3. Brief description of the driving system and its structure:

The machine consists of spindle box, column, machine base, worktable and its bracket,
electric cabinet, coolant device and machine accessories, total seven component parts.
Spindle revolution is main motion of the machine. During drilling and milling processing,
spindle movement along with its axis is a feed motion, during milling operation, movement
of worktable in longitudinal or cross directions or rotation of the worktable is also a feed
motion. Worktable up and down movement and worktable turn round itself is an auxiliary
motion. To those big or higher work piece that could be clamped on the worktable of the
base. The worktable and its bracket should turn round the column to a proper area far away
from the machining area.

Two separately vertical motors realize machine transmission. A special pump supplies
coolant water.

Two operating levers in the front of spindle box could make changes for the spindle speed
in 12 steps. Changing either lever position could drive a triple gear and a quadruple gear
moving along with axis direction results the speed change. One of levers has an idle
position that is for the spindle rotation by manual for loading and unloading of tool cutters
as well as for the adjustment of work piece only. Adjustment of the feed rate could be
realized by shifting a set of gears controlled by changing a lever position in the right corner
of spindle box. It also has an idle position for disengaging power feed transmission of the
spindle for the micro adjustment of the spindle by manual.

Up and down movement of the worktable and its bracket is completed by a vertical speed
reduction motor. Of cause, little adjustment for the height of the worktable could also be
made by manual.

Two kinds of lubrication, auto or manual, of the machine are available. Auto lubrication
system consists of a filter ( located inside of a tank under spindle box), a lubrication oil
pump and an oil distributor (located on the top of spindle box), a visual window and an oil
nozzle etc.
Please refer to the diagram 2 for the transmission system of the machine.
For the gear, worm and worm shaft, rack and pinion etc, please see table 1.
For the details of roller bears to be used on the machine, please refer to the diagram 3 and for
a list of roller bears, please refer to the table 2.

4. Electrical system
4.1 Brief description

The machine with foreign advanced singlechip and superior quality electric element is controlled by electric
system, the software system not only realize all kinds movement control ,but also has many protective
function with catenation, the capability of this system is very good ,and the movement of this system is
jarless and reliable.the move and stop of the main motor function are used by electric circuitry, and it
improved the arrury of machine’s drilling.

4.2 Explanation of the circuit

When using the machine,breaker QF1,QF2,QF3 which positioned electric box B1( drawing 4) must be
closed,it can be opened when examined and repaired. The two breakers separately protect short circuit、over
loading and short phase of spindle motor and pump motor .when close the chief switch QS1, the system is
entering working state and the single lamp HL1 ligh up ,when break the chief electric source, the lamp
crush out and working stopped.

4.3 Tapping operation:

Electric Element for the tapping control mainly contactors KM1 and KM2, selection switch SX1 and limit
switches SQ2 and SQ3 for tapping depth control.put the selection switch SX1 into the “1”(“0”is for hole
drilling only),arrange the spindle revolution in clockwise direction KM1 engaged), put the spindle manual
opration lever in down position until touches work piece, tapping job noe is starting. When requied depth is
reached , the limit switch SQ3 works, the spindle immediately runs in counter clockwise direction (KM2
engaged), the tap returns out of the work piece, when spindle returns to the up highest position ,the limit
switch SQ2 works, spindle runs in clockwise direction, now one tapping job is finished. If tapping stop is
required, push the button (SB4) on the lever end , the spindle motor will immediately run in count
clockwise direction, that’s all.
If the selection switch SX1 is in the “0”position, normal drilling work starts.

Attention: As the spindle motor works frequently during tapping,the motor will be hot quickly ,so the
tapping job could not be down for a long time, eight times of tapping per minutes maximum
is recommended as the motor needs cool when it is hot otherwise it will be burned.

4.4 Auto feed operation:

When auto feed , moving spindle down 5-6mm, press a push button at the end of either one of the three
levers, now feed clutch is engaged and indicator HL2 on the panel is lighted auto feed job is started.
When required drilling depth is reached ,the limited switch will be pressed, then spindle returns
automatically. Press the push button of the lever once angin, auto feed will be stopped and the spindle will
return back to the original place.

4.5 Emergency stop operation:

If emergency stop is necessary during operation, press emergency push button SB1 that makes
the loss of electric power of the contactor KM1,so the machine is completely stopped .After
eliminating the breakdown ,release the lock of the push button then restart the machine.

