4. Delivery and installation

The lathes are carefully packed in our factory.

Please check the following on delivery:

1. whether the packaging has been damaged and/or:

2. whether the lathes shows signs of transport damage or if there are grounds for

complaint. In this case we request your immediate notification. Claims made at a later
date cannot

be acknowledged.

The lathe must be installed on an appropriate, level and firm base.

This would be, for example:

 a base cabinet such as in our accessories programme
 own work bench as long as it is strong enough to carry the weight of the machine without

warping (see technical data and check with spirit level) and has an even surface.

 a steel plate

The lathe must be firmly screwed down onto the base. To facilitate this, there are 9 mm holes in the
machine base. Good results and a minimum of vibration during operation can only be guaranteed if
the above mentioned requirements for secure mounting have been kept to.

The installation of the machine should take place where there is sufficient lighting, electrical cables
with earthed sockets and O-conductors are installed adequately near to the machine so that the
mains connection lead is not subject to any tension whatsoever. The mains lead should be such
that, by means of a multiple socket, a coolant or lubrication unit can also be connected.

25

5.

Starting-up and maintenance

i

Fix the machine on a sturdy, level support
Use sharp processing tools
Adjust speed setting and feed to fit the material and diameter of the tool
Clamp the tools so that the clamping position is as near possible to the
workpiece
Clamp the workpieces fast and without vibrations.
Long pces. support with tailstock or with fixed stay.
Apply coolant and lubricant for better surface quality (finish) and
dimensional accuracy
Fix processing tools and workpieces on clean clamping surfaces
Grease the machine sufficiently
Use the correct tools for removing the material from the workpieces
Set correct bearing clearances and align guides early enough

6.

Overload protection

i

Wait approx. 1 second after switching off the machine manually or after an
automatic switchdown follow ing an overload before you sw itch on again.
This will ensure that the motor is protected effectively in all work situations.
Otherwise it is possible that the machine will not come on because the
relay for the electronics has not been able to function.

26

7. Safety Instructions

1. The feed line for the motor may only be connected to a shock-proof socket or junction box.

(Have the socket or junction box checked by an electrician beforehand; protection against
children being able to put into operation).

The socket or junction box must be close enough to the equipment, that the current-carrying

cable is subjected to no tensile strain whatsoever.

2. The three-phase A.C. motor must be connected by an electrician over a protective switch of 1

ampere to the 380 V mains supply.

3. When maintenance or cleaning work is being done, the machine must be shutdown and the

mains plug pulled out.

4. Do not brake workpieces or chuck by hand or any other objects.

5. Wear safety goggles when working the machine.

6. Do not remove the chips with the hand. Use corresponding aids (hand brush, hook, paint

brush).

7. Always keep the protective hood on the driving mechanism closed.

8. The turning tools must be firmly tightened at the correct height and as short as possible.

9. The turning tools must never be exchanged when the machine is running.

10. Never leave the clamping chuck key in (even when not in operation).

11. Observe the bearing distance of the turning chuck. (Turning jaws max. 40mm ∅, Drilling jaws

max. 100mm ∅).

12. Never take measurements on work pieces being turned (danger of accidents and damage

to the measuring gauges)

13. Do not wear loose items of clothing (ties, shirt sleeves, jewellery etc.).

14. When working between centres, always centre well in order to avoid a flying-out of the

workpiece. In addition, check the tightening screw of the tailstock to make sure it is tight.

15. When working with automatic advance take care that the cross table does not touch the chuck

or the tailstock.

16. Never leave the machine when in operation.

17. When turning wood, use the lathe centre fort he slaving of the work piece instead of the

lathe chuck.

18. The machine must be secured so that it cannot be swichted on by children. Make sure that

other people do not come in contact with the machine.

19. The machine must be kept dry at all times.

20. Check the machine frequently for damage. Any damage parts must be replaced with original

parts and should be fitted by an expert or by us.

27

8. Startup and Maintenance

8.1 Electrical equipment

The lathes are fitted with a master switch w ith undervoltage release, i.e. this switch must be

switched on before the machine can be switched on via the reserving switch. The master switch
must also be switched on again following a power failure.

