vhf camfacture AG
vhf camfacture AG
Since 1988, vhf camfacture AG has been a manufacturer of highly precise, fast and robust CNC milling machines. Possible fields of application extend from micromachining to large-volume mould making. Since 2008,
vhf has successfully taken part in the dental market with
its micro-machining systems of the Impression line.
The company has its seat in Ammerbuch which is approximately 30 kilometres southwest of Stuttgart. At the
moment vhf has a staff of more than 180 employees and
has a manufacturing capacity of 1,500 machines per
year.
Distribution via resellers only
vhf milling and grinding machines for dental technology are exclusively
available via OEM partners and the specialised trade. vhf does not directly
sell to end customers – hence we are not competing with you. As vhf reseller you sell the machines in the classic vhf look in your respective sales
area. As OEM partner you sell the machines in your own design and can
distribute them world-wide.
The OEM machines are real masters of disguise: Depending on the purchase quantity, OEM systems either get a different-coloured coating or
even an individual housing construction. Furthermore, in an OEM partnership individual agreements are possible. In any case, confidentiality is
very important for us in such a partnership – each OEM partner may decide
whether their company is indicated on the vhf reseller list or not.
Out of the box
vhf’s milling and grinding machines impress by their
extremely compact construction. Packed in a stable carrier box you deliver the machine to your customer. The necessary accessories are also inside the
box. At the customer’s place you only have to unpack
everything and set it up – no complex installation
or assembly works are necessary. You connect all
cables of the machine and the computer, install the
software and you are ready to start. And in case of
service this process also works the other way round.
vhf camfacture AG
The secret of success...
With more than 25 years of experience in machine-building
and the development of CAM software as well as with the
competence of our partners from the vhf group, we achieve a
high in-house production depth. So the complete electronics originate from the vhf elektronik GmbH and all milling tools
are developed and produced by the vhf tools AG.

The vhf camfacture AG does not only all (technical) design
works, we also manufacture the machine parts for the dental
systems on vhf industrial milling machines. In our final assembly, the machines are built together and tested extensively. It is
this high in-house production depth that makes the sensational
market price of the vhf machines possible – and you as our
partner can realize top profit margins though.
Efficient operation
Due to the Direct-Mill function which is integrated
in the DentalCAM software, you save plenty of time.
While the calculation of the milling paths is still running, the milling process will be started. All further
calculations will proceed in the background.
Additionally, the machining comfort can be considerably increased by different degrees of automatization, for instance with an automatic blank changer
for up to eight blanks. And finally a special highlight:
Due to the rock-solid construction and their high
manufacturing quality, you can process non-precious alloys on CoCr basis with all vhf dental milling
machines!
Service friendliness
As our reseller you are responsible for the technical support
of the end customers. In order to facilitate your work, the machines are service-friendly constructed. Moreover they have
some features which reduce the service effort. One example is
the integrated working chamber sealing air concept, which
protects the mechanics against dust and chippings and thus also
the investment of your customer. So we are able to give a 24
months bring-in warranty even on machines which mill zirconium every day.
Your technicians get comprehensive instruction and training
courses by vhf. Of course we offer you excellent second level
support and help your technicians with words and deeds in the
case that they feel at a loss.

Impression K models
Most obvious is the extremely compact design of the
K models. Upon closer examination, the uncompromisingly rigid construction of the machines leaps to the eye.
So it is ensured that you will achieve first-class results – even
in extremely hard non-precious alloys on cobalt-chrome
basis.
Two extremely affordable dental specialists
High-class drive and measuring units are also essential for
producing perfect objects. Here, vhf relies for instance on
integrated Harmonic Drive® rotary axes. On top of that an
automatic axis measurement and compensation ensure
a consistently high machining precision – and thus top-quality results.
Also the operation is easy: With our model CAM 4-K4 Impression you get an automatic tool changer with six stations
which enables a complete machining of the workpiece –
from the initial rough machining up to the ultimate finishing
– without manual intervention of the operator. However, if
it should for instance not be possible to provide compressed
air, we recommend CAM 4-K3 Impression where the tools
can be exchanged thanks to a convenient quick chucking
device also by hand within seconds.

