Procedures for Braille-OZ unit







Braille-Oz unit mounted in collet







This information is a GUIDE ONLY as different materials may require slight variations.
Operation into Aluminium and Stainless Steel is not recommended until the operator is
experienced with using the Braille-Oz inserter.

THE FOLLOWING DIRECTIONS ARE FOR ENGRAVING MATERIALS ONLY

1. Drill Braille text holes to MEASURE 1.5mm diam (60thou) and 1.1mm deep (44thou) IN MATERIAL with cutting tool. THESE MEASUREMENTS ARE CRITICAL FOR THE SUCCESSFUL OPERATION OF THE UNIT AND SHOULD BE MEASURED WITH VERNIERS.
2. Measure the size of the pre-drilled holes the enclosed pin - must fit FIRMLY into the hole if the pin does not fit into the hole DO NOT PROCEED you WILL damage the unit.
3. Remove drill from router spindle and install Braille-OZ attachment (LOADED WITH BALLS). If you have a tool changer, the Braille-oz unit should be selected from the turret.
4. Calibrate the Braille-Oz unit to the machine.
5. Move the installed unit to the area over the pre-drilled text holes.
6. Set the height for the Braille-Oz attachment to the material.
7. Machine Parameters in the software for Braille-OZ unit must be as follows (for plastics only)
   
   • Spindle turned OFF
   • Spindle lift set to a MINIMUM of 5mm (.200")
   • Depth set to approx 3.5mm. (.140")
   • Feed speed for XY axis approx 45mm per second (1.8" per sec)
   • Z speed in plastics approx 2mm per sec (.08"per sec)
8. Re-run the Braille text using the above parameters to install the balls in the pre-drilled holes.

PLEASE NOTE: IT IS STONGLY ADVISED THAT TEST DRILLING BE PERFORMED ON A SCRAP OF THE SAME TYPE OF MATERIAL --------------the DRILLED HOLE must measure 1.5mm Diam (60 THOU) x 1.1mm deep(44 THOU) - a 1.5mm drill may not drill a 1.5mm hole. Suggest 4000 to 6000rpm for cutter speed in plastics for consistent results.

We have found that different brands of engraving material will drill out at different sizes so it is
important to drill and measure test holes

If unit is loaded or re-loaded with balls, make sure nose-cone & brass cap are both tight.

IMPORTANT NOTE: THIS UNIT MUST NEVER HAVE OIL OR ANY OTHER LUBRICANT APPLIED.
