Application of laser cutting machine for stainless steel instruments

(Click 77 )

Stainless steel instruments are widely used in medical, food machinery, industrial equipment and other fields due to their corrosion resistance and high strength. Traditional cutting processes are prone to material deformation, thickening of the oxide layer and other problems. Laser cutting technology provides efficient and clean solutions for the precision manufacturing of stainless steel instruments through non-contact processing and precise energy control, and promotes the industry to upgrade to intelligent and refined directions.

The core advantage of laser cutting machines lies in their micron-level precision and extremely small heat-affected zone (HAZ). Fiber lasers (wavelength 1064nm) melt materials instantly through high-density energy beams, and the incisions are smooth and burr-free, with a verticality of up to ±0.1°, which is especially suitable for processing stainless steel plates with a thickness of 0.1-6mm. In the manufacture of surgical instruments, laser cutting can process micro-hole arrays with a diameter of 0.3mm on 1mm thick 316L stainless steel, with an aperture error of ≤5μm, avoiding stress concentration caused by traditional stamping, and ensuring the mechanical properties and durability of surgical forceps, bone chisels and other instruments.

In the field of food processing equipment, laser cutting technology solves the health risks of traditional processes. For example, stainless steel impeller blades need to have both complex curved surfaces and surface finish (Ra<0.8μm). Laser processing does not require secondary polishing, and nitrogen-assisted cutting is used to inhibit the formation of oxide layers, which meets FDA food-grade contact standards.

The introduction of intelligent control systems further unleashes the potential of lasers. Visual positioning technology can automatically identify the position of stainless steel plates, dynamically adjust the cutting path, and increase material utilization by more than 25%; the digital twin system optimizes process parameters through virtual simulation, shortening the new product development cycle by 60%.
