Diaphragm Chucks
Diaphragm Chucks are primarily used for light accurate turning, fine boring, facing and grinding operations.Diaphragm Chuck enables improved accuracy and consistent concentricity to be obtained during precision machining operations.
Type D
- Size Range: 8″ – 12″ (210mm – 315mm)
- Number of Jaws: 3 Jaws
- OD or Pitch Line Clamping
- Centrifugal Force Compensation
- Proofline Sealed
Type D diaphragm clamping technology with quick jaw change at its best – for hard turning, grinding, high precision turning.
SIN-DFR
- Special cylinder to actuate diaphragm chuck
- Up to 70 bar
- Central bore for air/coolant, 1 or 2 media
- Large/small piston area for opening/clamping
- Stroke control via LPS-XS
The SIN-DFR is a closed center rotating hydraulic cylinder to to actuate diaphragm chucks.
D-KOMBI
- Size Range: 8″ – 12″ (210mm – 315mm)
- Number of Jaws: 3 Jaws
- Radial and Axial Clamping
- Flat Gripping Force Curve
- Proofline Sealed
D-KOMBI Quick Jaw Change Diaphragm Chucks are ideal for clamping of thin walled workpieces in hard turning and grinding applications. The operation is based on the elastic deformation of the diaphragm, so there are no sliding parts and no friction.
ZHVD-DFR
- Special cylinder to actuate diaphragm KOMBI chucks
- Up to 60 bar
- Central bore for air/coolant, 1 or 2 media
- Jaws for pitch line or outside clamping
- Stroke control via 2 x LPS-X
The ZHVD-DFR is a double piston rotating hydraulic cylinder to actuate diaphragm KOMBI chucks.
D-PLUS
- Size Range: 260mm-315mm
- Number of Jaws: 3 jaws
- Through Hole: 32mm – 50mm
- Centrifugal Force Compensation
- OD or Pitch Line Clamping
The first and only open center diaphragm chuck in the industry. Giving super high-precision turning, grinding or milling operations a superior final finish, the D-Plus Diaphragm chuck is ideal for shaft type work pieces, such as input and output shafts, where sub-micron accuracy is mandatory.
Type D-VARIO
- Size Range: 8″ (215mm)
- Fine adjustment of the center line
- Key Lock System = Quick positioning of jaws for gears with different number of teeth
- Jaws for pitch line or outside clamping
- Proofline Sealed
Type D-VARIO offers a Flexible solution for grinding with quick adjustment for short set up times.
RU-2-20
- Universal for air, oil or coolant
The RU-2-20 allows for double piston cylinder ZHVD-DFR for D-chucks. Rotary union for media supply for rotating cylinders. Universal for air + oil/air + coolant. Can also rotate dry (without medium applied).
CPG
- For Diaphragm Chuck D-VARIO and Face Driver FDG
Easy installation for grinding and turning machines without hydraulic unit.
