Cermet are widely used in various industries due to their excellent performance, but their grinding difficulty is often difficult. Although the hardness of metal ceramics is similar to that of cemented carbide, its processing challenges mainly come from high density and low thermal conductivity. This article will explore the characteristics of metal ceramic grinding and how to choose the right grinding wheel and binder to improve processing efficiency.
1. High density and low affinity: Metal ceramics have high density and poor reactivity with other materials, which makes it difficult for the grinding wheel to "tear" the surface during grinding, resulting in slippage. This makes the grinding process more difficult.
2. Low thermal conductivity: The heat generated during the grinding process is difficult to dissipate quickly, which easily leads to thermal stress accumulation, resulting in blade burrs and edge collapse. Therefore, appropriate cooling measures need to be taken during the grinding process to ensure that the workpiece temperature is controlled within a reasonable range.
When grinding cermet materials, diamond abrasive grinding wheels must be used. However, which bond diamond grinding wheel is more suitable for processing cermet workpieces? Let's take a look at what grinding wheels Moresuperhard 's customers use:
Customer 1: Double-end grinding cermet inserts, using ceramic bond diamond double-end grinding wheels.
Customer 2: Grinding of cermet milling cutters, using resin bond diamond grinding wheels for grinding on tool grinders.
Customer 3: Slotting of cermet thread cutters, using hybrid bond diamond flute grinding wheels.
Selecting the appropriate grinding wheel bond requires comprehensive consideration of the workpiece to be processed, the grinding machine equipment, dressing conditions and grinding requirements. Different binders have a significant impact on the grinding effect. Moresuperhard provides diamond grinding wheels with a variety of binders and formulas to meet the different grinding needs of customers.Despite the challenges associated with grinding cermet materials, machining efficiency and product quality can be significantly improved through proper selection of grinding wheels and bonding agents. If you need more advice or help, please feel free to contact us, Moresuperhard will be happy to serve you.
During the production process of ceramic diamond grinding wheels, raw materials such as diamonds and binders need to strictly control humidity and temperature. Excessive humidity may cause raw materials to absorb moisture, affecting the bonding strength and hardness of the grinding wheel; while excessive temperature may cause volatilization or unstable quality of certain materials, thus affecting the overall performance of the grinding wheel.
Single crystal diamond cutting tools are high-performance tools made from single crystal diamond, known for their exceptional hardness, wear resistance, and thermal conductivity.Effective grinding methods include using diamond grinding wheels, laser grinding, and mechanical grinding with cast iron or steel discs, each with its own advantages and requirements. Moresuperhard offers various solutions and consumables for grinding single crystal diamond tools, ensuring efficient production and high-quality results.
