How often can a PCD tool be sharpened?2021-11-02T09:23:20+00:00

The sharpening of a diamond tool is a very delicate process and must be carried out by qualified centres; to ensure maximum tool safety, it is necessary that the tip seat remains intact as otherwise the tip might break away from the tool during use.
Every sharpening procedure erodes about 0.2 – 0.3mm from a single diamond tip. That’s why, for example, cheap tools with a thin tip can’t be sharpened more than 2 or 3 times, while thicker tips can be sharpened about 8/10 times.

How long does it take to sharpen a diamond tool?2021-11-02T09:22:45+00:00

There’s no standard time that applies to all tools. It’s important to bear in mind:
-the type of tool
-the type of sharpening needed: finishing or precision finishing
-the technology to be applied to that particular tool
-how much diamond needs to be removed to give the cutting edge a new lease of life

What materials can I process with a PCD router bit or boring bit?2021-11-02T09:22:03+00:00

Thanks to its innate characteristics, the diamond can process hard, wood-based, plastic or non-ferrous materials.
It’s unlikely that the same tool can be used on materials of different types: the specific sharpening technology used makes it suitable for one material rather than another.

What materials can I process with a carbide tool?2021-11-02T09:21:24+00:00

Tungsten carbide can be used to process many different types of material:
– all wood-based materials
– all plastic materials
– ferrous and non-ferrous materials

Can the maximum feed speed of a Cutter for CNC indicated in the catalogue be taken as a reference for every type of material?2021-11-02T09:20:47+00:00

No. The parameters indicated in the catalogue refer to the minimum and maximum range allowed for that type of tool, and they vary according to the type of machining and the material.

Can Wirutex’s PCD Router Bits be used for machining plastic or very hard materials in general?2021-11-02T09:20:15+00:00

Definitely, but the performance changes depending on the material being processed.
If you want information on how to use Wirutex products in the best possible way, contact the technical-commercial office.

Nesting operation: how many mm should a router bit descend under the lower panel surface, for optimum yield?2021-11-02T09:19:02+00:00

Wirutex usually recommends 0.2 – 0.3mm.

What’s the advantage of a heavy metal body over a steel one?2021-11-02T09:18:13+00:00

The heavy metal is obtained by sintering, so it guarantees outstanding rigidity and high stress resistance.

What is an Aerotech®? What are the advantages?2021-11-02T09:17:24+00:00

Aerotech® is an extraction turbine that captures machining dust and chips during nesting and routing operations. 
This system protects operators from inhaling dust, limits energy wastage thanks to the reduced use of compressed air, cuts machine downtime, extends the lifespan of the tool, and prevents dust from impeding the proper functioning of the machine.

What are the differences between a ThermoGrip and a Hydro-Grip chuck?2021-11-02T09:16:30+00:00

The ThermoGrip chuck is a thermal shrink clamping system that guarantees stability and rigidity.
The Hydro-Grip chuck has a hydraulic clamping system that allows quick tool changes.

Which chuck for CNC offers the best hold?2021-11-02T09:15:36+00:00

The best hold is guaranteed by thermal shrink technology. It uses an interference fit, so the clamping force is directly proportional to the size of the s hank of the Cutter and that of the hole on the chuck itself.
For more information, visit the page dedicated to chucks

Which chuck for CNC offers the best performance?2021-11-02T09:14:31+00:00

It depends on the type of application it’s used for: thermal shrinking offers optimum rigidity, whereas the Hydro system combines good rigidity with the ability to minimise run-out due to the shaft/bore coupling.

How do I couple a cutter with ThermoGrip?2021-11-02T09:13:34+00:00

Coupling is a very simple process that calls for a specific machine.

Boring bits catalogue: what are the advantages of a W-Plus bit compared with a standard bit?2021-11-02T09:12:35+00:00

The sharpening technology used on “W-Plus” bits produces a high-performance tool that guarantees a longer working life and an extremely high number of bores.

What’s the lifespan of a tool in terms of linear metres?2021-11-02T09:11:53+00:00

There are no standard data that apply to all tools. The duration is affected by the type of material, the feed rate, the machine condition, the shifts worked and the chuck used.

What’s the meaning of Z=1+1, Z=2, etc.?2021-11-02T09:10:15+00:00

It indicates the number of tips that work on the profile section being processed.

Machining parameters, feed rate – optimum RPM of each tool2021-11-02T09:09:25+00:00

In order to be able to recommend the optimal machining parameters for each tool, the user must provide specific data such as the panel material/thickness/coating, the type of processing required and the machine used.

What’s the difference between braze-welded PCD pre-milling cutters and cutters with PCD inserts?2021-11-02T09:08:41+00:00

The main difference lies in the accuracy: braze welding guarantees constant precision over time and can’t be altered by any external factors, unlike mechanical fixing which is subject to changes due to human intervention, bad settings, or machine malfunctioning.

Another difference is the level of safety guaranteed: the braze-welded tool has to pass overspeed tests with a component equal to 2x, while the mechanical fixing tests stop at 1.5x.

Are there any particular factors to consider when choosing a blade for machining advanced or specific materials (such as GRP – glass-reinforced plastic)?2021-11-02T09:08:04+00:00

The only feature that distinguishes the blades for processing these materials is the geometry of the tooth, but other characteristics may also vary depending on the specific application.

In this case too, we recommend getting in touch directly with the technical-commercial office to define the right blade.

When it comes to PCD saw blades, what does H=4 or H=6 mean?2021-11-02T09:06:24+00:00

H=4 and H=6 indicate the height of the diamond tip before it’s sharpened. The height of the tip in turn affects the number of sharpening processes that can be applied. As a rough example: H=4 allows on average 6/8 sharpening interventions, or 8/12 in the case of H=6.
