YTQQ cnc stone cutting machine




The automatic bridge cutting machine is produced by our company, mainly used for cutting marble, granite, artificial marble, microcrystalline stone and other plates. It is a necessary plate piece cutting equipment for large and medium-sized stone processing plants. Due to the use of microcomputer control technology, laser marking, magnetic ruler positioning, it has the advantages of high degree of automation, high precision of cutting plate size, convenient operation, etc., correct maintenance of the equipment is of practical significance, and the professional level of maintenance personnel is also proposed A better request. The following are common faults and troubleshooting methods during the use of this equipment.

1. The equipment is not running smoothly, and the host vibration occurs during the cutting process

The reasons for this phenomenon are: the matching clearance between the spindle box and the bearing is not suitable; the bearing is damaged; the flange is not clean, bumped and scratched; the spindle is bent or damaged; the bearing caps at both ends of the spindle box are loose, and the cutting line speed is inappropriate; The head selection does not match the stone; the saw blade jumps are the main reasons for the above failure phenomenon.

To eliminate this type of failure, first focus on checking the headstock components, especially to measure the radial runout of the spindle, the end face runout of the saw blade fixing flange and other parameters.

1. Radial circle runout of main shaft ≤0.04; flange section runout ≤0.08;

2. The verticality of the saw blade shaft and the sliding frame's trajectory is not more than 0.05mm, and the verticality of the saw blade shaft and the sliding frame's lifting motion trajectory is not more than 0.05mm.

3. Also check whether the fasteners are loose, and re-tighten them as the case may be. Check the oil level in the oil sump, if it is obviously insufficient, it should be replenished. Check whether the saw blade swings too much when it is rotating, and check the diamond exposure of the cutter head, that is, whether the cutter head is sharp. Observe whether the operator is operating correctly.
