A high cobalt m42 HSS cutting edge electron beam welded to a tough yet fiexible alloy steel backing giving the blade and extremely hard cutting edge , while having a fully fiexible back . The M42 Bimetal band saw blade should be used for cutting solid sections on a production basis , and bimetal band saw blade is particularly impressive on the more difficult to machine materials such as stainless steel , nimonic , titanium and nickel alloys .
On horizontal Band Saw machines the width of the band is always specified by the machine manufacturer and is determined by the width of the bearing surface on the wheels. Slight increases in band width are sometimes permissible but departures from recommended widths are not advisable. It is important that the set portion of the teeth is always clear of the wheels and guide rollers.
PROBLEM |
CAUSE |
SOLUTION |
|
A. Saw dulls prematurely |
1. Band speed too high 2. Feed rate too light 3. Too coarse pitch 4. Coolant improperly directed 5. Band teeth running in wrong direction 6. Saw idling through cut 7.Improper break ¡§C in on new blade width 8.Improper saw guides for band 9. Inferior quality blade |
Reduce speed Blade might be rubbing, try increasing feed rate Use finer pitch Apply at point of cut Re ¡§C fit band correctly Keep teeth engaged. Use positive feed pressure Reduce feed rate by a 1/3 on first few cuts
Replace with correct ones Replace with B90 M42 |
|
B. Saw loses set |
1. Saw speed too fast 2. Saw rubbing against vice or tunning deep in guides 3. Not using coolant 4. Blade not set square to vice |
Dectease speed prematurely Check cutting path of blade and size of guides
Try to introduce it Adjust guides to vice to ensure blade runs square |
|
C. Blade develops camber. |
1. Feed pressure too heavy 2. Saw guides too far apart 3. Blade riding against flange on wheel 4. Roller guides not properly adjusted 5. Band Saw pitch too fine 6. Hard inclusion in material bening cut 7. Set removed by guides |
Cheak chip formation and re ¡§C adjust Adjust closer to the work Tilt wheel for proper tracking
Re ¡§C adjust Use coarset pitch Dectease feed rate
Adjust or chamfer guides |
|
D. Band twisting |
1. Saw is binding in cut 2. Saw guide arms positioned too far apart 3. Insufficient tension |
Decrease feed rate ¡§C check blade tensioning is sufficient Adjust correctly ¡§C as close to work as possible
Increase band tension |
|
E. Band Saw blade gullets loading up |
1. Too fine pitch 2. Band speed too fast 3. Cutting dry 4. Chip brush not working |
Use coarset pitch Reduce speed and check chip formation Use coolant Replace or repair |
