Advanced Grade: VP15TF (PVD Miracle Coating)

The VP15TF grade is Mitsubishi's premier PVD solution, often called the "Miracle" grade for its ability to cut almost anything. By combining a high-toughness micro-grain carbide substrate with a specialized AlTiN-based coating, it offers extreme resistance to welding and chipping. This makes it an ideal multi-material indexable carbide insert that maintains a sharp edge even when interrupted cuts or thermal shocks are present.

MS Chipbreaker Geometry

The MS (Medium-Sharp) chipbreaker provides an excellent balance between edge sharpness and structural integrity. In precision turning, the MS geometry effectively breaks chips in both gummy stainless steels and harder alloy steels, preventing "bird-nesting" and ensuring a smooth, uninterrupted CNC turning process.

Recommended Cutting Parameters

General Recommendations (Vary by Material Type):

  • Steel (P): Vc 100-220 m/min | f 0.15-0.35 mm/rev
  • Stainless (M): Vc 80-180 m/min | f 0.12-0.30 mm/rev
  • Cast Iron (K): Vc 100-180 m/min | f 0.15-0.35 mm/rev
  • Depth of Cut (ap): 0.5 - 3.5 mm

*Pro Tip: For stainless steel applications, use ample coolant to maximize the PVD coating benefits.*

Technical Q&A

Q: Why choose VP15TF over a CVD grade like US735?

A: VP15TF offers a sharper edge and better toughness against chipping, making it better for finishing and interrupted cuts across multiple materials.

Q: What is the maximum depth of cut for this insert?

A: For the WNMG080408, the recommended maximum depth of cut (ap) is approximately 3.5 mm to ensure stable machining and chip breaking.

Q: Is this insert suitable for dry cutting?

A: While it can handle dry cutting in steels, we highly recommend wet cutting for stainless steel to prevent work hardening and extend edge life.

Expert Choice Tip: VP15TF vs MC7025

For General Purpose Multi-Material work, VP15TF is your best choice. For High-Volume Stainless Steel production with stable setups, consider MC7025 for higher cutting speeds.
