General
This Drilling and Tapping Unit is designed for normal drilling, countersinking, reaming and tapping. In
applications requiring high-precision hole placement or when drilling into rounded or slanted surfaces, drill
bushings must be used.
To be able to use the unit, it must first be installed and fitted with control equipment. Regardless of how
simple the installation is performed, the unit must be fitted with necessary protective devices to avoid
personal injury. Special precaution must be taken to eliminate the risk of clothing, gloves, hair, etc. being
caught in the rotating tool.
The unit consists of many components and preassembled parts, the reliability of which is dependent upon
proper maintenance. The pneumatic and hydraulic systems include a number of seals. It is essential to keep
moving seal surfaces clean and free of marks and scratches.
Installation
This Drilling and Tapping Unit is only intended for use in machinery which applies to the Machine Directive
98/37/EG.
WARNING!
Never use the unit without being securely fastened and that appropriate security
arrangements have been organised.
Be careful with rotating and moving parts, to avoid personal injuries.
Ensure that the unit is disconnected from the main air-supply, before any maintenance.
1. We recommend that this unit is installed in a place with clean air and an ambient temperature of
+10 - +40º C (+50 - +104 F.).
2. The unit must always be mounted on a level surface (machined) and attached with six M8 screws. On
the bottom side of the unit = mounting surface, there is a 10 mm wide groove for align the unit.
See Fig. 1.
Fig. 1.
3. The protective guards covering the limit switches or linear transducer are not sealed. Make therefore
certain not spray coolant or simliar over them.

4. Connection of the electric motor is done as shown in Fig. 2. and depending on which 3-phase voltage is
available. Check all the data on the electric motors data label to ensure that motor protection and
connection are properly carried out. Other types of motors can occure. The electric motor must be
equipped with a suitable control circuit and motor protection. The connection cable must have an area of
at least 1.5 mm
2
. Ensure that the motor rotation direction is correct.
Fig. 2.
If the phases L1, L2 and L3 are connected to the terminals as shown in Fig. 2 the motor shaft rotates
clockwise, seen against the shaft end on the drive side. Let two of the phase cables change place if the
direction of rotation needs to be changed.
Example of control curcuit: One way rotation for drilling and two way rotation for tapping.
Fig. 2a
5. Connection of the feeding cylinder. The connected compressed air must be of good quality.
6 – 7 Bars (87 – 101.5 Psi). Max pressure 8 Bars (116 Psi). The connection is made using an appropriate
air preparation unit with air filter and pressure regulator. Oil-mist lubrication is an advantage, but not
necessary. The unit is provided with plug-in couplings for plastic hose of Ø8 mm (5/16'') outside
diameter for compressed air connection. The inside diameter shall be ø6 mm (1/4''). See Fig. 3.

6. Drilling, countersinking or reaming: The units rapid advance and retraction movements should not
exceed a speed of 100 mm/sec. (0,33 fps) to ensure smooth operation and proper signal processing.
This is particularly important when the unit is equipped with a linear transducer. Regulation of the speed
is possible by fitting the hoses to the units feed cylinder, Port 1 and 2, with throttle-check valves. Place
the throttle-check valves as close as possible to the unit. See Fig. 4a.
Tapping: The rapid advance retraction should not be too high. Regulation of the speed is possible by
fitting the hose to the units feed cylinder advance, Port 1, with a throttle-check valve. Place the throttle-
check valve as close as possible to the unit. See Fig. 4b.
Fig. 4a. Fig. 4b.
7. Units delivered with pneumatic limit switches (choosen when ordering) allow automatic drilling
operation, pneumatically controlled in accordance with Fig. 5 where the valve (marked Start) is actuated
manually. Should repeated automatic drilling be desired, this valve must be replaced by a pneumatically
controlled valve which receives its activation signal from the control system of the processing machine in
which the unit is installed. Valves are V4 and V5 are pneumatic limit switches, which are delivered
mounted on the unit. Valve V1 shall be of 4-way, 2 position type and the the dimension of valve V1 shall
be 1/8" when the valve is used for a single unit.
Fig. 5.
8. If the unit is delivered with electrical switches, proximity switches or a linear transducer (choosen when
ordering), valve V1 shall be electrically controlled type of 4-way, 2-position type. The dimension of the
valve shall be 1/8" when the valve is used for a single unit. See Fig. 6.
Fig. 6.

