V. What Applications Are Suitable for Peach-Shaped Turning Tools?
CNC lathe external cylindrical turning, face turning, and step turning
Rough Machining and Semi-finish Machining of Workpieces
Machining of conventional materials such as carbon steel, stainless steel, cast iron, and alloy steel
Machining of general structural components such as shafts, discs, and sleeves
Batch production scenarios involving continuous cutting and medium-depth cuts, balancing rigidity and stability.
VI. Turning Inserts WNMG Frequently asked questions?
Q1： WNMG Why are blades prone to chipping?
Answer: This is mainly caused by excessively high cutting parameters, significant impact from intermittent cutting, insufficient insert toughness, or poor machine tool rigidity and excessive vibration.
Q2 : What should be done about tool sticking and chip entanglement when machining stainless steel?
Answer: Reduce the spindle speed slightly, increase the feed rate, select carbide inserts with a coating specifically designed for stainless steel, and ensure adequate cooling.
Q3： WNMG080404 and 080408 What's the difference?
Answer: The last two digits represent the nose radius. 04 Yes. R0.4，08 Yes. R0.8， R The larger the angle, the higher the strength and wear resistance.
Q4： WNMG Can the blade be inserted into the car’s interior?
Answer: Yes, it’s possible, but it’s more suitable for external cylindrical surfaces and end faces; for internal bores, we recommend using smaller sizes. CCMT 、 VCMT Series of blades.
Q5： WNMG What causes rapid blade wear and a short service life?
Answer: Cutting speed is too high, cooling is insufficient, or the insert material and coating are incompatible with the workpiece material.
