 Lasers truly destined for Precision with Packed in Creation
  Sahajanand technologies originate a compact and highly meticulousness amid fiber laser machine “SahajCut” for the Cutting of medical devices like Stent.  
  Stents look like a wicker mesh and are made of materials which consist of stainless steel, cobalt chrome and nitinol. These material it self present a unique challenges in fabrication to achieve the essential geometries. Fast Stent manufacturers usually take a tube 0.5 mm in diameter and take away 90 percent of it, leaving a very slender support structure. This involves comprehensive cutting that must be of the peak possible precision because of the significance of the end product.  
  Stent is an imperative Device in the Medical Industry as it works as Life Saver.  
  ' SahajCut ' is the achievement in Stent cutting technology for precise, speedy and dirt free cutting with solid structure. It required a nominal investment in tooling.  
  ' SahajCut ' provides archetype and production quantities with fast swivel and great results. Multi-axis CNC system with computer controlled is used to cut the parts, With the Cutting speed of 4 mm/sec (Linear) and 3mm/sec (Circular). No trouble for cutting a smallest possible radius due to use of fiber lasers in particular provide improved cut-surface quality due to the higher frequency of their pulses and motion control system for toning up the controlling speed of the beam motion and laser source.  
  ' SahajCut ' has been embedded with the technology to cut the 11mm thickness stent in less than 1.7 minute. With the Kerf width of less than 25 micron is achievable. With the optional 4-axis Stent cutting system for off center cut ‘SahajCut’ facilitate new Stent shape with ease.
