on the melting point of the individual metals oxides. Only metals whose oxides have a lower melting point than the base metal itself (low carbon steel and some low alloys) can be cut with this process. Otherwise as soon as the metal oxidizes it terminates the oxidation by forming a protective layer. WHAT KINDS OF GASES ARE USED IN OXY-FUEL CUTTING? The Oxy-fuel gases used include oxygen, acetylene or liquefied petroleum gas (LPG); last two provide the high temperature Preheat flame.

Plasma cutting is a process that is used to cut steel and other metals of different thicknesses (or sometimes other materials) using a plasma torch. In this process, an inert gas (in some units, compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away from the cut. WHAT MUST A CNC BE EQUIPPED WITH TO BE ABLE TO CONTROL A HIGH DEFINITION PLASMA CUTTING PROCESS? Such a CNC should be similar to the ones controlling Laser Cutting processes. A modern CNC should have Response time less than 0.5 msec servo loop because it must be in a position to respond faster than the cutting process it controls. It should also have linear control over the current of the Source for it to be adjustable to the Feed Rate recommended.   WHAT IS HIGH DEFINITION PLASMA? High Definition Plasma is the same process as plasma cutting but the plasma beam is delivered through a much smaller nozzle orifice at higher velocity and results in more accurate profile cutting. A shield gas is also used to swirl around the plasma beam to constrict the beam and keep the cutting beam straight resulting in a square edge on the cut parts and better cut surface quality. WHAT IS PULSE PIERCING? The cutting energy is controlled by being delivered in high-and-low-current pulses, enabling the reduction of the volume of metal melted. This way we avoid risking molten metal spattering over the nozzle and sensors and destroying them. Pulse piercing is an important tell-tale trial for CNC suitability for High Definition Plasma cutting. WHAT MATERIALS CAN BE CUT ON A PLASMA CUTTER? Plasma Cutters are able to cut many conductive materials including Mild Steel, Aluminum, Copper and Stainless Steel. The most popular material cut in the industry is mild steel which also gives the best cutting results.

We could say that CNC is an electronic driver of the Cutting System based on the configurations by the user and the profiles of the parts to be worked on fed into the system before the beginning of the job. Making use of built-in electronic and software automation, CNC can control the cutting process calculating all available parameters, both the ones determined by the Cutting code (G-Code) fed into it beforehand and the real-time cutting data provided by the relevant sensors. It adjusts the proper gas mixture and velocity, the feed rate and the torch movement along the three axes, and the power of the Source. The cutting process is automatically continuously adjusted in the best way, much better than by the most experienced operator.   EQUIPMENTS INDIA SERIES MACHINE DELIVERS CNC cutting machines delivers full-featured and productivity at an affordable price. CNC Cutting machines by Equipments India is the best value in the industry.   WHAT IS CAM? Computer-aided manufacturing (CAM) is the use of computer software to control machine tools and related machinery in the manufacturing of work pieces. Traditionally, CAM has been considered as a numerical control (NC) programming tool, wherein two-dimensional (2-D) or three-dimensional (3-D) models of components generated in CAD software are used to generate G-code to drive computer numerically controlled (CNC) machine tools. The marriage of CAM software and control systems is critical to the successful implementation of any CNC machine.   HEAVY DUTY & FLEXIBLE DESIGN CNC cutting machine is high speed, high accuracy cutting machine which features compact modular construction of heavy-duty tubular structure for easy and fast installation.
