The bed is made of a high-grade low vibration cast iron (FCD25). By combining high sidewalls with strong cross ribs, a bed of low vibration and rigidity is produced. The two precision ground V-sideways are an accurate guide for the support and tailstock. The main motor is mounted on the rear of the bed.
The headstock is cast from a high-grade low vibration cast iron. It is bolted to the bed, using four screws and four adjusting screws for alignment with the head. The large main spindle is mounted on two precision taper roller bearings (#7212). The hole of the spindle measures 35 mm. A quick change of the belt can be accomplished by easing the tension on the idler. The belt type used in this lathe has the advantage that it makes no noise at any speed.
The bed slide is made from high quality cast iron; the sliding parts are smooth ground. It slides over the bed without play and can be easily adjusted. The cross slide is mounted on the bed slide and moves on a dove tailed slide. Play in the cross slide may be adjusted by means of the wedges. Use the hand wheel to move the cross slide. A graduated collar is placed on the hand wheel; one graduated mark equals 0.0254 mm. The tool slide is mounted on the cross slide and can be rotated 360º. The tool and cross slide travel on dovetailed slides and have wedges, adjustable nuts and graduated collars. The four-way tool holder is mounted on the tool slide. For accurate results, tightening the hex nut can lock the support.
The apron is mounted on the bed slide and moves on a dovetailed slide. A half nut is fitted into the apron. The half nut gibes can be adjusted from the outside. The half nuts are responsible for the connection with the thread cutting axis. A gear shaft, moved by a hand wheel on the support, and a rack, which is mounted on the bed, achieve quick travel of the bed travel.
The tailstock slides on a V-way and can be clamped at any location by means of a bolt. A MT2 spindle with graduated scale is part of the tailstock. The clamping handle makes clamping of the spindle possible. By turning the hand wheel, the spindle can be moved.
5.6 Other parts
The lead screw is located on the front of the bed and is connected to the gear box on the left side. The gear box is made from high quality cast iron and is mounted on the left side of the bed. It is a 9-speed motor. Always change the speed to bring the idler in the right position. The motor is mounted on the rear of the bed.
Unpack the wooden crate and use clamping plates and ringbolts to hoist the lathe. Place the support and tailstock in a way that keeps the machine in the balance. When unpacking the machine, pay attention that the thread cutting axis, the spindle, the hand wheels or other protruding parts don’t get damaged.
All bright parts have been coated. Use kerosene to remove the layer of grease on all bright parts and the gear transmission before using the machine. Do not use paraffin, acetone or another solvent. Coat all bright parts with acid-free oil and grease, especially the slide ways. Warning! Lubricate the machine in accordance with the regulations before using the machine.
Place the lathe on a solid foundation with enough room for service and maintenance (fig. 2). Pour concrete around the foundation bolts after setting these in the accurate positions. After solidification of the concrete, place the machine on the foundation and tighten the foundation bolts (diam. 12 mm). Check adjustment with a spirit level in longitudinal and transversal direction.
6.4 Power supply Warning The machine must be connected to the power source by a qualified electrician. The power supply has to be connected by means of a separate connecting clamp. The electric wires are connected to the main connection at the rear of the headstock. Confirm that the power at the location is the same as the rating of the lathe before plugging the lathe in. The lathe must be properly grounded. The main motor turns clockwise (seen from the pulleys); the main spindle should turn counter-clockwise (seen from the tailstock). Exchange 2 of the 3 phases if the motor turns in the wrong direction (fig. 3).
The headstock is filled with Shell Tellus 32 oil. Remove the oil plug to change oil. The oil plug is located in the headstock (bottom left) and can be reached after removing the cover of the change gears. Check the oil level every week and change oil three months after using the machine for the first time. After that, change oil once a year.
7.2 Gear box
An oil bad with splash lubrication lubricates the gears and other parts. There is an oil reservoir located on the bottom of the gear box. Fill the reservoir with Shell Tellus 32 oil until the right level is reached. Check the oil level every week by looking through the oil-level glass and change oil three months after using the machine for the first time. After that, change oil once a year. To change oil, remove the oil plug located on the side of the headstock.
Fill the apron with Shell Tellus 32 oil till the right level is reached. Check the oil level every day and change oil three months after using the machine for the first time. After that, change oil once a year. To change oil, remove the oil plug located at the bottom of the apron. Oil is filled up by removing the filler cap at the right side of the apron.
7.4 Change gears
Lubricate the change gears once a month with machine oil or grease.
7.5 Other parts
Other oil supply points can be found at the levers of the gear box, the hand wheel of the apron, at the bed slide, cross slide, tool slide, cutting thread dial, tailstock, thread cutting axis and the feed shaft: fill up with oil once in a while. Lubricate worm transmission, half nuts en thread cutting axis twice a month. Coat the slide ways and all other bright parts, like the tailstock spindle, the feed shaft, etc. once a day with a small film of oil.