- Between beige and yellow = no contact
Microswitch M2 is mechanically activated when the feed spindle is in "home position" = fully retracted:
Cable clolur coding: - Between black and blue = no contact
- Between black and brown = contact
- The green/yellow cable is used for earthing.
11. Connection of proximity switches for sensing the position of the feed spindle. The unit is delivered with
both switches and with cable lengths of 2 meter (6.56 Ft). Connection, see Fig. 6 and 9.
Fig. 9.

12. Connection of the linear transducer for sensing the position of the feed spindle.
The linear transducer is a potentiometer, which is delivered with a 2 meter (6.56 Ft) long cable
connected to the potentiometer with a PG9 connector, DIN 43650. To facilitate connecting the cable, the
leads are marked with their respective numbers as illustrated in Fig. 10. below.
Max. voltage for the liear transducer is 40V DC. Connection, see Fig. 6 and 10.
Fig. 10.
Important
Connect the transducer as a voltage divider. The amperage across the potentiometer must not exceed
1 µA. This is no problem if the inner resistance of the analogue IN-port of the measuring device is more
then 0,34 MΩ. Should the external control system require greater amperage, an amplifier must be used
in accordance with Fig. 11 below.
Fig. 11.
When the unit is delivered with a linear transducer, the hydrocheck is fitted with a 2-way valve (24V DC)
for the transition from rapid advance to working feed. This valve is normally closed, and for rapid
advance it shall be supplied with current at the same time as maneuvering valve V1 in Fig. 6. When the
output signal from the position sensor matches the set value for the transition to working feed, the
current to the 2-way valve is broken. If the unit is fitted with a linear transducer, the external control
system must have an analogue input connection to receive the analogue signal from the position sensor.
With the external control system (PLC), the transition from rapid advance to working feed or drilling
depth can then be choosen freely by setting the desired value using the control equipment, for example
for chip removal or multi-wall drilling.

10
Settings
1. Transition from rapid advance to working feed.
Setting the transition on units equipped with pneumatic, electrical or proximity limit switches is
performed with a screw, see Fig. 12, Pos. 1, which on return of the feed spindle, retracts the hydrocheck
piston rod into position for the next braking. To make it possible to set the transition along the entire
stroke length, the unit is delivered with two separate screws of different lengths.
When setting or changing the screw, the feed spindle must be advanced. If this is done using the units
compressed air system, the system must be depressurized before setting or changing the screw.
For units fitted with a linear transducer, the hydrocheck piston rod is fixed by screw to the adapter and
this follows the movement of the feed spindle completely. Setting is performed using the external
control system.
Fig. 12.
2. Drilling depth and forward-reverse position.
For units with pneumatic, electrical or proximity limit switches, the reverse position is set by first making
a coarse setting by placing the position sensor, see Fig. 13, Pos. 1, in the right position (4 positions).
Then place the cam, see Fig. 13. Pos. 2, in the right groove on the rod. The cam is locked into the
groove with a screw. In certain positions the threaded portion of the cam must be screwed out to expose
the screw. Setting is then accomplished with the threaded cam. One rotation corresponds to 1 mm
(.039 In). See Fig. 13.
For units with a linear transducer, drilling depth and the forward-reverse position are set using the
external control system and the analog signal from the position sensor.
Fig. 13.

11
3. Positive stop.
When more exact drilling depth or reverse position is desired, the positive stop is used. The units control
system must then be fitted with a time valve so that the feed spindle continues forward a short time
(0,5-2 Sec.) after the pneumatic or electric impulse from the position sensor.
First a somewhat shallower (e.g. 0,5 mm (.019 In)) drilling depth or reverse position is set than that
desired in point 2. The drilling depth or reverse position is then set using the adjustment screw, see Fig.
12. Pos. 2, and locked into position with a lock nut. Please note that the impulse from the position
sensor must be received before the feed spindle reaches the positive stop.
4. Working feed rate.
Setting the limit for the working feed rate is performed using the valve on the hydrocheck. The
adjustment is from 100% (full open) down to 0%. See Fig. 14, Pos. 1.
ONLY, adjust the working feed rate when the spindle is in “home position”.
Fig. 14.
Start-up
1. Ensure that the responsible operator has read and understood the manual before start-up of the unit.
2. Ensure that the safety measures in chapter "Security" are met before the start-up of the unit.
3. Follow possible local safety regulations.
4. Ensure that the installation is performed as described in chapter "Installation".
5. Check that the spindle rotates in the right direction.
6. Before starting check the setting of the transition to the working feed so that the tool does’nt enter the
workpiece at rapid speed.

