MBS-823DGVI / MBS-827DGVI
FAULT
PROBABLE CAUSE
REMEDY
Tooth Breakage
Wrong tooth pitch or shape
Replace blade with a more suitable
one. See "Material classification and
blade selection" in the
Blade Types
section. Adjust blade guide pads.
Insufficient lubricating, refrigerant,
or wrong emulsion
Check level of liquid in the tank.
Increase the flow of lubricating
refrigerant, checking that the hole and
the liquid outlet pipe are not blocked.
Check the emulsion percentage.
Teeth positioned in the
direction opposite the cutting
direction
Turn teeth to correct direction
FAULT
PROBABLE CAUSE
REMEDY
Premature blade wear
Faulty running-in of blade
See "Material classification and blade
selection" in the
Blade running-in
section.
Teeth positioned in the
direction opposite the cutting
direction
Turn teeth in correct direction.
Poor quality blade
Use a superior quality blade.
Too fast advance
Decrease advance, exerting less cutting
pressure. Adjust the braking device.
Wrong cutting speed
Change speed and/or type of blade.
See chapter on "Material classification
and blade selection
,
”
in the section
Blade selection table according to
cutting and feed speed.
Defects on the material or material
too hard
Material surfaces can be oxidized or
covered with impurities making them,
at the beginning of the cut, harder that
the blade itself, or have hardened
areas or inclusions inside the section
due to productive agents used such as
casting sand, welding wastes, etc.
Avoid cutting these materials or
perform cutting with extreme care,
cleaning and remove such impurities
as quickly as possible.
Insufficient lubricating refrigerant
or wrong emulsion
Check level of liquid in the tank.
Increase the flow of lubricating coolant,
checking that the coolant nozzle and
pipe are not blocked
.
Check the
emulsion percentage.
