Enhanced Wear Resistance of Diamond Blades in High-Temperature Alloy Casting Machining: Real-World Performance Test Results

Why Wear Resistance Matters in Diamond Saw Blades for High-Temperature Alloy Castings

In high-temperature alloy casting applications, the cutting performance of diamond saw blades is not just about sharpness—it’s about consistency under extreme conditions. Traditional blades often fail prematurely due to thermal softening and rapid abrasion when processing materials like gray cast iron and ductile cast iron. This article presents real-world test data from UHD's advanced diamond saw blade series, showing how vacuum sintering technology delivers measurable improvements in tool life, cost efficiency, and process stability.

Test Setup: Real Conditions, Real Results

The experiment was conducted using a standard CNC vertical milling machine (Model: DMG MORI DMU 50) at ambient temperature (25°C) with continuous feed rate of 12 m/min. Two material types were tested: gray cast iron (ASTM A48 Grade 30) and ductile cast iron (ASTM A536 Grade 65-45-12). Key metrics included:

• Wear rate per meter cut (mm/m)
• Fluctuation in cutting force (N)
• Surface roughness (Ra, μm)

“We switched to UHD’s diamond blades after two months of failed trials with other brands. The difference isn’t just longer life—it’s predictable cuts every time.”
—— Mark Chen, Head of Process Engineering, Zhejiang Casting Co.

What Makes UHD Different? Vacuum Sintering + Precision Grain Distribution

Unlike conventional brazed or electroplated methods, UHD uses a controlled vacuum sintering process that ensures uniform grain distribution and stronger bonding between diamond particles and the metal matrix. This translates into:

• Up to 3x longer tool life compared to standard blades
• Consistent cutting force over extended use (reducing machine wear)
• Lower surface finish variation—critical for precision casting parts
