High-Grade Die Steel: The primary material for the die body is high-quality die steel, such as D2 or H13. D2 die steel offers excellent wear resistance and high hardness after heat treatment, making it suitable for applications where the die needs to withstand repeated contact and friction during the polishing process. H13, on the other hand, is known for its good thermal fatigue resistance, high toughness, and hardness, which allows it to perform well even under high-temperature conditions that may occur during polishing operations.
Polishing Abrasive Materials: For the polishing segments, a variety of abrasive materials are used depending on the specific polishing needs. Common ones include diamond abrasives, which are extremely hard and ideal for achieving a fine surface finish on hard materials like carbide, ceramics, and hardened steels. Cubic boron nitride (CBN) abrasives are also utilized, especially for polishing ferrous materials, as they offer high wear resistance and can work effectively at high speeds. Additionally, aluminum oxide and silicon carbide abrasives may be used for less demanding polishing tasks or on softer materials.
Bonding Materials: To attach the polishing abrasive segments to the die body, high-strength bonding materials are employed. Resin bonds are often used for diamond and CBN abrasives in applications where a relatively flexible bond is required, allowing for better conformability to the workpiece surface. Metal bonds, on the other hand, provide a more rigid and durable attachment, suitable for applications where high pressure and heavy-duty polishing are involved.
Design and Customization: Based on the customer's specific requirements, including the shape, size, and surface finish requirements of the workpiece to be polished, our engineering team uses advanced CAD/CAM software to design the segmented die. The design takes into account factors such as the distribution of the polishing segments, the shape of the die body, and the overall mechanical structure to ensure optimal performance.
Die Body Machining: The die body is machined from the selected die steel using high-precision CNC machining centers. Operations such as milling, turning, and drilling are carried out to create the precise shape and features of the die body. Special attention is paid to the accuracy of the mounting surfaces for the polishing segments to ensure proper alignment.
Abrasive Segment Preparation: The polishing abrasive segments are prepared separately. For diamond and CBN abrasives, they are often sintered or bonded with the appropriate bonding material to form the desired shape and size of the segments. The segments are then carefully inspected for quality and uniformity of the abrasive distribution.
Assembly: The prepared polishing segments are precisely mounted onto the die body using the bonding materials. This process requires high precision to ensure that the segments are evenly distributed and properly aligned. Special fixtures and techniques may be used to ensure a secure and accurate attachment.
Heat Treatment and Finishing: After assembly, the die may undergo heat treatment to enhance the mechanical properties of the die body and the bond between the segments and the body. Following heat treatment, the die is finished by grinding and polishing the outer surface to achieve the required dimensional accuracy and surface finish.
Quality Inspection: The completed segmented die is thoroughly inspected using a variety of measuring instruments, such as coordinate measuring machines (CMMs), surface roughness testers, and optical microscopes. The inspection checks for dimensional accuracy, surface finish of the segments, and the integrity of the bond between the segments and the die body. Only dies that meet our strict quality standards are released for use.
Proper Installation: When installing the polishing segmented die in the polishing equipment, ensure that it is correctly aligned and securely fastened. Use the appropriate tools and follow the manufacturer's installation instructions to avoid any misalignment or loose connections that could affect the polishing performance.
Workpiece Compatibility: Ensure that the workpiece to be polished is compatible with the die. Consider factors such as the material hardness, shape, and size of the workpiece. Using the die on an incompatible workpiece may result in poor polishing results or damage to the die.
Operating Parameters: Follow the recommended operating parameters provided by the manufacturer, including the polishing speed, pressure, and feed rate. Excessive speed or pressure can cause the abrasive segments to wear out prematurely or even damage the workpiece surface. Adjust the parameters according to the specific requirements of the polishing task.
Lubrication and Cooling: Use appropriate lubricants and cooling agents during the polishing process to reduce friction and heat generation. This helps to prolong the life of the die and improve the quality of the polished surface. Ensure that the lubrication and cooling systems are functioning properly.
Inspection and Maintenance: Regularly inspect the die for signs of wear, damage, or loose segments. Check the surface finish of the segments and the overall performance of the die. If any issues are detected, take appropriate measures such as replacing worn segments or adjusting the operating parameters. Keep the die clean and store it in a suitable environment when not in use to prevent corrosion and damage.