Fully integrated liquid cooling system
The cooling lubricant is led through eight liquid nozzles
which are arranged at the spindle and cools the whole tool
evenly from the tip to the shank at all machining stages. The
machine bed of massive aluminium cast facilitates highest
stability and a low-vibration operation. Together with
the flexible gaiter at the spindle it furthermore guarantees
that all the liquid will remain solely in the working chamber
of the machine. The removable liquid drawer under the
working chamber also contains a filter mat for separating
grinding particles.
Fixing the three material blocks takes only little time and the
two removable changer stations for four tools each will be
equipped with just a few moves. The material will then be
machined fully automatized and you can spend your time
with other useful things until you remove the finished work.

Impression S Models
CAM 5-S1 Impression and CAM 5-S2 Impression are our most
versatile dental milling machines. They have five simultaneously working axes and are designed for dry machining as
well as for wet machining. The second rotary axis (B axis)
with a rotation range of up to ± 30 degrees enables you to
mill undercuts and so opens up new machining possibilities.

Other highlights are a powerful and highly precise synchronous spindle and an automatic tool changer for 16
tools. In addition to the currently required tools, you can
equip the tool changer with replacement tools right away.
Thus you can continue working without interruption if a tool
is worn out. In order to create a solid basement for the highly
precise five-axis mechanics, the machine bed of the S models
is made of one single massive cast part. Thus these machines gain much stability at minimal exterior dimensions.
Moreover, vibrations are reduced and the mechanics is
optimally protected – also from entering of liquid while wet
machining.

The external wet grinding module has an integrated membrane pump and a refined system for air and liquid treatment. It dries the extracted air and filters the cooling liquid from grinding particles. The regularly used dry vacuum
cleaner simply has to be connected to the wet grinding
module instead of to the machine.

However, you do not need a new machine for wet grinding
– just an external module and appropriate holders for the
glass ceramics blocks (see page 15) for the Impression S
models. The wet grinding module which regulates the liquid circulation is connected with two hoses for supply and
drainage with the machine. From three liquid nozzles that
are already integrated into the spindle block, cooling liquid
will be directly targeted to the tip of the tool. Thus an
efficient cooling is ensured during the whole grinding process.

For wet grinding vhf’s range of tools includes a torus grinding tool with coarser grain size for roughing, as well as
a fine-grained radius grinding tool for finishing the surface afterwards. These tools are also available as starter set.
Please see page 19 for more information about the grinding tools.
liquid circuit
The suction mixture of air and liquid is divided
into two circuits. Due to the intelligent labyrinth air
guiding system, a large part of the humidity will be
separated from the extracted air. So the wet grinding option can be operated with a dry vacuum
cleaner, there is no additional device required.

Software
DentalCAM version 5
This CAM software for the dental technology is especially
adapted to the CNC milling machines of the Impression line.
Its operation does not demand any previous knowledge due
to the clearly structured user guidance. At first, the software lets you choose the required blank of different materials. Then you can import your earlier modelled CAD data via
the standardized STL format into this open program. The
software supports you with comfortable placement aids
in an optimal utilisation of space on the blank.
There are just a few mouse clicks necessary until you can
mill your bridgeworks. You place the bars which connect
the framework to the blank. If necessary, you can also place
drops for the sintering process. It is also possible to machine a blank in several stages; the teeth which have already been milled in a previous pass will be displayed in a
different colour and establish a protected area.
Finally, the milling paths of the different tools will be calculated fully automatized and highly optimised. Due
to the four or five axis path calculation, milling undercuts
is no problem any longer. While the milling paths of other
objects or the finishing processes are still being calculated,
the machine already starts – thanks to the Direct-Mill function – the roughing process. All relevant data concerning
blanks, fixing devices and tools have been stored in the CAM
software – you do not have to bother about such technical
details any more. The user workflow is speed-optimised
to such an extent that the whole preparation for a regular
crown takes less than one minute from switching on the machine up to the start of the machining process.
Thanks to new machining strategies, it is now possible to
mill non-precious alloys on cobalt-chrome basis with all
current vhf dental milling machines.

