1. Product Overview


CNC Milling Half Dies are indispensable tools in modern manufacturing, especially in industries such as automotive, aerospace, and consumer electronics. These dies are designed to create complex and precise components through the milling process. Their half - die design allows for flexibility in production, enabling the creation of a wide range of shapes and sizes.

2. Product Materials

High - Quality Tool Steel


Commonly used tool steels like D2, H13, and A2 are prime choices for CNC Milling Half Dies. D2 steel offers excellent wear resistance and high hardness, making it suitable for long - run production where the die is subjected to repeated cutting forces. H13 steel is known for its good thermal fatigue resistance and toughness, which is crucial when the die experiences high temperatures during the milling process. A2 steel provides a balance between hardness and machinability, making it a versatile option for various applications.

Carbide Inserts


In some cases, carbide inserts are incorporated into the dies. Tungsten carbide inserts are extremely hard and wear - resistant, capable of withstanding high - speed cutting operations. They are often used in areas of the die that require precise cutting and extended tool life, such as the cutting edges for intricate features.

3. Product Processing Process

Design Phase


  • CAD Modeling: Our engineering team uses advanced Computer - Aided Design (CAD) software to create a detailed 3D model of the CNC Milling Half Die. This model takes into account the specific requirements of the end - product, including dimensions, tolerances, and surface finish.

  • Simulation: Before production, the design is simulated to ensure that the milling process will be efficient and error - free. This helps to identify any potential issues and optimize the design for better performance.

Material Preparation


  • Cutting: The selected tool steel or other materials are cut to the appropriate size and shape according to the design specifications. This may involve sawing, shearing, or other cutting methods.

  • Heat Treatment: The cut materials undergo heat treatment processes such as quenching and tempering. Heat treatment enhances the hardness, toughness, and wear resistance of the material, ensuring the die can withstand the rigors of the milling process.

CNC Milling


  • Programming: A Computer - Aided Manufacturing (CAM) system is used to generate the CNC milling program. This program controls the movement of the milling machine, specifying the cutting paths, feed rates, and spindle speeds.

  • Milling Operations: The CNC milling machine uses a variety of cutting tools, such as end mills, ball mills, and drills, to remove material from the workpiece and create the desired shape of the half - die. Multiple passes may be required to achieve the required precision and surface finish.

Finishing


  • Grinding and Polishing: After the milling process, the die is ground and polished to achieve the final dimensional accuracy and surface smoothness. This step is crucial for ensuring that the die produces high - quality components.

  • Inspection: The finished die is inspected using precision measuring instruments such as coordinate measuring machines (CMMs) to ensure that it meets the specified tolerances and quality standards.

4. Product Usage Precautions

Installation


  • Proper Alignment: When installing the CNC Milling Half Die on the milling machine, ensure that it is properly aligned. Misalignment can lead to inaccurate cutting and premature wear of the die.

  • Secure Mounting: The die must be securely mounted to the machine table or fixture to prevent any movement during the milling process. Loose mounting can cause vibrations, which can affect the quality of the machined parts.

Operation


  • Operating Parameters: Follow the recommended operating parameters, such as spindle speed, feed rate, and depth of cut. Deviating from these parameters can result in poor surface finish, excessive tool wear, or even damage to the die.

  • Coolant and Lubrication: Use appropriate coolant and lubrication during the milling process. Coolant helps to reduce heat generated during cutting, which can extend the life of the die and improve the quality of the machined surface. Lubrication reduces friction between the cutting tool and the die, further enhancing performance.

Maintenance


  • Regular Cleaning: After each use, clean the die thoroughly to remove any chips, debris, or coolant residue. This helps to prevent corrosion and maintain the accuracy of the die.

  • Inspection and Replacement: Regularly inspect the die for signs of wear, damage, or cracks. Replace any worn - out parts or damaged dies promptly to ensure the continued quality of production.


In conclusion, CNC Milling Half Dies are high - precision tools that offer great flexibility and efficiency in manufacturing. By understanding the materials, processing, and usage precautions, users can maximize the performance and lifespan of these dies.
