5.3 Compressed air connection

The SFS 300P spindle requires a compressed air connection. This compressed air connection must supply 6.5 – 7 bar (94.27 – 101.5 psi) during non-stop operation. The spindle with automatic tool change requires the compressed air in order to activate the pneumatic collet. Furthermore, sealing air is required to prevent foreign objects from entering the spindle. The air consumption of the machine is 80 l/min.
The delivery form of your machine also contains a maintenance unit for the compressed air supply. The incoming pressure for the machine can be regulated at the maintenance unit. The built-in water separator with a filter cartridge should prevent air contaminated with humidity or dirt particles from entering the machine.
The incoming compressed air must be dry and oil-free according to ISO 8573-1, since the water separator can only filter out minor residual quantities. Compressed air that does not meet these requirements may lead to failure of the bearings and electrical damage to the spindle.

Air purity according to ISO 8573-1:

Solid matter particles Water Total oil content

Class 3 Class 4 Class 3

Filter rate better than 5 µm for solid matters Maximum pressure condensation point + 3°C Maximum oil content 1 mg/m³

5.4 Connecting the maintenance unit
The maintenance unit can either be mounted to the housing or directly connected to the compressed air supply. For the choice of mounting, it is important to consider that the maintenance unit must be clearly visible during daily operation to enable regular inspection. The following text describes the mounting of the maintenance unit to the housing. Please observe the steps M3. to M5. for connecting the maintenance unit directly to the compressed air supply.

The maintenance unit must always be installed upright. If this is not done, the function of the water separator cannot be ensured.

M1.

Remove the two blind screws below the air vents on the side panel of

the milling machine.

M2.

Attach the maintenance unit in an upright position using the cylinder-

head screws supplied.

Operating the machine

7.1 Introduction to the operation
Once you have made sure that all cables and hoses are correctly connected, you can switch on the machine by means of the master switch at the rear of the machine. For a milling job, you only need the discs you want to use, as well as the corresponding tools. As the machine is operated via the software, all the additional information regarding the operation of the machine can be found in the software manual. The machine is equipped with a safety contact and safety interlock at the front flap. Given the safety interlock, the front flap cannot be opened during the milling procedure.
The machine may only be operated if the safety interlock is activated.
7.2 Extraction system
You can find all information regarding the operation, installation and maintenance of the extraction system in the corresponding operating instructions. Improper handling or use for purposes other than intended may detrimentally affect the safe operation of the system.
Operate the machine only with the extraction system switched on and make sure that the connection of the extraction system is not obstructed. Otherwise, flying shavings may reach sensitive parts of the machine, such as bearings or ball screws, and cause damage! It is imperative to set the extraction system to the maximum level for operation.
The machine is equipped with a negative pressure sensor to measure the extraction output. Make sure that the extraction system is switched on and that the connection of the extraction system is not obstructed. The integrated sealing air concept of the work chamber prevents dust and shavings from entering the mechanical and electronic components of the machine and thus reduces wear and maintenance efforts.

25

7.3 SFS 300P synchronous spindle
For the operation, installation and maintenance of the spindle, the provisions of occupational safety apply. Improper handling or use for purposes other than the ones intended considerably compromise the safety during operation!
The SFS 300P synchronous spindle is a precision component, which must not be subject to the use of force, e.g. striking! Remember that the submersion depth and travel speed must not be too high during processing. This may result in the work pattern being ripped out and the tool getting jammed, which may cause irreparable damage to the machine and/or the spindle. For optimum milling results, use the milling strategies provided in Zenotec CAM from Wieland Dental + Technik. If other or modified milling strategies are used, Wieland Dental + Technik will not accept any liability. Do not use tools with a large unbalance (single-blade cutters, gravers) in combination with a high spindle speed. The unbalance puts very high strain on the ball bearings, which may cause damage to the bearings.
Please note that wet grinding will reduce the service life of the spindle due to the harder materials processed and the higher spindle speed.

7.4 Tools
The tools for the individual materials are predefined in the CNC software (see chapter 8.1.6 and 8.2.2 ).
For operation, it is imperative that the corresponding tools are inserted in the respective, defined slots.
In addition to the standard cutters, what is known as sister tools can be inserted into the tool holder as an option. If a standard tool has reached its wear limit, the corresponding sister tool is automatically used for further milling.

