Electroplated Diamond Wheel advantages: ① plating process is simple, low investment, easy to manufacture; (2) without dressing, easy to use; (3) single-layer structure determines it can achieve a high operating speed, the current foreign have been as high as 250 to 300 m / s; ④ Although only a single layer of diamond, but there is still enough life; (5) For the accuracy requirements of high-rollergrinding wheel plating unique manufacturing method. Due to these advantages, the electroplated grinding wheel high-speed, ultra-high-speed grinding occupy the undisputed dominant position. Electroplated diamond grinding wheel kept defects: metal coating and the substrate and abrasive bonding surface is not kept firmly in chemistry and metallurgy combination abrasive actually only mechanical embedding mosaic coating metal, thus holding force is small, easy to fall off of diamond particles heavier load efficient grinding (or plating into pieces falling off) and lead to an overall failure; coating thickness must be increased to increase the gripping force, the result abrasive reduce the the bare height of chip space, wheel prone to clogging, the cooling effect, the surface is prone to burn. Domestic electroplated grinding wheel manufacturing has not been achieved by processing conditions require optimal design of the grinding wheel topography, the inherent drawbacks of the single-layer electroplated diamond grinding wheel is bound to greatly limit its efficient grinding applications.
Diamond grinding wheel used for a long period of time is inevitable there will be wear and damage, this time our staff need to be promptly replaced, let's take a brief introduction Replacement Notice under the diamond wheel: Wear problems: Any abrasive wheel has its use and wear requirements, wear reaches a certain level it is necessary to replace the wheel. Not in order to save material, super wear requires the use of, this is a very unsafe violations. A general rule, should be replaced with a new wheel when the wheel wear to 10mm diameter than the diameter of the chuck Diamond wheel . Validity of the problem: Brought out a new wheel from the Treasury is not necessarily qualified wheel, and even buy new wheels from the factory are not necessarily qualified wheel. Any grinding wheel has a certain validity period, within the validity period, it is qualified by the grinding wheel; than valid, it is not necessarily qualified wheel. The rules of the grinding wheel should be used within the validity period, resin and rubber bonded grinding wheel storage after one year must be approved by the rotation test, those who pass before use. Texture issues: In the course of grinding wheel local cracks should immediately stop using the re-replacement of the grinding wheel, in order to avoid wheel crushing injury accident Profile dresses .
