Hi, I have VOUMARD make high frequency motorised electric spindle in my grinding machine.Spindle is BM24 type. Ihave replaced the bearings from SNFA make vex35 and vex20 to RHP7007P3 and RHP7004P3. I have ensured the cooling and mist lubrication for both the bearings. My working rpm are 18000 but at 12000 also I am not able to run my spindle. The front and rear bearings are in tandem position among themselves and back to back between themself i.e. >><<. Can somebody guide me what may be wrong in my assembly.  |
