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.
