What is the fixture of the drilling machine?

Fixture of drilling machine is shorted for drilling machine die that is used to process holes and threads. The Fixture is mainly composed of drill bush, location device and clamping device, etc. Due to feeds less movement and the structural features, drilling machining tends to be lower precision, led to uncomfortably guarantee the accuracy of multi-holes drilling, so that, fixture of drilling machine plays a decisive role in drilling accuracy, and also fixture of drilling machine is the most widely used in all fixtures.

Structure of Drilling Jig
