What Cutting Parameters Should Be Used with Tungaloy Inserts
When it comes to machining operations, selecting the right cutting parameters is crucial for achieving optimal performance and extending tool life. Tungaloy inserts are known for their high quality and versatility, making them a popular choice among manufacturers. However, ensuring that the correct cutting parameters are used is essential for maximizing the benefits of these inserts. This article will outline key cutting parameters to consider when using Tungaloy inserts.
1. Cutting Speed (Vc): The cutting speed is one of the most important parameters in machining. For Tungaloy inserts, the recommended cutting speed depends on the material being machined, the type of insert, and the application. For example, when machining steel with Tungaloy's carbide inserts, a cutting speed range of 80-250 m/min is often recommended. Always refer to the manufacturer's guidelines to select the optimal speed for specific applications.
2. Feed Rate (f): The feed rate directly affects the chip formation and the surface finish of the machined part. Tungaloy inserts are designed to handle various feed rates, which can range from 0.1 mm/rev to 0.5 mm/rev for roughing operations. For finishing operations, a lower feed rate is typically recommended, around 0.05 mm/rev to 0.1 mm/rev, to achieve a superior surface finish. Adjusting the feed rate according to the insert's chip thickness requirements will help in maintaining tool integrity.
3. Depth of Cut (ap): The depth of cut impacts tool durability and the final part dimensions. Tungaloy inserts can manage different depths of cut depending on the insert geometry and the stability of the machining setup. A shallow depth of cut is often preferred for finishing operations (typically around 0.2 mm to 1 mm), while a more aggressive cut can be used during roughing (up to 3-5 mm), depending on the rigidity of the machine and workpiece.
4. Coolant Usage: Utilizing coolant or cutting fluids is essential to reduce heat buildup during machining and improve tool life. Tungaloy offers several inserts that are optimized for both wet and dry machining environments. When using coolant, ensure that it is applied properly to facilitate better chip removal and reduce friction on the insert cutting edges.
5. Tool Holder and Rigidity: The choice of tool holder and the overall rigidity of the setup play a significant role in machining performance. Ensure that the tool holder is compatible with Tungaloy inserts and is designed to minimize vibration during machining. A stable setup will allow for optimal cutting parameters to be realized, leading to improved surface finish and tool life.
In conclusion, utilizing Tungaloy inserts efficiently requires careful consideration of cutting parameters such as cutting speed, feed rate, depth of cut, coolant usage, and the rigidity of the tool holder. By adhering to the manufacturer's recommendations and adapting the parameters based on specific applications, manufacturers can enhance performance and achieve high-quality machined parts. Always refer to Tungaloy’s technical guides for the most accurate recommendations tailored to your machining needs.
