CUTTING PROBLEMS
6
Saw is cutting out-of-square
vertically.
6.1 Excessive feed force. 6.1
Check settings against Saw Cutting
Parameter Chart.
Reduce Feed Rate setting.
6.2 Blade is dull or damaged 6.2 Replace blade.
6.3 Low blade tension. 6.3 Reset blade tension.
6.4
Too low feed force when cutting
materials that work harden
(stainless steels, nickel alloys)
6.4
Increase feed force setting.
Check that feed rate display does
not drop below 0.20 in/min.
6.5 Stock misalignment. 6.5
Check that stock rests evenly on
conveyor rollers.
6.5 Blade guides. 6.5 Adjust or replace.
7
Saw is cutting out-of-square
horizontally
7.1 Stock misalignment. 7.1
Check for bowed stock.
Re-arrange stock.
7.2 Blade guides. 7.2 Adjust or replace.
8 Blade comes off blade wheels.
8.1 Low blade tension. 8.1 Reset blade tension.
8.2 Excessive feed force. 8.2
Check settings against Saw Cutting
Parameter Chart.
Reduce Feed Rate setting.
8.3 Blade tracking too far off wheels. 8.3 Check tracking, adjust if necessary.
8.4 Excessive wheel wear. 8.4
Check wheel proles. Replace if
necessary.
9 Blade stalls in cut.
9.1 Low blade tension. 9.1 Reset blade tension.
9.2 Excessive feed force. 9.2
Check settings against Saw Cutting
Parameter Chart.
Reduce Feed Rate setting.
9.3
Blade pinched by stock with
internal stresses.
9.3 Use blade with extra wide set.
10 Blade vibrates excessively.
10.1 Blade speed too high. 10.1
Lower blade speed.
(Occasionally increasing speed can
help.)
10.2 Low blade tension. 10.2 Reset blade tension.
10.3
Not best blade pitch.
10.3
Refer to Saw Cutting Parameter
Chart.
If blade pitch is correct per chart:
In solids, try next ner pitch.
In structurals try next ner pitch.
11 Excessive blade breakage.
11.1 Band tension too high 11.1 Reduce blade tension.
11.2 Excessive feed force. 11.2
Check settings against Saw Cutting
Parameter Chart.
Reduce Feed Rate setting.
12 Blade tooth strippage.
12.1
Gullet packing - blade pitch too
ne.
12.1
Refer to Saw Cutting Parameter
Chart for correct pitch.
12.2
Gullet packing - blade brush not
cleaning.
12.2 Adjust or replace blade brush.
12.3 Excessive feed force. 12.3
Check settings against Saw Cutting
Parameter Chart.
Reduce Feed Rate setting.
