  • Page 25: 2.10 Grinding Wheel Shape

    Assembly Grinding Wheel Shape 2.10 Grinding Wheel Shape WARNING! Always wear eye protection when operating the sharpener. Failure to do so may result in serious injury. The following section explains how to dress a new grinding wheel and how to maintain the shape of the wheel as you use it to sharpen blades.
  • Page 26 Assembly Grinding Wheel Shape See Figure 2-16. Dress the right 1/3 of the wheel at the same angle as the back of the tooth. The shape of the wheel will be refined after the sharpener has been adjusted to grind the blade.
  • Page 27 Assembly Grinding Wheel Shape Maintaining Wheel Shape See Figure 2-17. The shape at which you have dressed the wheel must be maintained. It is especially important to maintain the small radius on the left corner of the wheel. This is the section that wears quickest.
  • Page 28: Sharpener Adjustments

     IMPORTANT! The sharpener is equipped with a cam to sharpen standard Wood-Mizer blades with a “10/30” profile. Other cams are provided to allow you to sharpen blades used for different sawing applications. See Form #502 enclosed for a complete description of how and when to use the two cams.
  • Page 29: Face Grind Adjustment

    Sharpener Adjustments Face Grind Adjustment Face Grind Adjustment As you operate the sharpener, the cam will rotate causing the index arm to contact a tooth and push it to a position under the grinding wheel. The index arm can be adjusted to leave the tooth closer to or further from the grinding wheel so the tooth face is ground lighter or heavier.
  • Page 30: Tooth Height Adjustments

    If you dress the wheel for less back grind, you will have to readjust the depth/back grind knob for the gullet grind. ® Note: Refer to the Wood-Mizer Blade Handbook for recommended tooth height specifi- cations for your sawing application.
  • Page 31: Gullet Grind Adjustment

    How much you need to grind from the gullet will be determined by how much tooth height ® you need (See the Wood-Mizer Blade Handbook for tooth height recommendations). Use the depth/back grind knob to control how much material is removed from the gullet.
  • Page 32: Back Grind Adjustment

    Back Grind Adjustment When combined with a light face grind, back grind should remove enough material from ® the tooth to regain a sharp tip (See the Wood-Mizer Blade Handbook for details con- cerning blade maintenance). It is important to realize that you can grind a blade and not sharpen the teeth. You need to closely inspect the tips of the teeth to determine if you are actually getting a new, sharp tip.
  • Page 33: Sharpener Alignment

    Assembly Sharpener Alignment Sharpener Alignment Use the LTAGA alignment tool as necessary to achieve accurate alignment between the blade clamp and the grinding wheel. IMPORTANT! Do not attempt to adjust the tool gauge points. They have been pre-calibrated at the factory to ensure accurate alignment results.
  • Page 34 Assembly Sharpener Alignment 4. Use a 3/4” wrench to loosen the bottom clamp adjustment bolt. 5. Position the clamp assembly so the front clamp plate touches all three tool gauge points. Secure in position by tightening the clamp adjustment bolt. See Figure 3-5.
