What are Some of the Medical Applications for Waterjet Cutting Machines?

Applications and intended usage of waterjet cutting machines are growing by the day, and the medical sphere is one of those industries that has seen its great potential. For instance, the use of water jet cutting in medical parts can provide this industry the distinct level of precision that it so often requires, a value that is rare to find because there are no other material cutting methods we have today can come at par with that.

When it is all about custom cutting needs, tight tolerances, and meeting high standards of quality control on a wide range of alloys and metals, the use of commercial waterjet cutting methods in producing medical supplies will always remain up to such challenges.  

There are a handful of manufacturing firms in the country that cater to the production of various metal medical parts. They are more than capable of providing the industry with its required repeatable precision. 

In producing strong jets of high-pressure water, the waterjet cutting process can employ the use of hydraulic intensifier pumps. You have an option to meld here the use of garnet abrasive material — for maximum strength of 87, 000 psi.

With this, the cutting power of your waterjet cutting machine is further intensified and taken to its next level of precision. This time it has doubled its cutting power and can cut through aluminum, stainless steel, and steel. The following results can be enjoyed as its benefits: 

  • Cuts through with no involvement of heat which can have a bad impact on the cut itself as well as the integrity of the material around the cut area. 
  • Cutting process will not subject your material to cut stress
  • Complex cutting capabilities
  • Superior cutting power through thick and thin materials. 

With the implementation of the strictest standards and industry regulations applied to the fabrication of medical devices and equipment, you mustn’t leave behind the fact that custom medical equipment water jet cutting produces cuts that will not put the environment in harm’s way. They are usually free from imperfections and burrs that are normally brought about by material stresses.

Below are some of the waterjet cutting parameters being used by metal fabricating shops to provide the quality of service being required by the medical parts industry:

  • 78” x 156” table size
  • +/- 0.30 standard tolerances
  • 250 rms edge finish or better, processed at standard speeds of cutting
  • Eliminates taper
  • Metal alloys, as well as non-metal materials, can be cut through with the highest level of precision. 

The use of abrasive waterjet technology is more advantageous to the machining of medical components and devices than any other popular fabricating style. As one of the most versatile machining techniques around, this method is capable of handling virtually all materials, from macro to micro-scale. This also includes reflective and non-reflective metals as well as nonmetals like plastics, composites, and ceramics. 

As opposed to the laser machining method, the waterjet method is a qualified cold-cutting process which means to say that it will not generate heat in the surrounding areas being cut. There is the complete absence of a heat-affected zone or HAZ, that is.

A waterjet cutting machine can carry out an awful lot of processing functions, and this would include drilling, parting, cutting, grooving, milling, and surface preparation without the need to make use of special tooling much like how CNC machining does.  

You can also use water jets in net-shaping tools that produce precise parts, and they can be anywhere from difficult-to-machine materials, this includes stainless steel. For CNCs, it is natural for them to cut steel parts in their annealed state, where the processed parts will be heat treated until desired hardness for them is achieved.
