the equipment to measure the tool parameters viz., diameter and length & update them in the
equipment automatically.
The tool measurement system should be able to measure the sizes from dia 5mmX40mm long

3.6 Mist Extractor and Oil Mist Separator
The equipment should be provided with a mist extractor to extract the coolant mist from the
working area. Provision should be there to operate this mist extractor in manual mode as well
as in auto mode.
The coolant mist so extracted should be passed through an oil mist separator to separate out
the moisture from the mist & to let only the air out. The moisture which is separated should
get collected so that it can be drained off periodically.
Vendor should provide all the technical details of mist extractor and oil mist separator
offered.
3.7: Central lubrication system:
The equipment should have a centralized lubrication system for automatic lubrication of
guide ways and lead screws of all axes at regular intervals. Provision for monitoring the
lubricant level should be there.
Vendor should provide the technical details of the lubrication system being offered and the
details of the lubricant to be used.
3.8 Coolant circulation system for Tool & Job Cooling:
-
Equipment should have provision for coolant flow through the spindle center as well
as a multi jet unit surrounding the milling head. It should be possible to switch from
coolant to air in the multi jet unit. The flow and pressure parameters for coolant flow
through the spindle and for external coolant (multi jet unit) should be displayed in
equipment
-
Most of the time, ZERODUR and optical glass will be milled on this equipment using
diamond tools. Material is removed in the form of fine powder and gets carried away
with the coolant. Hence, there should be a system, to filter the coolant at different
levels (coarse and fine) and to separate out the powder from coolant before it enters
the coolant tank.
-
It is desirable to have following type of coolant circulation system in the equipment:
The coolant being returned from the equipment consists of fine glass powder
suspended in it. This should be collected in an intermediate settling tank from where it
should be pumped to the main coolant tank as and when the level in the intermediate
tank reaches a set value. This coolant should pass through a centrifuge which should
have a conical shaped rotor rotating at high RPM. Coolant while passing over the
rotor undergoes directional change and due to centrifugal forces, the glass powder
remains in the centrifuge and coolant alone goes out. This coolant should be further
filtered using a cartridge type filter to less than 20 micron level and it should be
pumped back to equipment. The temperature of coolant in the main tank should
always be maintained, using a chiller unit mounted on the coolant tank.
1
-
Vendor should note that inspite of filtration at different levels; coolant still consists of
fine glass powder which can erode the equipment parts especially near the spindle
through coolant passages. Hence, the through coolant system in the spindle should be
designed accordingly to avoid erosion of spindle parts. The spindle should have a very
good sealing mechanism to avoid entering of coolant into the spindle bearing area.
-
The coolant being pumped from coolant tank to equipment should be filtered to less
than 20 microns filtration level. There should be a separate pump and motor for
external coolant (coolant jets around the milling head) and for coolant through the tool
(through the spindle center)
-
The flow rate and pressure of the through coolant as well as external coolant should
be monitored & displayed on operator panel.
-
Condition of the filters at various stages should be monitored and there should be an
alarm when the soiling of filter exceeds allowable value.
-
The coolant tank should have a capacity of at least 500 Lts
-
The material of tank and its paint should be compatible for water soluble cutting
fluids.
Vendor should provide all the technical details of the coolant recirculation and conditioning
system offered.
3.9 Cooling system for cooling spindle motor and axis lead screws:
- The equipment should be equipped with a chiller unit to cool the spindle motor and axes
lead screws to avoid excessive heating.
-The temperature of spindle motor and axes motors should be monitored and displayed on the
operator panel.
Vendor should specify the technical details of cooling system offered.
3.10 Hand Held Unit:
A mini hand held unit to move the linear axes and rotary axes in Jog mode should be supplied
by the vendor. It should be possible to move each axis in steps of 0.001, 0.01, 0.1, 1.0mm
(selectively) and also into continuous mode. There should be an emergency push button
provided on the hand held unit.
3.11 Protection for operating personnel and equipment components:
The working area of the equipment (NC rotary table, X,Y,Z axes, Spindle and milling head)
should be fully enclosed in a cabin including the roof portion. Such a cabin should have
sliding doors and large safety glass windows for observing the working area.
1
It should be possible to load the Jobs of size upto Dia 1500mm X 500mm thick using the
crane directly onto the Rotary table.
Safety interlocks should be provided to restrict the working of equipment in auto mode &
coolant circulation while the cabin doors are open.
The guide-ways of the axes should be covered suitably to avoid the coolant from entering into
the guide-ways.
3.12: Spindle Monitoring:
There should be a provision for monitoring the condition of the spindle by sensing the
vibration at spindle and in the case of vibration exceeding the set limits, equipment should be
stopped.
There should be a provision to monitor the condition of spindle bearing.
There should be a provision to monitor the torque on the spindle and in case of the torque
exceeding the set limits, milling process should be stopped.
3.13: 3D data model of equipment configuration
Vendor should supply the 3D data model of the equipment configuration. The data model
should mainly include equipment bed, milling head, working table, linear and rotary axes and
cabin. This data model should be supplied in a format that is compatible with CAM softwares
such as DELCAM. It will be integrated with CAM software and will be used for off-line
simulation of 5 axis milling programs in CAM software, before actual execution in the
equipment.
3.14 Automatic Tool Changer (as an optional item)
