Product Overview

The WNMG080412GT is a premium-grade cnc turning insert from Kyocera, featuring the advanced CA525 PVD-coated carbide substrate. This WNMG negative insert with 1.2mm corner radius and high-speed finishing geometry (GT) is engineered for high-speed finishing of steel. The 12.7mm inscribed circle and 4.76mm thickness provide excellent edge stability and chip control across a wide range of cutting parameters. Ideal for modern CNC turning centers requiring consistent tool life and dimensional accuracy.

Chipbreaker Profile

GT Chipbreaker – High-speed finishing geometry with optimized rake face and minimal cutting resistance. Ideal for high-speed CNC turning with excellent chip evacuation.

ParameterRange
Recommended Feed (fn)0.08 – 0.30 mm/rev
Depth of Cut (ap)0.2 – 2.0 mm

Recommended Applications & Workpiece Materials

The WNMG080412GT grade CA525 is suitable for the following materials:

  • Carbon steel, alloy steel, free-machining steel, stainless steel, high-speed finishing applications
  • Hardness range: ≤ 350 HB (optimal), up to 45 HRC with reduced parameters
  • Surface condition: Pre-machined, as-cast, or as-forged (roughing geometries)

Application Map by Operation

Recommended machining operations for the GT geometry:

  • High-speed finishing, thin-walled parts, precision contouring, CNC automated turning

Recommended Cutting Conditions

Starting parameters for GT geometry with CA525 grade. Adjust based on machine rigidity and workpiece condition:

Workpiece MaterialCutting Speed Vc (m/min)Feed fn (mm/rev)Depth of Cut ap (mm)
Carbon Steel (≤ 300 HB)180 – 2800.08 – 0.30 mm/rev0.2 – 2.0 mm
Alloy Steel (300-400 HB)120 – 2000.08 – 0.30 mm/rev0.2 – 2.0 mm
Stainless Steel (AISI 304/316)100 – 1600.08 – 0.30 mm/rev0.2 – 2.0 mm
Cast Iron (GG25/GGG40)150 – 2200.08 – 0.30 mm/rev0.2 – 2.0 mm
Tool Steel (40-50 HRC)60 – 1000.05 – 0.150.2 – 0.8

Operating Guidelines

  • Toolholder Selection: Use negative rake toolholders (e.g., WNMG holders) with 0° or 5° inclination for optimal performance.
  • Coolant Recommendation: High-pressure coolant (70+ bar) recommended for chip evacuation in deep cavities and stainless steel.
  • Edge Preparation: CA525 features honed T-land edge preparation (0.02-0.05mm) for improved edge stability.
  • Run-in Procedure: Reduce cutting speed by 20% for the first 5 minutes to stabilize the coating and substrate interface.
  • Tool Life Monitoring: Monitor flank wear (VB). Recommended tool change at VB = 0.3mm for roughing, VB = 0.15mm for finishing.
  • Chip Control: Ensure chipbreaker geometry matches feed rate. Adjust coolant nozzle to direct flow at the cutting zone.
