General
The Secoroc BQ3-DTH grinding machine is designed to grind
cemented-carbide buttons and the surrounding body steel in the
same operation using a diamond-coated grinding wheel.The
machine has an automatic feeding device, which makes it simple
to use.
For grinding to be carried out, the machine must be fitted with a
grinding wheel, a centring cup, a bit holder and an indexing ring
to suit the bit that is to be ground.
Applications
The Secoroc BQ3-DTH is intended for grinding DTH, COPROD and
threaded button bits up to 178 mm in diameter.
Technical description
The Secoroc BQ3-DTH consists principally of the following com-
ponent assemblies:
• A driving plate that is rotated by an electric motor via a worm
gear.
• A grinding disc that is placed on the driving plate. When the cen-
tring button on the feed lever is pressed, an air cushion is created
under the grinding disc to facilitate centring of the button that is
to be ground. When the centring button is released, the grinding
disc is locked in position by a vacuum.
• A main holder, with a bit holder in accordance with the used
shank size.
• A centring device that adopts the centre position automatically
when the centring button is pressed.The centring device is in its
lower position when centering the button.
• A spindle that is rotated by an electric motor via a drive belt.
• An automatic feeding system for advancing the grinding wheel
on to the button. Feeding is effected by a pneumatic cylinder, but
manual feed is also possible.
• A coolant tank with pump to circulate the flushing fluid used to
cool the cemented-carbide buttons and the grinding wheel. Flush-
ing starts automatically when table rotation starts.
The button to be ground must first be centred directly under the
grinding wheel.Table rotation is then started and the profiled
grinding wheel fed down to the rotating drill bit.The centred
cemented-carbide button rotates inside the profiled groove in the
grinding wheel and is quickly restored to its shape.

General care
instructions
To ensure that your Grind Matic BQ3-DTH grinding machine func-
tions satisfactorily for a long time:
• Use original spare parts only.
• Read the maintenance instructions carefully before using the
machine.
• Make sure that the compressed air is always clean and dry.
• Check the water cooling function regularly.
•The incoming air and electricity supplies must always be discon-
nected during installation, servicing and moving of the machine.
• If the machine is not going to be used for a long time, make sure
that it is lubricated and cleaned before being left idle.
Installation
• Always follow the safety instructions with regard to installa-
tion, operation and maintenance.
WARNING
There is a lifting eye on the upper part of the frame. Always make
use of the lifting eye when hoisting the machine into place.The
weight of the machine is normally 345 kg. Make sure valid lifting
equipment is used.
To be able to work, the machine needs electricity, compressed
air and water. Before start-up fill up the pump and filter cup with
water.
The feet underneath the machine must be adjusted so that runoff
water flows towards the drainage hole.
Electricity
• Electrical connection of the machine is restricted to quali-
fied electricians only.
• Check that the electrical data for the machine is compatible
with the mains voltage.
WARNING
On delivery, the machine is connected for the specified voltage
and frequency. A power cable is supplied with the machine.
A main circuit-breaker must be fitted between the power cable
and the electricity mains when the machine is installed. Always
observe local regulations in respect of electrical connection.
IMPORTANT
After connection: Check that the motors rotate in the right direc-
tion.The grinding wheel should rotate in the direction of the
arrow. If the grinding wheel rotates in the wrong direction, switch
the phases.
The machine is protected against overload. In the event of over-
load, the motor overload protector will trip. Re-setting occurs
automatically after a period of standstill.
The machine is also equipped with an undervoltage circuit break-
er and an emergency STOP device. In the event of undervoltage
or activation of the emergency STOP device, the system must be
re-set prior to re-starting.
Compressed air
The exhaust air from pneumatic components contains oil mist,
which can be bad for your health if inhaled. Always adjust the
lubricator so that the correct amount of lubrication is obtained.
• Before filling up with lubricating oil, ALWAYS switch off the
compressed air supply and vent the machine.
•The maximum permissible working air pressure for grinding
machines with pneumatic components is 7 bar.
CAUTION
The compressed air must be clean and free of water.The machine
is equipped with an air filter.
On the Grind Matic BQ3-DTH, compressed air performs the fol-
lowing functions:
• It creates the vacuum that locks the grinding plate to the driver
plate
• It creates an air cushion under the grinding plate to make it eas-
ily moveable during centring
• It provides a suitable grinding pressure.
• Operate the centring arm.
Cooling
The drill bit and grinding wheel are cooled with water mist. At
the bottom of the machine is a sedimentation tank for grinding
residue. If the machine is used every day, the sedimentation tank
must be cleaned at least once a week.
Cooling water is switched on automatically when the grinding
spindle starts to rotate.Then, when the grinding plate starts to
rotate, the coolant valve opens and cooling water starts to flow.
