For medical device components and implantables, our CNC laser tube cutting machines are capable of holding extremely tight tolerances. CNC laser tube machining is highly repeatable and suited for medium to high volume quantities.


One of Marshall’s core capabilities is CNC Laser Tube Machining, for medical hypo-tube and other small tube machining applications. Laser tube cutting machines excel in producing intricate features such as holes and slots in thin-walled tubing to produce small surgical instruments and various devices and components with tight tolerances. Marshall has years of experience assisting customers with a host of tubing components and assemblies to match their unique product requirements.

Marshall’ laser tube machines 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″).

Marshall’s laser tube cutting machines offer 2 + 2 axis. Two axis rotate the tube and axially move the tube. The additional two axis can be programmed to move side to side, and up and down.

This video link (starting at 0:34 seconds to 00:52 seconds) demonstrates the laser tube cutting operation using only three of the four axis available. The laser remains stationary in the video, continually focused at the center of the part. The raw tube length is 3,660 mm (10 feet), and after the cutting process is completed, the finished part is severed from the initial tube. As each part is manufactured, the raw tube becomes shorter, until a new tube is loaded into the machine. The guide bushing is pictured immediately to the right of the laser beam, and the indexing collet system is on the far right of the picture.

In this example, the material diameter is 2 mm in diameter (.78”), and the finished part is approximately 11mm (.433”) in length. The wall thickness of the part is .10 mm (.004”). As you can see from the video, the tube has a multitude of cut features. Lasers can run wet or dry, and in the accompanying video, water is forced through the end of the tube. This prevents slag from building up on the through-cut-edges of the part—as well as eliminating slag on the wall opposite of the cut.

2+2 Axis Diagram:

When Y-Axis is utilized and the tube is not rotated, the laser beam cuts an off-center rectangle through the wall of a tube—and a vertical cut is produced on the longitudinal edge of the cut.

3 Axis Diagram:

When there isn’t an active Y-Axis and the tube is rotated—and the laser beam is directed towards the center of the part when cutting a rectangle through the wall of a tube—a bevel (trapezoid) is produced on the longitudinal edge of the cut.

What is Laser Tube Machining?

Laser tube cutting is a process in which a laser beam is focused on the outside surface of a metal tube to perform a cutting operation. The tube is fed in various patterns beneath the focused laser beam, where the tube wall is melted through. In medical applications with smaller tube diameters, the laser’s beam width is approximately .10 mm (.004”). Our machines are equipped with fiber lasers.

In the case of most laser machines, the laser is stationary and aimed directly toward the center of the tube. The tube that is being cut is fed through a stationary guide bushing—a “slip-fit” mechanism which stabilizes the tube while keeping it aligned and at a proper distance under the focused laser beam. Behind the guide bushing, the tube is held firmly by a programmable 360-degree indexing collet. This device can rotate the tube and has the ability to simultaneously push and pull the tube axially through the guide bushing. The CNC controller delivers the programmed instructions to these mechanisms, which cut out the desired shapes and configurations from the tube.