12
Tool holders and Cutting tools
The unit can be equipped with the following tool holder types: (Choosen when ordering.)
Key Chuck: Drill Chuck: Tapping spindle: Collet Chuck: Collet with compensation
The following cutting tools can be used with drilling or tapping unit:
Drilling unit BE 48: Drills, Core Drills, Shank Mills, Countersinkers, Reamers or Brotsch.
Tapping unit BEG 48: Cutting Taps or forming Taps.
Drilling, Countersinking and Reaming
1. The transition from rapid advance to working feed must be set, see chapter “Settings” paragraph 1, so
that a margin of safety is provided allowing the speed to change to working feed before the tool reaches
the workpiece. Measure the distance from the leading edge of the tool to the workpiece and set the
distance in accordance with, Fig. 12, Pos.3 for a somewhat shorter distance.
Note! When the unit is equipped with a linear transducer, consideration must be taken to the reaction
time of the valve so that the value set using the external control system is sufficiently shorter than the
measured distance to allow braking.
2. Drilling depth and forward-reverse position should be set in accordance with chapter “Settings” par. 2.
3. Should the air pressure used on the feed cylinder result in a working feed rate that is too high, limit the
rate in accordance with chapter “Settings” paragraph 6.
Tapping
Tapping may be performed using a reversing die head or by reversing the tapping units electric motor.
Please note, that when reversing the electric motor, a tapping spindle with an axially floating tap holder
must be used.
1. When tapping, set the working feed rate at a somewhat lower value than that of the speed of the tap.
Tap speed can be calculated in accordance with the following: Rpm: 60 x pitch in mm = mm/sec.
Measure a distance and divide it by the measured time to determine the speed.
2. Tapping depth is then set using the forward-reverse position. See chapter “Settings” paragraph 2.
Note! When setting, the working feed rate must not be altered, as this will affect the tapping depth.
When tapping with a tapping spindle, the signal for reversing the electric motor must be given when the
feed spindle reaches the forward-reverse position.
3. The retraction rate of the feed spindle must be adapted to the speed of the tap at withdrawal to prevent
the axial movement of the die head or the tapping spindle from hitting bottom during retraction. The
speed is regulated using a throttle-check valve in accordance with chapter ”Settings” paragraph 6.
4. When tapping short lengths where the axial movement of the die head or tapping spindle take up the
entire tapping length, the feed spindle can be run to the positive stop after the tap strikes the piece and
then commence retraction after a predetermined time.
5. When using low retraction rates it may be necessary to delay initiation of the electric motors rotation for
withdrawal of the tap. This is due to the fact that air pressure in the plus chamber of the feed cylinder
must have time to drop for the feed spindle to retract.

