Pantograph engravers were popular from the 1930s to 1970s, used for engraving jewelry, dog tags, and more. Different types include the B-Engraver for rings and the IM3 and TXL for various objects, all computer-controlled and adjustable.
A pantograph engraver is a machine used to engrave items such as jewelry, dog tags, electrical tags, and other specialty applications. It was a very popular engraving machine that was available between the 1930s and 1970s. One of the first large-scale applications of a pantograph engraver was engraving pens for a New York City company. It wasn’t until the 1940s, however, that the engraver was used extensively in engraving dog tags for military personnel during World War II. Also, during this same period, the New York City Board of Education had been distributing plastic dog tags, made by the same type of engraver, to schoolchildren.
There are several types of pantograph engravers available and they are used by businesses for many purposes. One type of pantograph engraver is called a B-Engraver and is used to engrave the inside of rings. It has several features, including the ability to automatically center a single ring via its clamping jigs and a diamond tool for easily engraving letters and other characters. The engraver is compact, economical and can also have an optional set of jaws to hold and engrave rings or stones of different sizes. This type of engraver is most commonly used to engrave wedding rings and their gemstones.
Another type of pantograph engraver is called the IM3, and is used for engraving nameplates, medals, badges and some small jewellery. One of the benefits of using this engraver is that oddly shaped objects can be pinned and engraved on the machine. An added benefit of this machine is that it has an arm that can rotate over a wider range, making it capable of handling large objects and engraving in places not normally reachable. This pantograph engraver is computer controlled and can be programmed to engrave certain letters and characters. The size of its engravings can be adjusted in 0.001 inch (0.0025 cm) increments.
A modified version of the IM3, the TXL is another type of pantograph engraver used to accommodate oddly shaped objects, especially cylindrical or flat-shaped objects such as bowls, cups and trophy plaques. This type of engraver is also computerized and can be programmed to engrave certain letters and characters, and can also be adjusted by the computerized component. The engraver is much larger, weighing up to 100 pounds (45.36 kg), and has a longer pivot arm for a greater reach and engraving range.