Use the coupling lever to select the turning direction (left/right) and to start the spindle. The spindle is not coupled in “neutral”.
9.2 Spindle speed 9.2.1 Starting position
• Check if the machine is lubricated. • The gear box and apron are activated when the main spindle turns. Make sure that the coupling lever is in neutral and the feed direction lever and the half nut lever are both disconnected. Now, the longitudinal (10) or cross hand wheel can be turned manually.
Use the coupling lever to select the turning direction.
9.2.3 Selecting speed range of main spindle
Choose the speed range by means of speed switch high/low and a lever with four positions. The four speeds (in the high/low range) are displayed on the machine shield. Put both levers in the appropriate position for the requested speed. Warning Only change the speed when the spindle has come to a standstill!
9.2.4 Starting periode
It is recommended not to use the highest speeds when starting the machine for the first time. Proceed as follows: Select a low feed speed and load the machine lightly, during 3 hours, at 460 RPM, then 2 hours, at 755 RPM, then 1 hour, at 1255 RPM. Follow this order when putting the machine into operation. Note: If not used, disconnect the pin of the thread cutting dial from the thread cutting axis to avoid wear.
9.2.5 Hole through spindle Camlock DI-4” Install jaw chucks, catch plates and other tools that are mounted on the spindle: • check if the hole and the surface are clean, • check if all camlocks are open, • install the tool on the hole through the spindle and attach all camlocks (turn clockwise). Mark off a reference line on the tools, in the extension of the reference line on the hole through the spindle. This makes clamping a tool again much easier. Note: For correct locking condition, each cam must be tightened with its index line between the two “V” marks on the nose. Warning Do not interchange chucks or other attachments without checking each cam lock for correct locking!
9.2.6 Adjusting the camlock Figure 4 Remove lock screw (B). Turn bolt (A) once in or out as required. Tighten lock screw. Note: Each cam lock has a reference sign (C) to indicate the original setting.
9.3 Thread and feed selection
All available feeds and threads are adjusted by using the charts that can be found on the front of the cover.
9.3.1 Manual operation
The hand wheel is used to move the bed slide. The cross slide is moved by means of the hand wheel, that is fastened on top of it, and the tool slide by using the hand wheel of the tool slide. The bed slide can be locked, by turning the tightening nut clockwise.
9.3.2 Replacing the change gears
Remove the cover, loosen the hex nut of the locking bolt and. After that loosen the locking bolt of the suspen-sion to replace the transmission gear. The drive gear can be replaced after loosening bolts 120 T and 127 T.
9.3.3 Automatic feed operation
First, engage the lever for the feed direction and install the change gear 30 T on the transmission shaft and change gear 127 T on the drive shaft. Turn the selector handle for feed/thread cutting counter-clockwise. Put the handles of the gear box in position 1-8 e.g. A-E, to enable the feed shaft to turn. When the handle for the feed shaft is pulled out and pushed upwards, longitudinal feed is achieved. By pushing the handle in and downwards, cross feed is achieved. The feed direction is selected by using the handle on the headstock. There are 40 different speeds available for longitudinal and cross feed. Choose the speed by moving the handles of the gear box.
Connect the thread cutting axis by moving lever for selection of feed/thread range to the right and the lever for thread cutting downward. The transmission (longitudinal travel) for thread cutting is obtained. The direction for thread cutting is selected with the switch on the headstock. The desired thread cutting is selected by means of the handles on the gear box.
9.5 Thread cutting dial
The thread cutting dial is located on the right side of the apron and is used for thread cutting with the lead screw. For an even thread, close the half nut at the desired line of the dial, for an odd number on a numbered line. The thread cutting dial should stand on the same spot at every cut. To avoid wear, it is recommended to disconnect the pin of the thread cutting dial from the lead screw if not used.
9.6 Cross slide and tool holder
A tool holder is mounted on the tool post. The upper part contains a 0-450 left/right scale. The vernier scale on the hand wheels correspond with the type of machine (Metric or Whitworth).
The tailstock is used to produce small parts. It can be adjusted transverse by using the set screws, that are mounted on both sides of the tailstock. First, make sure that the locking lever of the tailstock is loosened. Loosen the screw at the back. First, loosen one set screw, than the other, until the desired position is obtained. Tighten both screw and the locking lever. The tailstock pinole can be tightened with the handle.
