5.13 Transmission system
AC servo motors are used in the three coordinate axes and spindle.
Feed system working principle
The feed drive mechanism drives table (X), carriage (Y), spindle head (Z) to realize
X/Y/Z axis feed motion and positioning via servo amplifying unit, servo motor and ball
screw after receiving instruction from the CNC system. See Feed system schematic
diagram:
Page 45 Total 72
Page 51
Instruction manual Document No.: VM50-9302E
The drive methods of the three coordinate axes are the same: servo motor is
connected to lead screw via non-clearance elastic coupling that is connected to motor
shaft and lead screw shaft without key, which features easy disassembling and good
concentricity. High speed ball screw is used and pre-tensioned when installed to raise
the accuracy stability and rigidity and ensure the moving accuracy.
The feed system uses semi-closed loop control system. The angle displacement
measuring device in the servo motor detects the displacement of the moving part
indirectly by detecting the rotation angle of motor shaft and feeds the data back to the
comparator that compares the data with the instructed one. The difference of
comparison is used to control the moving part and supplement the displacement until
the difference is in the allowable range of the control system.
5.14 Tool magazine system
5.14.1 Tool magazine outline drawing
Page 46 Total 72
Page 52
Instruction manual Document No.: VM50-9302E
5.14.2 Tool magazine working principle
Tool magazine drive system, including tool magazine, manipulator, etc. is used to
realize the tool change of the machining center. When the CNC system sends out the
instruction, tool change will be carried out automatically.
The indexing and tool change motion are realized by cam device. For details,
seeing the Tool Magazine Instruction Manual.
Tool magazine can hold 20 or 24 tool, tools are managed by PMC（Programmable
Machine Controller）. Tool needn’t coding and switch and tool is selected in sequence.
Every tool has a fixed tool station and is set by the operator. If the tool station or station
number is changed, it should be reset in CNC. For safety reasons, spindle tool number
is set 00, that is to say spindle has no tool. The tool to be machined is placed in each
station.
Like axis, tool magazine also has reference point. When machine tool is powered
off, or emergency stop button is released, execute tool magazine return to zero position
and then tool station No. 1 (T01) is in the tool change position. Tool change is divided
into two circumstances: spindle has tool and spindle has no tool. In the former
circumstance, the tool station to be changed is the xx tool before tool magazine acts;
while in the latter circumstance, the tool station to be changed must be empty, that is to
say that it corresponds to xx tool station number of xx tool number in spindle. For safety
reasons, move X-axis in the negative limit position and Y-axis in the positive limit
position when spindle orients in tool change process.
Tool change sequence: spindle move to tool change point → tool magazine find
tool → tool pocket overturn → ATC seize tool → spindle unclamp tool → ATC draw tool
→ spindle huff → ATC turn and change tool → ATC load tool → spindle clamp tool →
ATC back to zero position→ tool pocket back to original position

5.15 Spindle transmission
5.15.1 Spindle transmission principle
The power is transmitted from motor to spindle via a synchronized toothed belt.
To replace the transmission belt, the specification and supplier of the product
should be the same with the original one. The steps to replace the belt is as follows:
take down the connecting air pipe of the cylinder → take down pneumatic cylinder →
take down cylinder rest → replace belt → install cylinder rest → install pneumatic
cylinder → install the connecting air pipe of the cylinder → tension the belt. For the
spindle head assembling schematic diagram,see the following picture.
To tension the belt, loose the two adjusting screws, move the spindle motor plate
and then lock the nut in the plate. If the belt is too tight, the load to the spindle bearing
will increase and the service life of the tool will be reduced. Guard against oil or dirt
when replacing the belt.

