  • Bearings reduce thermal deformation of machine tools

    introduction: Under the influence of internal and external heat sources,The parts of the machine tool will have different degrees of thermal deformation,The relative motion relationship between the workpiece and the tool is broken,Also a quarterly decline in machine tools。For CNC machine tools,Because the whole process is controlled by computational instructions,The influence of thermal deformation is even more serious。To reduce thermal deformation,The following measures are usually adopted in the structure of CNC machine tools。 1.Reduce fever The main heat source of thermal deformation occurs when the machine is heated inside,The heat source should be separated from the main engine as much as possible。 2.Controlled temperature rise After taking one

  • Basic points of bearing routine inspection

    introduction:Clean the surface of the machine before inspection,Then remove the bearing[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Peripheral parts。Oil seals are fragile parts,Careful disassembly is required,Do not apply excessive force,Then carefully inspect the oil seal and its surrounding parts,If adverse symptoms have been shown,Be sure to replace,Bad oil seals can cause bearings
