DESCRIPTION

TNMG160412-MA CVD Coated Carbide Turning Insert for Steel Machining

Product Overview

The TNMG160412-MA is a high-performance CVD-coated carbide turning insert designed for superior steel machining applications. Featuring an advanced multi-layer coating system, this insert delivers exceptional wear resistance and extended tool life in roughing to finishing operations.

Key Features

✔ Premium CVD Coating (TiCN/Al₂O₃/TiN) for maximum abrasion resistance
✔ Optimized Chipbreaker Geometry for excellent chip control
✔ Negative Rake Design (7° relief angle) for stable heavy-duty cutting
✔ High-Temperature Resistance - maintains hardness up to 1200°C

Performance Benefits

✓ 30-50% longer tool life vs. standard grades
✓ Higher feed rates (up to 0.4mm/rev in steel)
✓ Improved surface finish (Ra 1.6μm achievable)
✓ Reduced cutting forces for better machining stability

Recommended Applications

• Carbon steels (1045, S45C)
• Alloy steels (4140, 4340)
• Continuous and interrupted cutting
• Medium to heavy roughing operations

Quality Assurance

◇ ISO 9001 certified production
◇ 100% dimensional inspection
◇ Batch traceability

Ordering Information

• Standard packaging: 10 inserts/box

• MOQ: 5 boxes (50 inserts)

CNC Inserts - Frequently Asked Questions

1. How do I choose the right grade for my specific machining application?

Choosing the correct grade is crucial for tool life and performance. We provide a comprehensive Grade Cross-Reference Chart that maps our CD Carbide grades to major international brands like Sandvik, Mitsubishi, and Kyocera. If you are unsure, simply provide us with the workpiece material (P, M, K, S, H) and machining conditions, and our engineers will recommend the best solution.

2. Can you provide customized CNC tools based on our drawings?

Yes. As a factory-direct manufacturer, we specialize in bespoke engineering. Whether you need non-standard dimensions, specific chipbreakers, or customized coatings for unique alloys, our technical team can develop products based on your technical drawings (PDF/STEP) or physical samples.

3. Do you offer free samples for testing before bulk orders?

We understand that "trial cutting" is the only way to verify tool stability. We offer sample packs for professional buyers to test performance on their own CNC machines. Please contact our sales team with your machine specifications and the material you are processing to request your trial samples.

4. How do you ensure the quality consistency of your carbide inserts?

Our quality control is integrated into every step of the production process in Zhuzhou. We use high-purity tungsten carbide powder and advanced PVD/CVD coating equipment. Each batch undergoes rigorous inspection, including microscopic edge analysis and hardness testing, to ensure that the performance of the 1,000th insert is identical to the 1st.

5. What is the typical lead time for international B2B orders?

For standard models in stock (such as WNMG, CNMG, etc.), we usually ship within 3-5 business days. For customized tools or large-volume OEM orders, the production cycle typically ranges from 2 to 4 weeks, depending on the complexity of the design and coating requirements.

6. Are you a manufacturer or a trading company?

We are a direct manufacturing enterprise based in Zhuzhou, the hunan of China’s tungsten carbide industry. By cutting out the middleman, we provide factory-direct pricing and faster technical support. This allows us to offer more flexible MOQs (Minimum Order Quantities) for small-to-medium-sized distributors and specialized machine shops.
