• Specifications for the portal interface (PV interface)

Emissions

The values stated are emission levels. Although there is a correlation between emission and imission level, it cannot be reliably derived from this whether additional precautions are necessary. Factors influencing the current immission level existing at the workplace comprise the duration of exposure, the room characteristic, other sources of noise, etc. such as e.g. the number of machines and other adjacent machining operations. In addition, the permissible immission level may differ from country to country. This information is nevertheless suitable for providing the machine user with an improved assessment of the hazard and risk.

Noise emission specifications

Noise emission values determined according to DIN EN ISO 3744:

Sound pressure level L PA = 71 dB (A)
Uncertainty K PA = 3 dB (A)
Sound power level L PA = 82 dB (A)
Uncertainty KPA = 3 dB (A)

The noise measurement was done without tool at idling speed.

Use according to intended purpose

• The milling motor is intended for permanent installation in guiding portal systems with ø 43 mm clamping collar.

• The milling motor with quick tool clamping can be flanged directly to a portal system using six screws (M6 thread) according to the specifications of the portal system (Fig. 5).
  

• The milling motor is not designed for continuous industrial operation.

• The milling motor is considered an incomplete machine. The milling motor may only be commissioned once it has been determined that the portal system into which the milling motor is to be incorporated complies with the provisions of the current and valid Machinery Directive. Please also note the corresponding warranty conditions for the milling motor and any supplementary appliances.

GRAPHE

Residual risks

Danger
Even if used in accordance with its intended purpose and despite conforming with the safety instructions, residual risks caused by the intended use that can lead to health consequences will always remain.

• Breakage of the rotating tool.
• Breakage of the tools and risk of the tools or parts of them being hurled away.
• Touching live parts with the housing open and the mains plug not removed.
• Hearing can be impaired when working for long periods without ear protectors.
• Emission of hazardous or potentially explosive dusts (all types) during longer lasting operation without extraction. Please note the safety data sheet of the material to be machined.

Safety instructions

Danger
Always observe the following safety instructions and the safety regulations applicable in the respective country of use!

General instructions:

• Children and adolescents must not operate this machine. This rule does not apply to young persons receiving training and being supervised by an expert.
• Never work without the guards of the portal system into which the power tool is inserted and that are prescribed for each operation. Do not make any changes to the portal system and the milling motor that could compromise safety.
• Damaged cables or plugs must be immediately replaced. Replacement may only be carried out by Mafell or an authorised MAFELL service workshop in order to avoid safety hazards.
• Avoid sharp bends in the cable. Do not wind the cable around the milling motor especially when transporting and storing the milling motor.
• The use of the power tool with water or conductive liquids is prohibited.
• We exclude the use as hand-guided milling motor.
• Keep the milling motor away from rain or moisture. The penetration of water into the milling motor increases the risk of electric shock.

Do not use:

• Damaged tools or tools that have changed their shape.
• Blunt tools due to the excessive motor load.
• Tools that are not suitable for the milling motor speed during idling.

Instructions on the use of personal protective equipment:

• Always where a dust mark during work.
• Always wear protective goggles during work.

Instructions on operation:

• Do not reach with your hands into the danger zone of the tool.
• Examine the workpiece for foreign objects.
• Monitor the speed. If an uncontrolled speed increase or speed jump occurs, the power supply must be switched off immediately

Instructions on service and maintenance:

• Regular cleaning of the milling motor is an important safety factor.
• Only original MAFELL spare parts and accessories may be used.
  Otherwise, the manufacturer will not accept any warranty claims and cannot be held liable.

Setting / Adjustment

Mains connection

Prior to initial operation, make sure that the mains voltage agrees with the operating voltage stated on the milling motor’s rating plate.

Selection of tools

Only use the collets/adapter sleeves listed in the chapter “Optional accessories”. Tools are selected depending on the materials to be processed and the capacity of the feed drives. Please take into account the milling motor capacity at maximum tool diameter and anticipated machining depth.

Tool change

Danger
Pull the power plug during all service work.

Wear protective gloves during a tool change. The insertion tool can get very hot during longer operation and/or the insertion tool’s cutting edges are sharp.

Tool clamping by means of collet

The spindle 1 (Fig. 1) of the milling and grinding motor is equipped with a precision collet 2 (Fig. 1) to hold the tools. The spindle lock is triggered by the locking button 4 and facilitates tightening and loosening of the union nut 3 (Fig. 1)

Proceed as follows for the tool change:

• Lock the spindle 1 (Fig. 1) to unclamp the tool by pressing the locking button 4 (Fig. 1).
• Detach the union nut 3 with an open-ended spanner AF 17 or wrench ER 16 M.
• Pull off the tool to the front.
• Push the new tool into the tool holding fixture up to the limit stop.
• Check the tool’s seat.
• Spindle 1 (Fig. 1) is locked when the tool is clamped.
• The union nut 3 is tightened with the open-ended spanner AF 17 / wrench ER 16 M.

Quick tool clamping

➢ Switch on the milling motor only when the lever 6 (Fig. 3) is not in the tool change position.
➢ Do not actuate lever 6 (Fig. 3) until the milling motor is at a standstill.

The spindle 7 (Fig. 3) of the quick tool clamping device is equipped with a precision holding fixture for a tool shank Ø 8.

Proceed as follows for the tool change:

• To unclamp the tool, move lever 6 (Fig. 3) forward up to the stop.
• Pull off the tool to the front
• Push the new tool into the tool holding fixture up to the limit stop.
• Check the tool’s seat.
• To clamp the tool, move the lever back to its original position.

Collets

Danger
To protect the thread, only screw the union nut 3 (Fig. 1) lightly onto the spindle 1 (Fig. 1), but do not tighten when no tool is inserted. Collet 2 (Fig 1.) could get pressed together too much and be damaged in the process.

