Unlocking Efficiency in Roll Machining with Solid CBN Technology
Industrial rolls demand extreme machining precision and tool durability.
These case studies demonstrate how our solid CBN inserts outperform conventional solutions in processing ultra-hard roll materials.
Case 1: Turning Narrow Strip Steel Rolls (HSD67 Hardness)
Challenge: Machining indefinitely chilled cast iron rolls (HSD67 hardness) with consistent tool life.
Solution: Solid CBN Insert RNMN200800
Parameters:
- Cutting Speed (Vc): 56-76 m/min
- Feed Rate (Fr): 0.5 mm/rev
- Depth of Cut (ap): 2 mm
- Dry Machining
Result:
60-minute tool life - enabling continuous processing of narrow strip steel rolls with reduced downtime.
Case 2: Grooving High-Hardness Rolls (HSD90 Hardness)
Challenge: Extending blade life in grooving applications on HSD90 hardness rolls.
Solution: Solid CBN Insert RCMX120700
Parameters:
- Cutting Speed (Vc): 35 m/min
- Feed Rate (Fr): 0.2 mm/rev
- Dry Machining
Result:
25 grooves per cutting edge - twice the industry average for comparable CBN tools.
Case 3: Turning Carbide Rolls (HRC 85 Hardness)
Challenge: Maintaining tool integrity when machining carbide rolls at HRC 84.5-85 hardness.
Solution: Solid CBN Insert RNMN120400
Parameters:
- Cutting Speed (Vc): 25 m/min
- Feed Rate (Fr): 1.02 mm/rev
- Depth of Cut (ap): 0.6 mm
Result:
5x longer tool life vs. premium imported CBN inserts when processing outer diameters.
