Wolframkarbid-Schneiden mit Diamantdrahtsäge
- Tungsten carbide ranks 9-9.5 auf der Mohs-Skala – nur Diamant ist härter – was EDM langsam macht, Laserschneiden thermisch schädigend, und Schleifsägen, die schnell verschleißen.
- Eine Diamantdrahtsäge kombiniert einen hochfesten Draht mit Diamantkorn, ein präzises Führungssystem, Kühlmittel- und CNC-Steuerung, um mit Mikrometergenauigkeit durch Wolframkarbid zu schleifen.
- Kerf so niedrig wie 0.2 mm maximiert die Nutzung teurer Wolframkarbidrohlinge, und das kühlmittelgekühlte Verfahren verhindert die Mikrorisse, die thermische Methoden erzeugen.
- Diamond wire lasts significantly longer than abrasive blades, delivering a lower cost-per-cut and supporting high-volume industrial production.
- Key beneficiary industries: tool and die manufacturing, semiconductors and electronics, aerospace and defense, medical devices and renewable energy.
In der Welt des Präzisionsschneidens, Wolframkarbid (WC) gilt aufgrund seiner extremen Härte und Verschleißfestigkeit als einer der am anspruchsvollsten zu verarbeitenden Werkstoffe.

Why Tungsten Carbide is a Challenge to Cut
Tungsten carbide is widely used in industrial applications due to its exceptional properties:
– Extrem harte (9-9.5 Mohs scale) – Only diamonds are harder
– High wear resistance – Causes rapid tool degradation
– Brittleness – Prone to cracking under improper cutting forces
Traditional cutting methods like EDM (Funkenerosion), Laserschneiden, and abrasive saws face limitations:
- Slow processing speeds
- Hoher Werkzeugverschleiß & replacement costs
- Thermal damage risks
- Limited precision in thin cuts
This is where diamond wire saw cutting machines step in as the superior alternative.
How Diamond Wire Saw Cutting Machines Work
A diamond wire saw cutting machine uses a high-tensile wire embedded with diamond abrasive particles to slice through hard materials with minimal kerf loss and maximum efficiency.
Key Components:
- Diamond-Coated Wire – The cutting medium with synthetic diamond grit
- Wire Guidance System – Ensures precise tension and alignment
- Coolant System – Prevents overheating and extends wire life
- CNC Control – Enables automated, high-precision cuts
Schneidprozess:
– The wire moves in a continuous loop at controlled speeds
– Diamond particles grind through the tungsten carbide
– Coolant flushes away debris and reduces friction
– Minimal material waste due to ultra-thin kerf (bis zu 0,2 mm)

Häufig gestellte Fragen
Why is tungsten carbide so difficult to cut?
Tungsten carbide has extreme hardness of 9-9.5 auf der Mohs-Skala, so only diamond is harder. Its high wear resistance causes rapid tool degradation, and its brittleness makes it prone to cracking under improper cutting forces. Traditional methods like EDM, laser cutting and abrasive saws suffer from slow speeds, high tool wear, thermal damage and limited precision on thin cuts.
Zuletzt überprüft: September 2026
Can a diamond wire saw cut tungsten carbide without thermal damage?
Ja. Diamond wire cutting is a coolant-cooled process, so unlike laser cutting or EDM it creates no heat-affected zone and prevents the micro-cracks that thermal stress causes. The material’s microstructure and properties remain intact.
What kerf width can a diamond wire saw achieve on tungsten carbide?
The ultra-thin diamond wire produces a kerf as low as 0.2 Mm. This minimal material waste is critical when slicing costly tungsten carbide blanks, dünne Wafer, rods and intricate geometries.
How does diamond wire cutting compare with EDM for tungsten carbide?
Diamond wire cutting is faster, causes no thermal damage, and achieves micron-level accuracy on complex shapes. Unlike EDM, which only works on electrically conductive materials, a diamond wire saw is material-agnostic and can cut any hard, brittle material. Tool wear costs are also lower because diamond wire outlasts conventional tooling.
Which industries use diamond wire saws for tungsten carbide?
Five main ones: tool and die manufacturing for carbide inserts, end mills and drills; semiconductor and electronics for substrates and microelectronic components; aerospace and defense for wear-resistant coatings and turbine components; medical device production for surgical tools and implants; and renewable energy for solar cell cutting wires and hard-facing materials.
