Should reduce the manufacturing cost of cutting or reduce the processing cost of hardened u0026 rdquo; components. If the heat transferred to the workpiece during quenching is high, the stress formed by the previous cutting process will be released around the workpiece, causing deformation of the component. The workpiece needs to be left with a machining allowance, which requires a lot of material costs and has certain risks. As a result, subsequent processing must be performed on the hardened components, which consumes more time and expense. Our goal is to make the component in the 'soft' state, that is, to perform cutting and finishing before quenching, which requires a quenching process that produces little deformation. The use of HLDL laser for local quenching provides the best conditions for reducing quenching deformation. And can continue to maintain the basic toughness of the component core and correspondingly reduce the risk of cracks. A laser cutting machine can be recommended.   During laser hardening, the laser beam is aimed at the hardened part or part of the part, and only a small amount of heat is conducted to the component. Therefore, the component is not subject to large deformation, so that only a small amount of subsequent processing is required for the hardened workpiece or even no longer needs to be processed.   In addition, the higher energy efficiency and shorter process time of laser quenching play a positive role in the application of this quenching process. So that the hardened workpiece can be quickly used in the following production process. Laser hardening can be integrated into the continuous production process.  This quenching process is characterized by being environmentally friendly and clean. In addition, it opens up new possibilities for designers and production planners. For many years, it has been proved that laser quenching has obvious economic effects.  Industrial robots ensure the proximity of laser beams to components.   Use industrial robots to operate the laser light source of the HLDL laser. An attached swivel-tilt table for workpiece positioning almost completely ensures the proximity of the laser beam to the surface of the component. When needed, industrial robots can be supplemented with linear coordinate axes. The laser power controller Lompoe Pro ensures the best temperature stability of u0026plusmn;10oK on the surface of the workpiece. The temperature of the workpiece surface is measured with a camera and processed with a laser power controller. This can be achieved by accurately assigning temperature values u200bu200bwithin the quenching track. This satisfies the basic conditions necessary to achieve uniform hardening results under high-quality requirements.   Some other process parameters such as feed speed and different incident angles to the workpiece related to the geometric position are determined and evaluated based on many quenching processes and corresponding experiences. The mirror system (refers to the refractor and condenser in the laser system) can make the laser beam reach the surface to be quenched with the best projection angle in the internal range of the component.
