Reasons For The Vibration Of The Main Machine Of The Bridge Stone Cutter

The reasons for this phenomenon in bridge stone cutting machine machinery include: improper clearance between the spindle box and bearings; Bearing damage; The flange plate is not clean, and there are bumps and scratches; The spindle is bent or damaged; Loose bearing covers at both ends of the spindle box and improper cutting speed; The selection of the blade does not match the stone; The main reasons for the above fault phenomena are the large jumping of the saw blade.
To eliminate such faults, it is necessary to first focus on inspecting the components of the spindle box, paying special attention to measuring parameters such as the radial runout of the spindle and the end face runout of the fixed flange of the saw blade.
1. Radial circular runout of the main shaft ≤ 0.04; The cross-sectional runout of the flange plate is ≤ 0.08.
2. The perpendicularity of the walking trajectory between the saw blade shaft and the sliding frame shall not exceed 0.05mm, and the perpendicularity of the lifting motion trajectory between the saw blade shaft and the sliding frame shall not exceed 0.05mm.
3. Also check if all fasteners are loose and retighten according to the situation. Check the oil level in the oil pool, and if there is a noticeable shortage, supplement it. Check whether the saw blade swings too much when it rotates, and check the exposure of the diamond of the cutter head, that is, whether the cutter head is sharp. If the cutter head is blunt, the Fire brick can be used for re cutting. Observe whether the operator is operating correctly.
