Stainless steel tube for medical burr
Cutter head (cutting part): Made from 455 stainless steel, the hardness and wear resistance of which are significantly superior to conventional medical steel, resulting in highly efficient cutting.
Cutter rod:
1.Requirements: Medical stainless steel must have excellent corrosion resistance, good tensile ductility (for ease of laser welding) and sufficient rigidity.
2.Outer tube: With a closed front end and a sharp outer cutting edge, it performs a protective function.
3.Inner tube: With an internal cutting edge, it rotates at high speed, forming a cutting zone with the outer edge.
Medical equipment:
1.Application scenarios: Surgical instruments (staplers, ultrasonic scalpels), diagnostic equipment (endoscopes), interventional therapy (catheters) and other key medical supplies and equipment.
2.Standards and requirements: It is necessary to simultaneously satisfy the requirements of biocompatibility, micron processing precision, high cleanliness of the production environment, as well as corrosion resistance to the effects of physiological body fluids.
3.Key advantages and solutions of Xinliang: Based on many years of experience in deep long-term cooperation with renowned medical enterprises, we deeply understand clinical needs and offer highly reliable customized production solutions that comply with the GMP standard.

Product range
We can produce various types of stainless steel tubes with outer diameter from 0.4mm to 16.0mm and wall thickness from 0.05mm to 1.2mm. We have a significant advantage in the production of small diameter tubes and thin-walled tubes, which allows us to fully meet the stringent requirements of the precision manufacturing industry.
