  • Page 8: Xps-16+ Specifications

    Your XPS-16+ has many features so carefully designed and engineered that you may not even be aware of their uniqueness. Once the cycle start button has been pressed, your Darex XPS- 16+ begins taking measurements of the drill on the way to the grinding wheel. It locates the end of the drill, calculates diameter, locates and positions the cutting edge, determines web thick- ness, identifies initial contact point of drill to the wheel and then sharpens.

    Machine Axis Definition X Axis: A crossfeed axis which moves the grinding wheel sideways. C Axis: A rotate stage which turns the drill bit about its axis. A Axis: A swing stage which tilts the drill bit up and down at the rear. Z Axis: An infeed axis which positions the drill bit closer to or further from the grinding wheel.

  • Page 14: Touch Screen Details

    Touch Screen Details Main Operating Screen The screen shot this shows what will be depicted on the touch screen once power has been applied to the XPS-16+. Press the [check] in order to initialize the XPS-16+. The Environmental Door has to be closed for the machine to execute initialization.
  • Page 15 Note: If the point angle entered is beyond the machines limits, the XPS-16+ will default to the nearest value the machine is capable of grinding. If the desired grind angle is less than 115°, the XPS-16+ will automatically prompt the op- erator for additional information.
  • Page 16 Web Thickness There are 3 different modes of drill bit cutting edge alignment available with the XPS- 16+. In order to sharpen the different drill types and sizes, one mode may be better suited than another mode. All 3 modes are accessed via the Web Thickness/Alignment Icon on the Main Sharpening screen.
  • Page 17 Advance Icon When the [Advance] feature is used, the XPS-16+ is finding the cutting edge using a single point of alignment. The [Advance] feature is located in the upper right hand corner of the Alignment icon and is activated by entering any value other than zero. There are several drill types that will require an [Advance] value to be entered by the operator.
  • Page 18 Hone Icon (continued) The XPS-16+ can be used as a HONE ONLY machine. This is accomplished by deactivating the [SHARPEN ICON] and the [SPLIT ICON]. This feature is beneficial for new carbide drills that have not received a cutting edge treatment. Hone times vary depending on the drill size and the type of hone being used.
  • Page 19 XPS-16+ will allow drills files to be sent and retrieved via your computer. Note: File #1 DAREX FILE is factory created and is the default file to start with when creating new drill files. • Press the File Management Icon – a list of the drill files existing on the XPS-16+ will appear.
  • Page 20 Point Split Offset Icon Select the point split type you wish to grind using the Point Split icon already covered in the user guide. Any split geometry you wish to alter can be adjusted using this menu. The user adjustments are: Pressing the Z axis offsets (plus and minus) which will control...
  • Page 21 Key Icon This icon allows access to 2 different secure areas that are not accessible unless di- rectly working with your Darex representative. Each secure area requires a unique password to enter (user locked screen password is ‘55’). Facet Overlap Adjustment Icon This value is calibrated at the manufacturer so that all 4 drill facets intersect in the center of the drill.
  • Page 22 Press this button to make minor wheel offset adjustments. This function might be needed to compensate for new or different grit wheels. 1. Load the factory file DAREX FILE onto the main operating screen. 2. Measure the length of a 3/8” drill bit using calipers.
  • Page 23 Hone Time Adjustment Once the desired Hone type is selected on the Main Menu Screen, press the [TOOLS] icon in the lower right corner of the touch display. Under the [HONE TIME] icon, the operator can input a duration value for how long the drill is to be honed.

    If you start with the Darex file and select “Conic”, turn off the split function, and press the [START] button, the result will be a drill bit that looks somewhat like the one to the right.
  • Page 27 If the angles still look good, adjust the X and Z settings to remove more material (Adjust in the “+” direction), and grind the drill again. It will look similar to Figure C-3. Figure C-3 Adjust X and/or Z deeper (in the + direction), and look at the drill. See Figure C-4.

  • Page 28: Creating A Facet-Style Drill, Step-By-Step

    Adjusting Facet Shape If you start with the Darex file and select “Facet” instead of “Conic”, turn off the split function, and press the [START] button, the result will be a drill bit that looks somewhat like the one to the right.
  • Page 29 4. Upon deciding what starting angles to use, enter them into the split screen here. Back off the X and Z adjustments (in the “–” direction) in the Split adjustment screen about .005” Grind the sample drill with the initial split settings. It will look similar to Figure F-2. Figure F-2 5.

  • Page 30: Copying A Drill, Step-By-Step

    Copying a Drill, Step-by-Step These instructions are meant to be a guide for creating a copy of a drill. It is assumed that you have been able to identify and record the angles and other features of your pattern drill, through whatever means are available to you.
  • Page 31 4. Split adjustment. Start with X style even if drill has a Radial Split. When setting up the split, start with an X split. A Radial split is full of curves and it’s hard to tell where all the lines are so that they can be adjusted correctly.

  • Page 34: Advanced Sharpening Tips

    Advanced Sharpening Tips Geometry • Start out simple and add more features as the drill point is developed. The point and lip relief angles can be treated as absolute values. Split parameters are more relative and require some judgment and “sneaking” towards. •...

  • Page 35: General Maintenance

    Remember: • There is no adjustment for Split Down Angle and Secondary Facet Angle. • Use of ADVANCE is not compensated for in the Split parameters. • Use a silver marking pen to enhance the cutting edge for drill alignment. Use a black marking pen to minimize reflections from the flute area on bright finish drills.
  • Page 36 2. Use a 3/8 HSS standard twist drill, measure the length of drill before sharpening. 3. Call up the Darex #1 file and sharpen a drill. 4. After sharpening the drill, measure the drills new length. MTO should be approximately .005-.007.