4.6 Coolant pump

Revolving the switch of coolant pump right, then the coolant pump is moving and working
with the spindle. When the spindle stopped, the coolant pump stopped too.

4.7 Lifting motor

The clamping handle 22 must be opened when the worktable lifting, turn the push button SX3
at required position.

4.8 Installation of the main motor:

Insert the key of the main motor into the solt position of the spline shaft then fixed by 4-M10
×35 hex screw bolts. Connect three phases and one ground wires to the power supply as per
the electrical Diagram(5) of the machine.(please note the direction of main revolving).

4.9 Sheet metal guard:

The sheet metal guard of this machine has a safety protection function, when it is opened
The spindle can’t working, until it is closed when the spindle is working now, it immediately
stopped if The sheet metal guard is opened .

4.10 Maintenance of the electric equipment:

Turn off the electric power befere maintenance of the electric equipment starts.The electric
equipment must keep on clean condition. Therefore, regularly cleaning is necessary.
However .liquid such as kerosene, gasoline and detergent etc.is not be allowed for the
cleaning. Wave of power supply shall not be over ±10% requied by the electric motor.
Maintenance of electric equipment is absolutely important inorder to keep machine works
well.

5.Lubrication and coolant system:

Lubrication system:

Parts and bearings inside of the spindle box are all automatically lubricated. Oil level shall
be a little bit higher than the centerline of the oil window when you fill lubrication oil. Too
much oil filling will cause overflowing. Oil release plug and a filter device are in the same
unit located at left side down of the spindle box. Please pay attention that when fastening
your oil release plug, don’t forget to put the oil absorption pipe inside of the filter,
otherwise no filtered oil will be available. The filter needs to be washed once every two
weeks.
For lubrication places and its requirements by manual. Please refer to the diagram 6.

Coolant system:

A special pump will supply coolant both for tool cutter and for work piece during machining.
Coolant liquid is stored in a compartment located at the backside of the machine base. Flow
rate of the coolant could be adjusted by a ball valve. Regularly washing for the coolant
system is necessary and coolant water shall be exchanged as per actual condition.

6. Hoisting and installation:

Hoisting:

The machine is strongly fixed inside of the crate. When hoisting the machine, please pay
close attention to the sign outside of the crate (where the wire cable shall be placed and
where the gravity center is).
The crate must not be reversed or inclined and must not be strongly stroked when lift up the
machine.
Considering small size of the bottom and higher size of the height of the machine package,
therefore, moving the machine by roller is forbidden. Lifting by a crane or by forklift is
recommended.

Please refer to the diagram 7 for the machine lifting. A soft pad between machine and wire
cable is necessary in order to avoid paint damage of the machine. Lifting must be slow at
beginning to see if the gravity center is correct.

Installation:

Working area of the machine shall be the size when the worktable rounds its column in one
cycle. Its diameter is about Ø2000mm. Further more, space for the work pieces, toolbox, and
machine accessories as well as operating and maintenance space must be considered.

The machine should be placed on a solid ground. No foundation construction is required if

ground of workshop is solid enough. However, we suggest that you’d better to make a
foundation as per the attached drawing 8 and shall consider some space for foundation screw
bolts use.

When the foundation is completely dry, the machine could be laid down on the adjustable
pad. Concrete could be filled when screw bolts are placed. Fastening screw bolts after
concrete is completely dry. Leveling the machine first, required tolerance should not be
over 0.04/1000mm both in horizontal and cross plane. Checking all items of the accuracy as
per the table sheet of the certificate. Accuracy value for each checked item must not be over
the required value.

Preparation before machine running:

A strict checking, testing and try cutting of the machine have been made before machine
delivery. No adjustment of the machine itself is necessary. Before machine running, clean all
surfaces of the machine first by using cloth with kerosene or gasoline, checking all
lubrication points then turn the main switch of the machine to the “on” position, running the
machine with middle or slow speed and checking all revolution direction is correct, operating
levers are in a correct position, checking machine noise and working temperature are all ok.
The machine should be running for a certain period of time, then it could be used if no any
un-normal condition happened.

7. Use and operation of the machine:

For the operating levers, handles, electric switches and buttons, please refer to the diagram 1
and diagram 4.

