Single Acting Pull-Down Clamp, Concentric
Metric Special Use Clamps
- 5-sided machining can be carried out safely without clamp interference.
- Workpiece can be loaded and unloaded by handling equipment.
- Optional oil supply through G1/8 port or manifold connection.
- Disk spring for staged pull-down effect.
- Serrated grippers.
- Body, sleeves and draw bar are made of nitride-hardened alloy steel for longer trouble-free life.
- Clamping sleeves are segmented and serrated to form and grip the clamping hole.
- These Pull-Down Clamps also serve as a support surface and “Z” locator for the workpiece.
Maximum operating pressure 350 bar (35 MPa)
Minimum operating pressure 30 bar (3 MPa)
For proper sealing, the mating surface must be flat within 0.08 mm with a maximum surface roughness of 1.6 mµ Ra.
NOTE: For single acting clamping elements there is a risk of drawing in coolant during return stroke. In this case the clamping element has to be protected against the direct effect of coolant. The built in sinter metal breather should be covered.