When the lathe is installed and ready for use, it is recommended to check the machine alignments before commencing work. Alignment and levelling should be checked regularly to ensure accuracy. The V-belts can be reached after removing the back splashguard, the cover and the V-belt guard cover. The motor is mounted at the back of the bed on a plate that can be adjusted vertically. The plate is clamped with two stay bolts and nuts. The belt tension is adjusted by turning the two hex nuts at the top of the plate outwards. Check the pulley settings by putting a builder’s level over the pulleys. Make sure that the pulleys stay in line. Use the hex screw on the bottom side of the tailstock between the guides to adjust the locking lever of the tailstock. Adjust the transverse guiding by adjusting the tapered key with the slotted bolt at the front of the cross slide. First, loosen the bolt at the back of the cross slide and tighten the bolt on the front by turning clockwise. Tighten the bolt at the back after making the adjustments. Follow this procedure to adjust the guide of the tool slide, only now use the slotted bolt on the front of the tool post. Wear of the cross bolt can be compensated: Remove the protection plate at the back of the cross slide. Turn the hand wheel of the cross slide clockwise until the end of the cross spindle is reached. Turn the bolt at the end clockwise, as far as needed. Do not over tighten the bolt: a rotation of 45° matches a play of 0.125 (.005”). The spindle bearing has already been adjusted. The right setting is 0,0050 mm (0,0002”), the spindle can still be moved by hand. Technical changes and developments can lead to small deflection in the specifications and descriptions above. This also applies for the part lists and drawings.
This manual starts with a part which mainly deals with general specifications of the Sino digital readout, safety instructions and symbols. After that, the manual deals with all functions and operating instructions for the Sino digital readout when used on a lathe.

7.6 Error compensation seGmenteD error compensation (seGment) Attention! Segmented error compensation can only be used when millimeters are displayed. There are two way to use segmented error compensation: ▪ Starting point as source (fig. 1) ▪ Absolute zero as source (fig. 2)
L = Total distance L1 = lenght of compensation segment L2 = effective distance of compensation segment
Move to the smallest value. Switch to absolute mode. Select the axis. Enter the number of segments and confirm. In fig. 1 In fig. 2
Enter the segment lengths and confirm. Find the mechanical origin. There are two options: 1. Choose the actual position as origin. 2. Choose the first absolute zero of the encoder as origin. Enter the correction factor of segment 1. Move the slide for the X-axis in positive direction.
If the encoder has moved over the total length of the correction factor, the display on the Y-axis is dimmed and a new value can be entered. The Y-axis will display the value of the X-axis. This means that the compensation factor has been stored. Enter the value of segment 2.
Enter the value of segment 3.
Enter the value of segment 4.
Enter the value of segment 5.
Enter the value of segment 6.
Close. Cancellation of segmented correction factor Proceed as follows: Follow the method as described above. In every case when a number of correction factors have to be entered, enter the value of 0 to cancel. Alle stored values will now disappear. Finding the function of mechanical origin The mechanical origin has to be found again when the encoder moved, or in case of power loss or deactivation of the digital readout. The display will show incorrect values if the mechanical origin can not be found again. The starting point is regarded as mechanical origin. Proceed as follows: 1. Move the encoder to the position that was the original mechanical origin and select segmented error correction. Do not enter a number of segments or the length of them. Press to skip. 2. Select the mode to choose the correction method and press . The readout will select automatically. 3. Press immediately to end the setup of the error correction.
Attention! Linear error compensation may only be used in absolute mode (ALE) and with millimeters displayed. Linear error compensation allows the operator to apply a constant correction factor to all measurements displayed. The further away the encoder is mounted from the centre line of the workpiece, the greater the potential for linear error is. Linear error correction is expressed as a multiplier, which is displayed for each axis. Compensation factor = (true distance–measured distance) / (true distance/1000) mm/m Correction range: -1.500 mm/m~+1.500 mm/m Example: the actual length of the machine table measures 1000 mm, the display shows 999.98 mm. This means: Coefficient last used Compensation factor = (1000 – 999.98) / (1000/1000) = 0.02 mm Select the X-axis. Display in inches. Enter the correction factor.
7.7 Sleep mode
The switch on the rear of the display can be switched off during operation. Even though the display has a memory, in which in case of power loss all data is stored, it is still possible that the tools during power loss have been moved. Therefor, after switching on the display again, the actual situation is not displayed correctly. To avoid this problem, it is advised not to switch off the display but to use the Sleep function. Attention! The function Sleep is only available if the display is NOT in absolute mode. Proceed as follows: 1. Press . Display is dimmed. 2. When resuming work, press
, all data becomes visible again.
DurinG power loss
When a power loss occurs during operation or when then machine is switched off, then the display will automatically store the operating status (for example the values displayed and the linear compensation factor). The display will perform a self-check first after the power has come on again. After that, it will return to the spot were it left off and operation will be resumed from this position on.
