Just tell us which carbide inserts you are looking for and our team will help you hold the palm.
Suitable materials such as tungsten carbide, ceramics, or high-speed steel are selected based on the blade’s application. These materials must offer high hardness and wear resistance.
Metal powders are mixed in precise ratios, pressed into shape, and then sintered at high temperatures to form blade blanks.
From importing presses to stamp out blade blanks, to subsequent sintering and coating, every step is strictly controlled, all to provide customers with stable and reliable blade solutions
Specifically designed for pressing various types of turning tool blanks, it enhances blade density and lifespan stability, ensuring more consistent batch dimensions and a more reliable cutting process.
The insert undergoes precision grinding and cleaning before being subjected to PVD/CVD vacuum coating, forming a multi-layered hard coating structure that combines high hardness, wear resistance, and stable lifespan.
The insert edge is finely passivated to remove small dents and burrs, improve the strength and stability of the insert edge, and thus extend the service life of the insert.
At HNCarbide, our MGMN grooving inserts are packaged with strict protection standards to ensure each insert reaches you in perfect condition.
Every MGMN insert is securely stored in an impact-resistant case and clearly identified with the correct MGMN width code, insert dimensions, and model number to prevent mix-ups during production or warehouse handling.
Before shipping, each case is sealed in a moisture-proof protective layer to prevent corrosion and contamination during long-distance transport.
For bulk quantities, we reinforce the packaging with heavy-duty cartons or wooden crates to keep your MGMN inserts safe during international shipping and high-load logistics.
HNCarbide cooperates with reliable freight partners to make sure your MGMN grooving inserts arrive quickly, safely, and ready for immediate machining use—whether shipped by air, sea, or express courier.
