I need to measure wear of diamond grind discs use to cut concrete. I dont know if there is a standard for this task. My idea is to measure cutting force, decrement of diameter or weight loss.
Can you give me some information please?
Hi,
I use to do something similar, but instead determine the loss in diamond as well. Company would send us tools that have been used with X rotation (cuts) and we compared it with new wheels. We looked at weight loss, loss in diamond and diameter reduction. The discs were digested so we can separate the diamond to measure the loss.
Hope that helps
Thanks you Victor.
Do you Know if exits a standard to make this wear tests?.
I do not believe that there is a standard. The test should ideally measure spindle RPM, power drawn, torque and feed force. The typical cutting performance outputs are cutting rate (square metres per hour or cm2 per minute, for cutting or sawing, for example, or cm3 per minute for grinding) and segment wear (either a G-ratio or another measure of wear, such as segment height loss per unit area or volume of cut material. The total lifetime can also be an output but must assume linear wear through the whole life.)
We develop a two axis programable machine to make the wear testing of cutting discs. Nearly we will begin the trials!!!