This function only works in absolute mode (ALE). Only then, fixed co-ordinates can be entered. ALE is the reference system. All entered co-ordinates (UCS) entered by the operator, are defined in regard to ALE. Up to 200 different sub datums (SDM) can be entered and stored. When processing moulds for example, more than one reference point is needed. The more complicated the work piece, the more reference points are needed. A lot of time is won when UCS are entered before operation begins. Every extra SDM equals the co-ordinates of 1 tool as entered by the operator. The SDMs are stored as co-ordinates in regard to the absolute zero. If the absolute zero is changed, the SDMs change as well. Proceed as follows: 1. Select absolute mode. The first entered zero point is the most important SDM of the work piece (point 0 in the figure). Enter other SDMs on the co-ordinates of the tools (points 1, 2 and 3 in the figure). 2. You can use special functions when the SDM is displayed. SDMs are stored by using on of the following two methods: Method 1 Use a reset when a SDM is reached. Press
40 3( 20, - 130)
Method 2 Use the image as a reference. Switch on the machine and move the tool to point O. Select absolute mode.
O( 0, 0)
1( 20, - 70)
2( 30, - 120)
Place the zero point of the tool in the absolute mode on the SDM of the tool. Zero both the X- and the Y-axis.
The unit automatically stores the data. Use UCS. There are 2 ways to do this: 1. 2.
Enter the co-ordinates of the first SDM. Enter the position of the next tool.
The direction of the co-ordinate of the entered SDM’s in the example as mentioned above, equals the opposite of the result on the display. If a co-ordinate of a SDM in UCS-mode is entered on the position of the zero in absolute mode, then the display will show the position of the absolute zero, because in UCS-mode, every SDM is seen as the origin of the UCS. In fig. 1, position O in regard to position 1 has co-ordinates (-20, 70), in regard to postion 2 (-30, 120) and in regard to position 3 (-20, 130). If the operator enters the co-ordinate of a SDM on another position than the absolute zero in the absolute mode, than the display will show the position of this point in UCS-mode. Using subsidiary reference points Open the mode to enter reference points by pressing or . In case the arrow keys are used, please press them continuously until the desired menu option is reached. Only pressing will lead to the message “Zero no”. Enter the number of the reference point here.

155 The workpiece is processed in coarse way. Fine processing is needed now. The play for coarse processing measures 0.05.
Set the absolute co-ordinate on position A. Use Method I to set the SDM’s. The first co-ordinate is (10, -40), the second (20,05, -70) and the third (30.05, -120). Check the tool. Start entering. Enter the code.
Process Ø 20. Start processing until the displays of both Xand Y-axis show 0. Enter the second co-ordinate. Proces Ø 40. Start processing until the displays of both Xand Y-axis show 0. Enter the third co-ordinate. Process Ø 60. Start processing until the displays of both Xand Y-axis show 0. Return to the absolute mode. Keep pressing the arrow key, until ALE is displayed. Turn the tool to the other side, the other Ø 40 can be processed. Erasing reference points Press in absolute mode 10 times on
, all entered co-ordinates will be erased.
Reset of reference points It is possible during an operation to enter a new co-ordinate. When resetting, the point on which the reset started will become the new reference point. Use ½ when using an extra reference point 1 can be used when the operator enters a reference point. It also leads to a reset of the reference 2 point. This will ly between the old and the new reference point. 13
Use this function to enter tool offsets for different tools. The operator can now use different tools, without having to change the absolute zero or reference point. By using this function, the movement stays consistent when changing the tools. 10
2. Place the next tool (2) in regard to the reference tool. The relative position of the second tool will be: X-axis: 25 – 30 = -5 Y-axis: 20 – 10 = 10 3. Assign a number to the tool and store this into the readouts memory. 4. Repeat steps 2 and 3 for every other tool.

(due to deterioration and / or obsolescence) General rules If the machine is to be permanently demolished and / or scrapped, divide the material to be disposed of according to type and composition, as follows: 1. Cast iron or ferrous materials, composed of metal alone, are secondary raw materials, so they may be taken to an iron foundry for re-smelting after having removed the contents (classified in point 3). 2. Electrical components including the cable and electronic material (magnetic cards, etc) fall within the category of material classified as being assimilated to urban waste according to the laws of your local state, or federal government, so they may be set aside for collection by the public waste disposal service. 3. Old minerals and synthetic an / or mixed oils, emulsified oils and greases are considered hazardous or special refuse, so they must be collected, transported and disposed of at a special waste disposal service. Attention The standards and legislation concerning refuse are subject to change. The user must keep informed of the regulations at the time of disposal as they may differ from those described above.
