  • How much garnet abrasive does an abrasive waterjet use?

    Abrasive waterjets use approximately 0.5 pounds (0.25 Kg) of abrasive per  minute. Garnet abrasive is the most common abrasive used for abrasivejet cutting.  It is a  natural material that can usually be disposed of in a landfill.  Some abrasive suppliers  will take used garnet back for recycling.

  • How much maintenance is involved?

    As with any machine tool. waterjet systems require routine maintenance to ensure lasting performance. With a day or two of training, a waterjet operator of average skill level should be able to perform basic maintenance tasks such as replacing nozzle parts and pump seals. When selecting a waterjet manufacturer, make sure they offer lifetime water jet maintenance training.

  • How much training is required to learn how to run a waterjet system?

    An operator with no experience whatsoever should be able to learn how to operate and maintain a waterjet cutting machine with as little as about one week of training. .Companion software offered by Hypiont make it possible for an operator with no programming experience to program the machine with only a few hours of training.

  • Why is it better to cut under the water ?

    The underwater cutting allows to reduce the noise of the process under 75 dB but you can't see the process: by the optional automatic submerged cutting device it is easy to control and change the level in a few seconds in order to check the quality of the process.

  • What taper does waterjet cutting generate ?

    In a standard working process through a water jet cutting the taper depend by a cutting  speed; more speed more taper because the jet closed down on the thickness increasing the  taper from a minimum of 0, 1 mm (0,004”) up to 0,4 mm (0,016”) for each side of the cut;  this means that the bottom parts will be bigger respect the top one. By the H.T.C.  (Hypiont Tapering Control ? ) system is possibile to control the taper compensating by  a 4 axis inclination system

  • Why should we use to cut waterjet than the laster ?

    Laser is an high productive cutting system but water jet has many advantages over laser:
    No thickness limits
    No mechanics and heat change
    No material limits
    Maximum manufacturing and application flexibility (starting from rubber to titanium , from sponge to ceramic, from polystyrene to stone metal 60 Roc, from glass to stones, from  asket to the composites)
    No environmental problem (no smog and pollution) because is a clean technology that use  just ecological abrasive and water
    Low manufacturing process cost
    High performances
    Minimum hole diamater from 0.1 (0,004” water only) and 1 mm (0,040”) hydro-abrasive
    Accuracy from 0.05 – 0.15 mm. (0,002” – 0,006”)
    No holding devices request for many applications
    Multiple synchronized headsusage to increase production
    Easy maintenance directly on end user's site
    Relevant saving

  • What processes are waterjet cutting's competitors?

    There are other processes used for finely controlled material fabrication, but each has their own benefits and drawbacks. The processes that are superficially the most similar to waterjet cutting are laser cutting and wire EDM fabrication. Each of these processes are best at certain jobs, and are less adequate for others. It's up to the consumer to find out which cutting process has the best fit for their job.

  • How thick can my material be?

    Waterjet traditionally cut materials that are up to about 6-8 inches in thickness. Harder-to-cut materials might require a thinner profile.

  • Is waterjet cutting more expensive than conventional machining?

    Not at all. In fact, waterjet cutting provides efficiencies that in most cases provides a lower overall manufacturing cost.

  • Does waterjet cutting require a lengthy lead time?

    It depends on how much work needs to go into your design, but in general waterjet cutting is very fast and may be faster than conventional machining.

  • Does exposure to water or abrasives stain or warp materials?

    No more than normal exposure to water. Waterjet cutting does not cause unexpected damage.

  • Are there negative environmental impacts with water jet cutting?

    None at all. Water used in cutting is acceptable for standard drain disposal. Abrasives are organic in nature and separated and disposed of in a commercial dumpster. There are no hazardous materials used in waterjet cutting.

  • How does water jet cutting compare to conventional machining with regard to material waste?

    Water jet cutting allows for the maximum amount of parts to be cut from a single sheet of material. It’s as efficient as any other method.

  • What type of specific cut qualities are available and how are those determined?

    There are five distinct cut qualities that are generally used in waterjet cutting. These may be mixed and matched within one project depending on the needs:
    1: Used only when speed is of highest importance for very crude roughing out of parts. Lowest tolerance, highest speed. Rarely used.
    2: General purpose roughing out of parts. Used when tolerance takes a back seat to speed.
    3: Standard cutting quality. Good balance of edge quality and speed.
    4: Better surface finish and corner compensation than 3 at the sacrifice of speed.
    5: Reserved for special cases when edge quality and precision are more important than speed.

  • What material you can use waterjet or abrasive waterjet to cut ?

    Virtually anything! Here are a just a few examples of what you can cut with your Hypiont waterjet/abrasive waterjet cutting system.  Keep in mind that pure waterjet is used for cutting softer materials such as foam and rubber, while abrasive waterjet (abrasivejet) are used for cutting hard materials such as metals and stone. Literally anything non-toxic can be cut with a waterjet. Anything. This is only a broad  overview:
    Mild Steel
    Stainless Steel
    Tool Steel
    Aluminum
    Brass
    Bronze
    Alloys
    Wood
    Delrin
    Phenolics
    Laminates
    Cork
    Spring Steel

  • Is there any ways to increase waterjet cutting productivity?

    There are many ways to increase productivity with waterjet .You can add multiple cutting heads, you can buy an intensifier pump with higher pressure, you can stack materials and you can tightly nest parts to get more parts out of a sheet of material. The biggest gain in productivity in recent years has been the emergence of “hyper-pressure” waterjet intensifier pumps, such as Hypiont's  Edgestream 50  waterjet pumps. These pumps can double the cutting speed for some materials.
