Count on carbide tools

Due to its extraordinary features, tools made of carbide metal are far superior to those made of high speed steel (HSS). For high speed cutting, HSS tools can no longer be used. All tools from vhf are carbide tools – either completely or partly. Most of the tools are solid carbide tools, the diamond tools consist of a carbide shank with an attached diamond and the router bits have carbide cutting edges.

Sintered from finest powders under high pressure

Sintered from finest powders under high pressure

Carbide metal is a sintered material and consists mainly of the hard material tungsten carbide (WC). For a targeted optimization small amounts of other carbide phases may additionally be used. Mainly these are titanium carbides (TiC), tantalum carbides (TaC), niobium carbides (NbC) or chromium carbides (CrC). The second main component is the binder phase which mainly consists of cobalt (Co) and may partly be complemented by nickel (Ni), iron (Fe) and nickel chromium (NiCr).

Hardness, resistance to wear and ductility of the carbide are significantly influenced by the combination of its ingredients and the grain size of the hard material. An increasing proportion of tungsten carbide leads to increased hardness and ductility and higher resistance to wear. Milling tools mostly have a tungsten carbide proportion of 90 %. Relevant grain sizes range from less than 0.2 microns (nano) to over 1.3 microns (fine/medium grains) – smaller grain sizes result in a greater hardness and bending strength . The material becomes more resistant to wear. If the proportion of the binder phase increases (especially Co of about 10 %), the bending strength, tensile strength and impact strength can be improved. The material becomes „tougher“.

For example, many vhf single tooth cutters are manufactured from the carbide type DK460UF, which consists of 90 % tungsten carbide and 10 % cobalt; the average tungsten carbide grain size in this case is 0.5 microns. Thus it offers a balanced mix of wear resistance and toughness.

Hard coatings for longer tool life

Nowadays, carbide milling tools are often additionally coated with hard material. By the proper choice of the coating, the tool endurance will be considerably extended. The range of possible coating alternatives is wide.

CC AluSpeed®

CC AluSpeed®

This coating has been especially designed for high performance milling of aluminium (alloys). Due to its low affinity to aluminium AluSpeed® effectively prevents the formation of built-up edges. Extremely smooth surfaces reduce the friction at the cutting face and facilitate the chip flow. Due to its great hardness also an excellent protection against wear is ensured.

CCDia® MultiSpeed Thin

The high-end coating MultiSpeed combines an optimised coating adhesion with a smooth surface and an extremely high wear volume. This multilayer coating also has crack-stopping properties which lead to additional endurance. As it is a relatively thin diamond coating, the cutting edges will nearly not be rounded off. Thus it is especially suitable for all non-ferrous metals (also in combination with fibre materials) and wood.

Please note: Diamond is an insulator, i. e. there is no measuring by means of electric contact possible.

CCDia® FiberSpeed

CCDia® FiberSpeed

FiberSpeed is a diamond coating which is optimised for the special requirements of machining fibre reinforced plastics (CRP, GRP) and has ideal adhesive properties. The high surface quality counteracts any possible adhesive tendencies of the machined materials. Due to its very thick multilayer composition with 9.0 μm it can be used extremely long.

  • Coating colour: dark grey
  • vhf tools: diamond-toothed PCB outline cutters, spiral-toothed PCB outline cutters

Please note: Diamond is an insulator, i. e. there is no measuring by means of electric contact possible.

The coatings also differ in their layer thickness which range from less than 2 microns to over 12 microns. The thinner the coating layer, the lower is the cutting edge rounding and the sharper remains the tool. This is especially important for single tooth cutters. But with decreasing coating thickness its protective effect also decreases. Thus the coating thickness is defined individually for each tool type by vhf.

Different substrates and coating solutions are therefore also used on carbide tools manufactured by vhf – always with the goal of creating the best possible tool with greatest user benefit. In the selection of our technology partners we make it a priority to ensure that these are renowned companies with high levels of quality awareness. Long-term partnerships are taken for granted and help us to participate quickly in new market developments or to influence these or even to push them forward.

Due to the rising demand for carbide and the, among others, significant rise in the prices for base materials, carbide is to a high proportion recycled. The scrap – old carbide tools and cutting inserts – or grinding sludge from the production, are completely prepared and will be sintered again or can be used for the alloying of steels.
