Tool Steel: High-grade tool steel is a primary material for many of our cutting tools. It offers excellent hardness, wear resistance, and toughness. Elements like chromium, tungsten, and vanadium are alloyed in the steel to enhance its performance. Chromium improves corrosion resistance, tungsten increases the steel's hardness and wear resistance at high temperatures, and vanadium helps in forming fine carbide particles, further enhancing the tool's cutting ability.
Carbide: For more demanding cutting applications, carbide materials are used. Tungsten carbide, in particular, is extremely hard and wear-resistant, making it suitable for cutting tough materials in household appliance manufacturing, such as metal housings or frames. Carbide tools can maintain their sharp edges for longer periods compared to traditional tool steel tools.
Polishing Abrasives: In the case of polishing tools, various abrasives are employed. Aluminum oxide and silicon carbide abrasives are commonly used. Aluminum oxide abrasives are suitable for general-purpose polishing of metals and plastics, providing a smooth finish. Silicon carbide abrasives, on the other hand, are harder and more aggressive, ideal for removing stubborn scratches or rough surfaces on materials like stainless steel or ceramic components of household appliances.
Bonding Materials: To hold the abrasives in place for polishing tools or to attach carbide inserts to cutting tools, bonding materials such as resin or metal bonds are used. Resin bonds are often used for softer abrasives and provide a more flexible and conformable polishing surface, while metal bonds are stronger and better suited for holding hard carbide inserts in cutting tools.
Design and Customization: Based on the specific requirements of household appliance manufacturers, our engineering team uses advanced CAD/CAM software to design the tools. This includes determining the shape, size, and cutting or polishing geometry of the tools to ensure they can perform optimally on the target components.
Material Preparation: Select the appropriate materials according to the design. For cutting tools made of tool steel, the steel is first cut to the approximate size and then heat-treated to improve its mechanical properties. Carbide materials are often pre-shaped and sintered to achieve the desired hardness and density. For polishing tools, the abrasives are sorted and graded according to their particle size, and the bonding materials are prepared in the appropriate form.
Machining and Assembly: For cutting tools, machining operations such as milling, turning, and grinding are carried out to shape the tool body and create the cutting edges. Carbide inserts are brazed or mechanically fastened to the tool body. In the case of polishing tools, the abrasives are bonded to the tool substrate using techniques like pressing or casting, depending on the type of bonding material.
Heat Treatment and Finishing: Cutting tools may undergo additional heat treatment processes, such as tempering, to relieve internal stresses and improve their toughness. Both cutting and polishing tools then go through a finishing process, where the surfaces are ground or polished to achieve the required dimensional accuracy and surface finish.
Quality Inspection: Each tool is thoroughly inspected using various measuring instruments, such as coordinate measuring machines (CMMs) for dimensional accuracy and microscopes for inspecting the cutting edges or abrasive surfaces. Only tools that meet our strict quality standards are allowed to leave the factory.
Tool Selection: Choose the appropriate polishing or cutting tool based on the material and processing requirements of the household appliance component. Using the wrong tool can lead to poor results, such as uneven polishing or damaged cutting edges.
Operating Speed and Pressure: Follow the recommended operating speed and pressure guidelines provided by the manufacturer. Excessive speed or pressure can cause the tool to overheat, wear out prematurely, or even break. For polishing tools, applying too much pressure can result in an uneven finish or damage to the surface being polished.
Cooling and Lubrication: When using cutting tools, ensure proper cooling and lubrication. Use appropriate cutting fluids to reduce friction, lower the temperature of the cutting area, and extend the life of the tool. For polishing tools, some may require the use of polishing compounds or lubricants to achieve the best results.
Tool Maintenance: Regularly inspect the tools for signs of wear, damage, or dullness. Sharpen or replace cutting tools when the cutting edges become dull, and replace polishing tools when the abrasives are worn out. Keep the tools clean and stored in a dry place to prevent rust or corrosion.
Safety Precautions: Always wear appropriate personal protective equipment (PPE), such as safety glasses, gloves, and masks, when using these tools. Follow all safety procedures and guidelines to prevent accidents and injuries.
