Tool Holder Mounting

The Tooling System is designed to be used in a wide variety of equipment. The same general mounting approach is used – securing the Tool Holder in a manner appropriate for the machine’s fixture. As mentioned above the Tool Holder Size is dependent on the Insert to be used. The machine’s holder determines the necessary Shank Diameter of the Tool Holder or the required interface to the Tool Holder. The size of the Eccentric Bushing or Square Adaptor, used to interface with the machine’s holder will dictate the Tool Holder’s Shank diameter. The five following examples demonstrate the flexibility of the Tooling System made available by the various sizes of Tool Holders, Eccentric Bushing and Square Adaptors. The steps listed below are referenced as required for the five Tool Holder mounting examples.Page 10 no page numbers

  1. Select the correct interface for the machine’s holder, a Tool Holder with a 25mm or 32mm Shank Diameter, the diameter and style of an Eccentric Bushing, or the size of a Square Adaptor.
  2. The Eccentric Bushing‘s Shank I.D. or the Square Adaptor’s Shank Diameter determines the Shank Diameter of the Tool Holder required.
  3. Select Tool Holder based on American Standard or Metric Insert to be used and Shank Diameter determined by steps 1 or 2.
  4. If an Eccentric Bushing or Square Adaptor is required, back off the Set Screw(s) in the collar of the Bushing or body of the Adaptor, apply a few drops of oil to the Tool Holder’s shank and slide the Tool Holder into the Bushing or Adaptor.
  5. Rotate the Tool Holder to align the white notch on the collar with the Zero on the face of the Eccentric Bushing. This orientation results in the face of the Insert to be at a 90 degree angle from the Zero point, centered on the Y axis, and allows the flat of the Tool Holder to align with the bolt holes of the machine. Tighten the Set Screw on the collar of the Eccentric Bushing and slide the assembly into the holder on the machine. The flat of the Tool Holder, visible in the Eccentric Bushing’s undercut, remains perpendicular to the fixture’s bolt holes. Use a Swivel Ball-Bearing Point Set Screw in the center hole and flat head bolts on the outside holes to secure. Mount the appropriate Centering Plate on the Tool Holder and use a dial indicator to confirm the Tool Holder is centered in the Y axis.
  6. If alignment is required, adjust by loosening the Set Screw and two bolts securing the Holder to the fixture. Also loosen the Set Screw on the collar of the Eccentric Bushing. Rotate the Eccentric Bushing in the direction of the error. Each gradient line on the face of the Bushing represents a .001 (0.03mm) correction. Rotating the Bushing towards you (clockwise) is a Plus to the Y axis and away from you (counter clockwise) is a minus to the Y axis. Once the adjustment is made, tighten the Set Screw in the collar of the Bushing followed by the Set Screw and bolts in the fixture on the machine. Confirm the adjustment.
  7. Rotate the Tool Holder to allow the locating pin to slide into one of the locating slots. Secure with the Set Screws.
  8. Secure Tool Holder or assembly to the machine’s holder using appropriate Set Screws and bolts.
  9. Use machine controls, dial indicator and the appropriate Centering Plate mounted on the Tool Holder to confirm alignment. Adjust as required. Once the adjustment is made tighten the appropriate Set Screw. Confirm the adjustment.
  10. Remove Centering Plate if require prior to mounting Insert.
