Quote from: Drilon on December 30, 2024, 09:23:22 PMA source for the CBN wheels for Tormek is https://www.forever-superabrasives.com/CBN-Wheels-for-Tormek.htmlI am a Chinese CBN grinding wheel manufacturer, and I can responsibly say that the grinding wheels for knifegrinders come from Zhengzhou Ruizuan Diamond Tools Co., Ltd. They sell them on Alibaba.
I am sure that this is the company which supplied Knifegrinders with CBN wheels as you can see on their page a video which is identical with Vadims video (Knifegrinders) ,,How to sharpen curved knives on our CBN wheels" at 8:16 min. Hope this helps!
