How Can Water Jet Cutting Machine Cut Through Steel?

Water jet cutting machines are pieces of modern cutting equipment that are ubiquitous in machining shops, not just in the country, but in many different parts of the globe, too. As the name of this tool suggests, it harnesses the “gentle” power of water to cut through tough objects like metal.

Given the right conditions, a high-pressure stream of water can easily cut through the toughest material known to man. And as earlier stated even the toughness of metal is no match to high-pressure water.

The secret to cutting tough objects like metal with the use of water lies in how we keep the sprayed water coherent. Water jet cutting machine can cut through object by making a steady, pressurized stream of water pass through an extremely narrow jeweled nozzle. By this measure, the sprayed water will remain strong and coherent.

Unlike traditional material cutting methods that we are most familiar with, this modern method of cutting metal will never get dull and since it does not generate heat, there is no risk of overheating. 

With the use of a mechanical method of cutting, you can only work on just a single piece of metal. You can only cut one metal at a time, which is highly disadvantageous because it is time-intensive and can be very expensive, too. 

Waterjet cutters are computer-controlled, and to further intensify their cutting power abrasive materials can be added to pressurized water. 

Abrasive-Mixed water leaving the nozzle comes at an amazing speed of 900 mph. The latest and most recent models of water jet cutters can cut within two-thousandths of an inch. A typical example of materials that can be cut through waterjet machines include: 

  • Wood
  • Stainless steel
  • Granite
  • Metal
  • Plastic
  • Stone
  • Marble

Water jet cutting machines are capable of cutting through a “sandwich” of different kinds of materials to a maximum width of 4 inches thick. The whole cutting process is itself can be considered as relatively “clean” in the sense that it is odorless, no foul-smelling fumes generated, dust-free and heat-free process. It can even if your material is as thin as 5-thousandths of an inch.

The tiny stream of water is so refined that the first run of cutting can easily qualify as the final finished surface due to its unparalleled quality and seamless edging. This single cutting process is a highlighted feature of waterjet machines because it can significantly help you save good money on material and machining costs.

For instance, if you are working as an engineer, you can partner with a reputable machining shop. You can submit to them your gear drawing image via email and it will be sent back to you soon after the waterjet machining is done and complete.

Standard waterjet machines are capable of cutting through “softer” materials. In the case of abrasive waterjets, you can utilize their cutting power for “harder, tougher” materials which include metals. The actual waterjet cutting process is often carried out underwater. This will help minimize the generation of noise and the splash of water. By employing the use of faster feed rates, the machine can be kept from cutting your object or material all the way through.
