The jig saw concept first came about when an engineer attached a saw blade to his wife's sewing machine. Jig saws are used to cut out intricate patterns in the material you are shaping. If you need a curved edge or a circular cut out in the center of your material, a jig saw is the tool to do it. A jig saw blade moves in a rapid up and down motion to cut the material you are working with. The important thing to remember is that your body is softer than the material you are cutting and the blade will cut through you faster than the material. Be observant of where the blade is at all times and avoid cutting yourself. Bosch power tools were the first toolmakers to offer a jig saw to consumers. Bosch power tools are designed to aid in the workplace by being built to withstand the punishment professionals give their tools in the rush to finish work on time. Most are built to withstand a drop of ten feet and still work reliably afterwards. After vibration was noticed as detrimental to the physical health of workers, Bosch power tools set out to reduce vibration from their equipment. Bosch power tools has reduced the vibration by 60% over the years. Along with the low vibration, Bosch power tools are designed for low sound emissions as well. The fan motors are pitched to be less irritating and pointed away from the user as well so little noise directly impacts the worker. Handles and weight distribution are designed to make the tools comfortable to grip and use. Buttons and switches are conveniently placed to make the operation of Bosch power tools easier to do one handed. Bosch power tools even have left handed equipment available. Bosch power tools are ergonomically friendly, tough enough to withstand abusive treatment and quick to make adjustments to while working. This allows more production to be accomplished in a professional setting. This also makes them some of the most expensive available. There is an old saying that you get what you pay for. With Bosch power tools, this is definitely true. Engraving Tools and Engraving Machines Bob Jonathan Engraving is a process of incising a mark or design with an engraving tool onto a metal like zinc, copper, steel or non-metal like plastic. Gravers are conic tools (halved carbide round rod) with one cutting edge. The engraving equipments and tools like burin are pushed into the metal plate to produce cut and design of the marking. The deeper it penetrates into the metal, the wider the line becomes. The relationship between dipping depth and engraving width is determined by the top angle of the tool. Result may be a decorative mark or design in itself, as when silver or gold are engraved, or may provide an intaglio plate when copper is engraved or a relief print block when wood is engraved. Engraving tools are usually made with hard steel to cut the design into the surface like copper and steel plates. These tools come in a variety of shapes and sizes that yield different line types. Engraving tool produces a unique and recognizable quality of mark that is characterized by its steady, clean edges and deliberate appearance. Tools are manufactured in various shapes like angle tint tool, flat bottomed tool, flat gravers and round gravers. Each unique engraving marking tool has its own purpose. These durable engraving tools are useful for both wood, plastic and metal engraving. On request, we can also produce special designs on special engraving machines. Laser engraving is the practice of using lasers to engrave, etch, or mark an object. The technique can be very technical and complex, and often a computer system is used to drive the movements of the laser head. Despite this complexity, very precise and clean engravings can be achieved at a high rate. The technique does not involve tool bits which contact the engraving surface and wear out. This is considered an advantage over alternative engraving technologies where bit heads have to be replaced regularly. Engraving is a very specialised field. With so many types of material that can be engraved you need to be sure that the right method of engraving is selected for your product. http://www.ezinearticles.com/?Engraving-Tools-and-Engraving-Machines&id=54436 | ||||||||||||||||||||
