Caution• Make sure not to tighten the collet nut when no milling bur is in the collet chuck.
Overtightening the collet chuck may cause the collet nut’s edge to slip out of thecollet chuck’s inner groove. If the edge slips out of the groove, the collet chuck may
stay stuck in the collet holder even when the collet nut is loosened, making it
impossible to remove the collet chuck.
• When fixing the collet chuck in the collet nut, check that the collet nut’s edge isfirmly mated with the groove of the collet chuck. When the edge is firmly matedwith the collet chuck’s groove, the collet chuck will not come out even when pulled
in its axial direction. If the collet nut is tightened when the edge is not firmly in thegroove, the collet chuck may stay stuck in the collet holder, making it impossible toremove the collet chuck.
• Clean the collet holder and collet nut and collet chuck before inserting a millingbur. Fixing a milling bur while chips are present on the collet holder and collet nut
and collet chuck may cause bur runout and affect milling accuracy.

3. Gently screw the collet chuck and collet nut into the collet holder with your fingers.
Note: Do not screw the collet chuck and collet nut all the way in (see Figure 6).

4. Insert the milling bur in the milling bur holder, letting it protrude by between 25
and 35 millimeters, measured from the tool tip to the collet nut’s face. Sliding thecap down to make contact with the collet nut’s face and to adjust the bur so that its
tip can be seen in the cap window will ensure the bur protrudes by between 25 and35 millimeters (see Figure 7).

5. Finish tightening the collet chuck and collet nut in the collet holder using the two
included spanners. The recommended tightening torque is 7 N・m. Use the 14-mm
spanner on the collet nut and the 12-mm wrench on the collet holder. Turn in aclockwise direction to fasten the milling bur (see Figure 8).
Caution• If the tightening torque is too loose, it may cause milling defects or broken millingburs.
• If the milling bur protrudes by less than 25 millimeters, the spindle may contact
the swivel table and cause damage to the milling machine.
• If the milling bur protrudes by more than 35 millimeters, it will lead to milling
defects or a broken milling bur.

6. To remove the milling bur, position the wrench on the collet nut and turn in acounterclockwise direction. This will loosen the collet chuck so you can remove themilling bur. During much of the first rotation of the collet nut, the collet nut andcollet chuck will tighten for a moment, but continuing to turn the collet nut will open
the collet chuck.
7. To remove the collet chuck, grip the collet nut in your hand, angle the collet chuck
down in the direction of the wrench flat, and slide the collet chuck out. If the collet
chuck does not come out, angle it again toward the wrench flat on the collet nut (seeFigure 4).

32 Method 2 for fixing and removing milling burs (i.e., using the milling bur replacement
jig)
Follow Steps 1 through 4 given in Method 1.
5.

Place the milling bur replacement jig on a table and insert the milling bur holder.
Firmly hold the milling bur replacement jig down with your hand on the section
shown in gray in the diagram below while turning the wrench down toward thetable (in the direction indicated by the arrow) and finish tightening the milling bur.
The recommended tightening torque is 7 N・m (see Figure 9).

2.10 Attaching and Removing the Disk Fixing Plate
The disk fixing plate is used while attached to the swivel table. Disks can be fixed andremoved when the disk fixing plate is removed from the swivel table. Therefore, if you
have two or more disk fixing plates (extra fixing plates are available as an option), it ispossible to fix or remove disks on other disk fixing plates while milling another disk.
1. Clean the disk fixing plate and Mounting plate, indicated by the rectangle in the
diagram below with dry cloth.
Triangular arrows

CautionIf milling chips remain in the screw holes, the screws may not provide the proper
clamping force. In particular, the screw holes in the disk fixing plate may bedamaged if they are not cleaned properly.
2. Place the disk fixing plate on the swivel table’s mounting plate. Fit the location
holes on the back of the disk fixing plate with the positioning pins on the mounting
plate. The back of the disk fixing plate has one round location hole and one ovallocation hole. Following the diagram below, the round location hole is underneaththe arrow on the left side. (Match the triangular arrows on the mounting plate andthe disk fixing plate when placing the plate on the mounting plate.)

Important• Attach the disk fixing plate so the round location hole is on the left side.
• Do not remove anything from the milling machine other than the disk fixing plate.
Loosening or removing the mounting plate or other screws may interfere withproper milling operations.
37• Take care not to knock the disk fixing plate while attaching it to the swivel table,
as it may affect the finish of the workpiece.
• When attaching a disc on the disc fixing plate, Use the included torquescrewdriver (0.3 N•m) and bit (3 mm width) to fix (retighten) the hexagon bolts
from (1) to (4). Otherwise it will result defective processing because of the moveof the disc fixing plate by the loosen hexagon bolts.
Caution• Clean the screw holes in the mounting plate after use. If milling chips become•

lodged in screw holes, it may not be possible to tighten the screws the next time
the plate is used.
When using the Hexagon bolt, insert the bit straight into the hexagon bolt. If you
use it at an angle, the hexagon bolt may wear.

Note
To remove the disk fixing plate, position the bit of the included torque screwdriver(0.3 N•m) in the head of the hexagon bolt and turn the torque screwdriver in acounterclockwise direction. In this way, remove all four bolts.

38

2.11 Fixing Disk
Place a disk on the disk fixing plate and then place the disk clamp plate over the disk.
Use the included torque screwdriver (0.3 N•m) and bit (3 mm width) to fasten down thedisk clamp plate with four hexagon bolts. Tighten bolts in opposite corners first, like theorder (1) through (4) shown in the diagram below. You may tighten the bolts in any
order, as long as bolts in opposite corners are tightened first.