5.17 Lubricating system
5.17.1 Lubricating of guide ways
The lubricating oil is supplied to the moving parts by the lubricating pump at fixed
time and quantity to lubricate the three coordinate guide way surface: base—carriage
guide way surface, carriage—table guide way surface, spindle head—column guide
way surface and lead screw nut. When the machine tool is powered on, lubricating oil
pumped by the lubricating pump at a reduced speed inpours into every lubrication
points and ball screw nut. The timing lubricating device is equipped with oil level switch.

Choose the lubricating oil with approximate viscosity as season and temperature
change. The oil with low viscosity will result in the malfunction of exhaust valve. It’s
recommended to use 68# hydraulic guide way oil.
5.17.2 Utilization of high speed grease
Quantitative NBU15 high speed grease, which is able to endure abrasion and
temperature rise and won’t flow away in high speed, is filled in the spindle bearing and
lead screw bearing. User needn’t replace it until overhauling the machine.
5.18 Cooling system
5.18.1 Workpiece cooling and chip removal
The cooling system of this machine covers：chain type chip conveyor and cooling
tank. The chain chip conveyor collects metal chips automatically and helps the machine
operator to work a lot easier. The coolant tank is to be filled with mineral oil or
emulsified mixture. The coolant is pumped to the column then to the spindle hose and
sprays through the nozzle. The flow is adjustable by turning nozzle spray and valve.
The coolant gone through workpiece flows to the coolant tank to be recycled by
deposition. The coolant pump is operated and controlled by the buttons on the control
panel or processing codes.
Coolant through outlets are placed around spindle nose. The pump is controlled by
the buttons as well as controlled by M code in the program for easier cooling. Each
sprayer is operated by ball valve for flow and direction adjusting. Chip removing pipes
are situated at the bottom part of the machine，6 sprayers work for this purpose with
high pressure to enable the chips be flushed away quickly and cool down workpiece so
that the thermal deformation in the workpiece is avoided. Chip removal pump is also
controlled by the buttons on control panel and by M code.
5.18.2 ZF gearbox cooing (optional)
When the machine is equipped with a ZF gearbox, it is necessary to add a ZF
Page 55 Total 72
Page 61
Instruction manual Document No.: VM50-9302E
gearbox cooler. The cooler cools down and lubricates the gears and bearings via
circulated coolant.
5.19 CNC rotary table(optional)
By using a rotary table, the machine can be 4 axes synchronically operational and
meet the requirements of machining with indexing rotation. If chuck and tailstock are
also equipped, circular and cylindrical parts could be processed. For example, helix
slots are workable under 4 axes function. CNC rotary table can be useful when the
workpiece need to be processed in multi-angle or multi-surface.
5.20 Utilization
The machining accuracy, efficiency and automatization of the machining center
depend on the quality of the mechanical part and the performance and stability of the
CNC system. Besides, in order to make full use of the machine tool, it’s essential to
have a full knowledge of the characteristics and machining technology of the machine
tool and use the machine tool reasonably. The following operating methods introduced
are for reference.
5.20.1 Operation
The most operation can be realized by pressing the keys and buttons on the
operating panel and control panel (For details, see Instruction Manual Electrical Part).
Only the following two kinds of operation should be carried out manually.
1) Unclamp the tool manually
In most circumstances, tool is loaded to the spindle by manipulator. In special
circumstances, it’s needed to load the tool to spindle by hand by pressing the button at
the right side of the spindle head in manual mode. (When the indicator light lights, the
tool is unclamped and vice versa.)
Note: The button is invalid when the machine is in machining state.
2) Tool magazine manual control
To facilitate the adjusting of the machine, a group of keys on the protective cover at
the lower right of tool magazine are designed for manual control of the tool magazine.
For the detailed operation, see Instruction Manual Electrical Part.
Page 56 Total 72
Page 62
Instruction manual Document No.: VM50-9302E
5.20.2 Select the workpiece for machining
The geometry and dimension of the workpiece should be in accord with chuck and
the travel of the machine tool. To raise the economic interest, consider the following
principles:
1) Small batch production when the workpiece is put into production repeatedly
To machine a workpiece by machining center, the time of prepared procedure such
as technology preparation, programming, etc. is long, but the tool, fixture, technologic
documents and program sheet can be repeatedly used. Therefore, when the workpiece
is put into production after test cutting, the production cycle and machining time will be
reduced dramatically.
