Tungaloy’s BallRoughNose Provides Reliability for Roughing, Semi-Finishing
Tungaloy’s BallRoughNose is designed to provide maximum tool reliability during roughing and semi-finishing processes. Its dovetail insert clamping design prevents the insert from being lifted by cutting forces during demanding operations, and a locking design in the insert seat helps prevent rotation. These features are said to boost insert reliability during 3D profiling or plunging processes, while the insert’s helical cutting edge helps to mitigate heavy cutting forces for lighter cutting action.
A hybrid design allows one side of the insert to be used for center cutting and the other for peripheral cutting. This eliminates the need to purchase two different types of inserts, reducing tool investment and inventory costs and simplifying management, the company says.
The tool body includes coolant channels for effective chip evacuation in order to keep chips from being recut during complex profiling of die and mold parts. The tool shanks are available in working diameters of 16, 20 and 25 mm (0.625", 0.75" and 1") and in an array of designs including cylindrical shanks with standard length or with long necks and modular styles.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
Economic efficiency is an important consideration when choosing tools for challenging metals.
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.
