Clamping system ASH Automation (figure 1)
clamping against the fixed jaw
hydraulically operated, single acting
optionally with integrated stroke measuring system to query the slide position
the stroke measuring can be made by means of the installed sensor technology or the acquisition of the flow rate


In conjunction with the optional stroke measuring system, workpiece dimensions can be directly entered, registered and approached by a control unit. Manual adjustment of the jaw openings is not required. The machine tools must no longer be stopped for setup. This reduces downtimes and sources of error due to manual intervention.

Parts families with different dimensions can be clamped in one clamping system. Time-consuming and expensive fixture changes are no longer required and the machine running time is increased. Also the number of workpiece-specific fixtures can be reduced and thus fixture costs can be saved.

The process safety is positively influenced by the query of all functions. Clamping and operating errors are avoided and scrap rates reduced. Durability and easy maintenance are obtained by the closed design of the clamping system.

Costs for fixture maintenance and thus machine downtime are reduced. The stability of the base and an exact zero point position of the fixed jaw guarantee a high quality for your products.

Special benefits

  • automated setups
  • large hydraulic stroke
  • slide position and clamping force can be monitored
  • optimised swarf protection
  • high stability by pulling clamping principle

Double clamping system DS (figure 5)
clamping against the fixed jaw
DS-H: hydraulically operated


For medium-sized and large series: Double clamping system DS hydraulically operated for efficient machining of workpieces, preferably with short cycle times. Can also be used arranged in a row for clamping of workpieces which require several clamping points. Compact and user-friendly for 2 optionally 4 workpieces (DS125).
The double clamping systems of the series DS excel by a high level of process safety. The patented guide and sealing system of the clamping systems guarantees a long service life with minimum maintenance. The 3rd-hand function facilitates the insertion of workpieces in a row.

Special benefits

  • high clamping forces up to 40 kN
  • constant overall length and large clamping ranges, 1, 2 or 4 workpieces
  • optimum sealing against swarf and coolants
  • fixing and mounting possibilities for customer-specific clamping jaws
  • mounting possible directly through the base
  • clamping of differently-sized large workpieces
  • high zero-point accuracy by central jaw free of load
  • adjustment for both clamping positions from one side

Concentric vice ZH (figure 6)
concentric clamping
hydraulically operated, double acting


Concentric vices position and clamp workpieces under the influence of the outer contours exactly in a given symmetry axis. They can be used on machining centres, machines tools and machines for end machining as well as within special clamping fixtures.
Hydraulic clamping and unclamping is made by an external pressure transducer with a double-acting circuit. The synchronisation control adjusted free of play guarantees a high centring precision.

Special benefits

  • high repetitive clamping repeatability ± 0.02 mm
  • constant lengths and large clamping ranges
  • mounting position: any
  • fixing and mounting possibilities for customer-specific clamping jaws
  • protection against coolants and swarf by integrated wipers in the clamping slide
  • large slide stroke
  • opening stroke limitation by adjusting screw
  • suitable for the connection to the central lubrication with bed way oil VG 68 (please ask for information)

Accessories for ASH Automation

Clamping power units
Our clamping power units are designed on the basis of standard components in accordance with the respective system requirements. They control the clamping and unclamping of the clamping fixtures, as well the change of clamping jaws and fixture.

Control units
In combination with the robot controller, our electrical control units ensure the smooth running of the automation processes. They control the clamping power unit and process the signals of the stroke measuring system on the clamping system ASH automation.

Screw systems
In combination with the robot controller, the electrical bolting systems ensure the smooth running of the automation processes.

Media couplings
Our media couplings in the STARK zero point clamping systems ensure that energy is provided where it is required. They automatically connect the hydraulic, pneumatic and electrical supply lines to the fixtures.

Application example 3 ( figure 3 ):
Mini clamp MC 60 H
Two hydraulically operated "MC 60 H" on a reversible clamping system with workpiece-specific clamping jaws for 4-axis complete machining. The hydraulic lines are directly in the base plates of the "MC 60 H".

Application example 4 ( figure 4 ):
Hydraulic double clamping system DS-H
Hydraulic double clamping systems "DS 125H" on a long-bed machine. When using two additional floating jaws (always the second after the outside bar), up to four workpieces can be clamped at the same time for machining. The clamping forces are controlled by a separate hydraulic pressure transducer and can be triggered by a the machine control, a foot switch or - as shown- by a valve with turning knob. The clamping forces can be easily adjusted at the power unit and are thus exactly reproducible. The shown clamping jaws are manufactured as per customer's specification, that are available besides the numerous standard elements of the large accessory range.

Application example 5 ( figure 5 ):
Hydraulically-operated concentric vice ZH
Three hydraulically-operated concentric vices "Z 100 H" on a machine for machining of ends. The fully automated plant is in unattended operation. Workpiece-specific jaws clamp different diameters to the always same centre.

Application example 6 ( figure 6 ):
Hydraulically-operated concentric vice ZH
Two concentric vices "Z 160 H" in automatic mode of machine for machining of ends. The next workpiece is ready (top right in the figure), it will be fed by the gripper (above the workpiece being machined), after the previous workpiece was placed to the left. Optimised clamping jaws allow the machining of different components without jaw change. The fully automated plant is in unattended operation.
