Precision Power Chuck: KCHP/VKCHP

Precision Power Chuck: KCHP/VKCHP

The lightweight KCHP/VKCHP precision power chucks have been specifically designed for use on cylindrical grinding machines. To ensure a flawless long-term and virtually maintenance-free operation, the chucks are hermetically sealed against contamination and are oil-filled for permanent lubrication. Precision jig-ground locating bores ensure a quick and accurate jaw change, independent of the chuck.

 

  • High precision ≤ 0.002 mm
  • Sealed, suitable for grinding machines
  • Precision interfaces between base and top jaws
  • Low maintenance
  • Possible to interchange jaws between chucks of identical design

Compensating Chuck: OVEKA & KA

Compensating Chuck: OVEKA & KA

Suitable for the grinding of all shaft-type workpieces, OVEKA/KA compensating chucks are the ideal interface between the workpiece and the machine tool spindle when grinding between centres. An innovative design ensures that the actual clamping force is not applied until all of the chuck’s jaws are sitting flush against the workpiece’s clamping location.

 

  • Patented circulating lubrication system
  • Highly sensitive compensation mechanism
  • Extremely low maintenance 
  • Hydraulically or drawbar actuated 
  • 2, 3 or 4-jaw options available in different size

High-Precision Tool Grind Chuck: TGCP0

High-Precision Tool Grind Chuck: TGCP0

Ideal for the manufacturing or re-sharpening of monoblock tools (end mills, drill bits, taps or reamers), while guaranteeing the highest concentricity across the whole clamping range, from Ø 5 mm to Ø 20 mm. A comprehensive range of accessories ensures that the chuck can be utilised optimally in automatic and manual mode. An active air purge system protects against contamination.

 

  • Highest precision ≤ 0.005 mm
  • Standard clamping range Ø 5 mm to Ø 20 mm 
  • Reduction of set-up times
  • 2 versions available - TGC actuated by a pneumatic cylinder and FTGC pneumatically actuated at the front end

Precision Diaphragm Chuck: VMCHP

Precision Diaphragm Chuck: VMCHP

The pneumatically actuated diaphragm chuck family 6VMCHP guarantees clamping of workpieces at the highest level of precision and delivers a repeatability of ≤ 0.002 mm. The pull-back effect of the diaphragm means that workpieces are pulled back against the end-stop, which ensures that tight linear tolerances can be maintained reliably during the whole manufacturing process.

 

  • High precision ≤ 0.002 mm
  • Opening stroke suitable for automatic loading
  • Axial end-stop mounted directly on chuck body offering absolute stability
  • Coolant supply via central bore (through hole)
  • Precision interfaces for top jaws; no need for regrinding the clamping section
