          Technical Information -
          Cartridge Style Trepanning Head Diameter Settings

              The Drill Head diameter is set and inspected with a master insert in our final inspection.
              However, the inserts in the market have a tolerance fluctuation so each time you change or
              index the insert, the diameter must be adjusted as per the following method.



                                              1. When a corner change is made on the insert, it must be adjusted to the correct
                                                size or damage can be caused to the head body or work piece material.  DEEP DRILLING - BTA SYSTEM





                                              2. The dimensional guide pad must be slid forward to measure the diameter.
                                                   2.1 Loosen the lock screw and slide the guide pad forward.
                                                   2.2 Re-tighten the lock screw at the measuring position.



                                              3. Measure the diameter with a micrometer.
                                                We recommend setting the tool diameter at h8 tolerance
                                                to the cutting diameter.
                                                If the diameter is incorrect, go to step 4
                                                If it’s correct, go to step 5



                                              4. Adjust the peripheral cartridge
                                                   4.1 First loosen the lock screw of the peripheral
                                                    cartridge and then tighten it slightly.





                                                   4.2 Proceed to adjust the diameter, using the 2 adjust
                                                    screws and measure with a micrometer.




                                                   4.3 When set to the size, retighten the lock screw.
                                                   4.4 Recheck the diameter with a micrometer. If it is still out of tolerance,
                                                    repeat the procedure from step 4-1.
                                                    Please make sure to tighten the lock screw firmly before using. If loose,
                                                    the cartridge may move and cause serious problems during machining.


                                              5. Slide the dimensional guide pad back to the original
                                                position and tighten the lock screw.
                                              6. Replace the inner cartridge and tighten the lock screw.
                                                Please check that all the lock screws are firmly tightened as
                                                they may come loose if vibration occurs during drilling.
