Troubleshooting

SOLUTION

PROBABLE CAUSE

PROBLEM

Cuts not orthogonal or inclined

Head downstroke speed too

fast

Reduce head downstroke

speed

Widia inserts worn

Replace

Inserts loose

Adjust width

Blade guide head positioned

wrongly

Move mobile head up to the

workpiece using the guide

plate to leave free only that

part of the blade actually

needed to make the cut

Orthogonality of blade to

workpiece rest shoulder

Check and realign the blade

guide heads, then reset the

blade orthogonality with the

shoulder using the adjust-

ment pin at 0

; then set the

stops at 45

right and left by

means of the appropriate

screws

Perpendicularity of the blade

to the work surface

Check and realign the blade

guide heads then adjust the

blade using the appropriate

screws so that it is perpen-

dicular to the work surface

Blade tension incorrect

Bring pressure up to 60 Bar

Blade worn

Replace blade

Tooth pitch unsuitable

Probably a blade with too

many teeth per inch is being

used; change for a coarser

blade

Cutting speed too slow

Increase the cutting speed

Wrong coolant

Check the water and oil

emulsion; check that none of

the holes or hoses are

blocked; direct the jets cor-

rectly

Broken teeth

Check the hardness of the

material being cut

Broken teeth

Cutting speed too high

Reduce cutting speed

Downstroke speed too high

Reduce downstroke speed