2) The machining batch should be more than the economic lot size
Compared to the common machine tool, the flexible working time of a single
workpiece of a machining center is shorter while the adjusting time is longer, so it’s
uneconomical if the batch of the workpiece is small.
Machining Center Preparation Time –
Common Machine Tool Preparation Time
Economic = ———————————————————————————————————————
Lot Size K（Machining Time of a Single Workpiece
in a Common Machine — Machining Time of
a Single Workpiece in a Machining Center）
Thereinto, Machining Center Preparation Time = Technology Preparation Time +
Debugging time
Debugging time = Machine Tool Adjusting Time + Workpiece Program Test Run Time +
Test Cutting Time + Fixture and Auxiliary Device Validating Time
Here, only the adjusting time is part of machine tool starting time. For the
workpiece needing repeated production, the time of technology preparation and
program preparation should be divided by repeated production time. The machining
time of a single workpiece in a common machine is the summation of each NC
machining process time.
The compensation factor K should be at least 2, considering that the machining
center is much more expensive than the common machine tool. K should be larger as
the acquired skills improved.
1) Try best to do the integrated machining such as milling, boring, drilling, reaming,
tapping, etc.
2) The diameter of the workpiece for precision boring shouldn’t be more than 130
mm for the maximum tool change capacity of ATC device is 130 mm. To machine
the bigger hole, load and unload the tool manually or use circular interpolation
method to mill the hole, but the precision is lower.
Page 57 Total 72
Page 63
Instruction manual Document No.: VM50-9302E
3) The geometry and dimension of the machine tool should be in accord with the size
of table and travel.
4) Consider the balance of plant capacity.
5) The small but with complex geometry workpiece that is unable to be machined in
common machine tool or uneasy to obtain a stable machining accuracy.
5.20.3 Decide which part to machine
1) Before machining, determine which working procedure should be done in the
machining center and button down the relationship of the procedure and its last
and next one. For example, which kind of datum face and hole should be machined
before the workpiece is machined in the machining center and what working
procedure, allowance, etc. are left after the workpiece is machined in the
machining center.
2) Don’t use the machining center if other machine tool is more suitable and efficient
to machine the workpiece.
3) Decide whether to finish the machining once or twice in a single setup according to
the tool number needed and the requirement of workpiece accuracy and heat
treatment.
5.20.4 Compile the process chart
1) The format of the process chart is manifold. The user can develop an appropriate
format according to the production custom and need. The process chart is the gist
of program list, tool adjusting list and machine tool adjusting and the working
content of the operator.
2) Be familiar with the relevant stipulations of the use of machine tools
a) The setting of each coordinate origin, the direction of each coordinate axis, the
setting of workpiece coordinate system and the travel range.
b) Range of spindle speeds and S instruction.
c) Feed range and f instruction.
d) Tool and T instruction, tool change instruction.
e) Cutting criterion.
f) The working principle and instruction list of CNC system.
g) The machining characteristics and operating methods of the machine tool.
h) The approaching distance of tool (the distance from tool nose to the surface to be
machined after rapid traverse ).
It’s recommended that:
a) Drilling, boring and reaming on the processed surface: 1~3mm.
b) Drilling, boring and reaming on raw casting surface: 5~8mm (decided by the
allowance of the surface).
c) Tapping: 5~10mm.Milling: 5~10mm.

Page 64
Instruction manual Document No.: VM50-9302E
5.20.5 Decide the sequence of working procedure
As the many process steps and tools are needed in the machining center, the
reasonable sequence arrangement of the working procedure is important to the
machining accuracy, machining efficiency and quantity of the tool. The sequence of the
working procedure is influenced by the following factors:
1) First do the heavy cutting and roughing, then the machining with little heat
productivity and low accuracy requirement (e.g. drilling a small diameter hole,
tapping, etc.), and finally finishing.