7.7 Procedure in case of a power failure (Zenotec select hybrid with material changer)
If a short power failure occurs while the material changer is not in use, it is sufficient to just switch on the machine again.
If a power failure occurs during processing, however, follow the instructions of the software to enable referencing of the machine. In case of a prolonged power failure or a defect in the power line, you can deactivate the safety interlock with the emergency key to remove the disc from the machine.
If the power supply is interrupted while the material changer is in use, it is not sufficient to just switch on the machine again. In such a case, the disc changer would trigger an emergency-off signal before the referencing of the machine. This is a safety feature to prevent damage to the machine.

If the machine fails while the material changer is in use, the following steps are required to bring the machine back to its home position.
1. Switch off the machine using the master switch and
disconnect the machine from the power supply.
2. Set the pressure at the maintenance unit to 0 bar/psi or
disconnect the compressed air line from the main line.
3. Open the front flap of the material changer.
4. Insert the key for the emergency-release of the front flap into
the opening on the right of the material changer LED.
5. Deactivate the safety interlock of the front flap by turning the
key in an anti-clock-wise direction until it stops.
The front flap of the working chamber can now be opened.
6. Open the front flap of the working chamber.
7. Open the gripper and remove the disc holder, provided it is
not locked in place in the milling chamber (see Figure 13).

Contact your Service Centre. The corresponding addresses can be found in the jacket.

50

9.2 Cleaning of the interior (working chamber, disc holder, measuring sensor, material changer)
Never use compressed air to clean the interior, since this may result in shavings reaching sensitive components, such as the linear guides or the spindle bearings. Clean the machine regularly to prevent dirt or shavings from accumulating in the guide rails and other sensitive machine components. Use only a vacuum cleaner and brush for cleaning.
If you only use a brush for cleaning, switch on the extraction system in the software so that the shavings are immediately removed.
Cleaning of the working chamber and disc holders Make sure that you remove all material residues in the working chamber with the brush and/or vacuum cleaner.
Cleaning of the measuring sensor The measuring sensor should be separately cleaned using a brush to remove all contaminants.

Cleaning of the material changer (only Zenotec select hybrid with material changer)
To clean the material changer, remove all the disc holders from the machine and clean them. Clean the interior of the material changer using a vacuum cleaner and a moist cloth. The release slide is best reached by lifting the slide flap from the working chamber.
Use the cleaning function in the software for that purpose.

51

9.3 Cleaning the spindle / collet
Only use the original spindle maintenance set for cleaning the spindle or the collet chuck.

Figure 17: Spindle maintenance set
Cleaning of the collet is described in detail in the Instructions for Use of the Maintenance Kit.
Never use compressed air to clean the spindle, as this will damage the bearings of the spindle.
Clean the collet once a week as follows: 1. Click the button “Remove tool” in the CNC module of the software. 2. Confirm the prompt to open the collet. 3. Open the front flap. 4. Manually unscrew the collet using the knurled screw of the Spindle Maintenance Kit.
Make sure that a measuring pin is in place while unscrewing the collet to avoid a deformation of the collet.
5. Clean the inner cone of the spindle with the cleaning cone of the Maintenance Kit. 6. Clean the collet using the brush of the Maintenance Kit and make sure that the sealings in the collet do not
fall off. 7. Take a small quantity of the collet grease from the Maintenance Kit and apply it on the slopes of the collet. Make sure that no grease enters the longitudinal slots and the interior of the collet and use only the collet grease supplied with the Maintenance Kit to avoid damaging the spindle.

52

8. Screw the collet into the spindle until it stops using the screw-in piece. Make sure that a measuring pin is in place while screwing the collet into the spindle to avoid a deformation of the collet.
9. Click the button “Basic settings”.
9.4 Cleaning of the exterior (housing)
Basically, powder-coated surfaces should be cleaned with a soft, dry cloth in a first step. If any contamination cannot be removed in this way, the cloth may also be moistened. If necessary, a cleaning agent with a neutral pH may be used.
Basically, contact of alkaline or acidic substances with the powder coating must be prevented. Metallic powder coating is particularly sensitive. During cleaning, particular attention should be paid to the stick-on label to make sure that it is not peeled off. The adhesive letters are particularly sensitive to friction and strong cleaning agents.
9.5 Compressed air maintenance
Check on a weekly basis if water has accumulated in the water separator and empty the container, if necessary, by opening the discharging screw (see Figure 4 on Page 21). The condensate is then blown out under pressure. Condensate in the separator usually indicates that the compressed air is insufficiently dry. In this context, please observe our requirements regarding air purity in chapter 5. In case of severe contamination, the filter cartridge in the water separator must be cleaned or replaced. A severely contaminated cartridge may lead to a decline in the compressed air output.

