Abrasive Waterjet Cutting is essentially an accelerated erosion process. Ultra-high pressure water created by a pump is fired through a ruby or diamond orifice into a "mixing chamber" which creates a vacuum and draws garnet into the water stream. This gives waterjet cutting flexibility that no other cutting process can offer. Irregular shapes can be cut from almost any material with exceptional precision and edge quality. Curves, straight cuts, internal holes and lettering once cut by hand can now be cut in a fraction of the time.
Quick Setup and Fast Turnaround
Our abrasive waterjet machining center uses your existing CAD files to create our tooling programs. Working from your drawings means you can say goodbye to elaborate CNC programs and waiting for dies or fixtures. No tool changes are required as we simply adjust the feed rate to the appropriate speed to match the material type and thickness.
No Heat Affected Zones
Any cutting process which generates heat has the secondary effect of changing the molecular structure of the metal in the affected zone. Waterjet is a cold cutting process which eliminates problems caused by heat distortion and hardened edges. The absence of HAZ means we can cut without warping or hardening materials, generating poisonous fumes, as well as cut parts that have already been heat treated.
High Accuracy and Smooth Cuts
Waterjet cuts are accurate within ±.005" for most applications and can create distortion-free parts of many complex shapes, which is a difficult achievement in stamping or die cutting. Edge quality is one of the most important reasons why designers specify waterjet for a smooth uniform finish. In many cases, waterjet eliminates the need for secondary finishing, thus creating significant time savings and improving efficiency.
Waterjet cutting is classed as a green technology as it only uses natural resources such as water and garnet (sand). Waterjet requires no cooling or lubricating oils and does not generate noxious fumes during the cutting process unlike thermal processes such as laser or plasma. We recycle all spent abrasive and waste material to keep the environmental impact relatively low.
Kerf refers to the amount of material that is removed during cutting. The width of the waterjet cutting stream is .03" and produces a smaller amount of kerf compared to traditional cutting tools. Aerospace and military aviation are two key industries that require high precision waterjet cutting with minimal kerf to cut expensive materials such as titanium, aluminum, nickel alloys, and Kevlar.
Range of Materials
The diversity of materials that can be cut with the waterjet makes it one of the most attractive capabilities of this technology. Waterjet cutting processes can cut different materials based on strength, durability, corrosion resistance, and conductivity. Specialized techniques such as low pressure piercing can help cut natural materials such as stone, glass, and ceramics.
