Common faults analysis & solution

Common Faults Reason Analysis Solution
Shaken Improper feed speed
Incorrect teeth type
Clamped loose
Improper tension
Adjust the feed speed
Choose the right teeth type by object’s size and shape
Clamp the object
Adjust tension
Rough sawing surface Teeth passivation or damaged
Improper feed speed
Incorrect teeth type
Improper tension
Not cooling enough
Improper the oriented arms or object
Replace new saw blade
Adjust the feed speed
Choose the right teeth type by object’s size and shape
Adjust tension
Add more cooling fluid
Adjust the oriented arms or object
Scraps stick on the teeth needle Incorrect cooling fluid
Speed too fast
Brush damaged
Incorrect teeth type
Choose the right cooling fluid
Adjust the speed
Change brush
Choose the right teeth type by object’s size and shape

‘T’shape on the back  

(curve, deformed)

Feed speed fast
Long distance between two oriented arms
Saw teeth too small
Alloy orientator damaged or blocked
Tension too small

Adjust the feed speed
Adjust the distance of the oriented arms

Choose the right teeth shape and TPI
Adjust tension or change the alloy orientator
Adjust tension

Slanting sawing

Teeth passivation or abrasion
Feed speed too fast
Incorrect teeth type
Alloy orientator damaged or loose
Object is harder than saw teeth
Some teeth damaged
Long distance between two oriented arms
Scraps stick on the teeth needle
Slanting saw blade

Reload new saw blade
Adjust the feed speed
Choose the right teeth type by object’s size and shape
Change or adjust the alloy orientator
Choose the harder teeth
Reload new saw blade
Adjust the distance of the oriented arms
Check the brush and cooling fluid
Readjust the saw blade
Teeth broken

Object and teeth type unmatched
Feed speed too fast

Saw blade blockedobject loose
Wrong way
Sand buckle
Tension too small

Choose the right teeth type by object’s size and shape
Adjust the feed speed
Check the hydraulic system and clamp
Reload saw blade
Check the rigidity of objectconditions of process or use the used blade
Adjust the tension

Teeth passivation or abrasion too fast

Insufficient running-in
Object is harder than saw teeth
Feed speed too fast
Some hardness pieces
Wrong teeth type
Wrong way
Sawing the former cut by new saw blade
Tension too small

Small feed speed when new blade is running-in at first
Choose the right saw blade by conditions of process
Adjust the feed speed
Chang the object or sawing at new cut
Choose the right teeth type by object’s size and shape
Reload saw blade
Keep away from the former cut
Adjust the tension
Faultage as a line

Tension too small
Speed too fast
Alloy orientator damaged
Fearful abrasion between flange and saw  blade
Incorrect teeth type
Feed too fast

Improper cooling
Saw band touched object when sawing starts
Alloy orientator clamp too close

Adjust the tension
Adjust the speed
Check or change the alloy orientator
Adjust the flange
Choose the right teeth type by object’s size and shape
Adjust the feed speed
Check the cooling fluid
Keep distance between saw blade and object before sawing
Adjust the alloy orientator
Anomaly broken Saw blade is Warping when loaded
Clamped loose
Adjust saw machine
Adjust clamp to close the object
