cutting elements |
band broking |
sawing deviation |
sawtooth crack |
surface rough |
sawtooth wear too fast |
Adjusting the sawing machine |
two guide rods should be located close to the workpiece guide block is wearing parts, must be regularly checked and timely replaced. |
The broken belt guide block is worn or the adjustment distance is too large |
The broken belt guide block is worn or the guide rod is loosening or shaking |
|
|
|
Adjust the driven pulley to achieve the smooth operation of saw blade without dropping, stringing and biting the stop of the pulley. |
the belt wheel is badly worn |
|
|
|
|
The iron brush used to remove sawdust is a vulnerable part. It should be checked and replaced in time. |
|
|
The iron brush is damaged, and the saw belt groove is blocked by cutting debris |
|
The iron brush is damaged and cannot work properly |
Adjust the driven pulley to have proper tension. For the saw belt used for a long time, the tension should be compensated and correctly matched with the concentration of cutting fluid (coolant). |
saw belt tension too high |
saw belt tension too low |
|
|
|
Correctly mix the cutting fluid (coolant) concentration |
|
|
|
|
too low cutting fluid (coolant) or too low coolant concentration |
cutting parameters |
Correct selection of saw band linear speed |
|
saw band linear speed too low |
|
saw band linear speed too low |
saw band linear speed too low |
correctly Choose saw feed line rate |
saw band feed ratetoo large |
saw band feed ratetoo large |
saw band feed ratetoo large |
saw band feed ratetoo large |
saw band feed rate too large or too small |
Band saw blade selection |
according to the characteristics of the workpiece to be cut, the tooth shape and the specification of the saw band are correctly selected |
tooth saws too smal |
tooth saws too smal |
tooth saws too smal |

and the new saw band is used, the initial running-in is needed, the parameters are gradually increased from low speed and slow feed, For maximum service life |
|
|
|
band saws no running or running time short |
band saws no running or running time short |
Do not forcibly use Saw bands that have exceeded their service life |
|
sawtooth worn and scrapped |

According to the characteristics of the workpiece to be cut, correctly select the tooth hardness |
|
tooth hardness Over smal |
tooth hardness over small |
|
tooth hardness over small |
The cut artefact |
Observe the working surface for defects and inclusion of sand |
|
|
|
|
sand or rust Poor workpiece surface, |
to cut into a bunch of workpiece, ensure correct clamping method |
|
|
the workpiece moves during cutting process |
