1. Choose The Series By Cutting Condition
F series is more adaptable for mixed materials, older equipment and less ideal chip control. V series is used for faster, heavier cutting and stronger life requirements. S series is closer to light cutting and is useful for sticky materials, cleaner finish and stable equipment.
2. Treat Coating As A Performance Multiplier
PVD coating can reduce friction, lower tooth tip temperature and improve cutting life on suitable materials. However, coating cannot solve wrong tooth count, poor clamping, chip build-up, bad oil mist or machine maintenance problems.
3. Check Machine Condition Before Test Cutting
Confirm the wire brush can remove chips, oil mist reaches the cutting surface, air blowing removes inner tube chips, the clamp holds the material, the flange and machine head are clean, and the blade is installed without forced pressure.
4. Diagnose Abnormal Damage
| Symptom | Likely Check Points |
|---|---|
| Broken teeth | Chip build-up, poor brush, loose cover, bad clamping, impurities, cone end or burr end material. |
| Cutting skew | Runout, chip stuck between blade and tips, wrong parameters, too many teeth or dull blade. |
| Sticky chips | Oil mist, sticky material, insufficient lubrication, weak chip evacuation or repeated chip cutting. |
| Short life | Material hardness, coating choice, tooth count, feed, speed, coolant and machine maintenance. |
5. Record Data Before Comparing Blades
A serious cermet blade test should record current blade performance, test blade performance, material grade, diameter, speed, feed, oil condition, cut surface and final blade damage state. Without comparable data, the test result is difficult to judge.