Maintenance instructions
Daily inspection:
1. Ensure that the unit is free of chips and dirt that can cause disruption.
2. Ensure that the unit is running smoothly and that it is not making any unusual sounds. In the event of
any abnormal noise, immediately stop the machine and cal for service staff to rectify the fault.
3. Check that there is no external leakage on the hydrocheck. In the event of leakage, immediately call for
service staff to rectify the fault and then refill oil. See chapter ”Oil refilling of the Hydrocheck”.
Monthly inspection:
1. Check the oil level in the hydrocheck using the green oil-level indicator, see Fig. 15. Pos 1.
At max. oil level, the indicator is completely visible, and when only 2 - 3 mm (.078 – .118 In) are
showing it is advisable to add oil. If the green indicator is inadvertently depressed, it can be reset by
manually pulling it out again. To grip the indicator pin, loosen the hexagonal protective sleeve. For
refilling of oil see chapter ”Oil refilling of the Hydrocheck”.
2. Check the belt drive for wear and proper tension, see chapter ”Drive belt tension and Transmission
change out“.
3. Check the locking of the settings:
- Adjustment screw for transition to working feed. (Applicable for pneumatic, electric and proximity
limit switches.)
- If linear transducer, sleds attachment to the adapter.
- Drilling depth and forward-reverse position.
- Positive stop.
- Working feed rate.
Annual inspection:
In addition to the daily and monthly inspections, the following points should be observed.
1. Check the units pneumatic feed system for:
- External leakage.
- Leakage at the piston seal by performing the following. Advance the feed spindle to the positive stop
with out activating the signal for the forward-reverse position and check that there is no leakage of air
on the minus side. Note! Disconnect the hose to port 2, see Fig. 3 on page 6. Check correspondingly
for leakage at the piston seal when the feed spindle is in ”home postion”.
- Check that the feed spindle advances and retracts at an air pressure of 2 Bars (29 Psi). Without feed
control the feed spindle should advance and retract at 1 Bar (14.5 Psi).
In the event of leakage or if the feed spindle is sluggish, the feed system should be dismantled and
cleaned and all seals should be replaced. Note! When reassembling, lubricate bushings, seals, and the
cylinder barrel with a suitable grease.
2. Check the hydrocheck for:
- Scratches or marks on the hydrocheck piston rod.
- Leakage at the piston by lowering the working feed rate to 0 and checking that the feed spindle
practically stands still.
- Advance and retraction of the hydrocheck at 2 Bars (29 Psi) pressure. See paragraph 1 above.
In the event of leakage or problems with any of the above mentioned points, the hydrocheck should be
dismantled and cleaned and all seals and damaged parts should be replaced. For refilling of oil see
chapter ”Oil refilling of the Hydrocheck”.
3. Check the lubrication of the drive shafts splines by separating the belt housing from the mid-section.
Note that in certain cases the pulley on the drive shaft must be removed, see chapter ”Drive belt tension
and Transmission change out“. If necessary, lubricate the splines with a suitable grease.

14
Oil refilling of the Hydrocheck
Suitable oil quality: Hydraulic oil with a viscosity of e.g 32 cSt at +40º C (+104 F) and a high viscosity
index e.g. 345. Recommended oil: Castrol, Hyspin AWH-M 32 acc. to ISO VG32.
Oil quantity (filled): Ca 6,3 cl (2.22 fl.oz. (UK), 2.13 fl.oz. (US))
Oil refilling equipment: Part. no. 043J400426
WARNING!
1. When filling oil the feed spindle should be fully extended so that the hydrocheck piston rod
is fully retracted.
2. If, for some reason, the green level indicator, see Fig. 15. Pos. 1, is fully visible when filling oil, it should
be depressed manually.
3. Connect an oil injector to the oil filling nipple, see Fig. 15. Pos. 2, and fill oil until the green indicator pin
is nearly completely extended again. Note! Discontinue filling just before the pin is completely extended
to avoid excessive pressure in the system.
4. Whenever the hydrocheck has been disassembled or if air has entered the oil system, The system must
be bled when filling oil. The hydrocheck must then be turned so that its piston rod is facing upwards as
oil is being filled and the system is bled using the screw shown in, see Fig. 15. Pos. 3. Note! The piston
rod must be completely depressed while filling oil. Begin filling with the bleeding screw open and when
the oil stream is air-free, tighten the screw. Then fill with oil until the indicator pin Pos. 1 is extended.
Fig. 15.

15
Belt tension and Transmission change out
1. Belt tension must not be too great. Slide the tensioning pulley carefully against the belt and lock with
the screw in its center. Proper belt tension has been attained when the belt can be depressed approx.
20 mm (13/16'') with light pressure. See Fig. 16.
2. When changing the transmission, first loosen the centre screw for the respective drive pulley. The pulley
can be kept from rotating by mounting two screws (M6) in the threaded holes in the pulley and using a
metal bar. Then loosen the tensioning pulley and remove the belt. Use a puller to remove the drive
pulley if it cannot be loosened by hand. When removing the larger pulleys it may be too tight to use a
puller. In such cases the threaded holes can be used to mount a strip of steel plate with a screw in the
middle to press loose the pulley.