All lathes can only switched on with closed plexiglass bonnet.

If you want to change the turning direction through the switch right-left the switch must stay for 1
sec. on 0-position for the reason that the relay of the potentiometer has enough time to react.

8.2 Start up

i

Prior its putting into operation the machine must once more be cleaned with
great care. All lubricating points have to be furnished with grease while the
cross slide, the threaded spindles, the guide bars and the quill are thoroughly
oiled.
Turn by hand all spindles in order to check for their smooth turning.
Run in the lathe with the lowest possible rotary speed being switched on. A
full load to start with must be avoided!

8.3 Maintenance

The longtime serviceability is vitally dependent upon a corresponding serving attendance. The lathe
needs to be cleaned after every turning job.

i

In case the lathe is being erected within a moist cellar, all naked parts need to
be oiled after completed usage to avoid corrision.
An overall and constant lubrication of all moving parts is highly signeficant.
In case backlash within the bearings or within the guideways of the slides
should occur, readjust in time to avoid the bearing or the guideways of the
slides being destroyed.

28

8. Startup and Maintenance

8.4 Lubrication

Prior to every putting into operation all lubricating points of the lathe must receive a grease for roller
bearings having commercial quality.

Both guiding bars have to be greased, too, preceding every putting into operation. The two dovetail
guides of the cross slide, the threaded spindles of the cross slide accessible from below, the feed
rod as well as the tailstock quill have to be greased at intervals of 100 service tours each using
lubricating oil.

When greasing make sure to put the slide of the cross slide to its hindmost position while extending
the tailstock quill to its foremost posision. Greasing the tailstock spindle is performed via the hollow
borehole within the quill.

3. adjustment tighten the counter nuts again.

Longitudinal slide:

The longitudinal slide rest is mounted on the transverse slide rest and can be pivoted through 360°
degrees. Thus, it is suitable for the turning of tapers. For adjustment, the 4 mm Allen key is used
to loosen the two screws located on the outer sides of the transverse slide rest. The arrow on the
transverse slide rest. There is a scale of the degrees on the longitudinal slide rest. The distance
between two graduation marks represents one degree.

Scale rings:

To set the turning tools, the slide rest spindles have graduation collars with graduation marks. One
graduation mark represents a 0.05 mm feed adjustment which corresponds to a 0.1 mm chip
removal on the work piece.
The hexagon socket screw is provided for cases where the compound rest is to be fixed to the slide
bars (e.g. in the case of transverse turning.) It screws down the clamped piece at the lower side of
the transverse slide rest against the two slide bars.

8. Startup and Maintenance

8.8 Tailstock

The tailstock is attached to the slide bars in such a way that it is slidable. It can be easily tightened
in any position by screwing the lower T-handle (4251). It can be separated into barrel and base. By
loosening the spanner bolt (424), the tailstock barrel can be pushed to either side by up to 10 mm
and is, therefore, suitable for the turning of slight tapers. After completing the taper work, the
tailstock is to be returned to its original position.
The central position of the tailstock is indicated by the mark on the side. By making a trial turning
operation establish whether the working piece is cylindrical and if necessary correct the position of
the tailstock.

Solid tailstock sleeve:

The solid tailstock sleeve, which is provided with a millimetre scale, is designed in such a way that
the lathe centre, drill barrel or chuck are automatically ejected when turning back.

Tool clamping:

An inner cone MT 2 which is worked into the tailstock sleeve serves to accept the tools. By
screwing the upper T-handle (4251), the tailstock sleeve can easily be clamped in any position. The
tailstock sleeve can be moved axialy over a threaded spindle by using the crank (31212) located at
the rear end.

9. Speed regulation

9.1 Speed selection

The spindle speed is to be selected according to the type of material and the diameter of the work
piece:

Small diameter

⇒

relatively high speed

Large diameter

⇒

low speed

The cutting speed is the result of speed and diameter.

With a known and required cutting speed, the necessary spindle speed can be calculated in the
following way:

Example: An aluminium workpiece which has a diameter of 20 mm is to be turned

with a cutting speed of 100 m/min.

Now, from those speeds available, the one is selected which is nearest to
the ideal speed of 1592 1/min. (in our case 1600 1/min.).

