I bought vibration mounts OV-70 for the machine tool right after buying the machine, until they went up in price. But over time, he began to doubt their installation. But until you check, you won’t know, so I decided to try.
The studs on the supports are only M12 threaded, and the holes in the pedestal for them are M16 threaded. For installation, I bought a high-strength stud with an M16 thread and made adapters with two threads from it. I machined and cut threads on studs on a school turning TV-7M, turnkey edges were successfully milled on NGF 110 Sh4 using an Indian rotary table HV-6 and a 4-jaw turning chuck SANOU K72-160 with a cutter with replaceable inserts.
I will give comparative characteristics of common vibration mounts of the OV type:
