some unusual processing strategies, so it caught the attention of an outside-the-box thinker like Madariaga. The ICON 6-250 machine can handle parts up to 250-mm cube and is designed for medium to high-volume, flexible part production. The single machine incorporates eight individually controlled three-axis spindle modules, four horizontal and four vertical, with a full fourth-axis interpolation indexer at each of the four machining positions.
Spindles are arranged in pairs of one horizontal and one vertical at the four machining positions, which are on the perimeter of the six position pallet-transfer. The four machining positions are equipped with CNC B-axis indexers capable of ±4 arc-sec accuracy, while the two nonmachining stations are fixed position, one to be used for part loading and the other used for gaging, assembly, part ID marking, etc. Both nonmachining stations can also be used simply for part loading. A cycle for the pallet-transfer takes just 4.5
seconds, with each pallet handling up to 91 kg standard. The pallet system uses zero-point clamping to securely and ac- curately clamp the 300-mm base pal- let to the indexer.

Project Director Juan Ramon Delfin Madariaga studied technology from around the world before settling on an entirely different concept—the ICON 6-250 from Hydro- mat—to machine brass faucet components for leading plumbing fixture manufacturer, URREA Group.
Each HSK A63 spindle has its own 12-position disk-style toolchanger unit, with each tool change done in a rapid 3.5 seconds. A fully equipped ICON with eight ma- chining units has a total inventory of up to 96 tools. The disk allows direct toolchange without a cam box or toolchange arm, eliminating frequent maintenance issues. The machine can put up to eight spindles into the cut at one time, performing five-sided machining on four different parts at one time, all in a single clamping. Flex- ibility is enhanced with Fanuc standard programming, standard or special tooling, and fixturing typical of any horizontal/vertical machining center. The machine is completely self-contained with coolant system, hydraulics, PLC and CNC electrical systems—the equivalent of eight CNC machining centers in a footprint of just 54 m2
. For URREA’s first part numbers, two brass faucet spouts, Hydromat developed a
four-position tombstone-like fixture with hydraulic clamping and interchangeable form jaws. The form of the upper jaw provides the locating point for the part, so it is protected during loading from chips/contaminants. With this process concept, four parts are completed on every table index, with 20 parts in the workzone at all times. Operations on the parts include drilling, thread milling, tapping, counterboring, face milling, and chamfering. Each of the four machining stations performs different operations, further enhancing the machine’s output rate.
