Waterjet Cutting

Jantz Canada offers both Water and laser cutting. They each have advantages and disadvantages and water jet cutting shines where laser cutting struggles.

Our Trumpf 2503 Laser can cut 1″ mild steel and 1/2″ stainless but it can be difficult to get a 100% clean cut on stainless plate. Another laser shortcoming is that it’s not ideal for aluminum and cutting small diameter holes in thicker mild steel is difficult due to the heat generated by the process. Waterjet cutting solves all of these issues and has other benefits that make it the perfect solution for many applications.

Waterjet can cut plastics, non ferrous materials and thicker traditional materials. While the laser has a maximum thickness of 5/8″ mild steel, the Flow Mach 2 water jet can cut material as thick as 6″. 

Understanding Waterjet

There are two types of waterjet cutting processes, pure and abrasive. 

Pure waterjet cutting is suitable for soft materials like gasket, foam, plastic, paper, disposable diapers, insulation, cement board, automotive interiors and carpet. The food industry even uses waterjet to cut meats and other organic food items due to speed and sanitary options.

The Abrasive waterjet process begins like pure waterjet but garnet abrasive is mixed with the water at the cutting head. The resulting abrasive waterjet stream is exponentially more powerful and can cut hard materials like metal, ceramic, stone, glass and composite.

How can water cut metal?

A water pump converts pressure into velocity via a tiny jewel orifice, creating a stream as small as a human hair

Introducing garnet into the supersonic waterjet stream increases cutting power by 1,000 times. Water and garnet exit the cutting head in access of the speed of sound.
