When Four Spindles Make Sense
Now envision a lathe that has four spindles positioned in a square formation on an indexing carrier drum. The carrier drum functions in much the same way as an HMC’s pallet changer. It locates two of the four spindles within the lathe’s enclosed machining environment to allow turning of two workpieces. Meanwhile, the two spindles positioned outside the machining zone can be loaded manually or via robot or gantry

Creep-feed Grinding Is A Milling Process (So Why Not Use A Vertical Machining Center?)
Creep-feed grinding is an abrasive machining process, but beyond that, it doesn’t resemble other forms of grinding. Nelson Beaulieu, grinding product manager with Hardinge Inc., says it makes more sense to characterize creep-feed grinding as a milling process.
After all, creep-feed grinding employs a deep cut and a high metal removal rate, and it features a low feed rate in place of fast reciprocating motion. The “tool” in creep-feed grinding—the grinding wheel—gets buried in the material like a milling cutter.

Integral, Thermal Chucks with Standard Taper Adaptation
The integral SRKIN SHRINKIN toolholder line was designed for milling applications requiring higher rigidity - the new generation of integral SRKIN toolholders.
These new toolholders actually integrate the SHRINKIN ER SRK... collets with standard taper shanks to form a single, solid piece toolholder. These integral units may be used for solid carbide, steel and HSS shanks.

Meeting the Demands of Multi-Tasking: CAM and Machine Simulation
Multi-task machining (MTM) class machine tools—also sometimes referred to as multi-flow machine tools—are an excellent example of technology rising to meet the competitive challenge. MTM machine tools offer the user a unique system configuration, which allows the part to be accessed from all sides without having to be manually refixtured; the machine exchanges the part between spindles reorienting the part and allowing the tooling to cut in areas previously inaccessible.

Atomic-Level Engineering For Greater Tool Life
Thickness, purity, structural integrity, smoothness and chemical composition are among the variables that cutting tool developers can manipulate to engineer and improve cutting tool coatings.
Don Graham, turning products manager with Seco Tools, says that now there is a new variable: crystal orientation.

RAMTIC System Still Ticking
Renishaw, a U.K.-based maker of metrology systems, developed RAMTIC, its unique approach to process control, in the early 1990s. When it first appeared, RAMTIC (Renishaw’s Automated Milling, Turning and Inspection Center) was characterized by two conspicuous developments in tangible machine tool technology. One was the use of portable carrousels for palletized workpieces and cutting tools. The other was the use of artifacts, or master components, by which a machine tool could check its own dimensional calibration.