2) Machine the workpiece in the adjacent position first to shorten the idle travel
distance. Consider the tool moving track to reduce the displacement of each
coordinate axis.
It’s recommended to arrange the working procedure according to the following
sequence:
Mill the large end face (rough milling and finish milling is done independently) →
rough boring/semi-finish boring → end mill machining → drilling → tapping → hole
finishing (reaming, boring, finish milling)
5.20.6 Tool selection
The tools used in the machine include universal cutter and universal connecting
toolbar. Select the appropriate tool according to the requirement of machining and the
process chart, determine the tool position in the tool magazine (mark the tool station
number) and map out the tool card (used for tool preparation, adjustment and loading).
Note 1: if the tool length and deviation value can’t be decided at once, adopt the
following two methods:
1) First, set a nominal dimension, and then add tool compensation when
programming. Program with nominal dimension and modify the dimension by tool
compensation value (the difference value of nominal dimension and measured
value).
2) Tool length is not written in the tool card and is zero in the program. Designate a
tool compensation number for each tool and input the measured tool length in the
tool compensation data list after the tool is prepared.
Note 2: Tool length, which is the tool compensation value or the measured length in the
working area after tool is loaded in the spindle, is the axial dimension from cutting edge
to spindle end face.
For the specification and dimension selecting of the toolbar, please refer to the
production sample provided by the toolbar manufacturer.
Special tools are used if the requirement of machining is special. Consider the
interchangeability of each kind of tool when selecting the tool, e.g. end milling with
circular interpolation besides boring can be used to machine the large sized hole.
Page 59 Total 72
Page 65
Instruction manual Document No.: VM50-9302E
Therefore, the user should have a full knowledge of the tool series and performance of
the machine tool and select the tool flexibly.
5.20.7 Cutting data determination
1) Take the cutting data in the Tool Cutting Manual for reference and modify it
according to the on-site experience. Use the data in the cutting database as much
as possible as the development of automatic programming.
2) Modify the data according to the rigidity of the machining—technology system
(tool—workpiece—fixture—machine tool).
3) Modify the data considering tool service life. In medium and small batch production,
try best not to sharpen or replace the tool in a batch to reduce the adjusting time.
To reduce the machining time of heavy load cutting tool, e.g. end mill, rough boring
cutter for deep hole, etc., use larger cutting data to shorten the incorruptibility of the
tool to half or one third.
5.20.8 Tool preparation
Prepare the tool according to the technologic card, the steps are as follows:
1) Select the toolbar and cutter according to the card;
2) Sharpen the cutter or the boring cutter head;
3) Assemble the cutter head, toolbar and end taper and label it with the tool number;
4) Adjust the tool length to the set dimension, measure the tool length and record it in
the tool card. For high precision cutting, e.g. finish reaming, finish boring, etc. do
test cutting according to the selected cutting data and modify the adjusting data
according to the test cutting result.
5.20.9 Compile the “machine tool adjusting list”（it can be included in the process chart）
1) Designate the group number and the concrete tool compensation value when using
tool radius compensation and tool length compensation.
2) The application of on-site selecting switch（e.g. mirroring switch, block skipping
switch, select to stop switch, etc.）
3) The cooling method of the workpiece (which kind of coolant should be used)
4) Precautions of tool number setting, etc.
5.20.10 Coordinate calculation and working track diagram
Do the calculation according to the drawing. Calculate the input data of the CNC
system according to the working path and allowable programming error. The moving
path is simple for the point machining, simple dimension conversion is sufficient for the
programming, which can be further simplified if a reasonable workpiece coordinate
position is selected and incremental method and absolute method are flexibly used.