With the coolant nozzle, water is sprayed over the whole of the
grinding wheel.
Cooling is very important to the service life of the grinding wheel
and to the grinding result. If cooling is poor, thermal stresses can
be ground into the cemented carbide button, with subsequent
button breakage as a result.The service life of the grinding wheel
falls dramatically if cooling is poor.
A coolant mixture consisting of cooling concentrate and water
(mix ratio 1:30) should be used. Use the recommended cooling
concentrate.The concentrate contains a rust inhibitor.
Grinding plate
Before the grinding plate is put on, the contact surface must be
clean and preferably oiled as well. Check that the O-ring on the
driver plate is fitted.
Place the grinding plate carefully on to the driver plate.Turn on
the compressed air and check that the grinding plate “floats“
smoothly when the centring button on the feed lever is pressed.
In the beginning, the plate can bind a little. If so, move it around
for a few moments to alleviate the problem.
The air cushion can be regulated by means of a valve, located
next to the return pressure regulator. If there are great pressure
variations in the compressed-air supply, it may be necessary to
stabilize the pressure by means of an external pressure regulator.

7
Grinding wheel
• Before fitting or removing a grinding wheel, switch off the
electricity supply.
•The grinding wheel is hot immediately after grinding.Take care
not to burn your fingers when changing the grinding wheel.
Fit the grinding wheel to the grinding spindle.
The smaller side on the grinding wheel must face away from
the grinding machine. Make sure that the journal of the spindle
is clean and lightly oiled.This will make it easier to remove the
grinding wheel.
If the grinding wheel cannot be removed using hand force only,
make use of the puller supplied with the machine.
Do NOT use impact or excessive force on the spindle or
grinding wheel!
IMPORTANT
Grinding
• Always check that there are no traces of explosive in the
flushing holes of the drill bit.To clean out the flushing holes,
ONLY a wooden stick, a length of copper wire or flushing
water may be used.
• Beware of the risks of fire or explosion that might be initi-
ated by sparks from the grinding work.
DANGER
• Never remove the grinding guard from the machine.
• Make sure that the grinding station or place of work is well
ventilated.
• Always wear goggles, protective clothing, gloves, dust mask
and hearing protection during grinding.
• Before removing or fitting a grinding wheel and before chang-
ing the drill bit, always switch OFF the electricity supply.
•The grinding wheel is hot immediately after grinding.Take care
not to burn your fingers when changing the grinding wheel.
•To prevent injuries caused by crushing, avoid moving parts
when the machine is running.
CAUTION
General rules
Adequate cooling is crucial to the service life of the grinding
wheel, and also to the grinding result. Poor cooling can result in
heat stresses being “ground into“ the cemented-carbide buttons,
with button fracture as a result.The service life of the grinding
wheel falls dramatically if cooling is poor.
Pressing the grinding wheel too hard on to the cemented-carbide
button will reduce the service life of the wheel. Both the grind-
ing wheel and the cemented-carbide button can be damaged by
excessive heat generation. A new grinding wheel must always be
“run in“. Start grinding carefully and increase the feed pressure
gradually.This practice will increase the service life of the grinding
wheel substantially.
The manufacturer disclaims all responsibility for any prob-
lems (or consequences thereof) attributable to the use of
non-original grinding wheels.
IMPORTANT
Steel removal
In the case of heavy bit wear, one should remove the steel around
the button to obtain maximum service life of the diamond grind-
ing wheel.This is done in the simplest way by means of using the
grinding wheel for removing body steel, alternatively by using a
straight silicon-carbide grinding wheel or by sand-blasting.

Set up and preparations
• Fit the bit holder* that correspond with bit shank.
• Fit the grinding wheel* that corresponded with button size and
profile.
• Fit the centering cup* that corresponded with button size.
* Parts found in section Accessories.
Grinding instructions
With the Secoroc BQ3-DTH grinding machine, there are two differ-
ent operating modes to choose between:
A� Automatic feeding with pre-set bit-grinding time
B� Automatic feeding only
Automatic feeding with pre-set bit-grinding
time
When grinding in the most automated mode (A), the switch
should be turned so that the green lamp at the rectangular
symbol with arrows lights.
IMPORTANT
Before grinding, make the following adjustments:
1. Adjust the grinding pressure by means of the regulator and
table.
2. Adjust feed speed on the regulator, so that the grinding spindle
does not go down so fast that the grinding wheel strikes the but-
ton in the bit.
3.Tilt the main holder to make it easier to fit the drill bit into the
bit holder. Now tilt back the main holder and make sure that it is
locked on to the grinding disc.
