Diaphragm Chuck Super High Precision

Diaphragm chuck is a sealed chuck used for super high precision work. It provides almost absolute repeatability. The chucks are mainly used in finishing applications, whether it is turning, grinding or milling.

Super High Precision Diaphragm Chuck

Main Features:

Repeatability – diaphragm chuck's repeatability is within 0.0005MM or 0.00002". It is guaranteed.

Stable Clamping – The work piece clamping is stable even over 8000rpm. Thanks to unique design, the jaws are not affected by the centrifugal force. Sub-micron accuracy and super fine finish are assured under high speed machining.

Flexible clamping power – In case of both, internal and external chucking, and the air pressure can be adjusted with great flexibility to the value which suits an application by an air regulator. This feature provides the mechanist the possibility to machine parts with “thin walls” without damaging or deforming the part dimensions.

Maintenance Free – The high precision diaphragm air chuck does not require lubrication. It is a sealed chuck. A unique design prevents penetration of cutting chips, swarf into chuck body. Thus, this DC is ideal for any CNC turning, vertical machining and precise grinding operation.

High Durability and Stability – Jaw and front cover are made of special materials which have been heat treated specifically to maintain rigidity and accuracy over the long term.

Flexible Application – This diaphragm chuck can accommodate both internal and external chucking. Back stops can be designed inside of the work piece, and outside as well by utilizing the external flange.

High Speed Turning Ability – The standard model can be rotated up to 8,000 rpm. A special faster model is available. It includes internal weights for counter balance system that allows spinning the chuck at more than 11,000rpm.

The high precision diaphragm air chuck size ranges from 80MM to 200MM or 3" through 8". Customer may have specific through hole size Diaphragm Chuck upon request (see on the bottom). Diaphragm tandem chuck is available in 100MM and 150MM or 4" through 6".