Applications

10.1 Longitudinal and transverse turning

Longitudinal turning:

In the case of longitudinal turning tool moves parallel to the axis of the workpiece. For roughing at
longitudinal turning the use of either a straight or arcuated turning tool is favourably.

Transverse turning:

The tooling of the face is known as transverse turning. In the case of transverse turning, the turning
tool is moved at 90 degrees to the turning axis of the piece being turned. In so doing the compound
rest is to be locked. The main cutting edge of the turning tool is to be exactly centred so that no scar
remains in the middle of the workpiece. The arcuated tool is used for transverse turning.

1

to 1+2: Roughing tools arcuated to the left and or right: By using them a maximum on

material is to be cut off in as short a time as possible (without paying attention to the
finish on the surface of the work piece). They can be used for longitudinal and transverse
turning.

to 3: Offset side turning tool: Used for smoothing (clean surface) in the case of longitudinal

and transverse turning.

to 4: Outside thread turning tool: Used for cutting of outside threads.
to 5: Narrow square-nose cutting tool: Used for the cutting of grooves and slicing of

workpieces.

i

When inserting the slicing tool No. 5, pay careful attention to the exactness
of the centre height of the turning tool. Work with low speed and cool the
tool (use soluble oil or emulsion for cooling: serves to lubricate and for the
removal of chips.) The slicing tool is to be clamped as short as possible and
at 90° degrees to the workpiece.

to 6: Right side tool: Used for the hollowing-out of boreholes. Clamp as short as possible in

order to avoid ascillations of the turning tool which might otherwise occur (uneven
surface).

Applications

10.1 Longitudinal and transverse turning

i

For the reason of the power at the turning chisel take care that the tool is short
and fast fixed. If the lever arm is to long the turning chisel curves and springs
back. The cutting part enters uneven into the workpiece and is producing a
waved surface.
Take care that the turning chisel is placed on the middle of the turning piece.
The control of the height position of the middle of the workpiece is done w ith the
live lathe center in the tailstock.
For the regulation of the height position of the turning chisel use with straight
sheet steel pieces.

10.2 Thread cutting and automatic feed

10.2.1 General note

The tread turning chisel is a form turning chisel with the profile of the thread to be cut.. It is ground
according to jigs (diagram 1) and must be adjusted exactly to the middle of the workpiece as,
otherwise, the profile of the thread would be distorted.

In order to obrain the correct position of the flanks of the thread to the axis of the workpiece, the
grinding jig is put against the work piece and the turning tool is adjusted in accordance with it
(diagram 1). For this purpose the jig is pushed successively on to both flanks of the turning tool.
The feed of the thread turning tool is effected over the lead screw and must correspond to the
thread pitch.

Setting the thread turning chisel

90°

Change gears:

The connection between the feed gear mechanism and the lead screw is made by the translating
gear wheels (extras at D2000, D2000E and D2400) included in the attachments. By setting various
combinations of gears it is possible to cut a metric right-hand thread with a pitch of 0,4 mm - 3 mm
and an inch-system right-hand thread with a pitch of 10Z/1" - 32 Z/1" (see table). (For left hand
threads see the section "Gear pair, left-hand thread"). The various distances of the axes between
the gears can be adjusted by swiveling the quadrant and readjusting the quadrant bolts.

36

10

.

Applications

10.2.1 General note

Feed:

The feed is switched on by means of the T-handle on the front side of the spindle head.

i

When cutting threads it must be remembered that the feed remains on
throughout to ensure that the turning chisel always returns to the same
positon when cutting more than one thread. For this reason, after completing
the cut the turning chisel with the transverse carriage is cammed out as,
otherwise, the flanks and cutting edges could be damaged and is returned to
its original position by altering the turning direction of the motor over the
reversing switch. It is advisable to make a 4-5 mm wide grove at the end of
the thread in order to enable a better camming out of the threading tool.

Long thread:

In the case of long thread diameters, the revolving lathe centre should always be used in order to
prevent the work piece from being pushed away.

Overload clutch:

To avoid damage at the advance system the main spindle and the leading spindle drive are
connected with an overload clutch.

