As part of its multi-year Global Productivity Initiative, Greenleaf Corp. has announced the introduction of a new Silicon Nitride ceramic insert grade, GSN-100. GSN100 is an engineered blend of silicon nitride and proprietary toughening agents that redefine productivity in the machining of cast iron. Brake drums, brake rotors, cylinder blocks and heads, machine beds, all types of gear cases and housings for trucks, tractors and farm equipment are a few of the popular parts where GSN100 will dramatically increase productivity.
"GSN100 delivers outstanding tool life at cutting speeds of up to 5000 SFPM (1525 M/Min) in single point turning and grooving operations as well as milling," states David Rydbom, Greenleaf's Vice President of Sales and Marketing. "GSN100 is available in standard and special geometries, trigons, Rough Stuff surface treatments and custom edge preparations for specific applications."
Greenleaf's Global Productivity Initiative is a multi-year campaign to provide unique, highly productive tooling solutions and services to Greenleaf's global customer base. The initiative includes new products, increased investment in production capabilities and the development of a larger, better-trained technical field service team.

gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
