3-3 SELECTION AND REPLACEMENT OF MILLING BUR
Bur replacement is very important in the daily processing. It will directly affect the equip-
ment safety and processing quality. Therefore, careful operation is required. When the
bur has been used for a period of time or affects the processing quality, you need to
replace the bur according to the following steps:
1. Execute the “home” function to ensure that system has been homed.
2. If the current bur is not the bur for replacement, you can click the corresponding bur
button under manual mode to remove the target bur. When the bur is removed, click
“SECOND REFERENCE” to move the axes to the reference position.
3. Use left hand to hold tight the milling bur before loosen the spindle chuck to avoid
any injury from the ejected bur( same as picture below ) . Please remember, the equip-
ment shall not be operated simultaneously by several persons. Even when it is operated
by a single person, special care shall be taken in each step, in order to avoid any person-
al injury due to the activation of spindle by mistake.
4. The new milling bur is equipped with collar. Insert the bur handle into the spindle
chuck, ensuring that the collar is against the chuck. Tighten the chuck after it is in position.
The collar is designed to ensure that the bur installation depth meets the equipment
processing requirement. Do not put bur without collar into the chuck or magazine. Now
the bur replacement is completed.
If too much part of the bur is exposed, the tool-cashing will be caused when it turns
over, damaging the magazine. Therefore, the installation position of the bur with collar
must be specified. When the bur is replaced, you shall manually turn it over to check if the
position is correct, in order to avoid any exception.
5. Key points for installation: (Mark the position) to ensure that the exposed part is kept
at the same position each time. Check if there is enough space in the magazine for the
bur twice each day. If not, replace it with a new bur with collar.

13 14
6. When the number of teeth engraved by the bur reaches 150 units, you need to strictly
monitor the bur edge and check if there is any breakage. If you have the 20X microscope,
you can check if there is any breakage to the bur coating and edge and the sharpness of
the bur. The quality of the machine needle must be ensured for the graving of high diffi-
culty.
7. Special notes for T3 bur
The T3 bur we offer is a very small bur (cutting diameter: 0.6mm), which is made of
materials of high hardness and low toughness.
You need to take care of the T3 bur and avoid applying force on it. Take care not to touch
the bur when cleaning up.
3-4 SPECIAL NOTES FOR LOADING MILLING MATERIAL
No matter what type of material is used, the following loading requirements must be
observed, in order to avoid any failure.
1. No residual dust is allowed on the clamp, which shall be cleaned each time when
loading the material.
2. Do not use the clamp with any defect, such as the bulging caused by bumping.
3. No residual dust is allowed on the edge of the material when it is installed. Be sure to
clean it, in order to avoid the breakage caused by uneven force during the installation.
4. When tightening the clamp, be sure to evenly tightening each screw. Do not fully
tighten a screw and then tighten other screws. It will cause uneven force to break the
material or cause internal stress which results in breakage during the processing.
3-5 Trouble shooting
System information will be displayed on the screen during milling process. In case of
any abnormality, the system will show error information on the screen. To ensure
safety, most operations are accepted by the system only in normal situation. When you
conduct the relevant operation in abnormal situation, the system will generate corre-
sponding prompts.
Therefore, when there is any exception prompt, you can click “reset” button to reset the
relevant exception. If the exception still exists after the reset operation, you need to
take the corresponding troubleshooting measures according to the exception message
and prompts, and then execute the reset or restart the software to remove the excep-
tion message.
