Time-consuming, but the process of diamond particles trimming off more, wheel dressing itself consumes large, low-shaping accuracy.

In recent years, scholars from various countries metal cut off wheels have been carrying out a special processing method applied metal bond diamond wheel dresser research work, mainly electrolytic dressing, French dressing spark composite dressing method. Electrolytic dressing method is fast, but shaping accuracy is not high; high precision EDM shaping trimming method, can be either plastic dressing, but shaping slower; composite trimming method spark composite electrolytic dressing, mechanical chemical compound trimming method etc., dressing better, but the system is more complex, and therefore sintered diamond wheel dressing the problem still has not been solved.

In addition, due to the grinding wheel manufacturing process to determine its surface morphology random, each abrasive geometry, distribution and cutting edge which highly inconsistent, cutting wheels and therefore only a few high grinding cutting edge cut into the workpiece, limiting the grinding quality grinding efficiency is further improved.

tile cutting wheels Electroplated diamond grinding wheel

Precisely because of these advantages, plating wheel speed, ultra-high speed grinding occupy the undisputed dominant position. Electroplated diamond grinding wheel metal cut off wheels defects exist: metal coating and the substrate and the abrasive surface is not kept securely combine chemical metallurgical combine, in fact, only be mechanically entrapped abrasive coating metal inlay, and thus a small holding force, efficient grinding diamond particles heavier load shedding (or plating flaking) and lead to an overall failure; increase gripping force must be increased coating thickness, and the results highly abrasive bare chip space is reduced, wheel prone to clogging, the cooling effect is poor, the surface prone to burns. Currently electroplated grinding wheel manufacturing has not been achieved by optimized processing conditions tile cutting wheels required to design the best wheel topography, these single-layer electroplated diamond grinding wheel will be significantly limit its inherent drawbacks efficient grinding applications.

abrasive cutting wheel Replace Precautions

Diamond grinding wheel replacement process Precautions

Wear problems

Any wheel has its use and wear certain reinforced concrete cutting wheels requirements to achieve a certain degree of wear must be re-replacement of the wheel. Not in order to save material, it requires the use of ultra-wear, which is a very unsafe illegal behavior. A general rule, when the wheel wear to a larger diameter than the diameter of 10mm chuck should be replaced with new wheel.

Valid questions

Brought out a new wheel from the Treasury is not necessarily qualified wheel, new wheel even buy from the manufacturers are not necessarily qualified wheel. Any wheel has its certain expiration date, within the validity period of use, it is qualified wheel; than valid use, it is not necessarily qualified wheel. Rules of order "wheel should be within the validity period, resin and rubber bonded grinding wheel rotating storage must be approved flat cutting disc by the test, those who pass the year before use."

Texture problem

During use, if you find a local wheel cracks, should immediately stop using and re-replacement of the grinding wheel, grinding wheel to avoid crushing injury accident.
