(Blade Breakage)

• Incorrect blade
• Blade tension too high
• Excessive feed
• Incorrect cutting fluid
• Wheel diameter too small for blade width
• Worn or chipped pressure block
• Blade rubbing on wheel flange
• Teeth in contact with work before starting saw
• Side guide to tight

• Check tooth selection
• Reduce blade tension
• Reduce feed pressure
• Check coolant recommendation
• Use narrower blade
• Replace worn pressure blocks
• Adjust wheel alignment
• Allow blade clearance above work

(Premature dulling of teeth)

• Blade on machine backwards
• Improper blade break in procedure
• Hard material or heavy surface scale
• Material is hardening
• Improper cutting fluid or mix ratio
• Speed or feed too high

• Install blade correctly
• Refer to recommended procedures
• Check material hardness and surface condition
• Increased feed pressure
• Follow coolant mixing procedure

(Inaccurate cut)

• Guide arms too far apart
• Blade worn out
• Over or under feeding
• Improper tooth pitch
• Cutting fluid not applied properly
• Too many teeth for material cross section
• Guides worn or too loose

• Adjust guide arms closer to material
• Replace blade
• Check cutting recommendations
• Use proper tooth selection
• Adjust coolant nozzle
• Use proper tooth selection
• Tighten or replace guides

(Teeth fracture)
Back of tooth

• Saw guides not properly adjusted
• Incorrect feed or speed
• Incorrect blade
• Material moves in vise

• Align or adjust saw guides
• Refer to cutting recommendations
• Use proper blade types and pitch
• Inspect and adjust vises

(Teeth Fracture)
Front of tooth

• Material loose in vise
• Incorrect tooth pitch
• Feed too fast
• Speed to fast

• Adjust vises
• Use proper tooth selection
• Reduce feed rate
• Refer to cuttingrecommendation

(Teeth stripping)

• Improper blade break in procedure
• Speed too slow
• Feed pressure too high
• Tooth jammed in cut
• Poor cutting fluid application or ratio
• Hard material or heavy scale
• Wrong blade pitch
• Work spinning or loose nested bundles

• Follow proper break in procedure
• Refer to cutting recommendations
• Reduce feed pressure
• Do not enter new blade in that cut
• Adjust coolant flow and ration
• Check material or surface hardness
• Use proper tooth selection
• Tighten vises or use nesting clamps
• Install blade correctly

(Wear on back of blade)

• Excessive back-up guide preload
• Low blade tolerance
• Incorrect blade (Carbon steel type)
• Excessive feed rate or pressure
• Damaged or worn pressure block
• Guide arms spaced too far apart
• Blade rubbing band wheel flanges

• Adjust pressure blocks
• Refer to operators manual
• Switch to a Bi-Metal blade
• Reduce feed rate or pressure
• Replace pressure block
• Adjust guide arms closer to work
• Adjust wheel alignment

(Rough cut)

• Dull or damaged blade
• Incorrect feed or speed
• Blade not supported properly
• Low blade tension
• Incorrect tooth pitch
• Guide arms too far apart

• Install new blade
• Refer to cutting recommendations
• Adjust or tighten guide arms
• Refer to operators manual
• Use proper tooth selection
• Adjust guide arms closer to the material
