Pneumatic centre-clamping vises

Pneumatic centre-clamping vises are mechanical centre clamps that are actuated by means of compressed air. Compressed air is supplied through two pressure lines that are connected to the centric vise. The compressed air ensures the automatic closing and opening of the centring clamp. The pneumatic actuation of the machine vise shortens the clamping process considerably. If the pneumatic centre-clamping vises is used with placement robots, the process can be completely automated.

Pneumatic centre-clamping vises are used in workpiece automation (large series) for blank clamping and precision clamping. Spreitzer offers various designs of pneumatic machine vises.

Compact, pneumatic centre-clamping vise with high centering and repetition accuracy as well high clamping force. Due to the pneumatic operation of this centre-clamping vise series the clamping process can be shortened or completely automated by the use of industrial robots. Strong Points Short clamping time, usable for automation High clamping accuracy Clamping width flexibly adjustable Fields of application: Large series production Clamping from outside to inside (external clamping) Clamping from inside to outside (internal clamping) Material Tempered tool steel Finish Surface hardened Functional surfaces precision grinded Ground in and clearance-free adjusted base jaws Scope of delivery 1 Centre-clamping vise with operating instructions 1 Pair soft block jaws Accuracy Centering accuracy ±0,005 mm* Repetition accuracy 0,003 mm Pairing accuracy 0,01 mm * to the alignment holes on the bottom side Individual additional functions Central lubrication system Long stroke function Jaw stroke with pull down system Quick-change jaw system Floating function Spring activated Airsensoring Cleaning of the workpiece support Pressure holding function Clamping stroke monitoring Clamping force monitoring Practical advice Sealing air connection If necessary, additional sealing air offers protection against the permeation of coolants and dirt. Accessories Clamping jaws General accessories Required clamping force The clamping force of the pneumatic and hydraulic centre-clamping vises and compact vises depends on the operating pressure. A clamping force regulation is linear through pressure change. The operating pressure to be set depends on influencing variables for example workpiece geometry, version of clamping jaws, work material, work conditions and so on. Due to the above mentioned variables it can be necessary to adjust the torque value individually.
