Diamond Tools

Diamond is even much harder than carbide. Diamond tools – at vhf these tools consist of a carbide shank with diamond attachment – provide you with a multiple of the endurance. A further great advantage of diamond tools is the fact, that they are suitable for dry processing and furthermore, regrindable for several times.

For processing wood, plastic and non-ferrous metals we recommend polycrystalline diamond (PCD) as cutting material. CVD diamond thick film plates are used for milling very hard materials such as GRP-/CFRP materials or hard non-ferrous metals. Tools with monocrystalline diamonds (MCD) as well as tools with polycrystalline diamonds (PCD) are available for polishing milled edges.

PCD single tooth cutters

If the cutting edge is made of diamond instead of carbide, you will achieve a significantly improved surface quality and endurance – without coolant.

PCD double tooth cutters

The second cutting edge again extends the endurance and enables a slightly improved smoothness. This milling cutter is ideal for processing harder materials.

MCD polishing cutters

You can produce polished acrylic letters or logos of any shape directly on your milling system. Separate polishing machines become dispensable.

MCD polishing gravers

This tool with its attached diamond polishes engravings on sophisticated acrylic signboards etc. to a high gloss. It is available with a top angle of 60° and 90°.

PCD polishing cutters

For polishing acrylic letters or logos of any shape - with extra long cutting edge for polished edges without disturbing steps.

PCD polishing gravers

For shining engravings; due to an extra long cutting edge suitable for very deep engravings - with 60 and 90 degrees top angle.

CVD cutters

Tool with CVD cutting plates which distinguish themselves by an especially great hardness and endurance; ideal for abrasive materials.

Diamond tools from vhf

Despite their higher cost price, diamond tools are the more economic alternative for many processing tasks – last but not least due to the possibility that they can be regrind for several times. vhf uses three sorts of carbide tools with diamond attachment.

Monocrystalline diamonds

Our monocrystalline diamonds consist of pure carbon and are extremely resistant to wear. Although they have been produced synthetically, they have the same characteristics as natural diamonds. This ultra-hard material ensures glassy polishing edges. MCD tools are excellent for polishing acrylic glass to a high gloss.

Polycrystalline diamonds

Polycrystalline diamonds will be sintered from numerous single crystals at high temperatures and pressures to a solid plate. This production process is comparable to that of carbide. Depending on the grade, they are suitable for milling and polishing tasks.
The PCD polishing plates have a very fine grain size and will be finished by grinding in a separate step after laser cutting respectively eroding. Thus, there are only slight differences in polishing quality compared with the results of MCD tools. However, in most cases they are more than compensated by the effect of the longer cutting edges.

CVD thick film plates

CVD thick film plates are built up in thin layers by Chemical Vapour Deposition (CVD). Afterwards they are cut into shape by a laser beam. The result is a very homogeneous diamond structure and an extremely smooth cutting edge for highest surface qualities. Compared with the already very good results of PCD tools, the CVD tools distinguish themselves by an even greater hardness and resistance to wear which can lead to an even longer endurance.
