The thrust bearing inside is broken, and only one radial bearing can be idled, and the torsion force under the load increases. Just replace the bearings.
Shown is the clamping force in kiloN.
In fact, the structure of this table is a pressure gauge, but the clamping force at the center of the display dial is calculated by multiplying the pressure of the hydraulic system by the area of the cylinder piston. >>>More
The tailstock sleeve looks like it's screw-driven, so it won't slip, right? >>>More
It could be that the four screws inside came out.
The platen is stuck in the rails. If the tailstock fastening screw is still loose, see off the screw, take out the pressure plate, and replace the screw.
If you're a modern machine tool, it's a bit of that.
Because the track is grinded, it's not hand-scraped like it used to be, but generally I have to lock the screw, and it's useless to press down the handle lightly, and if the drill bit is bigger, it will be repelled with a little force. >>>More
