Four-Spindle Technology Drives ProductivityAvailable from SB Machine Tools, Kitako's new generation, four-spindle CNC (Computerized Numerical Control) See numerical control.CNC - Collaborative Networked Communication lathe-the HS4200Ì with ultra-high-speed automated gantry Gantry A name for the couch or table used in a CT scan. The patient lies on the gantry while it slides into the x-ray scanner portion. Mentioned in: Computed Tomography Scans loader-boasts X-axis gantry-loading feed rates of 6700 ipm. Combined, the HS4200i's four-spindle operation and gantry-loading capability accomplish smooth, untended operation with no idle time The duration of time a device is in an idle state, which means that it is operational, but not being used. for part loading/unloading. Extremely fast rapid traverse rates, along with carrier indexing time of 1.5 sec (0.3 sec turret indexing per station) provide a quantum jump quantum jump n. 1. Abrupt change from one energy level to another, especially such a change in the orbit of an electron with the loss or gain of a quantum of energy. 2. A quantum leap. in productivity. Kitako's unique four-spindle technology provides a seamless cycling of work from the loading zone Noun 1. loading zone - a stop where carriers can be loaded and unloaded loading area stop - a spot where something halts or pauses; "his next stop is Atlanta" to the machining zone and back again. Operating much like a pallet changer Changer The name given to a clearing member that is willing to assume the opposite position of a futures contract within a larger alternative exchange, of which it also is a clearing member. on a machining center, the system transitions parts in and out of the machining zone in as little as 0.8 sec each. The HS4200i's four spindles are mounted in a horizontal, square pattern in a large carrier drum. The drum's positioning accuracy is ensured by a largediameter, precision-toothed, curvic coupling. Spindles are generally partnered as pairs, so as the carrier is indexed 180° two spindles rotate to the machining area as two spindles move out for loading and unloading. The two spindles in the machining zone, along with the respective slides and turrets, work simultaneously as well as independently. This dual-slide flexibility offers a variety of part- processing meth- ods, including: two one-sided parts can be machined in exactly the same time (referred to as an AA/AA operation); if the two sides of a part are of near equal cycle times, first and second operations can be done simultaneously ( AB/AB); if the first and second cycles are significantly different, as in many applications, idle time can be eliminated by using an AA/BB approach. The main spindles of the HS4200Ì are hardened, precision-ground, and supported by accurate doublerow cylindrical roller bearings and angular-contact bearings. The cartridge-type spindles are sealed for life, and require no maintenance. Box slide-ways on both the X-axis and the Z-axis can achieve high chipremoval rates. The HS4200i's maximum spindle speed is 4500 rpm (5000 rpm optional). Each slide on the HS4200Ì features a high-speed eight-station drum turret; chuck size is 8 " .
