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.
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.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
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.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
