SINE BAR CHUCKS

SBE-U

The sine bar chucks are used to set accurate angles ofworkpieces for highly precise grinding or as an inspection ﬁxture.
This is a type of chuck that utilizes angle setting by a sine bar
and the chuck work face can be set to a desired angle eﬃciently.
■Feature
The sine bar chucks come in various types such as electromagnetic, water-cooled, permanent electromagnetic, permanentmagnetic and in various sizes.

■Mechanism of Angle Setting by Sine Bar Chuck
A gauge block is used for setting the angle.

An angle is obtained by the trigonometric function using the gauge block dimension as thevertical side (a) and the roller center distance (from the center of open/close fulcrum shaft to thecenter of reference bar on the open/close side) as the hypotenuse (c), as shown.
aSinθ°＝ ̶̶c
Gauge block
Select an approximate value fromthe function table for θ°.
cWhen using a certain angle repeatedly,a method is available which uses a
special master gauge made to thea
dimension a, which determines anθ°
angle, obtained from the function tablein advance.
