OPERATIONS
★Please follow up steps 1.2.3.4. to set up the end mill to the collet
holder.(without tightening)
1. Determine diameter and ute of your end mill, and then select the
proper collet and collet holder.
2. Insert collet into collet holder and tighten nut slightly.
3. Insert end mill into collet holder and juts out 35mm or so from the
collet holder.
4. Find out the flute with edge over center point and have it to be
parallel with the benchmark notch.
★Set alignment knob to the prpoer number according to the diameter of the
end mill. (e.g. End mill dia. 10mm, set the scale to 10.)

★The flute with edge over center point should be parallel with the benchmark
line.
1. Pointing holder's benchmark notch at triangle mark of alignment
base and insert it to the base.
2. Loosen holder, lower the holder to the base, and screw the nut
clockwise. At the same time, rotate the ute with edge over center
point clockwise until it touches the alignment block.
3. Tighten the ER nut until the end mill is supported but free to turn.
Pull out the holder counterclockwise, tighten up the holder after
confirmed the flute is parallel with the notch. If it's not parallel,
please repeat the alignment steps.the benchmark notch.
1. Switch on machine.
2. Pointing ER holder at the notch of primary edge re-sharpening
port NO.1.
3. Insert the holder into the port NO.1 with a slight push motion for
grinding.
4. Change to another flute, repeat the above steps until the
sharpening for all utes' edges is complete.

ERelief settings
HEnd gash sharpoening
1. If the relief needs to be adjust, please use provided 4mm hex
wrench to loosen the screws in the sharpening NO.1.
2. Rotate clockwise ( ) to increase, rotate counterclockwise ( ) to
decrease. Tighten after relief setting.
1. Pointing ER holder at upper screw of end gash sharpening port
NO.3, insert it into the port with a slight push motion. For precise
and average grinding, hold tight the upper part of the ER holder
with one hand and move the lower port at both sides with another
hand to sharpen until grinding noise disappear.
2. Take out the holder with end mill and change to another flute,
repeat the above steps until the sharpening for all flutes' end
gashes is complete.
3. Take out the end mill from the holder and inspect it.
FSecondary clearance angle sharpening-1 (for 4 ute)
1. Pointing ER holder at screw secondary clearance andle
sharpening port NO.2, insert it into the port with a slight push
motion to sharpen until grinding noise disappear.
2. Change to another flute, repeat the above step until the above
steps until the sharpening for all flutes' edges is complete.

Secondary clearance angle sharpening-2 (for 2 and 3
ute)
1. If you need to sharpen the secondary clearnce angle completely,
loosen the screws in the screws in the secondary clearance angle
port, and then rotate left and right repeatedly for clearance.
Attn: the rotate ranges for 2 ute and 3 ute are different. For 2 ute,
rotate the holder left and right in whole rotation; for 3 ute, on the
sharpeening port NO.2, and rotate the benchmark notch side only.
2.To sum up, the grinding should start from the ute pointed at the
benchmark notch.

REPLACING THE WHEEL
Caution
ARemoving the wheel cover
1. Unplug the machine.
2. Loosen the three screws in the wheel cover counterclockwise with
4mm Allen key.
BCleaning the grinding dust
1. Make sure the temperature of the wheel goes down to normal
temperature.
2. Open the upper cover, clean the grinding dust with pressurized air
and wipe outside with dry cloth.
CRemoving the washer
1. Hold the wheel with left hand and loosen the screw
counterclockwise with 4mm Allen key with right hand.
2. Take out the black washer.
3. Take out the wheel from the motor hub slightly.
DReplacing the wheel
1. Take a new proper wheel.
2. To re-install the wheel, reverse steps taken to remove wheel.
★ The motor hub is very precise, it will be damaged by excessive
force and affect the position of wheel acccordingly.
1. Determine the material of end mill before grinding. Please use SDC diamond wheel for carbide end mill ; please use CBN
diamond wheel for HSS end mill.
2. Determine the ute of the end mill and use the proper collet holder; PF-313 / 1225 is suitable for 2, 3, and 4 ute end mill.
3. Aligning end mill is the most important among the steps, make sure to complete this step before grinding.
4.This machine is guaranteed for one year under normal operating (expendable parts and wheels are exceptions), please inform
the serial no. when the machine need to be repaired.
5. For end mill 4~6mm, be sure with very slight push motion while grinding the primary edge due the outer diameter of wheel is
smaller.
6. The motor cannot run continuously over 1 hour.

AProcedures for changing the grinding wheel
1. Choose the collect accordingly to the drill diameter.
2. Slot the chosen collet Holder (B) at an appropriate angle.
3. Insert the drill into the connected collet and collet holder set, leave a 35mm extension
of the drill’s original body length, but do not tightened the drill too tight.
4. Connect the Collet Nut (A) to the unit of Collet (C) which is locked to the Collet holder
(B), and tighten the set, yet make aure the drill is not rmly tightened, but still able to
be tumed.
5. Complete the above steps, so the Collet Chuck Set (H) is ready for drilling.
B
Setting the drill length and position its movement for
drilling
1. Reset the Scale Ring (C1): tum the ring all the way clockwise, and then turn it anti-
clockwise to the required drilling size indicated on C1.
2. Insert Collet Chuck Set (see 1) into Preset Length Bracket (C2) and make sure the pin
is locked to the slot.
3. Turn the Collet Chuck Set clockwise until it touches against the pin (see 2), and turn
the drill clockwise till it touches against the drill cutting edge.
4. Screw the ER Collet Holser (see 3) clockwise to tighten the drill.
5. Take out the Collet Chuck Set to check if the drill cutting edge is parallel to the slot of
ER clamping nut. If it’s not parallel, please repeat the above steps.
6.Attention: For used drill, with less than 3/4 (three quarters) of its original length left, it is
advisable to adiust the 1~2mm scale up on the Scale Ring.
CPoint Angle Grinding for Drill
1. Insert the Collet Chuck Ser into Point Angle Bracket (see 1), and set the slot into the
pin.
2. Make the Collet Chuck Set touching the wheel lightly (see 2 ), turn clockwise and
reverse until the grinding sound disappears.
3. Take out the Collet Chuck Set, rotate it 180 degree, and repeat Step 1 and 2 to nish
the grinding for the two drill chisel edge angles.
DCenter Poinr Trimming Grinding for Drill
1. Insert Collet Chuck Ser (see 1) into the grinding unit and insert the slot into the pin (see
2).
2. Place Collet Chuck Set (see 1) upright and insert it into the top bracket to lightly touch
the wheel. Turn it clockwise and reverse until grinding noise disappears.
3. Take out Collet Chuck Set, rotate it 180 degree and repeat Step 1 and 2 to nish up
the grinding.
EAdjustment for Trimming Angle
1. To obtain a larger trimming angle-turn the F1 Screw anti-clockwise ( ),( ).
