Look Ahead

Italy-based Samputensili S.p.A. unveiled a machine that eliminates the need for cutting oils when manufacturing gears, thereby reducing grinding costs. During grinding, oil-based lubricants cool the workpiece, as well as reduce friction and help evacuate chips. On the downside, however, oil use accounts for a significant amount of a grinding operation's total cost.

Researchers at North Carolina State University reported the discovery of a distinct form of solid carbon they estimate is about 10 percent harder than diamond and could play an important role in machining. They also claim to have developed a relatively inexpensive technique for producing the substance, called Q-carbon, at room temperature and ambient atmospheric pressure.

PCD oxidizes when cutting materials such as iron, cobalt, nickel, chromium and vanadium because of the high temperatures generated while cutting. Although not as hard, PCBN possesses superior chemical inertness compared to PCD.

KME CNC developed a 5-axis tombstone 8 years ago for horizontal machining centers that allows milling on five or more sides of a workpiece and on four different platters in a single setup. Recently, the company unveiled a version that requires no wires, cables or any type of connection, making it easier to move parts in and out of a machine.

Turbine blades are typically mounted on compressor disks and milled from a single piece of material rather than constructed blade by blade. These are known as blade-integrated disks, or blisks, and their main function is to compress air in the turbine.

To improve performance, reduce cycle times and enhance machine operation, Makino Inc. has released Hyper technologies for its full line of wire, sinker and holemaking EDMs.n
