SAP Clamping ring for grinding between centers

"Automatic driving dog for grinding processes between centers"

The concentric chucks of Type 3KCHP can be «converted» into a compensating chuck using an SAP kit. This design feature allows the machining between centers of critical shaft-type workpieces. The floating clamping ring ensures that the workpieces are not subject to any deformation due to clamping forces. A further advantage offered by this arrangement is that the concentric chucks do not have to be dismounted and replaced by a standard compensating chuck.

  • Adjustable in clamping force and for different clamping diameters
     

Advantages

  • Fast retooling of the KCHP/VKCHP between centric clamping and for grinding between centers
  • The KCHP does not need to be dismounted for between-center operation
  • No deformation when clamping long and thin shaft-type workpieces
  • Highest precision when grinding between centers
  • Individual clamping rings and clamping shoes are available upon request, custom-made to your specific workpieces
     
SAP Standard Kit – The optimal addition to your KCHP

SAP Standard Kit – The optimal addition to your KCHP

Our SAP standard kits offer an optimal setup solution if you want to use your grinding machine as flexibly as possible and require grinding operations between centers. The SAP tooling can be mounted to the existing interface of the KCHP/VKCHP. The centering point on the chuck can be aligned to micrometer precision utilizing adjusting screws. Each SAP clamping ring has a variable clamping range, which can be easily adjusted according to the workpiece to be machined. Diameter-defined clamping jaws in various materials are also available on request.

 

SAP special solutions for specific requirements

Special solutions can be offered for specific requirements. 
For example, these solutions enable higher clamping forces or clamping jaws made of brass to clamp ground surfaces without damaging them. Please do not hesitate to contact us!
