        Professional processing factory of the bearing seat

            The company is a professional manufacturer of bearing seat machining
             First, the vertical bearing structural features and analysis
             Designed to support the main shaft bearing is installed after the requirements are the same vertical plane of the bearing base and the horizontal plane parallel to ensure better, while the axis vibration, high precision. Perpendicularity requirements 0.1MM/300MM, parallel requirements for 0.1MM/600MM, the diameter of the bearing hole 60 of the support hole, the space requirements of a higher dimensional accuracy, IT7, geometry also requires accuracy and concentricity to higher.
             Second, the choice of locating datum
             Plummer block in the choice of this benchmark is selected as the base under the bottom, in the height expectations. Holes and bearing a fixed position between the centers is not very important, because it is a fixed table is a slot on the back and forth in a direction of activity.
             Third, the vertical bearing processing method of choice
             Plane on the bottom plane of the high precision, flatness requirements for 0.06MM, surface roughness larger, too small should not be fixed. , The production is available in a small vertical milling machine milling plane directly, you can achieve processing requirements.
             Hole, bearing bore machining accuracy of IT7, the surface roughness of 0.2μm, fixed holes after rough machining accuracy of the precision can be, not required.
