Recommended Cutting Conditions

Starting Parameters for KW10
Cutting Speed (Vc)80–250 m/min
Feed Rate (f)0.05–0.25 mm/rev
Depth of Cut (ap)0.1–2.0 mm
Coolant RecommendationWet cutting with water-soluble coolant recommended
Workpiece ConditionContinuous or lightly interrupted cuts

Parameters are starting recommendations. Optimize based on machine rigidity, workpiece condition, and surface finish requirements. Reduce speed by 15–20% for interrupted cuts or scale formation.

Operating Guidelines

  • Ensure toolholder pocket is clean and free of burrs before insert seating.
  • Torque clamping screw to manufacturer specification (typically 2.5–4.5 N·m for M2.5–M4 screws).
  • Use precision collet or hydraulic chuck for boring bars to minimize runout.
  • For uncoated carbide: use adequate coolant flow to prevent built-up edge on aluminum and titanium.
  • Inspect insert after initial passes; adjust feed if chip color indicates excessive heat.
  • Store inserts in original packaging away from moisture and corrosive atmospheres.

Toolholder Compatibility

The FMN is compatible with the following Kyocera and standard ISO toolholders:

FMN dedicated grooving toolholders (external/internal)

Verify pocket angle (typically ° for 60 degree triangle inserts) and clamp type (lever-lock, pin-lock, or top-clamp) match your holder design. Contact Kyotow.com technical support for holder selection assistance.
