With known kerf widths measuring between 20 and 30 µm, JK Lasers’ medium-power range, single-mode fiber lasers are designed for micro-cutting medical instruments, such as stents. According to the company, micro-cutting stents is a demanding manufacturing application, as tube diameters range between 1 and 10 mm and wall thickness measure 100 µm.
The lasers’ high beam quality and power stability are said to enable dross-free cuts with contour accuracy ranging to 5µm. This reduces the need for post-processing operations to achieve high-quality finishes, the company says.
The lasers deliver highly concentrated, controlled amounts of heat to reduce the heat-affected zone. Typical cutting speeds for medical stents with a single-mode laser output are around 1 m per minute, the company says.
