Flexibility thanks to the modular system

I.D., O.D. or jaw clamping – it's easy with the B-Top3 modular system. Everything fits together. With the MANDO Adapt segmented mandrel, you can change to perfect I.D. clamping in less than 2 minutes. The SPANNTOP adaptation is the right partner if you have reached your holding power and accuracy limits for O.D clamping. And all without removing the chuck!

Basic clamping for small lot

The B-Top3 basic clamping device also has its advantages: The fast jaw change with single-jaw unlocking mechanism and high repeatability is ideal for small lot sizes. Thus, in most cases machining the chuck jaw to size is unnecessary.

Flexibility with system

Also the insert bushing system is configured for small lot sizes and maximum flexibility. It enables clamping devices to be conveniently adapted to your requirement: Closed with ejector, spray nozzles, or with variable end-stop. Just the way you need it.

Better clamping force                         

And the new innovative lubricating system ensures improved clamping force behavior of the wedge bar principle.

You have never turned like this before.

Key advantages

  • Extremely fast conversion [2 min.] to I.D. clamping with the MANDO Adapt mandrel-in-clamping-device or to O.D. clamping with the SPANNTOP Adapt chuck
  • Through-bore passage bushings or end-stop bushings that can be changed from the front
  • Fast jaw change with individual unlocking at high change-over accuracy and suitable for the »Reishauer« system, straight gear cutting
  • High degree of operator safety with minimum change-over time
  • Proven wedge rod mechanism
In detail
  1. Jaws with straight serration
  2. Large chuck bore with CENTREX interface for ultra-precise change-over without adjustment
  3. Innovative lubricating system, consequently longer lubricating intervals and improved clamping force behavior
  4. Operational safety when changing jaws due to ball mechanism: The actuating wrench can only be pulled off the wedge bar is properly engaged in the master jaw
  5. Locking mechanism in the wedge bar enables a secure master jaw position and thus guarantees secure mesh of the master jaw gearing in the wedge bar
  6. Different insert bushings for fast adaptation to the machining requirements
