Wire Saw for Metal — Cold Precision Cutting
Wire Saw for Metal
Cold. Clean. Precise.
Abrasive diamond wire cutting with no thermal distortion or burr formation — purpose-built for stainless steel, titanium, copper, and exotic alloys.
Cutting Principle
Diamond Wire Saw vs. Conventional Metal Cutting Methods
No heat-affected zone, no recast layer — critical for precision metal sample prep and optics substrate machining.
Material Compatibility
Metal Types Suitable for Diamond Wire Cutting
From ductile aerospace alloys to brittle precious metals — diamond wire delivers consistent, burr-free cuts across the full metallic spectrum.
Cutting Characteristics
Why Cold Wire Cutting Changes Everything for Metal
Zero Thermal Damage
No heat-affected zone. Critical for titanium, Inconel, and heat-sensitive alloys.
Burr-Free Surface
Chip-free, burr-free edges — eliminating deburring steps for aerospace and medical components.
Precision Sample Prep
Ideal for metallographic sections and SEM/TEM prep. Preserves microstructure integrity.
Coolant-Assisted
Water-based or light oil prevents oxidation — critical for titanium, aluminum, and copper.
Super fast cutting speed
Compare to EDM wire cutting, endless diamond wire saw can cut 10 times faster

FAQ
Common Questions About Wire Saw for Metal
Yes. Diamond wire saw machines cut stainless steel grades including 304, 316L, and 440C with excellent surface finish. The cold abrasive mechanism avoids work hardening. Typical feed rate for 304 SS (20mm rod) is 0.3–0.8 mm/min with water-based coolant.
Water-based coolant with rust inhibitor additives (pH 8–9) is recommended for stainless steel. For titanium and reactive metals, light mineral oil is better. Vimfun machines include a closed-loop coolant recirculation system compatible with both types.
Diamond wire saw achieves Ra 2–5 μm — not better than EDM (Ra 0.4–1.6 μm). But Unlike EDM, endless diamond wire saw can cut super fast.
Yes. Tungsten (HV ~3400) and molybdenum (HV ~1500) can be sectioned without thermal cracking. Feed rates are slow (0.1–0.3 mm/min) but the result is crack-free, burr-free surfaces suitable for further analysis.Further more, we have a clients who cut Powder metallurgy containing tungsten