4. Note that the gauge buttons should be ground first. Adjust
therefore the angle of the main holder to match the angle of the
gauge buttons in the drill bit, so that the centre-line of a gauge
button is always vertical during grinding. Button angles for your
bit can be found in Secoroc product catalogues.
5. Press and hold the centring button on the feed lever. The
centring arm moves to the centring position and an air cushion is
formed under the grinding disc, causing it to float.
6. Align the grinding disc and press down the feed lever so that
the button to be ground locates exactly in the middle of the cen-
tring cup. (Make sure that the size of the centring cup agrees with
the size of the button).
7. Release the centring button, whereupon the grinding disc is
locked into position on the driver plate by a vacuum, and the
centring arm retreats. Note that there is a built-in delay in the
system to ensure that the centring arm stays in the centring posi-
tion while the vacuum is being formed, in order to prevent the
bit from moving.The delay time can be adjusted by means of the
time relay.
8. Set the desired grinding time by turning the graduated wheel
on the potentiometer. Make sure that the light for AUTO is on.
9. Start the grinding spindle by pressing the left green button on
the control panel.
10. By means of the feed lever, lower the grinding wheel carefully
toward the button.
11. When the grinding wheel is about 15 mm above the button,
switch on the automatic feed. Bit rotation starts, coolant begins to
flow through the nozzle and the feed cylinder is activated.
12. Put the stroke limiter switch into ON position to lock the stroke
position. Leave the switch in this position until the last
gauge button has been ground.
13. When the pre-set grinding time expires, the feed cylinder
releases, the flow of coolant stops and table rotation stops.The
grinding spindle rises to about 10 mm above the button. If the
button has not been ground enough, set the potentiometer to a
longer interval. If the button has been ground too much, a shorter
grinding interval should be set. As a rule, buttons are ground
more quickly when the grinding wheel is new.
14. Check the grinding result and adjust the potentiometer as nec-
essary. Make sure that full dome height is obtained, but always
leave a 1-2 mm wear flat on top of the button to avoid grinding
away too much of the cemented carbide.
15. Index the next button by turning the drill bit.
16. Switch on the automatic feed.
17. Repeat steps 15-16 until all gauge buttons have been ground.
Automatic feeding only
When grinding in semi-automatic mode (B), button should be
set so that the green lamp by the hand symbol lights.
IMPORTANT
1. See points 1–4 under “Automatic feeding with pre-set grinding
time”
2. Start the grinding spindle and table rotation by pressing the
respective green buttons on the control panel.
3. By means of the feed lever, lower the grinding wheel carefully
toward the button.
4. When the grinding wheel touches the button, activate and hold
the switch until the desired grinding result has been obtained.
5. Check the grinding result. Make sure that full dome height is
obtained, but always leave a 1-2 mm wear flat on top of the but-
ton to avoid grinding away too much of the cemented carbide.
6. Stop the table rotation.
7. Index the next button by turning the drill bit.
8. Repeat steps 3–7 until all gauge buttons have been ground.
Setting the grinding pressure
To get the most out of your grinding machine, make sure that the
operating pressure is set to a level that provides an optimal grind-
ing force of 150 N.This can be done by easy means.
• Measure the distance between the grinding disc and the top but-
ton that is about to be ground.
• Search for the closest distance in the table.
• Adjust the pressure settings accordingly.

For best grinding results and wheel life:
• Centralize the buttons precisely.
• Make sure there is a generous flow of coolant at the point of contact.
• Grind carefully and do not rush.
• Let the machine do the work.
• Do not try to speed up grinding by adding hand pressure to the
feed lever.
• Use original grinding wheels only.
• Use recommended pressures.
Grinding hints
The rate of bit wear depends on the rock formation, and is highest
in rocks with a high quartz content. A suitable grinding interval
should be determined according to the rate of bit wear. It is more
economical to regrind too early rather than to suffer poor penetra-
tion rates and risk damaging the drill bit through overdrilling. A
few hints about the care of drill bits:
When to regrind
Button bits should be reground
when the penetration rate drops,
or if any of the cemented-carbide
buttons are damaged (fractured
buttons should be ground flat). It
is both practical and economical to
redress the buttons when the wear
flat reaches about 1/2 of the diameter of the button.
Look out for “snake skin“
If microscopic fatigue cracks – so-
called “snake skin“ – begin to
appear on the cemented carbide
buttons, the cracks must be ground
away. In any event, bits should be
reground after 300 metres of
drilling at the most. This should be
done even if there are no visible signs of wear and the penetra-
tion rate continues to be good. If snake-skin is not removed, the
cracks will deepen and ultimately result in button fracture.
