Expanding mandrels are the
ideal solution to various internal clamping problems. Expanding mandrels
provide the benefits of versatility and accuracy when compared to other
workholding methods. The power operated, flange
type expanding mandrels can be used on any machine with drawbar
facility. The natural pull back action
of the sleeve ensures the component is resting
against the locating face. There is high clamping force due to the
clamping sleeve being in contact along its entire length through double
angle.
Expanding mandrels provide the following workholding features:
- Quick and secure clamping
- Positive location against backstops
- Controlled datums
- Uniform expansion
- Positioning accuracy
- Sleeve interchangeability - As sleeves in one type are interchangeable, one
single expanding mandrel covers a very large
clamping range.
- No pressure marks in the clamped bore. Easy
loading.
Expanding mandrels may be dedicated to one
component or a range of component types and sizes, locating in and
gripping component bores.
