7. Recommended Applications & Workpiece Materials

Workpiece Material Machinability Cutting Speed (Vc) Notes
Carbon Steel (C35, C45, C60) Excellent 120-280 m/min Primary application
Alloy Steel (42CrMo4, 34CrNiMo6) Excellent 100-220 m/min Heat-treated up to 35 HRC
Tool Steel (1.2379, 1.2343) Good 80-160 m/min Annealed condition

Stainless Steel (304, 316) Fair 60-120 m/min Not recommended for prolonged use

8. Application Map by Operation

Operation Suitability Conditions
External Turning Excellent Interrupted cuts, cast skin
Heavy Roughing Excellent High DOC, high feed
Facing Good Robust entry conditions
Step Turning Good Shoulder machining

9. Recommended Cutting Conditions

Parameters below are starting recommendations for continuous cutting of C45 carbon steel using coolant. Adjust based on machine rigidity, workpiece condition, and desired surface finish.

Parameter Minimum Recommended Maximum
Cutting Speed (Vc) 130 m/min 180 m/min 230 m/min
Feed Rate (fn) 0.4 mm/rev 0.57 mm/rev 0.75 mm/rev
Depth of Cut (ap) 3.0 mm 4.5 mm 6.0 mm

10. Operating Guidelines

  • Coolant: Recommended for most steel applications to extend tool life and improve surface finish. Use water-miscible coolant at 6–8% concentration.
  • Entry/Exit: For interrupted cuts, reduce cutting speed by 15–25% to minimize thermal shock and edge chipping.
  • Tool Overhang: Keep toolholder overhang to minimum (≤ 1.5× holder height) to maintain rigidity and reduce vibration.
  • Insert Seating: Ensure insert seat and pocket are clean before mounting. Torque clamping screw to 2.5–3.5 N·m for M3.5 screws.
  • Edge Wear Monitoring: Replace insert when flank wear (VB) reaches 0.3 mm or when crater wear (KT) exceeds 0.15 mm to maintain dimensional accuracy.
  • Storage: Store inserts in original packaging away from direct sunlight and moisture. Avoid contact between sharp edges.