10.2.2 Application of change gears - optional for D2000 and D2400 E

For the purpose of automatic longitudinal turning there are two feed rates, being at your disposal:
0,085 mm and 0,16 mm/revolution. (Upon delivery, the gears producing a feed of 0,085
mm/revolution have been put on).

Putting on different combinations of gears enables you to cut metric thread ranging from 0,4 to 3,0
mm in pitch. The same applies to inch thread ranging from 10 threads/" to 32 threads/" in pitch.

are effected with the angle plate from the workpiece.
If the angle plate is correctly mounted on the
compound rest (see assembly instructions), the
workpiece can be rigidly and firmly attached to the
clamping plate. This should be cleaned of dirt and
chips beforehand in order to guarantee a good rest.
The clamping screws used are inserted into the T­groove of the clamping plate. In addition, a machine
vice can be attached to the clamping plate. The tool is
to be clamped as short as possible in the collet chuck
(danger of breaking). If the tool is firmly clamped, the
depth adjustment can be made over the feed shaft.

Assembly of the angle plate with the milling table
At first you remove the longitudinal slide rest from the transversal slide rest of the lathe. Then the
angle is screwed on to the carriage of the transversal slide rest with the delivered hexagon screw.
After removing the clamping plate and the spring from the longitudinal slide rest you fix the
longitudinal slide rest as indicated against the clamping angle.

Three jaw-chuck and four jaw-chuck

The three-jaw chuck

serves to clamp circular, triangular and hexagonal workpieces centrically to the spindle axis.

The four-jaw chuck

serves to clamp square workpieces centrically to the spindle axis.

i

Danger of accident

Do not try to clamp larger workpieces. The chucking power is then too low
and the jaws can detach themselves.

Mounting of turning jaws:

The jaws and guides are numbered from 1-3. Open the chuck by means of the chuck key until the
jaws loosen. (order: 3, 2, 1 bzw. 4, 3, 2, 1).
Now, take the inner jaws beginning with the number 1 and put this in the guide number 1. Push the
jaw number 1 in the direction of the centre point of the chuck and at the same time turn the chuck
key (direction "tighten"). When the transverse spiral has taken hold of number 1, number 2 must be
put in the guide provided. The same now happens to number 2 as to number 1. Proceed with
number 3 and number 4 in the same way. Subsequently, examine the position of the jaws.

Mounting of drilling jaws:

If, afterwards, you again want to work with outer jaws, the process repeats itself in the same order
(first jaw 1, then 2, then 3, then 4).

.

Collet chuck

Mounting of the tool holder:

When working with the collet chuck, the concentric chuck must be
removed from the workspindle. In order to do this, loosen the three
tightening screws by means of the Allan key SW6 included in the
accessories. Now, the chuck can beremoved from the concentric
flange of the workspindle and the collet chuck can be fixed in the
same way as the lathe chuck.

Collets:

Then press the collet into the union nut and screw it on the collet
chuck.

i

Only those workpieces may be used which accord to the nominal diameter
of the collet chuck.

Steady and follow rest

Steady and follow rest compensate for the deflection of long shafts caused by resultant
cutting forces. The roller jaws of the rests prevent the pieces to be turned form deflection.

They are to be adjusted in such a manner that the turning axis of the workpiece is in true alignment
with the height of the centres of the machine. At the point of support, the pieces to be turned must
be completely round.

Steady rest:

The steady rest can be firmly clamped to any
position on the slide bars. It is put on the slide
bars with its half shells and fixed to the slide bars
by means of the clamping plate.

Follow rest:

The follow rest is used particularly for turning thin,
long shafts and for turning threaded spindles. It is
screwed firmly on to the threaded drilled holes of
the compound rest provided for this purpose, so
that it holds the workpiece as near as possible to
the turning tool.

16

.

Square turret head

The square turret head is used instead of the clamping plate in order to clamp the tools.

Four turning tools can be changed simultaneously. By swivelling the turret head by 90 degrees
each time, the required turning tool can quickly be brought into its working position

There are four centering holes on the bottom for
securing the square turret head in its four
positions. For this purpose, the screw supplied
with the springmounted steel ball must first be
screwed into the threaded hole in the upper part
of the turning carriage.

