Stone cutting machine is a kind of stone equipment widely used in the industry. Mechanical failure is a problem that may be encountered in production and has a great impact on production efficiency and effects. So what are the causes of stone cutting machine failure and how to solve them?
 
(1) Stone cutting machine has slow cutting speed
 
reason:
 
1. This belt is too loose; 2. The sharpness of the saw blade is reduced; 3. The power supply voltage is low.
 
solution:
 
1. Tighten the belt; 2. Polish the saw blade with a grinding wheel or hard refractory brick; 3. Make sure the cutting machine is working at rated voltage.
 
(2) The stone cutting machine saw blade has a wide swing range
 
reason:
 
1. The output shaft bearing is damaged; 2. The plywood or diamond saw blade is worn; 3. The saw blade is poorly installed.
 
solution:
 
1. Replace the bearing; 2. Replace the plywood or reinstall the saw blade.
 
(3) The stone cutting machine motor does not rotate (no sound)
 
reason:
 
1. The power supply is blocked, the connector is loose, and the power cord is disconnected; 2. The brush is too short; 3. The power switch is damaged; 4. The stator winding is burned; 5. The rotor winding is fused; 6. The propulsion force is too large, causing the switch to trip.
 
solution:
 
1. Repair or replace the power cord; 2. Replace the brush; 3. Replace the power switch with a new one; 4. Repair or replace the stator winding; 5. Replace the rotor; 6. Rest for 5 minutes and then restart.

 
(4) The motor of the stone cutting machine rotates, but the saw blade does not rotate when it is unloaded but loaded.
 
reason:
 
1. The gearbox gear is broken; 2. The semicircular key is broken;
 
solution:
 
1. Replace the gearbox gear; 2. Replace the semicircular key.
