Applicable for dressing angles of grinding wheels and truing of internal grinder & external grinder. Usually the angles are 40° 60° 90° 120°, we can make the angle as per your requirements. They are made of carefully selected raw diamonds mounted in holders by means of special bonds. The dressing tool takes care of two main functions, it removes abrasive grains which have become completely worn out, and it recreates the correct geometric shape of the grinding wheel. Advantages of PCD tool blanks: 1. Long working life. 2. Uniform surface finish. 3. Reduces machine down time. 4. Highly improved workpiece quality and excellent dimensional control. 5. Increase productivity. 6. High material removal rate. 7. Lower cost per piece. 8. The working life of a PCD cutting edge is usually 50 to 250 times longer than that of traditional sintered carbide cutting tools.
