What to Consider Before Buying an Abrasive Water Jet Cutting Machine?

Waterjet cutting technology uses abrasive particles, such as garnet, added to a high-pressure water stream to effectively cut hard materials. The abrasive particles are inserted into the nozzle of the Water Jet machine.

WaterJet Cutting Machine is in operating mode, the abrasive particles cut the material, and the water acts to accelerate the particles suitable for cutting. As the water pressure increases, the cutting efficiency increases.

Abrasive water jet cutting machines are best suited for cutting a variety of thick and rigid materials, such as plastics, stone, and metal. It is easy to set up, the fixture can be assembled in minutes, and no professional training is required to operate the machine.

With an abrasive water jet cutting machine, you can get fast cutting, higher productivity, and high-quality parts.

So how to choose the right abrasive water jet cutting machine?

1. What grit size do you need when you buy the waterjet cutting machine?

First, to find the correct grit size when searching for an Abrasive Waterjet machine.

For precise cutting, choose smaller abrasives, while large abrasives ensure productivity but the cut will be much rougher. Small grits are priced higher than large grits.

If you wish to eliminate the need for secondary finishing procedures, then choosing the right size grit is essential. Smaller grits produce a finer, cleaner surface than larger grits.

In short, a beautiful polished surface requires a smaller grit size.

2. Is a taper compensation head required?

Taper compensation is undoubtedly a misnomer. But does it work? If you tilt the jet before it penetrates the material, the answer is yes. The slight taper of the waterjet machine edge is transferred to the scrap material, producing a straight edge on the part surface.

Taper compensation is undoubtedly a misnomer. But does it work? If you tilt the jet before it penetrates the material, the answer is yes. The slight taper of the waterjet machine edge is transferred to the scrap material, producing a straight edge on the part surface.

For taper compensation to work, the material needs to be perfectly flat. In addition, you need a cutting head that allows for tilting motion, rotation, lifting, or what is commonly called a taper compensating head.

However, taper compensating heads can be damaged by operator negligence or material tilting, resulting in costly downtime and high repair bills.

If your workflow often requires straight product edges, choose a waterjet machine with a taper compensating head. Otherwise, it does not make sense.

3.Is an UHP pump system worth it?

Over the past 20 years, our Kunda has made significant advances in waterjet technology. Driven by new materials and mechanical engineering upgrades, we now have pressure pump systems that exceed the 100KPSI mark.

While these UHP pumps increase cutting speeds, they do come with a high price tag:

· High-pressure pumps cost 20-50% more than conventional pumps.

· The components required to deliver the high pressure through the pump must be high quality, which means increased upfront costs.

· The maintenance involved is more frequent as machine parts wear out from the UHP water.

In practical applications, a manageable level for UHP pumps is between 60 and 70k to prevent premature damage to other machine parts and extend 1-11024-High-Pressure-Waterjet-Parts-In-Stock-For-Sale-p.html target='_blank'>Seal life.

4. Is water recycling required?

You can add a water recycling system to your waterjet cutting machine to prevent water waste, but it costs $7-9 per hour. The water recycling system includes pumps, water tanks, DI resin containers, graded filtration, and chillers, all of which require extensive maintenance to ensure optimal performance.
