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.

  • 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.

  • Drill And Bore With A Face Mill

    Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.

  • Taking The Fear Out Of Hard Turning

    To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
