3 Types Diamond of Roller Dresser 1. Terminology 1) Dressing : The process of exposing new abrasive grain and new sharp cutting edges. 2) Truing : The process of forming the working face of the grinding wheel so that it is concentric to the axis of the grinding wheel. 3) Forming : The process of the precise form to the grinding wheel, screw grind wheels and geared grind wheels into the required shape. 2. Dresser s Type 1) Single-point Dresser Dressers with one diamond mounted in one shank. 2) Forming Dresser Dressers with a single diamond that has been polished to the required shape and dimensions mounted in one shank. - Chisel Type : Chisel edge tools for dressing concave and convex radii on all wheel sizes; for contour dressing on centerless grinders; and for angle head dressing - Cone Type : The CONE type dresser contains an elongated diamond cut to a conical point. The included angle of the cone should be as large as possible for maximum point life. 3) Multipoint Dresser Dressers with multiple diamonds mounted in one shank. Type Size of Diamonds Application Characteristic Cylindrical Grinding Usually Big Grit 1.Do not need repair Bearing Type Inner surface Grinding (1/20 ~ 1/2 ct) 2.Enough coolant is required Centerless Grinding 1.Do not need repair Straight line or Step Wheel 2.Due to the less wear-out, Usually Small Grit tolerance is stable Blade Type Radius Wheel (1/40 ~ 1/50 ct) 3.More than 2 grits need to be Profile Revising contacted 4.Enough coolant is required 03

4 Usage Types of of Diamond Roller Dresser 1. Angle of attachment The diamond dresser should be attached at an angle of 10 ~ 15 degrees from the horizontal axis of the grinding Wheel, and at an angle of 10 degrees to the circumference of the wheel. If you rotate the dresser frequently, you can maintain a sharp point and perform ideal dressings. 2. Dressing Procedure 1) The roughness of the grinding edge depends on the peripheral speed and depth of cut, and the total depth of cut of the final dressing must not exceed 0.02mm. * Depth of cut : Fine dressing = ~ 0.015mm Rough dressing = 0.02 ~ 0.03mm 2) To protect Diamonds from thermal damage & carbonization, should correct the exact amount of coolant, the cooling point and the direction of nozzle. 3) The diamond dresser should be turned to prevent dull diamond from glazing wheel and overheating. 4) The dresser should be firmly fixed, to avoid any damage caused by loose clamping. 04

5 Shapes and Types dimensions of Roller of Dresser Diamond dressers 1. Natural DIAMOND Dodecahedron, Crystals, Maccles, Elongated...etc. 2. Synthetic DIAMOND Chemical Vapor Deposition (CVD) Diamond, Mono-crystalline Diamond (MCD), Poly-crystalline Diamond (PCD) 3. Important factors in deciding Diamond size 1) Type of abrasive grinding wheel Abrasive, Grit size, Hardness, Bonding material, Abrasive grinding wheel diameter and width 2) Usage conditions Angle of attachment, Wet or dry, Depth of cut, Peripheral speed, Material to be worked and required surface roughness, Plane grinding or forming grinding, Machine and precision 4. Equation for Diamond s CT Diameter(inch)+2 Width(inch) 10 or Diameter(mm)+2 Width(mm) 250 =CT 5. Requirements when choosing CT for dressers. 1) The bigger grit is required for the harder grit. 2) The bigger grit is required for the bigger grain size. 3) The bigger grit is required for the higher hardness. 6.
