An example of a jig is when a key is duplicated; the original is used as a jig so the new key can have the same path as the old one. Since the advent of automation and computer numerical controlled (CNC) machines, jigs are often not required because the tool path is digitally programmed and stored in memory. Jigs may be made for reforming plastics.
Concealed hinge drilling jig with embedded Forstner bit. A concealed hinge drilling jig is a type of support jig, designed for drilling 3 cm holes to fit concealed hinges into modern wardrobe doors. As many of the complementary tools used in woodworking, it uses an electric hand-drill for its operation, making a Forstner bit to turn.
Wheel drawer slide A wheel drawer or roller runner slide (sometimes called a European-style slide) is a simple mechanism that can handle heavy loads. However, the drawer cannot be fully extended, except when removing it. Ball bearing slides Ball bearing or steel ball slides have ball bearings to make drawers slide more smoothly. Telescoping ...
A pocket hole jig is generally made of plastic and has a metal insert that the drill bit is inserted through to drill the hole. A jig can be a stationary device that the wooden pieces are clamped into, or a portable device that is clamped onto the wooden pieces. [3]
A common type of fixture, used in materials tensile testing (Grip-Engineering). A fixture is a work-holding or support device used in the manufacturing industry. [1] [2] Fixtures are used to securely locate (position in a specific location or orientation) and support the work, ensuring that all parts produced using the fixture will maintain conformity and interchangeability.
A jig grinder is a machine tool used for grinding complex shapes and holes where the highest degrees of accuracy and finish are required. The jig grinder is very similar to a jig borer , in that the table positioning and spindles are very accurate (far more so than a manual milling machine or lathe ).
The jig borer was a logical extension of manual machine tool technology that began to incorporate some then-novel concepts that would become routine with NC and CNC control, such as: coordinate dimensioning (dimensioning of all locations on the part from a single reference point);
Hardened and ground plug gauge Replaceable thread and plug gauges. These gauges are referred to as plug gauges; they are used in the manner of a plug.They are generally assembled from standard parts, where the gauge portion is interchangeable with other gauge pieces (obtained from a set of pin type gauge blocks) and a body that uses the collet principle to hold the gauges firmly.
