1 Control of IBAG-Periphery
新加坡私立院校1.1 Introductions
This manual is designed for programmers and designer who should t up an IBAG spindle.
It contents information’s how control und supervision should be realid. It does not content any information’s about maintenance or using of the spindle unit. The programmer/designer has to know the local laws and rules for using HSC-spindles and he is responsible to convert tho
rules into the real application. It is machine-tool-builder’s obligation to make a risk-analysis for the machine tool together with an IBAG-spindle and to realize the safety-modification
necessary. IBAG does not take any responsibility in ca of damage or accident’s caud by wrong using of the spindle or of its periphery. In ca of any question do not hesitate to contact our rvice department.
1.2 Lubrication
This chapter is not important if your spindle has grea-lubrication (Option “P”).
1.2.1 Design of lubrication
The dosage-unit can be connected directly to the oil-system, if you have a single-spindle unit. If there is more than one spindle running on the same lubrication-system, the lubrication has to be switchable for every single spindle. Put valves between the oil- and the air tubes. After each
valve has to be put a pressure-switch to supervi the function of the valves. Make sure, the
valve you are going to u is allowed for the working-pressure. Sometimes are air-valves with p. pre-control necessary.
1.2.2 Control of lubrication-system (IBAG-Amolub)
Pre-lubrication
The lubrication should run for 2 [min] after switch-on of the machine to make sure, the oil has reached the spindle oil-entry. The valves, if there are any in the oil- and air-tubes, has to be
basics
switched on during pre-lubrication. Oil and air supplied to the spindle has to be switched at the same time!!
小升初个人简历Lubrication, if spindle is running
The spindle has to be lubricated, if the spindle is running. Switch the lubrication-system, oil- and air valve on while the spindle is not in standstill.
Supervision of air pressure of lubrication
面裂The air pressure is normally monitored at the air-filter-unit, or if there is a valve between air-unit and spindle, after the valve. It is recommended generally to put the air-pressure-switch as clo as possible to the spindle. If there are feed-trough or other critical parts, the pressure-switch has to be mounted after tho components.
hun
Shut off of lubrication after spindle stop
The lubrication has to be kept on for another 3 [min] after the spindle has been stopped (speed zero). If the spindle has not been started during this time, the lubrication can be switched off.
The lubrication needs to be switched on immediately when the spindle has been started again.
Monitoring of oil-pressure of lubrication
The IBAG Amolub-system consist internal oil-pressure supervision. For single-spindle-
application is this supervision sufficient. Are there valves in the oil-tubes, an oil-pressure-switch has to be mounted after the valve. If the oil-system is powered on, it delivers every 3 [min] a
lubrication impul of approx. 7-12 [s]. The monitoring must be able to detect loss of
lubrication impuls. The pressure-switch should be t to approx. 18 [bar].
Supervision of lubrication-system
The IBAG Amolub-system does have internal pressure- and oil-level supervision. If this signal disappears, the spindle has to be stopped immediately.
1.3 Supervision of cooling-system
The cooling-system must make sure, the spindle is supplied with cooling-water with a
temperature between 25 [°C] and 28 [°C]. There are normally flow-switch mounted in the return-tube of the cooling-system, to be sure, the spindle is supplied with water. An additional
supervision for over temperature, t to 35 [°C] is recommendable. Other supervision are

allowed, if they can make sure, the spindle is cooled enough.
1.4 Air-Conditioning of switch-cabinet
All electrical components, which are not mounted in the spindle, are built for an environment-temperature between 15 and 40 [°C]. Switch cabinet has to be cooled, if necessary.
1.5 Control of tool-changer
Tool-change is allowed in standstill only. U the signal “speed zero” from the drive to make
sure, the spindle is in standstill. Make some additional delay of 1..2 [s] after getting the
“frequency zero”-command from an open-loop-converter to be sure, the spindle is really in
standstill. It is recommendable to interlock the tool-changer if the drive has tripped becau
some drive do not provide the right signal if they have tripped. If the tool change is active, the start-signal has to be locked to be sure, the spindle cannot be started.
Mount a 5/2-way or 4/2-way-valve to the TI/TO-tubes on pneumatic tool changer to switch them, where the pressure-less tubes is ventilated.
The TI-connection on hydraulic tool changers (option …H“) can be pressured permanently with
6 [bar]. The tool can be relead by hydraulic pressure. You’ll find the necessary releasing-
pressure in the datasheet provided with the spindle. Make sure, that the oil can flow back into the tank without any considerable resistance in the tubes, if the tool changer is not pressured.
Before you start the spindle the first time, make sure, the rotor shaft is rotating free without any resistance. If something is making any resistance, plea check the lines TI and TO again.
1.6 ATC-Sensors
The ATC-nsors check the position of the drawbar.

Remarks:
Tho are the standard-signals of IBAG-spindles. On special-version, this signal can vary.
Details can be found in the instruction-manual to the spindle. During tool change, some
undefined conditions can appear. Wait approx. 1 [s] after operation before you check the ATC-
signals to avoid wrong alarm-messages. The signal TI should be delayed for approx. 0.2 [s]
before the spindle is started again, to avoid touching of tool changer-piston on the drawbar. An
add. safety can be installed if a pressure-switch is mounted into the hydraulic-line. The TO-
condition is fulfilled, if the nsor TO and the pressure-switch appear.
1.7 Air pressure-Switch Tool changer
The air pressure-switch for the tool changer is normally mounted on the filter-unit. Set point is
5.5 [bar], even on hydr. spindles.
1.8 Control of aling-air (AS)
Switch on the aling-air together with the machine. If the spindle is built in in over-head
position, the AS has to kept on a certain time after switch off of the machine, until no water or
commercially
dirt can go into the spindle.
1.9 Air-pressure-switch aling air (AS)
Air-pressure-switch for the aling-air is normally mounted on the filter-unit. If a different switch
already monitors a higher pressure, the pressure-switch for the aling-air is not necessary

1.10 Spindle-Start
Spindle-Start is allowed only, if all supervision signali operation without fault and all safety-
devices are installed and working correctly. The ATC-signal has to be interlocked while the
spindle is running.
