INTRICATE AND PRECISE, CNC LASER TUBE CUTTING FOR MEDICAL DEVICE COMPONENTS
For medical device components and implantables, our CNC laser tube cutting machines are capable of holding extremely tight tolerances. CNC laser tube cutting is highly repeatable and suited for medium to high volume quantities.
CNC 2 + 2-AXIS LASER TUBE CUTTING FOR MEDICAL DEVICE COMPONENTS
Many of Marshall’s customers have extremely tight tolerance requirements on their medical tube components. We offer unique capabilities within our CNC 2 + 2 axis laser tube cutting technology for medical device components. 2 axis are used to rotate the tube and axially move the tube, and 2 additional axis can be programmed to move side to side, and up and down. CNC laser tube cutting is highly effective when manufacturing moderate to high quantity production runs.
Fine-tuned for the medical and biomedical device communities we serve, CNC laser tube cutting is a fast, precise, highly-repeatable, extremely reliable and a strong force supporting Marshall’s medical device contract manufacturing services.
One of the primary benefits of using the laser cutting process is a minimal “heat affected zone” (HAZ). The heat affected zone is the area of the tube which doesn’t melt, but is affected by the heat of the laser, which alters the microstructure and mechanical properties of the tube. The heat affected zone is minimal when considering the very small beam-width, the thin wall of the hypo tube, the feed rate of the material and the water-cooled tube.
Marshall can accommodate tube diameters ranging from .5 mm to 8 mm (.020″ to .315″). Maximum wall thickness is approximately .5 mm (.020″) with most materials. At Marshall, our laser tube cutting machines can generally hold tolerances of +/- .013 mm (+/- .0005″).
Many medical device components that begin their process in our CNC laser tube cutting cell proceed to a secondary operation, such as a CNC laser welding process. In the welding process, the laser cut tube can be assembled to another tube or component. In many cases, CNC laser welding is the preferred method of assembly because no new material is introduced into the process.
CNC 3D bending of finished laser cut tubing is also a proficiency of Marshall. It’s common for us to bend a laser cut tube component in both 2 dimensional and 3 dimensional configurations – often orienting off of a laser cut feature – resulting in that feature landing consistently in place within the 3D bent component.
Marshall offers 4-Axis CNC Laser Tube Cutting. As a medical device manufacturer, our machines can produce highly intricate tube components.
2+2 Axis Diagram: When the Y-Axis is utilized during the cutting process (and the tube is not rotated), the cut edges remain parallel thoughout the cut.
3 Axis Cutting: When the tube is turned during the cutting process (and the Y axis is stationary), the outer cut edges are at an angle from each other.
