The company introduces the Radicator, an inserted carbide back draft milling cutter. The design of the new insert has moved the actual cutting edges closer to center, allowing a much freer cut, the company says. The massive size of the insert is said to promote improved heat dissipation. Applications include semi-rough, semi-finish and finish profile milling, along with other uses.
The 1" diameter tool holder is available in 6-, 8-, 10- and 12-inch lengths. Two types of inserts are offered, including a double-sided version for profile work or tapered walls. A single-sided insert can be used for cutting straight walls.
The new inserts are offered with corner radii of 1/32, 1/16, 3/32, 1/8, 5/32, 3/16, 7/32 and 1/4. All inserts--TIALN coated or uncoated--are available off the shelf. Other diameters are anticipated for release.
To take advantage of a lull in business, JR Machine devised a week-long cutting tool event that elevated the shop’s capabilities with aerospace alloys.
Tooling options have been limited for small spindle milling applications. Now modular, indexable systems are available that provide broad flexibility to get the right cutter for the job with less inventory and at lower cost.