Information on the use of collets:

• Please always use the correct milling cutter size for OZ collets (DIN 6388) and also for ER16 collets (DIN 6499).
• Please always click the collet into the union nut first, then insert the milling cutter.
• If jammed, please loosen the collet with a square timber or rubber hammer with a light blow from behind (no metal tool!).
• Please oil the collet collets at the beginning as well as after longer use as otherwise they can get stuck.
• A significantly better concentricity can also be achieved by using a solid lubricant (e.g. Molykote P-40) or by lightly greasing the collets.

Recommended tightening torques (observe overall system)

Tightening torque for union nut / collet = 10 -11 Nm
Tightening torque for clamping collar 43 mm = 7 Nm

The Euro neck mount “V” should not be smaller than dimension “h” (Fig. 8). Dimension “h” amounts to 20 mm. Clamp the milling motor as far as possible across the entire mounting diameter in the Euro neck mount “V1”
(Fig. 8). Tighten clamping screw „W“ with max. 7 Nm. (Fig. 9)

As far as possible, avoid punctual clamping (for instance using a grub screw) in the Euro neck mount „V2“ (Fig. 10).

Maximum speed when using a collet adapter
The recommended maximum speed for the use of the collet chuck adapter OZ and the collet chuck adapter ER is max. 16000 rpm.

Operation

Initial operation

Personnel entrusted to work with the milling motor must be made aware of the operating manual, calling particular attention to the chapter “Safety instructions”.

This operating manual only deals with the milling motor and does not consider the installation situation. Please take note of any other operating manuals.

Switching on

Push the power switch 5 (Fig. 1) forward until it engages. If the milling motor is connected to the mains voltage, the setting wheel X (Fig. 2) lights up in blue (BU) and the milling motor accelerates to the previously set speed after 0.2 s with a soft start. The duration of the soft start depends on the set speed and is approx. 1.2 s at maximum speed.

Switching off

Push onto the rear end of the power switch 5 (Fig. 1). The switch audibly jumps back to off position. The lighting on the setting wheel X (Fig. 2) goes out and the motor coasts to a standstill.

PV design

With the PV design Y (Fig. 2) you can control the speed via the PV interface and automatically monitor the remaining runtime in the event of overload.

To protect the user and the connected systems, the PV interface is electrically isolated from the power supply of the drive train (safety isolation). All signal and operating voltages refer to the reference potential “GND”. As soon as the supply pin “UPV” of the PV interface is supplied with voltage in accordance with the specification, the milling motor switches to “portal mode”.

The bottom status table 3 shows all possible control constellations.

Table 3: Possible control constellations

Legend:

When the PV interface is not in use, protect it against dirt with the supplied covering cap Z (Fig. 4).

Assignment portal connector

All pins on the portal connector are protected against reverse polarity. At voltages above 30 V, continuous operation with reversed polarity must be avoided as this can lead to failure of the PV interface.

Speed specification

With the setting wheel X (Fig. 2) you can adjust the speed continuously. The concrete speed values of individual stages can be found in the table on page 5 or on the speed sticker on the housing. Until the motor characteristic is reached, the built-in electronics readjust to the set speed.

Speed setting in PV design
In “portal mode”, the position of the setting wheel X (Fig. 2) for the speed setting is ignored. The speed can only be changed by the voltage at the pin “US“. If you wish to set the speed by means of the setting wheel X (Fig. 2), “portal mode” must first be deactivated by switching off the power supply at the pin “UPV“ or by removing the PV control cable.

The correlation between speed and control voltage is illustrated in formulae (1) and (2).

Overload protection

Danger
If you carry out any work on the working spindle after the overload protection has triggered, the mains plug must first be removed.
To protect the milling motor, the operating parameters current, speed and temperature are dynamically monitored and the power tool is switched off if necessary. Shortly before the overload protection is tripped, the illumination of the setting wheel X (Fig. 2) changes to a permanent red (RD).
To put the milling motor back into operation, you must open and close power switch 5 (Fig. 1). The milling motor goes into operation and the illumination of the setting wheel X (Fig. 2) changes to blue (BU).

Optical display of the remaining runtime

Triggering of the overload protection during operation leads to breakage of the milling tool, damage to the workpiece or even damage to the portal system. You can prevent this by paying attention to the visual output signals at the setting wheel X (Fig. 2).
As long as the milling motor is not overloaded in terms of performance, the setting wheel lights up permanently in blue (BU)

If the milling motor is overloaded, the calculated remaining runtime is displayed flashing in red (RD). On page 6 (Fig. 7) you can see the temporal arrangement of the pulses in overload mode. The correlation between the flashing behavior and the associated
remaining runtime is shown in the bottom table 4 on page 31. If the remaining runtime is not sufficient for your application, reduce the load or feed rate to be able to switch back to continuous operation.

Display of the remaining runtime in the PV design

If the milling motor is in “portal mode”, the remaining runtime can be queried via the PV interface in addition to the visual display.
The bottom table shows the correlation between the remaining runtime and the associated output variables.

Operating mode| Remaining runtime / s| Display remaining runtime U O / V| Setting wheel -illumination
---|---|---|---
Continuous operation| unlimited| 0| Blue (BU), permanent
Overload mode (motor is running)| < 160| 1.5| 1 x red pulse (RD)
< 80| 2.5
< 40| 3| 2 x red pulse (RD)
< 20| 4
< 10| 4.5| 3 x red pulse (RD)
< 5| 5| Red (RD), permanent
Switch-off| 0| 5

Table 4: Correlation between the remaining runtime and the associated output variables

Service and maintenance

Danger
