Vorrichtungs- und Vorrichtungsbau: Die entscheidenden Unterschiede verstehen

What is a Jig?

A jig is a type of tooling used in manufacturing to control the location and/or motion of another tool. Jigs are essentially guides; their primary function is to guide the cutting tool, such as a bohren, directly to its target on the Werkstück. A common type of jig ist die drill jig, which guides a bohren bit for creating holes in precise locations. A jig might be equipped with a bushing to provide a hardened surface through which the bohren can pass, ensuring accuracy and extending the life of the jig.

Wenn wir über jigs, we often consider their role in improving repeatability. For instance, in a scenario where a worker needs to drill holes in the same position on numerous pieces, a jig ensures that each hole is in the exact same spot on each Werkstück. As a leading CNC-Fertigungsdienstleistungen provider, we understand that jigs can also reduce human error. By using a jig, the chances of a bohren slipping or being misaligned are greatly reduced. Jigs are made to guide the cutting tool and not to hold the workpiece in place without the help of clamps or other securing mechanisms. Some common types of jigs einschließen. plate jig und box jig.

What is a Fixture?

A fixture is another type of tooling used to securely locate and hold a Werkstück during a Herstellungsverfahren. Anders als jigs, fixtures do not guide the cutting tool. Instead, fixtures are designed to hold the Werkstück steady and in the correct position relative to the Maschine or cutting tool. This might include fräsen cutters, Schleifen wheels, or tools for drilling and tapping. Think of a fixture as a secure base that holds the Werkstück while the machining tool remains in place. This can improve Fertigungsqualität.

Fixtures are essential when the operation requires maintaining a precise relationship between the Werkstück and the cutting tool, but the tool itself does not need guidance. For example, fixtures werden verwendet für fräsen operations where the Werkstück must be held firmly while a Mühle cutter shapes it. Fixtures are made to be robust and often involve clamps and other securing mechanisms to ensure the Werkstück remains stationary. They are very important for Bearbeitungsvorgänge and increase interchangeability. I am proud to say that we, at our company, employ advanced fixture design principles to ensure the highest accuracy in our processes, such as CNC-Bearbeitung.

What are the Key Differences Between Jigs and Fixtures?
