Cutting Tool Slitting Tungsten Steel Blade Negative Rake Carbide Cutters
Negative rake carbide cutters are cutting tools commonly used in machining and metalworking applications.
These cutters virtually eliminate chipping and catches when turning resins, acrylic, and other man-made materials.
Excellent results when turning very hard woods, and very smooth finishing cuts.
Very effective for hollowing, allows for smooth catch-free passes.
| 1 | Design: | Negative rake cutters have cutting edges that are angled downward or away from the workpiece at a negative angle (typically less than 0 degrees). This design reduces the cutting angle and makes the tool more aggressive. |
| 2 | Material: | Negative rake carbide cutters have tips or inserts made of carbide, a hard and durable material that is well-suited for cutting tough materials like metal. |
| 3 | Applications: | Metalworking: Negative rake carbide cutters are often used in metalworking operations such as turning, milling, and boring.
Hard Materials: They are particularly effective for cutting hard materials like stainless steel, cast iron, and exotic alloys. |
| 4 | Advantages: | Increased Strength: The negative rake angle provides more support to the cutting edge, increasing tool strength and reducing the risk of chipping or breakage.
Better Surface Finish: Negative rake cutters can produce a smoother surface finish on the workpiece compared to positive rake cutters.
Higher Cutting Forces: The negative rake angle results in higher cutting forces, making these cutters suitable for heavy-duty machining applications. |
| 5 | Challenges: | Higher Cutting Forces: While the increased cutting forces can be advantageous for certain applications, they may also lead to higher power consumption and increased tool wear.
Heat Generation: Negative rake cutters can generate more heat during cutting due to the increased cutting forces, requiring proper cooling and lubrication. |
| 6 | Usage Tips: | Speed and Feed Rates: Adjust cutting speeds and feed rates according to the material being machined and the specific application.
Tool Angles: Ensure the negative rake angle is appropriate for the material and cutting conditions to optimize cutting performance.
Tool Maintenance: Regularly inspect and maintain the carbide inserts to ensure sharpness and cutting efficiency. |
Overall, negative rake carbide cutters are valuable tools in metalworking applications, offering increased strength, improved surface finish, and the ability to effectively cut hard materials. Proper selection and use of these cutters can help enhance machining performance and productivity.
Quality Control:
The production and processing of tungsten carbide, an important hard alloy material used in the manufacturing of cutting tools, drill bits, and abrasive tools, involve several steps. Here is a general outline of the tungsten carbide production and processing workflow:
- Raw Material Selection: Choose high-purity tungsten powder and carbon powder as raw materials to ensure the produced tungsten carbide exhibits excellent properties.
- Material Mixing: Blend the selected tungsten and carbon powders in specific proportions to form a uniform mixture.
- Pressing: Place the mixture into molds and subject it to high pressure to achieve the desired shape.
- Initial Sintering: Place the pressed blank in a high-temperature furnace for initial sintering, forming a preliminary structure.
- Powder Metallurgy Sintering: Subject the preliminarily sintered blank to powder metallurgy sintering, utilizing high temperature and pressure to facilitate the complete reaction between carbon and tungsten, resulting in tungsten carbide.
- Heat Treatment: Conduct heat treatment on the sintered product to adjust its crystal structure and properties, enhancing hardness and wear resistance.
- Product Machining: Process the heat-treated blank through cutting, grinding, and other machining techniques to produce the final tungsten carbide products.
- Surface Treatment: Optionally perform surface treatments such as coating or polishing to improve surface properties as needed.
- Quality Inspection: Conduct quality checks on the finished tungsten carbide products to ensure they meet specified technical standards and customer requirements.
Each step in this process requires precise control to ensure the final product possesses the desired physical and chemical properties. While variations may exist among different manufacturers and products, this serves as a general overview of the tungsten carbide production and processing workflow.
