Engraving Equipment Technology from GravographGravograph offers a wide range of engraving equipment for your needs. If you are new to the engraving industry or looking to upgrade your existing equipment, consider the latest advancements from Gravograph-New Hermes. A Brief History of Engraving MachinesFrom the late 1930s into the late 1970s, manual (or pantograph) engraving equipment was the only type of engraving machine available on the market, thanks to the portable pantograph inventors and founding fathers of Gravograph. The first major application of the pantograph was engraving fountain pens for F.W. Woolworth Company. The second major application was for the New York City Board of Education during World War II, who needed plastic dog tags engraved for every child in New York City. After WWII, the pantographs were sold to jewelry stores across the country, engraving items such as pens, watches, lockets, etc. Click here to find out more about the history of Gravograph. Today, pantographs are still used in jewelry and specialty stores around the world. Rotary vs. Laser Engraving MachinesToday, there are two major types of engraving equipment now available: Rotary Engraving Machines and Laser Engraving Machines. The two main differences between the two types relates to the way the items are marked. Rotary Engraving EquiptmentRotary (or computerized) engraving equipment marks the items with cutting tools fixed in a spindle. The cutting tool either rotates (using carbide or diamond) to cut through or engrave the material, or with the spindle motor off using a diamond-drag tool, drags across the item to engrave the piece. Two machines offered by Gravograph that incorporate advancements in technology are the GravoTech M40 and GravoTech M40G Series of Machines. Both machines offer the highly acclaimed "point and shoot" technology developed to reduce set-up time and eliminate engraving errors. The "point and shoot" technology enables the user to size the engraving area via a laser spotting beam, which means no manual measuring is required. The laser beam also allows the user to trace out the engraving job, just to make sure that everything is in the right place. This helps when engraving unique or high-priced items. Both models also include an "Auto-Z" feature, which sets the Z-depth and cutter automatically. Again, Gravograph developed this feature to help the user reduce set-up time. Rotary Engraving Machines from
Gravograph Laser Engraving EquipmentLaser engraving equipment, unlike rotary, utilizes a CO2 laser power source, focused by mirrors and lenses, to mark the item to be engraved. Laser engravers can mark, engrave, or cut through most non-metallic surfaces. To mark on metal, a special chemical compound must be applied over the metal surface. (This compound is available for purchase from Gravograph.) Many user-friendly and time-saving features were incorporated into the LS range of equipment. First, Auto-Z was incorporated into the design to cut-down set-up time. Thanks to a special probe, the LS range can focus the laser beam automatically on the part to be engraved. Also the front-loading access to the working area was developed with ergonomics in mind. Click here to learn more about our laser engraving equipment.
