3 ToolDescription,Specications
3.1 Intended Use
The tool is intended to be used in a CNC milling machine or in a machining centre with HSK or SK tool
holder. Use the tool only on machines that are in a proper technical state.
A coolant lubricant emulsion or compressed air are provided for as coolant for internal cooling.
The PF3000 is suited for machining non-ferrous metals, such as aluminium, aluminium alloys, copper,
brass and bronze. Further materials or tool holders on request. Since only optical measurement is
allowed for tools with CBN tips, you must ensure that an optical measuring / adjusting unit is available.
3.2 Improper Use
The tool is not suited for machining ferrous metals (steel and cast iron). Besides, the tool is not suited
for MQL (minimum quantity lubrication).
It is not possible to guarantee the proper functioning of the tool if it is used in a machine or with a ma-
terial for which it is not suited. We cannot be held liable for any consequential damage to the machine
or the workpiece.

5.1 Initial Safety Notes
Important information for your safety
Youareresponsible!
Always take note and observe the safety instructions in the document "General Safety Instructions"
and the locally valid safety instructions.

5.2 Important Information on the Hexagon Wrenches
CAUTION
Risk of injury due to hexagon wrenches of inferior quality
Hexagon wrenches of inferior quality can break or bend during assembly of the
PF3000 due to the high tightening torques applied. You can get injured by this.
Only use high-quality hexagon wrenches for assembly.
Use the adapter (accessories) for assembly.
We recommend the use of the adapter (accessories) for assembly of the PF3000.
5.3 Designationofindividualparts
Tohaveacleardenitionoftheindividualparts,weusethefollowingexplodedviewstodesignate
them:

1 GÜHROJET milling head
holder
3 Ball-ended thrust
screw
5 PCD cartridges
2 Base body (from Ø 160 mm
with pre-assembled coolant
distribution plate)
4 Clamping screw 6 Coolant distribution screw
Ø 125 mm / cheese head
screws from Ø 160 mm

5.4 Assembly of the ball-ended thrust screws
The ball-ended thrust screws are already assembled on delivery. When you have checked that the
ball-ended thrust screws are not protruding into the cartridge seat, you can proceed with Chapter 5.5.
"Assembly of cartridges".
Proceed as described below if you want to replace the ball-ended thrust screws.
Requirements:
;Assembly paste Weicon, anti-seize
;Base body PF 3000
;Ball-ended thrust screws
;Hexagon socket wrench (AF 2)
1. Grease the ball-ended thrust screw with the assembly paste. This ensures that the adjustment can
be made smoothly.
2. Screw the ball-ended thrust screw (1) with the hexagon socket wrench into the base body (2).

10
The ball-ended thrust screw may not protrude into the cartridge seat (3) so that the cartridge can
be mounted in the bottommost position.
3. Assemble the remaining ball-ended thrust screws in the same manner.
The ball-ended thrust screws are assembled.

11
5.5 Assembly of the Cartridges
Use the following procedure to install the cartridges
Requirements:
;Assembly paste Molykote, G-N Plus
;Base body PF 3000
;Cutting cartridges
;Washer
;Clamping screws
;Torx wrench T20
1. Insert the cartridge (2) in the bottommost position in the base body (1).
2. Grease the thread of the ball-ended thrust screw with the assembly paste.

12
3. Secure the cartridge with the washer (4) and the clamping screw (3). Use a Torx wrench T20 for
this.
The cartridge is secured.
4. Repeat these steps for all other cartridges.
The cartridges are assembled.
From here, the completely assembled base body is called a shell type milling cutter.

5.6 InstallingtheShellTypeMillingCuttersonaGÜHROJETMillingHeadHolder
Use the following procedure to install the shell type milling cutters on the GÜHROJET milling head
holder:
Requirements:
;GÜHROJET milling head holder
;Shell type milling cutter (chapter 5.4 and 5.5 must have been completed)
;Coolant distribution screw up to Ø 125 mm / 4x cheese head screws from Ø 160 mm
;Torque wrench, for example part no. 4915 with matching internal hexagon socket wrench
1. On delivery, the GÜHROJET milling head holder has a balance quality of
G6.3/15,000rpm(static).Whenusingadi󰀨erentmillingheadholder,pleasemakesurethatitalso
has a balance quality of G6.3 / 15,000 rpm. Where necessary, the shell type milling cutter has to be
balanced before it is installed.
2. Secure the GÜHROJET milling head holder in a tool mounting block (e.g. part no. 4946). The next
assembly steps may not be performed in the spindle of setting or measuring machines.
3. Push the shell type milling cutter onto the GÜHROJET milling head holder. Pay attention to the
position of grooves and driving keys (2).

14
4. With a tool diameter up to Ø 125 mm: Screw the two parts together with the coolant distribution
screw (3). Use a torque wrench with matching internal hexagon socket wrench.Observe the tight-
eningtorquesintable3"Torquespecications"onthefollowingpage.
With a tool diameter from Ø 160 mm: The coolant distribution plate is already installed in the shell
type milling cutter. Push the shell type milling cutter (4) onto the GÜHROJET milling head holder
(3). Screw the two parts together with the 4 coolant distribution screws (5). Use a torque wrench
with matching internal hexagon socket wrench.Observe the tightening torques in table 3 "Torque
specications"onthefollowingpage.

5.7 Setting the Cartridges
Use the following procedure to set the cartridges:
Requirements:
;Ball-ended thrust screws installed (chapter 5.4)
;Hexagon socket wrench AF2
;Cutting cartridges installed (chapter 5.5)
;Shell type milling cutter installed on milling head holder (chapter 5.6)
;Torque wrench, for example part no. 4915 with Torx T20 socket wrench
1. For all cartridges in their lowest axial position: Apply the clamping screw with approx. 1 Nm with the
torque wrench
2. Set all cartridges to 0.02 to 0.03 mm short of the setting dimension with the hexagon socket wrench
To do this, turn the ball-ended thrust screw (1) clockwise. Details of the setting dimension can be
referenced in the enclosed tool drawing.

16
3. Tighten all clamping screws (2) to 7 Nm with the torque wrench.
4. Set all cartridges to the setting dimension. Axial run-out may not exceed 0.002 mm.
5. Record your settings.
The cartridges are set.

17
5.8 BalancingtheFullyAssembledTool
Once the settings have been completed, the entire milling system has to be balanced by means of the
balancing screws provided.
Requirement
;The work described in chapters 5.1 - 5.7 has been carried out
1. Balance the tool to a balance quality of G6.3 / 15,000 rpm (static). Use the balancing screws (1) to
do so. Other balance quality are available on request.
The tool is ready for use and can now be installed in the machine tool.
