Adjusting The Swivel Angle Using The Sine Principle - Sav 245.09 Operating Instructions Manual

Adjusting the swivel angle using the sine principle

Using the sine principle is the most accurate method of adjusting a variety of different angles. An uncomplicated
swivelling of the device allows precise adjustment in the angle/second range.
Before adjustment, release the transport lock and the clamping pincers and the bearing clamping on both sides and
hold on to the magnet. The front hexagon socket screw of the bearing blocks facing the machine operator are used
for the bearing clamping. The rear hexagon socket screws always have to be fully tightened.
Do not let the measuring rollers drop onto the gauge block support!
Larger sine tables are equipped with an adjustment gear unit. This is operated with a ratchet.
Be aware of the risk of crushing your fingers.
To ensure stability, always use two gauge blocks (only for sine tables longer than 350 mm).
Always clamp both bearings and pincers before machining.
For single-swivel sine tables (SAV 245.09 /.10), use the following equation to determine the gauge block
height H :
1
H = H
1
H : Gauge block to be used including H
1
H : Height of gauge block in zero position
01
A : Axis distance
1
α : Desired swivel angle
α : Angle of the zero position to the reference plane (base plate)
0
