Is it possible to grind diamonds with the machine?
Yes it is! Here is what you need: Grinding machine Joy-1, raw diamonds ideally already sawn, a cast iron disk 150 x 8 mm, poly crystalline diamond grinding powder of different grain measure, holding claws and an instruction – plus a lot of patience! Used holding claws are frequently offered on the internet. Poly crystalline diamond grinding powder is sold by the Moppes company in Switzerland. As instruction we recommend the book “Diamond Cutting” by Basil Watermeyer. Sawed raw diamonds are purchased best at well-established diamond trading firms and not on the internet.
