Machine tools need to grasp the opportunity of energy saving and emission reduction
What is plasma cutting?
Plasma cutting uses a plasma torch to cut metals of various thicknesses. The plasma cutter blows compressed air out of a nozzle at high speed and at the same time forms an electrical arc between the nozzle and the metal to be cut. The resulting plasma is hot enough to melt the metal and the speed ensures that the molten metal is blown away from the cut.

In order to implement the national guidelines for energy conservation, material saving, and environmental protection, the machine tool industry has actively implemented green manufacturing to promote the harmonious development of people and the environment in development strategies and plans. Currently, the research work that the machine tool has carried out mainly includes: research on green design technology of machine tools, research on reconfigurable machine tools, research on life cycle development technology of machine tools, research on cleaner production technology of machine tool companies, research on and improvement of energy-saving technologies of numerical control machine tools Accuracy and performance of CNC machine tools, thereby improving the precision of parts blank machining, reducing the development of materials consumption research.
Adjust the structural change and development mode, eliminate backwardness, and suppress excess production capacity. To achieve the transformation from a manufacturing country to a manufacturing powerhouse, we must have a development strategy. Whether it is the development of the industry or the progress of the enterprise, it is necessary to formulate a strategic development plan, complete the task of structural adjustment and change the mode of development, and strive for sound and rapid development. Through the efforts of the entire industry, we have cultivated a group of large and powerful enterprises and a group of small and specialized small giant-type enterprises to improve the core competitiveness of the industry.
Intensify independent innovation and investment in scientific research.
Actively explore new ways of production, learning, research, and joint research. Technology and talents can be introduced into the development of the brain, and the development of medium and high-end products should be actively pursued. The focus of abrasives is the development of deep-processed products. Meet the needs of the rapidly growing photovoltaic industry and engineering ceramics and advanced refractories markets.
Promote green manufacturing. Green manufacturing refers to the modern manufacturing model that comprehensively considers environmental impact and resource efficiency under the premise of ensuring product functionality, quality, and cost. It is the development trend of the 21st century machinery manufacturing industry, and it is an important way to achieve a resource and energy efficient recycling application and minimize environmental impact, and establish a resource-saving and environment-friendly type.
Green manufacturing includes energy saving and emission reduction. This work is a prominent issue in the abrasive industry. Although the abrasive industry has not been included in the category of “two high and one capital†industry, the National Development and Reform Commission has explicitly included abrasive smelting. The limited industries have set the bottom line for the survival of enterprises. Enterprises must learn new technologies and new processes such as energy-saving and emission reduction, develop circular economy, and fully implement green manufacturing.

To properly explain how a plasma cutter works, we must begin by answering the basic question [What is plasma? In its simplest terms, plasma is the fourth state of matter. We commonly think of matter having three states: a solid, a liquid, and a gas. Matter changes from one state to the other through the introduction of energy, such as heat. For example, water will change from a solid (ice) to its liquid state when a certain amount of heat is applied. If the heat levels are increased, it will change again from a liquid to a gas (steam). Now, if the heat levels increase again, the gases that make up the steam will become ionized and electrically conductive, becoming plasma. A plasma cutter will use this electrically conductive gas to transfer energy from a power supply to any conductive material, resulting in a cleaner, faster cutting process than with oxyfuel.
The plasma arc formation begins when a gas such as oxygen, nitrogen, argon, or even shop air is forced through a small nozzle orifice inside the torch. An electric arc generated from the external power supply is then introduced to this high pressured gas flow, resulting in what is commonly referred to as a [plasma jet". The plasma jet immediately reaches temperatures up to 40,000° F, quickly piercing through the work piece and blowing away the molten material.
Plasma system components
Power supply -- The plasma power supply converts single or three phase AC line voltage into a smooth, constant DC voltage ranging from 200 to 400VDC. This DC voltage is responsible for maintaining the plasma arc throughout the cut. It also regulates the current output required based on the material type and thickness being processed.
Arc Starting Console – The ASC circuit produces an AC voltage of approximately 5,000 VAC at 2 MHz which produces the spark inside of the plasma torch to create the plasma arc.
Plasma torch – The function of the plasma torch is to provide proper alignment and cooling of the consumables. The main consumable parts required for plasma arc generation are the electrode, swirl ring, and nozzle. An additional shielding cap may be used to further improve cut quality, and all the parts are held together by inner and outer retaining caps.
