- Tool Failure: Identifying the point when the tool becomes unusable or ineffective.
- Surface Finish: Evaluating the quality and smoothness of machined surfaces.
By considering these factors, machinists can optimize tool usage, prolonging tool life and minimizing production interruptions.
Which steel is used for cutting tools
High-speed tool steel (HSS) is the popular choice for cutting tools due to its excellent balance of hardness, toughness, and durability. The composition of HSS typically includes elements such as tungsten, molybdenum, and vanadium, enabling these tools to handle a wide range of machining operations. So, when it comes to cutting tools, HSS is definitely a cut above the rest!
How are carbides classified
Carbides are classified based on their composition and grade. Here are the three common classifications:
- Cemented Carbides: Combining carbide particles with a binder, usually cobalt. The most popular is tungsten carbide-cobalt (WC-Co).
- Coated Carbides: Carbide substrates with a thin coating of materials like titanium nitride (TiN) or titanium carbonitride (TiCN). These coatings enhance surface hardness, reducing wear and friction.
- Cermets: Composed of a ceramic rich phase, usually titanium carbide (TiC), and a metallic binder. Cermets provide excellent cutting performance at elevated temperatures.
These carbide classifications ensure that cutting tools are tailored to withstand the challenges of different machining operations.
Now that you have all the cutting tool knowledge at your disposal, go forth and conquer the machining world with your newfound expertise! Remember, whether it’s single-point cutting tools, carbides, or the mighty CBN, there’s a cutting tool for every job. Happy machining!