Always grind broken buttons flat
A drill bit can remain in service as long
as the gauge buttons maintain the
diameter of the bit. Fractured buttons
must always be ground flat to prevent
chips of cemented carbide from
damaging the other buttons.
Avoid grinding the perimeter
2 mm
Min
0,5
Gauge button anti-taper has to be removed by grinding, although
excessive reduction of the bit diameter should be avoided. Leave
about 2 mm of the wear flat.
If necessary, remove some of the bit-body steel below the gauge
buttons, so that a clearance (taper) of 0,5 mm is maintained.
Make sure that the flushing holes are open.
Maintenance
• Before attempting service or repair work on the machine,
ALWAYS switch off and disconnect the electricity supply and
the compressed air supply.
CAUTION
Cleaning
Keep the machine clean at all times.This is the cheapest and easi-
est way to maintain the machine.
Lubrication
Most bearings and bushings in the machine are permanently
lubricated and do not normally need any maintenance. Use the
grease nipples to lubricate moving parts.
Follow our recommendations found in this instructions, section
"Recommended lubrication and cooling liquids".
Disposal
A used machine must be treated and disposed in such a way that
the greatest possible portion of the material can be recycled and
any negative influence on the environment is kept as low as pos-
sible, and with respect to local restrictions.
Cooling liquid
Particles of cemented carbide and steel gradually accumulate in
the sedimentation tank. Empty and clean out the tank regularly. If
the machine is used every day, the sedimentation tank should be
cleaned out at least once a week. Since the water in the tank con-
tains particles of cemented carbide, local regulations (in respect of
water contamination) must be observed when it is emptied.
Fill the sediment tank with new fluid consisting of a mixture of
cooling concentrate and water (mixing ratio 4-8%). Apart from
cooling the grinding wheel and cemented-carbide buttons, the
cooling fluid serves to prevent rust in the machine.
If the machine is not going to be used for some time, the cooling
system should be drained. If the machine is not going to be used
for a long time, it should be oiled generously.
Water filter
Use the wrench to open and/or close the cup.
Air filter
The air filter prevents particles of dirt and also water from enter-
ing the pneumatic system. It should be drained and cleaned
regularly.The water level in the bowl must not be allowed to rise
as high as the separator disc.

10
Draining the air filter
Drain the air filter regularly by pressing the drainage valve
upwards.The filter is also drained automatically when the
compressed air is switched off. A hose can be connected to the
drainage valve if required (to discharge the water in a convenient
place).
Cleaning the air filter
• Unscrew the filter bowl
• Unscrew the separator disc
• Clean the filter
• Blow clean the filter from the inside out
• Fit back the filter
• Fit back the filter bowl
Ejector
The pneumatic system includes an ejector that serves to create
the vacuum which locks the grinding disc and driver plate to each
other.The ejector does not normally need any maintenance. If it
needs to be cleaned, simply remove the connection nipples and
blow clean the ejector housing.
Grinding spindle
The spindle is manufactured with great precision. Rough handling
can reduce the service life of grinding wheels. Care must there-
fore be taken when changing the grinding wheel. If necessary, use
the puller to remove the grinding wheel, product code 87005058.
Before fitting a new grinding wheel, lightly grease the spindle.The
bearings of the grinding spindle are permanently lubricated and
does not normally need further lubrication.
Dismantle, overhaul and assemble.
The outer nut threads are different.The one at the front end
(87000780) has a right hand thread, turn counter-clockwise to
open.The one at the back (87000781) is a left hand thread.
The inner nuts are all right hand thread.
To remove the ball bearings, pull them off. Use a puller. Check
that the spindle shaft is in good condition. If the shaft has run out
larger than 0,02 mm, replace it.
Vibrations will effect the grinding result and the life of your
diamond grinding wheel.
IMPORTANT
When mounting the bearings back on to the spindle. Press them
back. Use a sleeve.
Fill each of the new ball bearings to 25% with the recom-
mended grease. – Do not overfill the bearings!
IMPORTANT
Note the direction of the disc springs.
Grinding disc and driver plate
Make sure that the surfaces between the grinding disc and the
driver plate are always clean.The O-ring between the two plates
must be checked regularly. Damage to the O-ring will reduce the
strength of the vacuum. Small amounts of oil can be used to
prevent corrosion.
Protective bellows
The bellows serve to protect the tubular ball guides from dirt.
Make sure that they remain in good condition in order to prevent
grinding dust from entering and damaging the tubular ball
guides.
Drive belt
The drive belt between the
motor and grinding
spindle can be tensioned
by adjusting a spring-
loaded screw on the
motor shelf.
It is important for the motor shelf to be correctly adjusted,
otherwise the drive belt can wander on the jockey wheels,
which can result in damage.
