5 Axis Bridge Type Stone Cutting Machine

Bridge type stone cutting machine with 5 axis linkage control,  can implement different complex curved surface processing, profiling, such as kitchen countertop,  tombstone, art decoration slab & rock sculpture etc.

The front-back,left-right,up-down of Tile 5 Axis cnc Bridge Saw can locate and be controlled by the microcomputer to work automatically. The workstation can also rotate 90 degree automatically. It can turn up to an angle of 85 degree. The main electrical elements and components of the CNC machine are all of imported good-quality materials so that is pledges the whole machines precision and long life.

Features of stone bridge cutting machine:

1.Mono-block structure, side beams are fixed on the steel, solid and stable.

2.Equipped with infrared device for precise cutting location

3.Wide crossbeam of bridge structure for large size of slab cutting and it is made of strong cast iron to avoid distortion after long-term use.

4.Guide rail on the crossbeam is in oil bath and it is protected from water and dust

5.Dustproof design of the slide track ensures the precise guide movement & long lifespan

6.Vertical movement of machine head is driven by accurate hydraulic system, and the stroke is adjustable

7.Cross movement of the machine head on the crossbeam is driven by motor equipped with OMRON rotary encoder by which the precision is guaranteed

8.The crossbeam is installed on the side beams by lineal guide track that results in less friction force and provides better flexibility and reliability

9.Worktable can tilt 0-85°

10.The blade head can rotate 90° by hydraulic system to cut the other side of slab without turning its direction

11.Equipped with frequency transducer and PLC, programmable and fully automatic

12.Touch-sensitive operating system, friendly human-machine interface design

Maintenance And Troubleshooting Of bridge type stone cutting machine

Trouble shooting

1.  The table cannot be raised

Fault causes: the bed fails to reach the front limit position or the front limit switch fails;  the relay coil is burnt out, the normally open contact is rusted, or the normally closed contact of the relay is blocked;  the lifting button sb7 fails;  the coil of solenoid valve yv3 is broken or the tap is in poor contact.

2.  The table can't turn left or right

Fault causes: button sb10 or sb11 is out of order;  relay K5 or K6 is broken or contact is not conscientious;  solenoid valve yv5 or yv6 coil is broken or plug contact is poor.

2.  The table can't turn left or right

Fault causes: button sb10 or sb11 is out of order;  relay K5 or K6 is broken or contact is not conscientious;  solenoid valve yv5 or yv6 coil is broken or plug contact is poor.

3  The worktable does not rotate to the left or right

Fault reason: the limit switch SP2 is broken or broken;  the working table is not falling to the bottom.

It is worth noting that if SP2 is broken or broken, although the workbench has fallen to the bottom, the PLC has not received the signal, that is, the signal lamp x17 on the PLC is not on, which is equivalent to that the workbench has not fallen to the bottom.  Therefore, the worktable can not rotate, so the limit switch SP2 should be checked.

4.  Saw blade feed out of control

Fault causes: oil leakage of oil cylinder, aging of piston oil seal, loose sealing;  tight valve core of solenoid valve

Sealing is not tight or due to more impurities in the oil, the valve core is not closed in place, and there is pressure relief phenomenon.

Troubleshooting: first of all, cleaning the solenoid valve spool.  If there are more impurities in the hydraulic fluid or foam, replace the hydraulic oil.  Then check whether the lifting oil cylinder of the saw blade is leaking oil and the aging of the piston oil seal.

5.  When cutting, the bed moves slowly and deviates

Troubleshooting: if it is unable to clamp at the beginning, it is possible that the clamping cylinder is rusty, which can be removed for cleaning or replacement;  start clamping, and then slowly loosen.  It is mainly to check and clean the solenoid valve core.  If the hydraulic oil foams, foams, and water enters into the deterioration, the obvious performance is that the clamping cylinder automatically relieves the pressure, resulting in the bed moving and cutting deviation, then the hydraulic oil can be replaced.

6.  The motor turns to the bed and does not move the fault reason: the clutch does not act.

Troubleshooting: check whether the relay K12 is in good condition.  Use a multimeter to measure between point 147 and point 102 to determine whether the clutch coil and circuit are in good condition.  Generally, the clutch coil is broken or the plug is not in good contact.

7.  The motor does not turn.
