1. Product Overview

The WNMG080404PS is a premium-grade indexable carbide turning insert manufactured by Kyocera Corporation under the CA525 CVD-coated grade designation. Engineered for semi-finishing and medium turning, this insert delivers exceptional dimensional stability, superior surface finish quality, and extended edge life in demanding CNC turning environments.

With its 80° rhombic (WNMG) negative geometry and precision-ground cutting edges, the WNMG080404PS is the insert of choice for machinists seeking reliability and repeatability in high-volume production settings.

4. Grade Details — CA525 Key Characteristics

The CA525 grade is a high-performance CVD-coated carbide specifically developed for steel machining. Its multi-layer coating architecture combines a thick TiCN layer with an Al₂O₃ top coat, delivering outstanding wear resistance and thermal stability.

  • Substrate: Fine-grained tungsten carbide (WC-Co) with optimized cobalt content for toughness
  • Coating Structure: TiCN (interlayer) + Al₂O₃ (outer layer) + TiN (gold top layer for wear detection)
  • Color Code: Gold-yellow (TiN surface finish)
  • ISO Application Range: P15-P35 (Steel, cast steel, long-chipping materials)
  • Cutting Speed Capability: Up to 350 m/min in continuous cutting of carbon steel
  • Temperature Resistance: Effective up to 900°C at the cutting edge

7. Recommended Applications & Workpiece Materials

The WNMG080404PS with CA525 grade is optimized for the following material groups and application scenarios:

  • Carbon Steels: C35, C45, C60, 1045, 1050 — excellent chip control and surface finish
  • Alloy Steels: 4140, 4340, 16MnCr5, 20MnCr5 — balanced wear and toughness
  • Tool Steels: H13, D2, O1 — moderate speed, high wear resistance
  • Cast Steels: GS-52, GS-60 — reliable performance in scaled surfaces
  • Stainless Steels (Limited): 304, 316L at reduced speeds with adequate coolant

9. Recommended Cutting Conditions

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

Depth of Cutap0.3-2.5mm
CoolantEmulsion (5-8%) or neat oil
Tool OverhangMinimum possiblemm

10. Operating Guidelines

  • Toolholder Selection: Use negative-type WNMG toolholders (e.g., DWLNR, MWLNR series) with 0° clearance and adequate rake angle for the operation.
  • Clamping Torque: Tighten the insert screw to 3.5–4.5 N·m. Over-tightening may distort the insert seat; under-tightening causes vibration.
  • Coolant Delivery: Direct high-pressure coolant to the cutting zone. For PS chipbreaker, aim at the chip groove to enhance chip breaking.
  • Edge Inspection: Check for flank wear (VB max 0.3 mm) and crater wear. Replace when surface finish degrades or cutting force increases audibly.
  • Entry Angle: Maintain a lead angle of 75°–95° for optimal chip control and reduced radial forces.
  • Workpiece Runout: Ensure runout is below 0.02 mm for precision applications to prevent chipping.

11. Toolholder Compatibility

The WNMG080404PS is compatible with standard ISO toolholders designed for WNMG 08 inserts. Recommended holder families include:

Holder SeriesStyleApproach AngleUse Case
DWLNR / DWLNLExternal, 95°95°General external turning and facing
MWLNR / MWLNLExternal, 95°95°Heavy-duty machining
PWLNR / PWLNLExternal, 95°95°Precision finishing
EWLNR / EWLNLInternal, 95°95°Boring and internal turning
SWLNR / SWLNLExternal, 45°45°Profiling and facing

Note: Verify holder seat dimensions (IC 12.7 mm, thickness 4.76mm) before ordering. Use Kyocera genuine toolholders for best performance.
