ABS System Characteristic

  • High rigidity and high coupling strength.
    The taper wedge effects produced by the clamping screw, the taper screw, and the slide pin enable strong and firm coupling between the head and the adapter.
  • As the cutting torque acts as torsion force on the axis, 50%─80% improvement is achieved for the clamping strength in the coupled portion axis direction.
  • High accuracy is guaranteed.
    An attachment repeat accuracy of 2─3µm is constantly maintained in the coupled portion.
  • From small (φ20) diameter to large diameter (φ200), a wide range of tooling is possible.
  • Internal passage of the coolant (air) is possible without modifications to standard machinary.
  • Tool head extensions are easy through the use of extension pieces.
  • Through the use of reducers, tool head diameters are easily set.

(JP Patent NO.1328669)

When the force F1 presses on the clamping screw, the slide pin moves in the radial direction and impinges on the taper screw, generation the reaction force F2. Since the centers of the clamping screw, the taper screw, and the slide pin are eccentric, a taper connection is made at sites separated by a 180° phase, with the clamping screw and the slide pin on the taper right impingement portion, and the slide pin and taper pin on the taper left impingement portion. The result is that, a vector analysis of those forces shows, as depicted in the diagram above, that the slides move in an identical direction, and the coupling force FA is doubled and transmitted accordingly. Further, cutting resistance generated during cutting becomes torsion stress and is transmitted accordingly. The forces F1 and F2 generated with the clamping screw and taper screw are expanded, and the coupling (jointing) force FA becomes as even greater force, and is generated accordingly.
