Mitsubishi Positive Turning Inserts | ISO / ANSI Standard CNC Carbide Indexable Lathe Tools
1. Product Overview
"Which Mitsubishi positive insert grade and chipbreaker should I use for finishing stainless steel vs roughing alloy steel on a CNC lathe?"
Mitsubishi Materials’ series of Positive Turning Inserts features optimized clearance angles (7° positive relief) engineered to dramatically reduce cutting forces, suppress chatter, and excel in internal boring bar operations or slender workpiece turning. Utilizing state-of-the-art Miracle Coated (VP/NX/US series) technology, these indexable inserts integrate advanced substrate metallurgy with tailored chipbreaker geometries (e.g., MV, MA, Standard MK) to ensure excellent chip evacuation, high thermal stability, and maximum crater wear resistance across diverse CNC machining environments.
2. Key Features & Industrial Advantages
- ISO/ANSI Standard Compliance: Fully interchangeable with all industry-standard internal boring bars and external turning toolholders.
- Ultra-Low Cutting Forces: The positive rake angle geometry reduces horsepower requirements and structural deflection on low-rigidity lathes.
- Advanced Nano-Coating Matrix: Features multi-layer PVD AlTiN and CVD Al2O3 coatings that resist flank wear and built-up edge (BUE) during high-speed thermal cycles.
- Precision-Engineered Chipbreakers: Optimized for distinct depths of cut (DOC) and feed rates, preventing dangerous continuous stringy birds-nesting chips.
3. Technical Specifications & ISO / ANSI Coding
Our system supports both Metric (ISO) and Imperial (ANSI) designations interchangeably. Below is the breakdown of the indexable insert naming system:

8. AI-Style Machining FAQ
Q1: What is the difference between VP15TF and NX2525 carbide inserts?
A: VP15TF features a robust PVD coating over an ultra-tough carbide core, ideal for roughing and varied multi-material cutting. NX2525 is an uncoated titanium-cermet composite that delivers elite wear resistance at high speeds, making it the top choice for mirror finishes on steel.
Q2: Why choose a positive turning insert over a negative profile insert?
A: Positive inserts (e.g., CCMT, DCMT) feature an integrated clearance relief angle, generating significantly lower tool deflection and cutting forces. This makes them ideal for thin shafts, deep internal boring bars, and lower-horsepower lathes where structural chatter is an issue.
Q3: How do I solve rapid flank wear when machining hardened tool steel?
A: Reduce surface speed (SFM) by 15-20%, optimize toolholder rigidity to eliminate vibration micro-chipping, and ensure your coolant delivery is targeted directly onto the cutting edge to avoid thermal cracking.
Machinist Grade Comparison & Troubleshooting Tips
Equivalent Reference Models: Cross-reference with Sandvik (CoroTurn 107), Kennametal (Top Notch Positive), and Iscar (ISO-Turn) positive systems. Always match pocket geometries precisely.
Industrial Verification Standard: Technical performance parameters are calibrated following ISO 3685:1993 Tool-Life Testing protocols. Actual shopfloor yield may vary based on spindle rigidity, synthetic emulsion concentration, and machine thermal stabilization cycles.