Mounting and dismounting of tool cutters:

The machine equipped with a tool dismounting device to be controlled by a nob ( 16 ). Push
forward the nob ( 16 ) to the spindle box direction when tool mounting is required. As for
dismounting tool cutters, pull out the nob ( 16 ), hold the tool cutter by left hand,
meanwhile, turn the feed lever ( 4 ) by right hand, then the spindle quill goes up rapidly,
the tool cutter will fall down until tool taper shank strokes the shaft of spindle.

In case too tight mesh between tool shank and spindle taper and the tool cutter could not fall
down after several strokes, then you have to use the normal way by using a taper wedge to
dismounting the tool cutter.

If milling cutter is used, be sure to take away the screw on the tool holder screwed on the end
of the spindle, the milling cutter then could be easily dismounted.
Warning: The nob (16)must not be pulled out while tool mounting or machine
Running, otherwise, the spindle will goes up quickly which results tool
cutter falls down. It is really dangerous.

7.3 Changes for the spindle speed and feed rate:

Spindle speed change could be made by moving the two levers ( 14 ) and ( 15 ) located in
the front of the spindle box. Relations between spindle speed revolution and levers position
is indicated at the speed change label. Meanwhile, the digital meter indicates the actual
spindle revolution.

As mounting or dismounting tool cutter or adjustment of work piece needs spindle rotation
by manual, therefore, the lever in the right side position shall be in the “idle” position, so
spindle rotation could be easily obtained.

Changes of the feed rate could be realized by using the lever ( 5 ) in the upper right side
position of the spindle box. As micro manual feed needs disengagement of the auto feed,
therefore, the lever shall also be in the “idle” position.

7.4 Selection and operation of the spindle feed:

There are three types of spindle feed selections for your choice as per the requirement of
your machining:

Manual feed: Simply moving the feed lever( 4 )at the right side of the spindle box, the
spindle will move down if turned the lever in counter clockwise and the
spindle will move up if turned the lever in clockwise.

Auto feed: There are three levers( 4 ),at the end of each lever equipped with a push
button.Push one of any three buttons( SB4 ), auto feed could be realized as
per your required pre-set feed rate. Push one of any three buttons( SB4 ) once
again, the auto feed will be stopped immediately.
Page 25 Instruction Manual for GHD-50 (D178) 23/12/2014

Total 26
Operation Manual
page 23
Manual micro feed: Spindle micro feed needs two steps. First, put the feed rate lever( 5 )in the
“idle” position. Secondly, push button ( SB4 ), then push up the micro
feed hand wheel( 3 ) and make sure that the clutch is engaged, now the
micro feed hand wheel could be turned and micro feed of the spindle
works.

7.5 Cutting depth control:

For the batch production, you need control cutting depth. A scale in front of spindle box could
meet your requirements. Loosening knurled screw ( 20 ) by turning nob ( 2 ), moving the scale
to the required depth, then fastening the knurled screw( 20 ). Now the machining depth could
be controlled.

7.6 Application of the digital scale:

A small round battery is fixed on the right side position of the spindle box for digital
readout. With this scale, moving distance of the spindle could be easily readout. Except the
battery switch, a “reset” push button and an “English or Metric” converter push button are
available. Cutting depth could be readout at any time and cutting depth could also be set in
advance. This function will be helpful for small batch or single work piece machining.

7.7 Tapping:

Put the “Selection Switch”(18 ) on the tapping position first, turn the feed lever( 4 ) and let
the tap approaches the work piece, a proper manpower force (based on the size of screw)
shall be exerted in order to let the tap comes into the hole. The spindle will be rotated in
reverse when the screw depth is reached, and the tap comes out.
Suppose, tapping job needs stop, push button ( SB4 ) of the hand lever( 4 ) then spindle will
have reverse revolution. and tap returns back.

7.8 Milling

Choosing milling cutters and accessories as per the machining requirements and shape of the
work piece. Milling cutters could be fixed on the spindle via tool holder or drill check. Put
accessories on the worktable and fasten it, turn the worktable and let its pin in the bottom
approaches right side position of round column and let lock block clamps the pin and fastens
it by screw, be sure to clamp it in force by clamping levers( 6 ) and ( 22 ) .
Page 26 Instruction Manual for GHD-50 (D178) 23/12/2014

Total 26
Operation Manual
page 24

For the milling operation, manual feed or auto feed using lever( 4 ) is not permitted. The best
way is to use micro feed hand wheel( 3 ). Lock spindle by turning a clamping rod( 6 ) if
required cutting depth is reached. Now milling operation could be started.
Warning: The clamping rod ( 6 ) is to be used only for clamping the spindle while
Milling. Therefore, for the job of drilling or tapping, the clamping rod
shall be released. Otherwise, the spindle quill could not be moved and
quill surface will be destroyed.

