Mitsubishi Materials | AJX Series Heavy-Duty High-Feed Milling
The Mitsubishi JDMT140520ZDSR-JM VP15TF is an industrial-grade high-feed milling insert engineered for the AJX14 cutter series. As a larger format insert, it is the primary choice for heavy-duty roughing and high metal removal rates (MRR) in large components. Featuring the advanced VP15TF Miracle PVD coating, this insert excels in Stainless Steel, Carbon Steel, and Alloy Steels, providing exceptional edge toughness and thermal resistance during prolonged milling cycles.

| Grade / Coating | VP15TF (Miracle PVD Coated) |
VP15TF Miracle Coating
The VP15TF grade utilizes Mitsubishi's "Miracle Coating" technology. It combines a high-toughness substrate with a PVD coating that creates a barrier against heat and chemical wear. It is particularly effective at preventing built-up edge (BUE) in gummy materials like 300-series stainless steel.
JM Chipbreaker Strategy
The JM (General Machining) chipbreaker is designed for balanced performance. Its strengthened cutting edge is built to withstand the high feed per tooth characteristic of the AJX system, ensuring chip thinning and effective evacuation to prevent vibration and tool failure.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed ($v_c$) | Feed Per Tooth ($f_z$) |
