In a joint research project, Kaiser Precision Tooling and Blaser Swisslube searched for the combination of metalworking fluid and indexable insert that showed the best results when boring titanium. The results underscore the importance of controlling vibration, friction and heat.

The companies tested five metalworking fluids and several indexable insert grades from competing suppliers. All of the inserts tested were recommended for titanium applications. Findings showed that certain inserts lasted 15 times longer than others, depending on the choice of metalworking fluid. With the same metalworking fluid, certain inserts lasted 20 times longer than others.

Overall, the best combination for boring titanium proved to be the Kaiser 655.389 insert (TC11, AlCrN coating, 0.016-inch nose radius) with Blaser’s B-Cool 755 coolant.

  • Rigid Tapping--Sometimes You Need A Little Float

    One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.

  • Rolling Threads Has Advantages

    With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
