Point Styles For Metal Tubing

Precision Tip Grinding for Cannulas, Needles & Stylets Component Supply provides precision tip grinding services for cannulas, needles, stylets, and specialty tubing components used in medical device, laboratory, and industrial applications. Our tip grinding capabilities allow engineers to create custom point geometries and specialized distal or proximal end configurations designed to meet specific penetration, access, flow, and performance requirements. Component Supply manufactures precision ground tips for a wide range of stainless steel and specialty metal tubing components, supporting both prototype development and production-scale manufacturing. Value-added grinding processes can be applied to either the distal or proximal end depending on the intended application, assembly requirements, and device functionality. Available tip geometries include:

• Bevel points
• Back bevels
• Lancet points
• Trocar points
• Franseen tips
• Pencil points
• Chamfer tips
• Deflected points
• Multi-facet grinds
• Custom point geometries

Tip grinding is commonly used in:

• Needle manufacturing
• Cannula fabrication
• Stylet production
• Catheter access systems
• Tissue penetration applications
• Septum penetration systems
• Biopsy and aspiration devices
• Minimally invasive surgical instruments

Component Supply works closely with engineers to determine the appropriate tip style, grind angle, edge condition, and geometry based on penetration force requirements, tissue interaction, fluid flow characteristics, coring reduction, manufacturability, and overall device performance. Precision tip grinding can support:

• Improved penetration performance
• Reduced insertion force
• Controlled tissue interaction
• Septum coring reduction
• Enhanced fluid flow
• Tight-tolerance tip geometry
• Repeatable point consistency
• Miniature and thin-wall tubing applications

Following tip grinding, components can be further customized through cutting, bending, EDM machining, laser welding, passivation, coating coordination, and additional secondary fabrication services to support complete prototype and production-ready assemblies. Component Supply supports tip grinding for:

• 304 stainless steel tubing
• 316 stainless steel tubing
• Hypodermic tubing
• Stylet wire assemblies
• Specialty metal cannulas
• Additional application-specific materials upon request
