| Adjust machine |
Two guide bars should be located closecarelly.The guide pad
of workpiece iswering parts,must be inspected regularly and in
time. |
The guide pad is badly worn or the distance adjustment is too
big |
The guide pad was badly worn or the guide bar had come adrif |
|
|
|
the guide pad is maladjusted |
|
| Adjust passive pulleys to make
saw band work steadly,no dropping,no stringing,no "biting
of pulley tang. |
Pully badly worn |
|
|
|
|
|
Driving pulley badly worn |
| The iron brush to remove the sawdust is wearing parts;it's should
be checked frequently and changed in time. |
|
|
Iron brush damaged,the alveolus of saw band is bloched with
cutting scarp |
|
The iron brush is damaged,can't work normally |
|
|
| Adjust passive pulley to have proper tension
force.The saw band used for a long time,should be compensated
tension force during work. |
The tension of saw band is too high |
The tension of saw band is too low |
|
|
|
The tension of saw band is too low |
The tension of saw band is too low |
| Make cutting fluid(cooling fluid)to the proper consistency. |
|
|
|
|
The cutting fluid(cooling fluid)is too little to its consistency
is too |
|
|
| Cutting parameters |
choose correct linear velocity of saw band |
|
linear velocity of saw band is too low |
|
linear velocity of saw band is too low |
linear velocity of saw band is too low |
adjust the linear of saw band carefully |
|
| choose the correct feed speed of saw band |
the feed speed of saw band is too high |
the feed speed of saw band is too high |
the feed speed of saw band is too high |
the feed speed of saw band is too high |
the feed speed of saw band is too high or too low |
the feed speed of saw band is too high or too low |
the feed speed of saw band is too high or too low |
| The choice of saw band |
choose correct teeth shape and saw band specification
according to the characteristics of cut workpiece. |
the teeth space is too small |
the teeth space is too small |
the teeth space is too small |
the teeth space is too high |
the teeth space is too small |
|
|
| New saw band needs earlier running-period.Increasing parameters
form low feed speed to get maximum working life. |
|
|
|
The saw band didn't run earlier or the runing period was too
short |
The saw band didn't run earlier or the runing period was too
short |
The saw band didn't run earlier or the runing period was too
short |
|
| Can't forced-use the saw band that outstrip
the useful time |
|
Saw teeth have been badly worn and scrapped |
|
Saw teeth have been badly worn and scrapped |
|
|
Saw teeth have been badly worn and scrapped |
| Choose the correct hardness of saw teeth according to the characteristics
of cut workpiece |
|
The hardness of teeth is too low |
The hardness of teeth is too low |
|
The hardness of teeth is too low |
|
|
| cut workpiece |
Check if the workpiece is incomplete or with
sand in the surface |
|
|
|
|
The surface of workpiece isn't good,with sand
or rust |
|
|
| Ensure to clamp correctly when cutting workpiece in bundle |
|
|
Workpiece moves when cutting |
|
|
Clamp the workpiece incorrectly |
