    Waterjet - Frequently Asked Questions

    What materials can the waterjet process cut?
    The waterjet can cut almost any metals, plastics, wood, tile, granites, and various other exotic materials. There are very few materials that the waterjet cannot cut.

    What are some advantages to waterjet cutting?
    The waterjet has a quick turnaround time for large work orders, and is an excellent choice for prototyping. The waterjet is faster than laser cutting for some thicker materials, and is able to cut reflective materials without surface preparation. We can finish most 2D machined parts complete (including tap drill holes), and with no secondary edge finishing required. Parts can be nested within a blank of material, increasing material utilization and reducing part cost. Parts can also be blanked out near net shape for edge finishing if required.

    What abrasive is used in waterjet cutting?
    The waterjet's pressure is usually around 60,000 PSI. Softer materials such as wood, paper, and cloth can be cut using only water. For cutting harder materials, such as metal, stone, and glass, small garnet particles are fed into the waterjet stream to make it an "abrasive waterjet."

    Do you do small jobs?
    Yes, we do. No job is too small. We create custom "hot rod" parts for car enthusiasts, and also handle "one-off" jobs, cutting single parts for individual customers. We do have a minimum charge on the waterjet machine, but you will be pleasantly surprised at the affordable cost of waterjet cutting for your individual part.

    What is the largest part you can cut?
    Our machine X travel 1000-2000mm, Y travel 2000-6000mm effective cutting bed. The largest actual part size we can put in our machine is 2000mm by 6000mm, and up to 2000lbs. In certain cases, we can cut larger parts.

    How thick of a part can you cut?
    We can cut from 0.2mm to about 100mm in height, depending on the material being cut.

    What is the normal inside corner radius from water jet?
    Our normal inside corner radius would be about 0.33mm with our standard nozzle. With our mini jet nozzle we can get down to about 0.25mm inside corner radius. This can change depending on part height.

    What kind of accuracy can you hold?
    Tolerances of +/-0.1 are common on smaller machine parts. In certain parts, we can hold tolerances of up to +/- 0.05. Again, tolerance is dependent on part height and surface finish required. Our WJ1020 is one of the most popular waterjets on the market.

    What type of CAD files do you prefer?
    We prefer .DXF files, but we can upload almost any type of CAD file to the waterjet.

    What is your normal lead time?
    Usually, we can get work out within 30 days (depending on prior commitments). If we have matched waterjet in stock, we can send within 1 week.