7.9 Adjustment of worktable position:

Symbols multi-use and convenience of the machine also reflects multi function of its
worktable. Except its normal manual and auto up and down function, it can also be turned
around the table itself, around the column and tilt in ±45°in horizontal position.

Operation method for the table tilting

Using a special tool to take out the taper pin and loosening four screw nuts on the bracket
and manually turn the worktable to the required position then fastening the four screw nuts,
now the work piece can be machined as per your tilting angle.
When the job is finished, keep the worktable in the original position by using the same way
mentioned on the above. Be sure do not forget to push the pin in its position.

8. Machine adjustment:

8.1 Spindle balance force adjustment:

Balance of spindle is realized through a springiness from a coil spring device located at the
left side of the spindle box. Balance force shall be adjusted to the point that the spindle
together with its tool shall not go down itself when spindle stops. (go up a little bit shall be
much better).
Over springiness or less needs adjustment. Simply loosening the screw on the cover of spring
box, turn the spring box cover, the spring could be either fastening or loosening. Fastening
screw on the cover if the balance force is ok
8.2 Adjustment for the feed safety clutch:

Feed safety clutch is mounted on upper side of the warm shaft. If too much feed resisting
force is occurred, the feed safety clutch will be automatically slipped (sound “Ka” will be
heard) in order to protect machine driving system not to be damaged. Clutch appearance could
be seen when opening the cover below the feed change label.
Using a tool to turn a slotted nut in clockwise, this will increase the feed resisting force,
meanwhile, the counter clockwise will reduce the feed resisting force. The max. feed
resisting force of this machine is 10000N, Over feed resisting force will cause un-safety, be
sure to lock it by screw bolt or nut after adjustment.

9 Machine use and maintenance:

9.1 Before running the machine, carefully read the Operation Manual first, fully understand the
structure of the machine and its performance and needs to familiar with locations for all
levers and buttons.

9.2 Lubrication of the machine is very important. Daily lubrication work as per the equirements
of the operation manual is necessary. Filter should be cleaned once every two weeks
therwise pump, transmission parts and bearings will be damaged.

9.3 Max. spindle torque of this machine is 160Nm. Max. feed resisting force in the driving
system is10000N. Over permitted cutting feed range is not allowed. High spindle speed with
big cutting feed is not good to the machine.

9.4 As standard drill with118 degree angle features big cutting force but quick wear-out, so
diameter and roughness of holes is not so ideal after drilling, therefore, regrinding its edges
particularly for the big diameter drills is necessary. It is better to use two different angles for
the machining of cast iron material (Second angle could be 70°).

9.5 Spot facer with three edges is proffered for the spot facing machining, using a normal drill
for spot facing job will cause vibration. However, it will have a better result for the spot
facing machining if reducing the rear angle of the normal drill with two different angles and
going down the cutting speed and feed rate.

9.6 Temperature of motor will be increased so quickly when tapping due to frequently Motor
direction be changed. Therefore, rapid and continuous taping shall be avoided. Max. eight
times per minutes of tapping is recommended. The machine shall be stopped for cooling if
the motor is too hot.

9.7 A proper cutting force is required when milling. As this is not a milling machine although
it has a milling function. Too big milling force will cause worktable moving round the
column, therefore, clamping the worktable strongly is required when milling and a
reasonable cutting feed rate for milling job is necessary.

9.8 Please turn off the coolant valve when mounting and dismounting tools, clamping or
adjusting work piece or measuring work piece, as coolant is not necessary during this period.
Stop coolant pump if these job takes more than ten minutes.

9.9 As gears are to be used for spindle and feed system, so it is not allowed to change spindle
speed or change cutting feed rate when machine running, otherwise it will damage gears,
shafts or relevant parts.

9.10 Do not extend spindle quill too much, instead, a proper working table height is
suggested .Clean the spindle taper hole and tool taper shank first before tool mounting.
Unqualified or rusted or damaged taper shank is forbidden to use.

9.11 Dry agent inside of the electric box and regularly removing dustiness are necessary. It is
forbidden to us gasoline or kerosene or diesel oil to clean electric components. We suggest
to use those no erosion and not be easily burned liquid such as carbon tetrachloride etc.
