In the metal processing industry, the hardware meat grinder disc is a key component of food processing machinery, and its exquisite processing procedures directly affect the efficiency, safety, and final product quality of food processing. The hardware meat cutter disc is usually made of corrosion-resistant and high-strength materials such as stainless steel. Its complex structural design and precise processing requirements make the entire production process full of challenges and technical content. Below, we will delve into the complete processing steps of the hardware meat cutter from raw material preparation to finished product inspection.

1、 Raw material selection and inspection

The preferred raw material for the hardware meat cutter disc is food grade stainless steel, such as 304 or 316 stainless steel. These materials not only have good corrosion resistance, but also maintain stable mechanical properties in food processing environments. After the arrival of raw materials, strict chemical composition analysis, hardness testing, and appearance inspection are required to ensure the absence of defects such as cracks and inclusions, laying a solid foundation for subsequent processing.

2、 Cutting and rough machining

After strict screening, the raw materials enter the cutting stage. Using a high-precision CNC cutting machine, accurately cut the basic shape of the cutterhead according to the design drawings. This process requires extremely high dimensional accuracy and flatness of the cutting surface to ensure smooth subsequent processing. Subsequently, rough machining is carried out, mainly including deburring, chamfering and other treatments, to create favorable conditions for subsequent precision machining.

3、 Precision machining

Precision machining is the core process of manufacturing hardware meat cutter discs, including multiple steps such as CNC milling, grinding, and drilling. Firstly, contour machining is performed on the cutter head using a CNC milling machine to precisely control the tool path, ensuring that the shape, angle, and distribution of each tooth are uniform and consistent. Subsequently, high-precision grinding machines are used to finely grind the cutting teeth to achieve the required sharpness and surface smoothness. At the same time, it is necessary to drill installation holes, positioning holes, etc. on the cutter head to ensure that the cutter head can be stably installed on the machine.

4、 Heat treatment and surface treatment

In order to improve the hardness and wear resistance of the hardware meat cutter disc, heat treatment is usually required. By heating to a certain temperature and rapidly cooling (such as quenching), the internal structure of the material changes, thereby improving its mechanical properties. After heat treatment, tempering treatment is also required to eliminate internal stress and maintain the stability and toughness of the material. In addition, in order to prevent rusting of the cutterhead during use, surface treatment such as electrolytic polishing, sandblasting, or chemical passivation is also required to enhance its corrosion resistance.

5、 Dynamic balance test

When the hardware meat grinder rotates at high speed, if there is an imbalance, it will produce huge vibration and noise, seriously affecting the stability and service life of the machine. Therefore, a strict dynamic balance test must be conducted on the cutterhead before assembly. This step is usually carried out using high-precision dynamic balancing machines, by adding or removing small masses at different positions of the cutterhead until the specified dynamic balancing accuracy requirements are met. Dynamic balance testing not only ensures the stability of the cutterhead during high-speed rotation, but also reduces mechanical wear and energy loss caused by vibration, thereby improving overall machining efficiency and product quality.

6、 Assembly and Debugging

The hardware meat cutter disc that has undergone all the above processes will enter the assembly stage. In the dust-free workshop, technicians will strictly follow the process flow to accurately assemble the cutterhead with components such as bearings and seals. During the assembly process, special attention should be paid to the fitting accuracy and fastening torque between each component to ensure the stability and reliability of the cutterhead during operation. After assembly, the entire machine needs to be debugged, including rotation testing, noise detection, and performance evaluation, to ensure that the cutterhead can work smoothly and efficiently.

7、 Finished product inspection and packaging

Finally, the hardware meat grinder must undergo strict finished product inspection. The inspection items include but are not limited to dimensional accuracy, surface quality, dynamic balance performance, corrosion resistance, and mechanical strength. Only cutting discs that fully meet the design requirements and quality standards can be judged as qualified products. After passing the inspection, the cutterhead will be properly packaged to prevent damage during transportation and storage, and detailed product manuals and warranty cards will be attached to provide customers with comprehensive after-sales service support.

Through this series of complex and delicate processing procedures, the hardware meat cutter not only possesses excellent processing performance and durability, but also becomes an indispensable and important component in the food processing industry, making significant contributions to improving the efficiency and quality of food processing.
