Primary operations include: Boring, External Turning, Facing, Internal Facing.
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| External Turning | ★★★★★ Excellent | Primary design intent — optimized external turning performance |
| Internal Turning | ★★★★☆ Very Good | Suitable with appropriate boring bar |
| Boring | ★★★★★ Excellent | Primary design intent — optimized boring performance |
| Facing | ★★★★★ Excellent | Primary design intent — optimized facing performance |
| Chamfering | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Copying | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Back Boring | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Grooving | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
| Milling | ★★☆☆☆ Limited | Not recommended — select alternative geometry |
Recommended Cutting Conditions
| Starting Parameters for A65 | |
|---|---|
| Cutting Speed (Vc) | 150–800 m/min |
| Feed Rate (f) | 0.08–0.30 mm/rev |
| Depth of Cut (ap) | 0.2–3.0 mm |
| Coolant Recommendation | Wet or dry (compressed air preferred for ceramics) |
| Workpiece Condition | Continuous 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 ceramic grades: maintain rigid setup; avoid manual feed engagement at high speed.
- 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 CNG is compatible with the following Kyocera and standard ISO toolholders:
Standard ISO toolholders with compatible pocket geometry
Verify pocket angle (typically 80° for 80 degree diamond inserts) and clamp type (lever-lock, pin-lock, or top-clamp) match your holder design. Contact Kyotow.com technical support for holder selection assistance.
