Whether single or double tooth cutters, radius cutters or mounted points: vhf manufactures all dental milling cutters on modern six-axis precision grinding centers. For our users, this means short delivery times and a portfolio which is geared to the requirements of our customers. For all questions regarding the best possible processing of your dental materials and the correct use of the milling tool, the specialized dealers trained by vhf are competent contact persons.
Dental milling cutters from vhf are made from a superfine grain carbide mixture from German production. It is characterized by high edge strength and outstanding wear resistance – further improving work piece quality and service life.
Only by choosing a first-class tool will you also achieve first-class results. The tool is the decisive element between your dental milling machine and the material to be machined.
For this purpose, the vhf tool specialists constantly research and develop together with material manufacturers and laboratory users in order to produce the best possible tools.
Our tool specialists have developed optimal cutting-edge geometries for machining the various materials used in dental technology, from wax to cobalt-chrome. The result is a perfect balance between the best possible surface quality of the material to be machined and the longest possible service life of the milling tool. Since we develop and produce the dental milling machines, the CAM software, and the dental milling cutters by ourselves all components do perfectly match together.
The best performance only comes from the original
At vhf, we are keen to offer you the greatest possible variety of materials. During the validation process of new dental materials, all components of the CAM system play a role – that means, machine, software and tool form an optimally coordinated overall solution. This means that our developments and tests always focus also on the milling tool.
This perfect interaction cannot be guaranteed when using tools that do not optimally harmonize with the machine and software, for example those of third-party suppliers. In addition to a reduced tool life, possible tool breakage and reduced milling quality, machine components such as the high-precision spindle bearings can also suffer.
Therefore, we recommend: play it safe and get optimal results as well as a long machine life – thanks to a perfectly balanced system of machine, milling tools and the corresponding machining strategies in vhf’s DENTALCAM software. Long tool life and process reliability are also available at an attractive price-performance ratio: with original dental milling cutters and grinding tools from vhf.
The choice of dental milling or grinding tools plays an important role in dental technology. Because the tool is the decisive link between the dental milling machine and the material to be machined. The vhf tool specialists research and develop together with laboratory users and material manufacturers in order to produce the best possible tool.
The dental milling cutters and grinding tools from vhf have sophisticated innovative geometries for machining all material classes: wax, PMMA, zirconia, composites, titanium, CoCr and glass ceramics. Therefore, when it comes to dental tools, you can rely on the sophisticated products by vhf: for first-class tool life at best quality and at attractive prices.
This special dental radius cutter has a semicircular rounded tip. It is available with cutting-edge diameters of 0.3 mm to 2.0 mm. While the 2.0 mm tool is mainly used for efficient roughing, tools with smaller diameters of 0.3 or 0.6 mm are mainly used for finely finishing or carving out fissures. Due to the especially long undercut of these tools, undercuts in the material can also be reached easily.
Depending on their field of application, the radius cutters have one to four cutting edges: for PMMA and wax there are, for instance, extremely sharp single-tooth cutters available with a very low tendency to clogging. On the other hand, the 2 mm cutters for the abrasive zirconia have three cutting edges and the CoCr cutters even have four, in order to reduce the wear for each cutting edge and to ensure greater process reliability.
Cylindric and torus cutters
The cutting edge of this tool with flat face grinding is extremely sharp and faceted. Thus the milling results are very smooth even at high feed rates and the risk of clogging is very low – even for plastics which tend to build up material.
This tool is available with a cutting-edge diameter of 2.5 mm; it is exclusively used for roughing PMMA and wax. Roughing with such a flat ground cutter reduces the milling time.
The double-edged cutters have a cylindrical face grinding and a cutting diameter of 0.5 mm and 1.2 mm. For milling 90° angles, e.g. in drillings and abutments, double-tooth cutters with flat face grinding and a cutting-edge diameter of 1.2 mm are used.
For machining non-precious alloys on a cobalt-chrome basis and titanium, this tool is available as torus cutter with a small edge radius which protects the cutting edges (only 1.2 mm diameter) – so the tool life will be extended.
For machining glass ceramics and composites, vhf offers torus and radius grinding tools with a diamond grit in different grain sizes. The two torus grinding tools with their fine grain size are mainly used for drillings and abutments. The 2.4 mm radius tools with their coarser grain size are used for roughing whilst the fine-grained radius grinding tools are used for the finishing process.
All tools are characterized by their excellent abrasion and break resistance as well as their extremely long endurance. The diamond grit with its especially good binding to the shank avoids micro-cracks and reduces the sensitivity to thermal impact. In addition, a close screening of the diamond size ensures consistent grain sizes and thus ensures the high dimensional accuracy of the entire tool.
Simply ingenious – ingeniously simple: the vhf tool packaging
The development department of vhf is not only concerned about the perfect cutting edge geometries of your tools, but also about a wonderfully easy handling. Therefore, vhf uses a unique multifunctional tool packaging instead of a conventional standard packaging.
With seven distinct colors, it is clearly visible which tool is applicable for which material class. The base colors of course also match the color-coded tool magazines of the Z4. The respective article number is prominently marked on the protective casing – you don‘t have to take the tool out of the packaging to see which tool you have in your hands.
The individual packages can be coupled, separated and combined as required by means of an innovative sliding mechanism so that you can maintain the best possible overview of the tool contingent, and prevent possible disorder in the workplace caused by individual tools lying around.
In addition, the innovative packaging makes handling not only easier, but also safer. You can conveniently insert and remove the tool stuck in the base into the tool changer of the milling machine without having to touch it with your hand. This reduces the risk of injury and tool breakage.
Our AIRTOOLs make a lot of wind
Completely free of compressed air
The vhf tools do not only influence the excellent machining quality of your workpieces, they even enable a completely new machine generation: A unique innovation of our milling machines E5 and E4 is their freedom from compressed air. They require neither an external compressed air connection nor a built-in compressor. This is made possible by our patent-pending AIRTOOL.
Due to the high speeds of the high-frequency spindle, the turbine blades on the AIRTOOL generate a strong air flow towards the cutting edge of the tool, which keeps the workpiece free of chips and dust. In turn, chips and dust are removed by the connected suction unit. Thus, you can work without a compressed air connection and avoid the corresponding disadvantages. With these two machines of the vhf EASE Class and the AIRTOOLs, you enjoy maximum freedom in choosing the installation site and benefit from significantly lower operating costs.
The specialists for the rough work
The AIRTOOLs are only required for the first milling steps – the roughing process – which produces a particularly large amount of chips. Therefore, they are only available with cutting edge diameters from 2 mm. For the finer finishing process, you still use the standard tools from vhf.
The E5 and the E4 have a separate slot in the tool changer for the AIRTOOL. This means that your restorations are of course also produced fully automatically in the E series.
The color coding also shows for which material the respective AIRTOOL is used.
Dental tools made by experts: by vhf
Lowest tolerances – highest standards
At vhf, compliance with the specified values for the finished tools is regularly checked by a complete measurement with a four-axis measuring machine. The check is carried out with four cameras at a resolution of 0.25 μm. Thanks to this non-contact measurement, we can reliably control the production process. Maximum precision is our top priority – to give you the best machining results.
The finished tools are checked fully automatically by the CNC measuring machine – so no quality defect remains undetected. This ensures an economical production with us and favorable prices with you.
All vhf dental tools are individually laser-marked. In addition, the colored tool packaging allows you to see at a glance which tool you hold in your hands – ideal for quickly equipping your tool changer.
