Main function
The multifunctional railway bearing ring ultra precision machine is mainly used for ultra precision cylindrical and tapered roller bearings, outer ring double raceway, and outer diameter sanding belt polishing.
The new multifunctional railway bearing ring ultra precision machine adopts Siemens 808D dual axis servo control system, single station positioning, using two identical oilstones to complete the ultra precision of two parallel raceways with two busbars. The conversion between coarse and fine ultra precision of the two raceways is achieved through automatic changes in process parameters such as workpiece speed, oscillation frequency, oilstone pressure, etc. during the ultra precision process. There is also an independent mechanism that synchronizes the outer diameter of the sanding belt with the ultra precision of the raceway.
The sanding belt is used to press the outer diameter, and the servo control reciprocating motion is used. At the same time, the sanding belt automatically rolls, and the process parameters such as workpiece speed, sanding belt reciprocating speed, and sanding belt pressure are automatically adjustable during the polishing process.
Large processing range: the diameter of the ring raceway is between 114mm and 280mm, the outer diameter is between 150mm and 310mm, the height is between 25mm and 180mm, the weight is between 2-16kg, the surface hardness is HRC59-HRC63, and the raceway angle is between 0 ° and 28 °
