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 wearing--in period (a cutting

 

Disc not worn--in correctly

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

under-cooled inclusions. These zones, which are

 

 

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.