suitable for 4 axis and 5 axis simultaneous
machining; thus maximum accessibility of
undercuts
comfortable choice of materials for new
blanks, respectively selection of a suitable
used blank via the material archive with
search and filter functions and preview images
operation via self-explaining icons and keyboard shortcuts for the most common functions; rotation of objects via scroll wheel
the automatic blank height optimization can
rotate the object within the blank in such a
way that the blank height will be optimally
utilised by an appropriate twist of the rotary
axis – so you can use flatter blanks
sintering bars and sintering drops can be attached to your objects
automatic recognition of prepline, divergencies of fits, drillings and undercuts
extensive auxiliary functions for placing and
editing bars; additionally the bars can be either reduced or fully removed – this means a
considerable reduction of reworking
machining strategies are adapted to any
kind of object (crowns/bridges, abutments,
models, temporary dentures etc.); special
strategies for prepline and cavity; the kind
of object and its machining quality and the
machining status (to be machined now, already machined, to be machined later) can
be freely combined
fully anatomic objects or inlays will be machined with an extra small tool where necessary
usage of cylindrical tools for drillings
grinding strategies for glass ceramics can be
added via software extension
a residual material detection makes it possible that an object will only be machined
at such points with a smaller tool where it
is necessary
intelligent tool changer: usage of replacement tools if main tool is worn out or broken
is possible
different functions for automatic and manual
determination of the milling order
the Direct-Mill function enables an immediate start of the milling process while the
milling paths of other objects or the finishing
processes are still being calculated
the blanks can be automatically marked so
that you can exactly re-chuck them
automatic buffering of current milling output – very useful for instance in case of an
interrupted machining process due to power
failure
output of a manufacturing protocol in
spread sheet form for a better assignment of
the milled objects
decoupling of the CAM and CNC modules
for the independent creation of new milling
jobs

After five simple steps your object is ready for milling:
1. Choose the object in the file browser.
2. Preview of the object and possibility to view the file from all sides using the STL viewer.
3. If necessary, the vertical alignment of the object in the blank can be adjusted here.
4. Determine the machining strategies by choosing the type of object and the quality, by (de-)activating the blank height optimization
as well as the possibility to disable the automatic search for divergent insertion angles and drillings in the objects.
5. Finally check the objects in the import list and import the complete list to the nesting window. There you just need to place bars and,
if necessary, drops and the milling output can be started.

vhf dental tools
Our tool experts have developed sophisticated cutting edge geometries for machining the different dental materials from
wax to cobalt-chrome. Thus the optimum
balance between a best possible surface
quality of the machined material and a
preferably long endurance of the tool
is ensured. All dental milling cutters are
manufactured by vhf on modern six- and
seven axis precision grinding centres.
Dental milling cutters from vhf consist of a
super finest grain carbide mixture of German origin. It is characterized by its high
edge strength with high resistance to
wear and ductility at the same time. This
additionally improves the workpiece quality and the endurance.

available with variously optimized cutting edge
geometries and with accordingly adapted coatings if this is reasonable for the respective material: wax and plastics (PMMA), zirconium oxide,
composites, LavaTM-Ultimate materials as well as
non-precious alloys on cobalt-chrome basis. In
addition we offer grinding tools for machining
glass ceramics. The tools have different-coloured stop rings, so that you can easily distinguish them.

Radius cutters
This special dental radius cutter has a semi-circular rounded tip. It is available
with cutting edge diameters of 0.6 mm, 1.0 mm and 2.0 mm. As the 2.0 mm
tool is mainly used for efficiently roughing, tools with the small diameter of 0.6
mm are mainly used for finely finishing or carving out fissures. Due to the especially long free grinding of these tools, also undercuts can be reached easily.
The tools for plastics/wax and for Lava™-Ultimate are uncoated, for zirconium oxide they are uncoated and coated, the tools for composites and CoCr are always
coated.
Cylindric double tooth cutters
A double tooth cutter with flat face grinding and a cutting edge diameter of
1.2 mm. It is used when 90° angles have to be milled, e. g. in drillings and abutments.
For machining non-precious alloys on cobalt-chrome basis, this tool is available
as torus cutter with a small edge radius which protects the cutting edges. So a
higher endurance is guaranteed.
The tools for plastics/wax and for Lava™-Ultimate are uncoated, for zirconium oxide they are uncoated and coated, the tools for composites and CoCr are always
coated.
Cylindric single tooth cutter
The cutting edge of this cutter with flat face grinding is extremely sharp and
faceted. Thus the milled edges are very smooth even at high feed rates and the
risk of clogging is very low – even for plastics which tend to smear.
This tool is available with a cutting edge diameter of 2.5 mm; it is exclusively used
for roughing PMMA and wax. Roughing with a flat ground cutter reduces the
milling time.
Grinding tools for glass ceramics
vhf offers three tools for grinding glass ceramics: a torus grinding tool with
coarser grain size for roughing and two fine-grained radius grinding tools for
the later finishing process.
All tools distinguish themselves by a good abrasion and break resistance, and
their endurance is very long. A diamond grit with especially good binding to the
shank avoids microcracks and reduces the sensitivity for thermal impact.
