3-3 MILLING BUR SELECTION AND REPLACEMENT
3-3 BUR SELECTION AND REPLACEMENT
3-4 KEY POINTS FOR CIRCULAR MATERIALS CLAMPING
Bur replacement, which is very important in daily processing, will directly affect equipment
safety and quality and thus needs careful operation. Therefore, when burs have been used
for a period of time or they will affect processing quality, bur replacement operation should
be executed complying with the following steps:
1.Firstly, execute the "HOME" operation to ensure that the system has been back to the
origin.
2.If the current burs in the spindle do not need to be replaced, click the corresponding
bur buttons in manual mode to let the equipment automatically take out the target burs;
3.Click the “FIRST REFERENCE” button to move the axes to the reference position.
4.Loosen the spindle collet by click the collet button in the manual interface and take out
the burs need to be replaced. Note that the spindle collet is flexible, so hold the burs with
your hands before loosening the collet in order to avoid damage when the burs pop up.
Keep in mind: collaboration is prohibited when operating; every step must also be carefully
confirmed when operating by a single person. Mal-operation on the spindle should be
avoided so as not to cause personal injury.
Any kind of material must be clamped strictly complying with the clamping require-ments,
in order to avoid badness.
1. No processing residue should be left in the holder and cleaning after eachclamping
must be done.
2. Clamps with badness such as bump caused by collision should not be in continual use.
5. Insert the new bur into the spindle collet, make sure the lantern ring reached to the
collet and then tighten the collet by click the collet button agian in the manual interface.
Using lantern ring is to make sure that bur installation depth conforms to the equipment
processing requirements. So please do not directly put the burs without lantern rings into
the collet or bur pouch in the bur repository. At this point, bur replacement is completed.
6.The length of bur handle out of the lantern ring is about 20mm. If the ring of bur moves,
please replace the burs timely; otherwise, there may be risk of crashing and burs fracture.
7. Normally a bur can mill around 180units of crown, when the milling job reach this limits,
we suggest you to replace the burs timely to avoid any bur breakage and collapse,and bad-
ness caused by this .
8. Bur body uses a kind of high-hardness and low-toughness material; when suffered from
external force, it is easy to fracture. So when operating the workpiece loading and cleaning
the processing chamber, be careful not to touch the cutting edge, so as not to cause frac-
ture and personal injury.

13 14
3. There should be no residue on edge of the re-clamped material, which must be cleaned
to prevent fracture caused by uneven force when clamping.
4. When the holder gland is locked tightly, each screw must be tightened up evenly. Do
not tighten up one screw first, and then tighten up the rest ones. This operation will easily
cause uneven application of force and make the workpices fractured and collapsed, or
produce internal stress, leading to fracture during processing.
3-5 Key Points for Glass Ceramic Processing
1. Material plate must be cleaned comprehensively before clamping the fixture of glass
ceramics to prevent badness.
2.Glass ceramic is strictly required to be clamped in special fixtrure and locked with
fastening screws.
3.There should be no foreign impurities and matters in the three clamping holes of the
fixture. They must be cleaned before clamping to avoid causing clamping badness.
4.To ensure that in corresponding position of the bur repository, there are special bur for
glass ceramic processing and check if the bur specification is correct.
5.To ensure that processing cooling system operates smoothly, and effective.
3-6 Abnormity Elimination
There are system information tips on the automatic interface. Under normal circumstanc-
es, it will display "normal"; if abnormality happens, system will prompt abnormal informa-
tion. For security reasons, most operations can only be accepted by the system under
non-abnormal situation; and when performing related operations under abnormal circum-
stances, the system will prompt corresponding information.
Therefore, when the system prompts abnormal information, users can click the "RESET"
button to reset related abnormality. If the abnormality still exists after reset, then corre-
sponding elimination measures should be taken according to abnormality information and
corresponding prompt information.

CHAPTER 4 MAINTENANCE AND MATTERS
NEED ATTENTION
4-1 MAINTENANCE INSTRUCTIONS:
1. Clean the dust in the processing cavity of the equipment every day to make surethere
is no dust accumulation in it; for the moving parts in particular, make sure there is no dust
accumulation in the groove of the spindle sleeve and on the presetting bur surface of the
presetting bur gauge.
2. Clean up the equipment processing cavity before switching processing materials.
3. Clean the dust inside the vacuum cleaner once a week to maintain its suction. (If thed-
ust in vacuum cleaner is not cleaned in time, then the filter will be clogged easily, which will
reduce the negative pressure and the suction power. Finally, part of the dust will enter into
cavity of the equipment, causing internal electronic component damage,and abnormal
alarm and thus reduce the service life of the equipment).
4. Check the water level of the cooling water tank every week and test the water yield of
the pump every day. When the water level is low, make timely supplement or replace-
ment. Right amount of antirust agent must be added into the cooling water.
5. The equipment with a computer built in it is “a special computer for special use”.
Please do not modify system related settings, install or uninstall software. To ensure
normal operation of system, please regularly search and kill computer virus.
6. For glass ceramic processing, it is suggested to replace cooling water and clean
water tank every day to prevent precipitation, so as not to affect processing quality and
reduce the lifetime of burs and cooling water pumps.
