Tool: SNGA120412 CBN Insert  
 
Parameter Value Quality Impact
Cutting Speed (Vc) 373 m/min Prevents work hardening
Feed per Rev (Fn) 0.1 mm/rev Mirror surface finish (Ra≤0.2μm)
Depth of Cut (Ap) 0.5 mm minimizes residual stress
Number of Passes 4 ±0.01mm dimensional accuracy

Alloy-TiC Guide Rollers

 

7 Operational Benefits of Alloy-TiC Guide Roller
(Validated in Steel Production Lines)
 
Ⅰ. 50% Longer Groove Service Life.
→ CBN-machined Alloy-TiC Guide Roller surface reduces groove wear → Extends roller replacement intervals by 2 times
 
Ⅱ. Lower Regrinding Costs.
→ Ultra-hard surface (HRC 70+) → 60% less material removal needed per regrind
 
Ⅲ. Decreased risk of bearing breakage and failures.
 
Ⅳ. Consistent Product Dimensions.
 
Ⅴ. No Roller Breakage During Rolling.
 
Ⅵ. Oxidation Resistance at 800°C.
→ Non-stick TiC surface → Prevents scale buildup during hot rolling
 
Ⅶ. 15% Increased Mill Output.
→ Fewer roller changes → Over 200 extra hours of production annually
