Original vhf tools are manufactured by a particularly quality-conscious supplier: ourselves. We develop and produce to the highest standards carbide and diamond tools for milling, cutting, thread milling, engraving, chamfering and more.
On this page, we introduce our versatile CNC tools and provide valuable tips on how to use them so that you can reliably process almost any material.
vhf offers an impressive range of milling cutters: these tools made of carbide have one to four cutting edges and are available in more than 600 variants.
vhf offers a wide range of gravers and engraving cutters for different materials. With top angles from 15 to 92 degrees and engraving widths from 0.1 mm to 1.0 mm, you have full flexibility with the original vhf engraving tools.
These tools don’t give burrs a chance: smoothen the edges of your workpieces with deburring tools from vhf.
Router bits are ideal for woodworking. However, due to their carbide cutting edges, they are also excellent for machining other materials such as plastics.
For thread sizes from M 1 to M 16, vhf offers different types of thread milling cutters. There are tools available that cut threads in pre-drilled holes as well as combined circular thread cutters with drill, which combine the complete process of thread production into one working cycle.
Our CNC drills are available with cutting edge diameters from 0.2 mm to 6.5 mm in various designs.
As various materials such as foam rubber, cardboard or some composite materials can be optimally cut into the desired shape with a lance, vhf offers in addition to its cutting heads a selection of appropriate carbide lances.
Diamonds are much harder than carbide. With diamond tools – at vhf these tools consist of a carbide shank with an attached diamond – you can benefit from a multiple of the tool life. Furthermore, a higher wear resistance characterizes our diamond tools.
At vhf, machine, software, and tools form an optimally coordinated package. Thus, also the milling tool is always in the focus of our developments and tests. With original vhf CNC tools, you will maintain this perfect interaction of all components – for optimum results and a long machine life.
Because at vhf we ensure controlled quality: the inspection of finished tools by a CNC measuring machine guarantees accuracy for highest demands. The most possible precision is our absolute priority – so that you will achieve best machining results.
Our tool specialists develop sophisticated cutting geometries to precisely design the tools for their use in a wide range of different materials with the optimal machining strategy.
vhf manufactures its CNC tools on modern six-axis precision grinding centers. These guarantee optimal conditions for the production of complex milling tools of highest quality. For our tools, we exclusively use high-quality ultrafine grain or superfine grain carbide grades from German production. This means that you always get a carbide tool of absolute top-quality for your tasks that perfectly meets your requirements.
If you order your CNC tools by 12 noon, they are usually shipped the same day. In addition, our online shop stocks all the necessary consumables and important accessories for customers who already own a vhf milling machine. For all orders placed via the vhf shop, the delivery within Germany, the EU and Switzerland is free of shipping costs, for all other regions attractive shipping rates apply.
So you can find the right CNC tool for every application. That not only gives you higher feed rates and greater durability, but also improves the finished surface of your workpieces.
Their exceptional hardness, durability and rigidity make carbide tools vastly superior to those made of high-speed steel (HSS). Carbide tools from vhf are therefore ideally suited for high-speed cutting.
Diamond tools – at vhf these are CNC tools with a carbide shank and a diamond tip – are several times more durable and so the more cost-effective alternative for many machining tasks. In addition to their exceptional hardness, another major advantage of diamond tools is that they are suitable for dry machining and can be reground several times.
Increase the working life of your CNC tools significantly by choosing a coated vhf carbide tool. vhf offers you a wide range of alternative coatings to ensure you always get the best result for every application.
Always choose a CNC tool that is suitable for your material. Please refer to the detailed descriptions of the tools and their fields of application in the vhf catalog and in our online shop.
You may also use the possibility of a personal advice on tools by phone or email. In order to be able to give you the most suitable recommendation, please give us some information about your application:
In order to be able to set optimum values for lowering speed, dipping depth, feed rate and rotational speed, a number of factors are important. It is not always possible to provide generally valid information on the tool parameters.
Take advantage of our personal parameter advisory service – by phone or email. Please provide us with the following information about your application and machine:
Our recommendations are empirical values, which should serve you as an aid and introduction. In any case, please observe all safety and protective regulations of your machine.
The dipping depth of the CNC tool depends on the power of your spindle and must be in relation to the feed rate and speed. When milling deeper grooves, it is recommended to choose lower removal rates at higher feed rates. The following guide values apply to the ratio of milling depth to cutting edge diameter:
Please pay particular attention to the load display of the spindle controller, especially for large tool diameters in difficult-to-machine materials such as stainless steel. Therefore, approach the specified dipping depth only step by step.
The choice of milling direction depends mainly on the design of the milling machine (portal milling machine or machining center). The material, the milling tool and the parameters also play a role. When milling a groove, there is always a leading and a trailing edge.
Examine your workpiece edge and the edge of the remnant. If necessary, the direction must be reversed.
When machining non-ferrous metals as well as steels, continuous cooling of the milling cutter during machining is essential to ensure both the durability of the CNC tool and the quality of the workpiece edge. For some plastics, cooling by compressed air can already help.
If cooling is not possible, the feed rate of the milling tool should not be set too low. The heat dissipation takes place here through the chip. Otherwise, there is the danger of excessive heat development in the material.
Problem | Possible solution |
---|---|
Melting of the material, sticking of the chips, heat problem | – Increase the feed rate – Decrease rotational speed – Reduce material removal if necessary |
Clogging of the tool’s flute | – Reduce chip volume through reduced material removal – Check suction – Use a tool with larger flute |
Burr formation on the workpiece edge | – Increase the feed rate – Decrease rotational speed – Increase cooling – Replace blunt tool |
Tool breaks off | – Adjust parameters – Reduce removal rate – Check collet chuck/replace if necessary – Check clamping and machine for vibrations |
Poor edge quality due to chatter marks | – Reduce the feed rate – Increase the rotational speed – Check collet chuck/replace if necessary – Check clamping and machine for vibrations |
Unusually high tool wear | – Check material composition – Check collet chuck/replace if necessary – Adjust parameters – Check machine |
