7.2.1 Y Drive Belt Noise
Outline
To ensure the cutting quality, this machine uses the white belt for Y drive with unstretchable and good material in
mechanical property.
For the belt, a noise like a metallic sound may be generated due to the friction between the belt edge and the swaging
flange of the pulley. To reduce the noise, grease up the belt using specified grease.
It is also effective for Y belt damage.
Point to be checked
1. Check the Y-T Pulley Assy (Y Tension Pulley) condition.
Perform [FUNCTION]->[#TEST]->[MOTOR TEST]->[Y
SERVO MOTOR], and check there is no deformation on the
swaging flange of the pulley while the Y is driving.
2. If the swaging flange seems to move up and down while the Y
is driving, or if there is a space between the swaging flange part
and the tooth part, the belt may fracture or a problem of the
transport function may occur.
3. If no such problems as mentioned above, grease up by follow-
ing the instruction below “Procedure”.
There is no difference in performance between MG-A1-GU and SEALUB L101. (Checked up to 1500H )
In duration test with a simulated damage, greased machine's durability is more than 12 times higher than
no-greased one.