Numerical calculation is the premise of programming for contour machining and it has a
close relationship with the workpiece contour and interpolating method of the CNC
system. The linear—circular interpolation system simplifies the calculation of the
Page 60 Total 72
Page 66
Instruction manual Document No.: VM50-9302E
workpiece composed by line and arc. Linear or circular approximation is used for the
workpiece composed by other curves. For the complicated tool motion, tool path can be
drawn for the programming.
5.20.11 Compile the program list
For details, see the Programming Manual.
5.20.12 Program input
There are many ways to input the program, among which, using the MDI device is
a simple way, but it spends more time and take up the machine starting time and it’s
error-prone for the long program.
5.20.13 Dry run
To check the program, test run the program after adjusting the machine. The
methods for test run are as follows:
1) Press “MACHINE LOCK” key to check the program.
2) Press “MST LOCK” key to check if the axial movement meets the requirement. To
check the moving track, press “DRY RUN” to shorten the running time.
3) Press “Z-axis Lock” key to check the M, S and T functions.
4) Check if tool compensation and the sign are appropriate. Check if interference
exists in the motion of tool and each component or fixture.
5) The test run time shouldn’t be long. Try best to reduce the malfunction especially
the damage to the machine tool, workpiece, or tool.
5.20.14 Test cutting
When machining, check if the cutting data (can be modified by the OVERRIDE
button), machining sequence and too path are reasonable. Modify the program after the
automatic cycle is over. Check the machining accuracy of the workpiece and take
measures such as finish adjusting tool, modifying tool length and radius compensation,
editing the program, etc. to meet the accuracy requirements.
For the safety concerns, reduce the rapid traverse speed (in control of RAPID
FEEDRATE key).
5.20.15 Does after machining
The modified program after test cutting can be used for workpiece machining in
batches. After machining, store it in the memorizer. The program validated and modified
after production should be saved in the floppy disk or memory card for further use. In
addition, the technology document, program list, etc. should be amended for further
use.
6 Mechanical maintenance
To use the machine correctly and to keep the machine from problems, you need to
maintain the machine periodically. It is very important to keep the machine clean
because the dust, moisture and oil will erode the mechanic and electric parts.

Page 67
Instruction manual Document No.: VM50-9302E
Clear away oil, coolant and dirt in the machine first, cover all outlets with cocks so
that no detergent enters into the machine. Clean the machine with detergent and
remove all the covers and cocks. Check leakage on hydro pipes, loose connection on
connectors or any wear out on connectors and make repair. Clean the machine with
clean cloth without hair. The cleaning job includes cleaning and vacuum de-dust.
Never use compressed air, high pressure water or chemicals to clean the machine.
Please note the following：
6.1 Lubrication System
Lubrication pump and electric controller supply lubrication service. The pressure
controller and low oil feed-back ensure lubrication intervals.
If not used for a long time, force the pump to lubricate the machine manually. If
launch the machine in this case, ball screw will wear dramatically, even burn up. Under
the case that the machine did not work for a long time, lubricating pump should be
manual controlled to supply lubricating oil before conducting.
6.2 Hydraulic System
Medium of hydraulic system：#32 hydro oil (winter), #46 (summer). For a new
machine, change the oil after 3 months. Then every 6 months.
6.3 Pneumatic system
Maintenance period of pneumatic system usually is long. If the element of filter
turned dark in the daily examination, replace the filter element. If find the pressure of
inlet and outlet of filter large , it reveals blocking, replace the filter element.
6.4 Cooling System
6.4.1 Coolant tank
Coolant must always be clean and clear, free of foreign objects. If it is found that
the liquid becomes muddy, change it immediately. Decide coolant according to different
material to cut. Recommend to clean the coolant tank every month.
6.4.2 Oil cooler
The oil cooler has a definite volume. Fill the cooler up at its first use. The
replacement period of coolant is 3 months. The air filter net on the cooler need to be
cleaned once a week.
