Greenleaf's Excelerator Available in Coarse and Fine Pitch Designs
Westec 2019: Greenleaf’s Excelerator end and face mills are designed for high-performance milling in difficult-to-machine materials using either carbide or ceramic inserts in the same cutter bodies.
Greenleaf’s Excelerator end and face mills are designed for high-performance milling in difficult-to-machine materials using either carbide or ceramic inserts in the same cutter bodies. The milling cutters are available in both coarse and fine pitch designs.
According to the company, the fine-pitch mills are said to allow for higher productivity, increased speed and feeds, higher material removal rates, and better process stability with through air/coolant. The increased number of teeth over the coarse-pitch mills, combined with insert grades, is said to maximize efficiency.
The fine-pitch mills perform well in roughing applications that require more tooling stability. Having more teeth in the cut reduces the chance of vibration when machining forgings with heavy interruptions. Better engagement provided by the increased number of teeth also produces better surface finish than coarse-pitch milling cutters.
Greenleaf’s fine-pitch Excelerator end mills are available in diameters ranging from 3/8" to 2 ½" (10 to 63 mm). The fine-pitch face mills are available in diameters ranging from 3" to 12" (80 to 315 mm).
The right choices in tooling and technique can optimize the thread turning process.
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.
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.
