TW-Mill
The modular joinery machine

modularity-driven flexibility
TW-Mill - The joinery machine
System advantages
• very robust design
• vast diversity of variants
• in mobile or fixed version
• individual number and positions
of units
• individual quantity of tool sites
• individual rail lengths
• individual passaging width
The option for individual features leaves nothing to be desired.
The dimensions of the plant can be specified at the coustomer`s need - depending
on the situation in the factory and on the planned product-range.
The basic version of the TW-Mill can be delivered in its mobile variant - the portal
then moves on rails over the workpiece. For the fixed TW-Mill, the workpiece is
automatically infed on portal trolleys, moved through below the portal and
discharged following processing.
The quantity of units as well as the tool sites is freely eligible.
The high-performance spindle, tool changer and further components were
composed to an optimal costom-made solution.
vielfältig einsetzbar
In the Technowood TW-Mill operating
centre, any items like hard wood
plates, solid wood plates, laminated
timber, board stacks, sandwich plates
and other panels can be processed rationally
and accurately to the millimetre.
Furthermore, the plant is designed for
cutting off one or several single rods.
Large elements like box beam, roof,
ceiling and wall elements can be completely
handled.
modular erstellbar
The TW-Mill impresses by its modular
and high-quality design. It is possible
to freely determine the length of
the facility, the passaging width, the
opening height, the configuration and
the number of units as well as many
features more.
Depending on the customer‘s wish, the
cut-off portal TW-Mill can be put on
rails as mobile version. Then, the portal
moves above the workpiece during
processing, while the workpiece is positioned
on the processing table.
For the stationary version of TW-Mill,
the portal remains fixed, the portal trolley
executing the axle movement in X
direction. These so called „TW-Carriers“
lead the workpieces through under the
portal with its milling and spindle units.
Of particular interest is the option for
automatic infeed and discharge.
qualitativ hochwertig
Due to its stable, closed construction
the TW-Mill is very precise in processing
and achieves high natural resonant
frequencies. The units can be moved
away from the table area in their y
axle. This enables comprehensive
processing inclusive deep horizontal
borings. The basic design of the portal
holds a complete 5-axles unit. This
24kW, water-cooled high-performance
spindle automatically obtains the
required tools from the tool changer.
Tool speeds of max. 16000 rpm can be
freely programmed for every tool.
leistungsstark ausgelegt
Optionally, a high-torque, 5-axles saw
unit can be used, for example. This
unit can host a saw blade with a maximum
diameter of 1000 mm. It is able
to tilt it to the horizontal. In addition to
all conceivable cuts, this saw is capable
of cutting jags, skew notches, grooves,
slots, etc. The design spindle and saw
mounting is low-collision - both units
are positioned below the Z-arm.
effizient arbeitend
Tool changeover times are very short,
as the spindle is able to get a new tool
from the stack while the saw is still
working. All axles are equipped with
positive measuring systems, reference
runs thus becoming unnecessary.
Individual positioning, number and design of
the spindles
Dimension of the equipment according to
the customer`s desire
Basic versions are mobile or stationary
portals

The mobile TW-Mill
Variant with mobile portal
Advantages of the
mobile version
• high flexibility due to the large,
open processing surface
• option for creating the
processing table in accordance
with own requirements
• length of the plant corresponds
to the max. workpiece length
• deeper investment
The mobile TW-Mill resembles a very flexible version of the device. The workpiece
is planted on a processing table. The portal then moves on guiding rails over this
workpiece for processing. The customer is free to determine the length of the rails.
The operating centre holds an accompanying switching cabinet and compressors.
Only power supply is to be fed additionally. There is no need for carrying along
subtle feeder components. The portal can be equipped with either a moveable
suction system or connections for an external suction. For the external connection
a moveable closing element - a so called „toad“ running in a „toad channel“ - can
be offered optionally.
The machine table can be designed differently as required: as closed table, as
holms table, with scratching ground, with element transport system, with vacuum
Bucky table, etc. Discharge of the residual timber can be done optionally below the
table via a conveyor system.
TW-Control
The powerful multiple axles control
A standard PC with Windows operating system is able to run the machine control.
A real-time system monitors the maximum of 64 NC axles concerning their absolute
synchronicity. The control interprets the worldwide standardized ISO code in
accordance with DIN 660250. The flexibility of this control almost knows no limits
with its additional functions and an integrated high-level language.
Basic configuration standardly comprises automatic tool correction and practiceoriented
tool and neutral point data management.
We supply the control including the dynamic collision monitoring unit
TW-DCD, which offers a comprehensive simulation for machine and production
facilities. In case collision-monitored parts come below a certain spacing, a warning
or error message is triggered stopping the travel lengths. Of course, TW-DCD
shows the operator those parts of the plant which are heading for a collision.

The statical TW-Mill
Variant with fixed portal and moveable portal trolley
Benefits of the portal
trolley version
• high efficiency due to automatic
infeed and discharge
• handling of all six sides of the
component
• linkup to further features possible
(e.g. engine lathe)
• all stops can be retracted
• range of up to 2000mm
(extensible)
For the stationary version of TW-Mill, the portal remains fixed, the portal trolley
executing the axle movement in X-direction. These so called „TW-Carriers“ lead the
workpieces through under the portal with its milling and spindle units.
All TW-Carriers are identical and designed as full-value servo axle, allowing for
exact positioning. To prevent massive friction when repositioning the trolleys the
supporting area can be lowered. The stop as well as the tensioners of the TW-Carrier
can be retracted as well. This results in a free surface which enables flexible
infeed and discharge backwards and forwards.
Of particular interest is the option for automatic infeed and discharge. Chain cross
conveyors implement infeed of the components. The infeed can be used as driven
discharge as well. Otherwise the processed components are discharged by gravity
via slanted roller rail with stop at its end.
