ESENTECH Non standard of Locating Pins by High precision cnc lathe turning for mould making

Introduction:

One of the most common ways of workholding is by location with reference to an external surface. This is also known as locating to a datum surface. Flat surfaces are commonly used for locating. However, there can be various types of locators depending on the application.

Locating Pin Method:

The most common method used for locating is with the help of locating pins. Locating pins are available in a variety of standard sizes and shapes depending on the application they are to be used in. For example a “diamond” head pin is used as a feature to help with the locating operation in situations with machining inaccuracies while a flat face with chamfered head style pin is used in applications with short strokes. The different kinds of pins available can be seen in the figure below.
