How to control the sheet metal tolerance,burrs,and scratches from laser cutting
The emergence of laser cutting technology has revolutionized sheet metal cutting. Understanding the nuances of laser cutting is critical when it comes to metal fabrication, as it’s an excellent way to make precise cuts in different materials. HY Metals is a company that specializes in sheet metal fabrication，laser cutting is the most important process, and we have a wide range of laser cutting machines in different power ranges. These machines are capable of cutting materials such as steel, aluminium, copper and stainless steel with a thickness ranging from 0.2mm-12mm.
One of the greatest advantages of laser cutting technology is its ability to make precise cuts. However, the process is not without its complications. A key aspect of laser cutting is controlling sheet metal tolerances, burrs and scratches. Understanding these aspects is critical to producing high-quality results.
1.Control cutting tolerances
Cutting tolerances are the differences in part dimensions that result from the cutting process. In laser cutting, cutting tolerances must be maintained to achieve the required precision. The cutting tolerance of HY Metals is ±0.1mm (standard ISO2768-M or better). With their expertise and state-of-the-art equipment, they achieve outstanding precision in all projects. However, the cutting tolerance of the final product is also affected by several factors such as metal thickness, material quality and part design.
2.Control burrs and sharp edges
Burrs and sharp edges are raised edges or small pieces of material that remain on the edge of a metal after it has been cut. They usually indicate poor cut quality and can cause damage to the final product. In the case of precision engineering, burrs can interfere with the function of the part. To avoid this, HY Metals uses laser cutting with a minimum focal spot diameter to prevent burrs from forming during the cutting process. Additionally, the machines feature a quick tool change feature that allows them to change focus lenses to accommodate different materials and thicknesses, further reducing the possibility of burrs.
Deburring process is also needed after cutting. HY Metals require workers deburr each part carefully after cutting.
3.Control scratches
Scratches during cutting are unavoidable and they can damage the final product. However, they can be minimized with proper control measures. One way is to make sure the metal is free from contamination and has a clean surface. We usually buy materials sheet with protection films on and keep the protection till the last fabrication step. Second, choosing the correct cutting technique for a particular material can also help minimize scratches. At HY Metals, they follow strict surface preparation, cleaning and storage guidelines to ensure the metal is free from contamination and employ the correct techniques to minimize scratches.
4.Safeguard
In addition to controlling cutting tolerances, burrs and scratches, additional protective measures can be taken to guarantee the high quality of the sheet metal. One of the measures HY metals takes is deburring. Deburring is the process of removing sharp edges from cut metal parts. HY Metals provides this service to their clients, ensuring that the final product is polished and of exceptional quality. Protective measures such as deburring ensure that the sheet metal can be used without hindrance.
In conclusion, controlling sheet metal cutting tolerances, burrs and scratches requires a combination of precision machinery, expertise and personal best practice. With more than ten laser cutting machines, experienced expert team and excellent industry knowledge, and first-class production facilities, HY Metals sets high standards in ensuring that the final products meet industry standards. Their experience and skills provide a reliable solution for anyone looking for the perfect sheet metal cut.
