This text will talk about the performance of Different Diamond Grinding Wheel Bonds and introduction to Processing Grinding Machine.
Diamond grinding wheel is made of abrasive grains, bond and base. The bond is an indispensable part of the production of diamond grinding wheel, and its’ role is to bind the abrasive grains together. The diamond grinding wheel bonds mainly include resin, vitrified, metal and electroplated.
The following is detailed information about the application of diamond grinding wheels with different bonds:
| Work-piece | |
| Diamond Grinding Wheels with Resin Bond | Tungsten Carbide |
|
Diamond Grinding Wheels with Vitrified Bond |
Agate/Silicon/Jade/Diamond |
| jewel/Magnetic materials | |
| Diamond Grinding Wheels with Metal Bond | Glass products/ Ceramic products/Silicon Carbide products |
| Diamond Grinding Wheels with Electroplated Bond | Molding grinding |
Diamond grinding wheels when high-speed grinding require small vibration, high linear velocity and machine stability, so that it can fully play its’ role. Correspondingly, it has some requirements for grinder.
(1) Diamond grinding wheel spindle rotation accuracy is higher.
(2) Grinder stiffness is better, the general requirements of about 50% higher than the average grinder, usually not less than the number of 100N / μm level.
(3) Grinder feed system should reach to high accuracy, and feed rate should be uniform and correct. The minimum longitudinal feed speed should reach 0.3m / min, and horizontal feed (depth of cut) should reach 0.001 ~ 0.002mm / single stroke to ensure Grinding dimensional accuracy, geometric shape accuracy and surface roughness.
(4) To have a more complete grinding fluid filtration and supply system, the filtration accuracy should be less than 0.5μm.
(5) Each part of the grinder should have the corresponding vibration and vibration isolation measures, diamond grinding wheel should be fine dynamic balance.
All in all, the quantity of the diamond grinding wheels bond is many. While, how to choose the most suitable bond totally depends on the material of the work-piece. Only in this way, the grinding efficiency of the diamond grinding wheels can be fully enhanced.
