Description

Technical Field

[0001] This utility model relates to the field of silicon nitride ceramic processing technology, specifically a cutting machine for silicon nitride ceramics. Background Technology

[0002] Silicon nitride ceramics are inorganic ceramic materials that do not shrink during sintering. Silicon nitride has very high strength, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It possesses properties such as high strength, low density, and high temperature resistance. During the processing of silicon nitride ceramics, a cutting device is typically required to cut them.

[0003] Existing cutting equipment typically uses a cutting saw blade to cut silicon nitride ceramics. When cutting silicon nitride ceramics, water needs to be poured on while cutting, and the wastewater generated during cutting can easily splash everywhere. The ceramic dust left on the surface of the cutting table requires workers to spend time cleaning, which increases the workload of workers and reduces the efficiency of silicon nitride ceramic cutting.

[0004] According to announcement number CN221496634U, a silicon carbide ceramic pipe cutting device is disclosed, relating to the field of cutting equipment technology. It addresses the technical problem of inconvenient clamping and fixing. The device includes a cutting table, with a mounting frame fixedly installed on its top. A first electric telescopic rod is fixedly installed on the mounting frame near the cutting table. A cutting blade is fixedly installed on the end of the first electric telescopic rod near the cutting table. A placement groove is provided on the side of the cutting table near the cutting blade. A clamping assembly is provided on the cutting table, including a clamping plate. Moving grooves are provided on both sides of one end of the cutting table, with a slider slidably installed in the moving groove. A mounting frame is fixedly installed on the side of the slider away from the cutting table. A telescopic rod, a spring, and a second electric telescopic rod are fixedly installed on the side of the mounting frame near the placement groove. This facilitates clamping operations, improves the device's clamping capacity, and enhances its adjustability.

[0005] According to the silicon carbide ceramic pipe cutting device described above, the wastewater generated during cutting is prone to splashing everywhere, and the ceramic dust left on the surface of the cutting table requires workers to spend time cleaning it, which increases the workload of workers and reduces the efficiency of silicon nitride ceramic cutting. Therefore, we need to propose a silicon nitride ceramic cutting machine. Utility Model Content
