Troubleshooting – Blade and Cutting Problems
Problem | Probable Cause | Solution | |
|
|
| |
| Incorrect lubricant/coolant fluid | Ensure proper coolant flow. | |
|
|
| |
| Material too hard | Check the cutting speed, feed speed and air pressure | |
| parameters and the type of blade you are using. | ||
|
| ||
|
|
| |
|
| With a new blade it is necessary to start cutting at half | |
|
| feeding speed. After the | |
| Disc not | surface of about 300 cm2 for hard materials and about | |
|
| 1000 cm2 for soft materials) the cutting and feed | |
|
| speeds can be brought up to normal values | |
|
|
| |
Teeth breaking | Disc with excessively fine | The swarf wedges into the bottom of the teeth causing | |
tooth pitch | excessive pressure on the teeth themselves | ||
| |||
|
|
| |
|
| The surface of the cut may have undergone work | |
| New blade inserted in a | hardening. When starting work again, use a lower | |
| cutting speed and head feed speed. A tooth from the | ||
| partially completed cut | ||
| old blade may be left in the cut: check and remove | ||
|
| ||
|
| before starting work again. | |
|
|
| |
| Work piece not clamped firmly | Any movement of the work piece during cutting can | |
| cause broken teeth: check the vise, jaws and clamping | ||
| in place | ||
| pressure. | ||
|
| ||
|
|
| |
| Feed speed too slow | The blade runs over the material without removing it: | |
| increase feed speed. | ||
|
| ||
|
|
| |
| Cutting pressure too high | Reduce cutting pressure. | |
|
|
| |
| Blade speed too high | The teeth slide over the material without cutting it: | |
| reduce the blade speed. | ||
|
| ||
|
|
| |
Rapid tooth wear | Insufficient coolant | Check the coolant level and clean coolant lines and | |
nozzles. | |||
| |||
|
| ||
|
|
| |
| Incorrect fluid concentration | Check and use the correct concentration. | |
|
|
| |
|
| The materials may present altered zones either on the | |
|
| surface, such as oxides or sand, or in section, such as | |
| Material defective | ||
|
| much harder than the blade, cause the teeth to break: | |
|
| discard or clean these materials. | |
|
|
| |
| Feed speed too high | Reduce blade speed. | |
|
|
| |
| Teeth in contact with material | Always check the position of the blade before starting | |
Broken blade | before starting the cut | a new job. | |
|
|
| |
| Insufficient coolant | Check the coolant level and clean coolant lines and | |
| nozzles. | ||
