Title: Clamping of Sensitive Parts
1Clamping of Sensitive Parts
Position-flexible clamping elements
for sensitive areas of workpieces
2Position-flexible Clamping Elements forsensitive
areas of workpieces
- Definition
- Position-flexible clamping devices are used
for supporting and clamping unstable workpieces.
They adapt to the position of the workpiece,
without deforming it. They prevent vibration and
clamp against working forces from all directions.
3Position-flexible Clamping Elements forsensitive
areas of workpieces
- Selection of Suitable Elements
- Position Flexible Clamp. Loading restricted
- Position Flexible Clamp. Loading Unrestricted!
4Position Flexible Clamp
- Advantages
- ? Comact 2 jaw element
- ? For Internal and external clamping
- ? Clamp Jaws easily adaptable
- ? Position flexible within the clamping range
- ? Adapts for large workpiece tolerances
- ? Lowest positioning forces on the workpiece
- (see important notes)
- ? Working forces allowed from all directions
- ? Double acting clamping function
- ? Seperate clamping operation
- ? Attachment on 4 sides possible
- ? Connection variants
- ? Slides lubricatible

8Position Flexible Clamp Technical data
Clamping force at 250 bar 7 kN Holding force
at 250 bar 4 kN Stroke, each jaw 6 mm
Important Notes The top of the position flexible
clamp must be examined occasionally for
contamination due to chips and cleaned if
necessary. Use similar stroke lengths if
possible Take CareA one sided position force of
10N can cause 2mm of stroke difference on the
workpiece.

Position flexible clamps
16Position Flexible Clamping Head
Advantages ? Large working range ? Bottom jaw
adjustable over 4 positions ? Unhindered loading
and unloading of the workpiece ? Lowest
positioning forces on the workpiece ? Zero-point
adjustable ? Working forces from all directions ?
Opening and clamping position signaled
electrically or pneumatically ? Access to narrow
pockets ? Double clamping function ? Clamping
connection separately controllable ? Connection
variants ? Protected hoses ? Purge air connection
to prevent entrance of chips and coolant
17Position Flexible Clamping Head Technical data
Clamping Force FSp at 250 bar 7,5 kN Holding
Force FH at 250 bar 10 kN Position Force
0 30 N Pendulum Range 4 mm
Important Notes Check regularly for contamination
due to chips and clean if neccesary. Lubricate
slides regularly to prevent positioning
problems The smaller the distance between
workpiece and woekpiece clamping point the
smaller the moving force on the workpiece when
positioning (see position force) Purge air
increases the lifespan of the element. The unit
is made from aluminium and should be protected
against abrasive chip accumulation.
