DNGA CNGA SNGA TNGA VNGA WNGA CNC CBN Inserts for Superhard Materials

Product description

Introduction to CBN inserts

Welded cubic boron nitride blade

The tip is made of cubic boron nitride material, and the intermediate matrix is made of cemented carbide material. The CBN tip provides high hardness, high wear resistance and good thermal stability for cutting processing; the cemented carbide matrix has high strength and toughness, can withstand cutting force and impact, and provides reliable support for the CBN tip. There is a center hole for positioning, which can replace the coated blade. Common models include CNGA, SNGA, VNGA, etc.

Features of tungsten carbide CBN insert

Performance characteristics

1.High hardness and wear resistance: The hardness is second only to diamond, up to 3000-5000HV, suitable for processing high-hardness ferrous metal materials, such as hardened steel, mold steel, etc.

2.Good thermal stability: The heat resistance can reach 1400-1500℃, which is twice as high as the heat resistance of diamond, and can be used for high-speed turning.

3.Good chemical stability: It will not react chemically with iron materials at 1200-1300℃, and there will be no sharp wear during high-temperature cutting.

4.Good thermal conductivity: Much higher than high-speed steel and cemented carbide, which is conducive to reducing the temperature of the cutting area and reducing diffusion wear.

Low friction coefficient: The cutting force generated during cutting is small, which can effectively improve the surface quality.

The application areas of CBN insert

Automobile manufacturing: commonly used for processing engine parts and transmission system parts, such as high-speed hard turning of hardened steel gears, bearings, and crankshafts, which can replace grinding.

Aerospace: used to process difficult-to-process materials such as titanium alloys and nickel-based superalloys, such as high-temperature alloy material processing of turbine engine blades.

Mold manufacturing: can achieve efficient processing of hard mold steel (HRC 45 or above), improve processing accuracy and surface finish.

Heavy machinery manufacturing: used for processing high-strength steel parts required in large equipment, such as rough and fine processing of chilled cast iron rolls and high-chromium cast iron.

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.
