Researching grinding technology one more time didn't help, but force unlock the grinding wheel solved the problem. Thank you for help and for your mods!

Hello! Can anybody help me and tell console name for item "Grinding wheel", so i'll be able to earn it via console command - for some reason i can't earn it ingame, so console is the easiest way to solve my problem. Thank you!
PS Console command to disable/enable technology "Grinding" may help too