Hand tool rest

for turning wood

Die Handstahlauflage wird auf die Führungsstangen der Drehmaschine montiert.
There are two alternative adjustments:

1. By loosening the lower part by means of the

knurled screw, the hand tool rest can be adjusted to
any position or be swivelled to the workpiece.

2. By loosening the upper part by means of the

knurled screw, it can be centred or by
corresponding turning adapted to match the shape
of the workpiece.

i

To avoid accidents during operating with chisels on the hand steel rest and the
fixing of the workpiece into the chuck please use for wood turning the fix lathe
centre.
To avoid accidents, the hand tool rest is to be pushed as near as possible to the
workpiece and readjusted in the course of machining.

Wood turning lathe centre

The wood turning centre serves to accept w orkpieces out of w ood between the centres and
enables a machining of the piece throughout its entire length without any reclamping being
necessary.

It is contained in the inner taper of the workspindle. Pay carful
attention to cleanliness when inserting the wood turning lathe
centre since dirt or metal chips could damage the taper. By
feeding forward the tailstock sleeve to the workpiece and the
cutting edges of the turning lathe centre are pushed into the
front side of the workpiece. The correct degree of pressure
depends upon the firmness of the workpiece, the diameter and
the cutting section (chisel advance).

Unit for lubrication coolant

The unit for lubrication coolant consists of:

1. Tray with lubrication coolant sump which collects the lubrication coolant mixture for the feed pump.

Contents generally 19 litres.

2. Feed pump with the following electrical data

- nominal voltage 230 V

- frequency 50 Hz

- nominal current input 0,4A

- nominal output 0,07 kW

- ON-OFF switch and mains lead with a length of 2 m complete with earthed plug.

3. Adjustable, felxible pressure tubing with stop valve and nozzle for transporting the lubrication

coolant to the processing point.
An increasing number of customers wish to include this fixture in their order so as to take
advantage of “wet processing” for the production of their goods / workpieces and to:

- to cool and lubricate, in particular during lengthy processing

- when processing high alloy stell an aluminium

- to increase the tool life

- to inporove the surface finish and accuracy of the workpieces

- to reduce friction heat

- to prevent built-up edges

When using lubrication coolants, especially water based emulsios, a number of health and safety
measures must be observed, which we would like to recommend as follows:

1. Use concentrated products free of nitrates.

2. Use concentrates without secondary amins.

3. Use products with the lowest possible allergy potential.

4. When mixing a refill of lubrication coolant, please observe the following:

-clean / rinse the circulation system (tray / filter)

-determine the concentration necessary to meet the technical demands
(concentrate: water 1:5 – 1:30)

-check the water has a low level of nitrates (< 50 mg NO 3-, test strip)

5. A cleaning plan should determine at what intervals the system should be cleaned of swarf and

other waste.

6. A service plan should determine the following.

-when to check the concentration in use (daily / weekly)

-when to check the pH values (weekly)

-when to check / assess the bacteria count (monthly)

-when to check the nitrate content (weekly)
(The information in brackets can be varied according to the production circumstances.

7. In order to reduce splashing, we recommend the attachment of a splash guard and / or reducing

the amount sprayed from the nozzle.

8. Since steps to protect the skin must be taken, it is advisable to wear gloves and aprons. The skin

sould be cleaned with acidic syndets without abrasive ingredients and rich cream should be
applied to regenrate the skin.

9. Please also take note of the enclosed information on the general operating instructions.

Declaration of noise levels in accordance with

DIN EN 24871 (German Industrial Standard)

Noise levels while running idle

Acoustic capacity level 67 dB (A)
Sound pressure level on operator’s ear 63 dB (A)

The stated values reflect emission levels and not necessarily working levels. Although there is a
correlation between the level of emission and the level of stress, this cannot be used reliably in order
to determine whether additional safety measures are necessary or not.
Other factors which influence the actual stress level or employees are the characteristics of the
working area, other sources of noise, i.e. the number of machines and other processes going on
nearby and so on. Apart from that, the permitted stress levels may vary from country to country. This
information is to allow the user of the machine to assess the dangers and risks more accurately.