53

1. Disconnect the machine from the compressed air supply. 2. Unscrew the bowl of the water separator. 3. Unscrew the filter screw below the filter cartridge. 4. Pull out the filter cartridge. 5. Check the filter cartridge, clean it or replace it, if necessary. 6. Insert the new or cleaned filter cartridge.

If the compressed air meets the purity requirements of ISO 8573-1, the filter cartridge usually does not have to be replaced. If the filter cartridge is contaminated, please check the purity level of your compressed air.
9.6 Calibration
The machine is supplied in a calibrated condition. As long as your milling results are impeccable, renewed calibration is not necessary. If inaccuracies occur, however, calibration is required. In case of a problem, please consult a service technician before you recalibrate the machine. Calibration is time- consuming and may lead to poorer milling results if performed incorrectly. Therefore, check the operating conditions first. Check the fixation of the work pattern, the condition of the tool and the material to be processed before you execute a calibration procedure. Details on conducting the calibration procedure can be found in the Software Manual.
9.7 Machine maintenance (by Wieland Dental + Technik Service)
Wieland Dental + Technik recommends having a service technician regularly perform maintenance on the machine. Machine maintenance should be conducted at least once a year.

The connecting hose must not be allowed to sag, as this will result in liquid accumulating in the hose and thus reduce the suction performance.
13.6.1 Length of the connecting hose Connect the connecting hose with the suction opening of the Zenotec select hybrid and hold the hose to the hookup for the connecting hose at the Zenotec hydro for verification. Check if the hose sags. If it does, shorten the connecting hose. 13.6.2 Shortening the connecting hose Only if the connecting hose sags!
Mark the area where the connecting hose reaches the hookup at the Zenotec hydro. Add approximately 3 cm excess length. Cut the connecting hose at the marked area using a sharp knife. Connect the connecting hose with the Zenotec hydro. 13.6.3 Securing the connecting hose at the Zenotec hydro Loosen the screw-type hose connection of the Zenotec hydro. Push the connecting hose through the screw-type hose connection with a distance of approximately 3 cm. Make sure that the black sealing ring does not fall off.

Hold the connecting hose in place with one hand and tighten the screw-type hose connection with the other hand.

13.6.4 Filling in Synergy 905 Make sure that the Zenotec hydro is disconnected from the power supply when filling the liquid container.
1. Remove the module insert. 2. Fill the liquid container (max. capacity 22 litres) with 1.5 litres of Synergy 905 and 20.5 litres of tap water. 3. You now have 22 litres of an emulsion consisting of lubricating coolant and water (7% solution). 4. Replace the module insert. 5. Connect the power pack with Zenotec select hybrid and the power supply. 6. Zenotec hydro is now ready for operation.
13.6.5 Refilling Loss of water must be expected during milling.
Regularly check the liquid level of the Zenotec hydro. Make sure to observe the indications on the display in this context.
Generally, the liquid container is topped up with pure water. When topping up while the extraction system is running, the water can also be filled directly into the milling chamber.
You may top up the liquid container with water until you are reminded by the Zenotec CNC software that the filter needs to be replaced.

Operating Zenotec hydro

14.1 Switching from dry operation to wet operation
Before every wet-grinding procedure, make sure that Zenotec hydro is ready for operation. Operate the Zenotec hydro always with the Zenotec cyclon switched on to prevent damage to the machines.
When switching the operation mode, follow the workflow of the Zenotec CNC software.
14.1.1 Zenotec select hybrid without material changer Remove the disc holder from the milling chamber. Clean the entire milling chamber of the Zenotec select hybrid with a vacuum cleaner and a brush, if necessary. Ensure that there is no dust left in the milling chamber after cleaning.
Remove the suction hose from the Zenotec select hybrid. Attach the suction hose to the connection of the Zenotec hydro intended for this purpose. Connect the Zenotec hydro connecting hose with the Zenotec select hybrid. Empty the dust drawer of the Zenotec cyclon.
