We cut high carbon steel, mild steel, stainless steel and aluminum up to 1" thick on a 2 axis table. Plasma cutting is the most affordable method to produce accurate, clean cuts. This style of cutting is great for all types of decorative and functional art, residential designs and industrial parts. Please supply us with either a .dxf file or a clear, detailed drawing with all appropriate measurements. Our 4’x8’ Tracker CNC table paired with a Hypertherm Powermax 85 plasma machine allows us to cut a wide range of parts. Items ranging from bucket ears on forklifts to finely detailed wall décor and decorative steel planter boxes are within our capabilities. We take the difficulty out of CNC cutting by drawing your parts for you. Simply supply dimensions and a sketch and we will take care of the CAD design and CNC programming. And if you already have a drawing, please send over a CAD file, .dxf, .dwg or .plt file. Common Items for Cutting • Metal art including: words and quotes, wall decals, decorative plaques, custom address number plates and signs, decorative railing and fence inserts, customized trivets and coasters. • Garden items: corten steel planter box, herb and vegetable garden stakes, hanging planter brackets and hangers, custom backyard fire pit grates, stainless steel BBQ grills, family name signs, rusted steel silhouettes and/or words and sayings, metal light boxes. • Interior Design pieces: steel coffee tables, end tables, stainless steel backsplashes and counter tops, light fixtures, fireplace screens, custom ceiling fan and chandelier plates, metal wall art, company signs, window security bars, decorative doors, customized table tops. • Custom brackets, gussets and flanges for automotive and industrial applications such as: forklifts, excavators, steam rollers, dump trucks, snow plows, tractor/trailer, car trailers, tow trucks, delivery trucks and more. • Customized truck and 4x4 grill inserts, diamond plate parts • Heavy machinery replacement parts • Industrial equipment repairs Cutting Information There is often confusion about the difference between plasma cutting, water jet cutting and laser cutting. Plasma cutting is designed specifically for cutting metal, whereas water jet and laser can cut a number of different materials. The way a plasma cutter works is by forcing compressed gas (oxygen in this case) through a nozzle where an electrode emits an arc. The arc travels to the surface of the metal being cut while turning some of the gas into plasma. The plasma is so hot it melts the metal, and the pressurized gas forces the molten metal through the cut and away from the bottom surface. The advantages and drawbacks of these different cutting methods are this: Plasma Cutting This is the most affordable cutting method while still delivering great speed and accuracy. It cuts mild steel, stainless steel, hardened steel, aluminum and various other metals. The main drawback of plasma cutting is edge squareness, although with a properly tuned machine this is very miniscule (between 1 – 3 degrees) and doesn’t pose a problem for most applications. Water Jet Cutting The advantages of a water jet system are its ability to cut incredibly thick material (upwards of 12” in aluminum), and it’s edge squarness. This can be useful for heavy-duty machinery and other parts where very tight tolerances are required. The drawbacks of this cutting style are that it is quite costly, and notably slower than plasma. Laser Cutting Laser cutting is the most impressive-sounding of the three, and it deserves it. With the ability to cut extremely intricate pieces with incredible accuracy, laser cutting delivers something neither water jet nor plasma can. Laser cutters can have positioning accuracy of 10 micrometers and can have cutting tolerances down to 0.001” (0.025 mm). The drawbacks are that it can’t cut very thick material, and it is very expensive.
