Reciprocating Head Changes Tube Profiles
If you want to make an extruded plastic tube with two different interior profile geometries, typically you’ll have to extrude a section with one profile, do another run for the second profile, then attach the two with a connector. The Guill Tool & Engineering reciprocating head changes all that. Its design replaces a traditional tip and die assembly with a linear reciprocating assembly that can change the tube’s profile within a given length during extrusion. The process is repeated as needed throughout a single extrusion run without interruptions, and the finished product is cut to length. The technology improves product quality and eliminates the need for a second extrusion run, an assembly operation, and in-process inventory. It enables just-in-time manufacturing and faster throughput.

Twelve-station Rotary Transfer Machine
The Eclipse 12-100 is a 12-station rotary transfer machine that enables the complete production of parts from bar stock, castings, forgings or blanks with no need for secondary operations on another machine. In the bar-fed collet configuration, the machine has a maximum workpiece diameter of 65 mm, a maximum workpiece length of 180 mm, with 127 mm of material outside the collet. The machine has both 3- and 4-axis modules, with the former featuring strokes of 250 mm Z, 80 mm X and 100 Y and an 8,000- or 12,000 rpm FANUC direct drive servo motor; the latter strokes of 250 mm Z, 80 mm X (1), and 100 mm Y-axis, with the fourth axis a 30 mm X (2) axis stroke on the dynamic tooling head; there is a FANUC servo motor, as well. Table indexing is performed in 0.9 seconds. With a robotic load/unload at the first station and simultaneous machining on the other 11 stations, the machine is suitable for medium-to-high production. The one-piece, heavy-duty cast-iron machine base is a beefy 2 m in diameter, which contributes to vibration dampening.

Drills Optimized for Aluminum
The CoroDrill 400 and CoroDrill 430 are both designed for machining of aluminum components in medium-to-high volumes. The company recommends CoroDrill 400 for drilling into solid material, as it features more flute volume for better chip evacuation. CoroDrill 430 is preferable for drilling into cored material or pre-cast holes, as it features three flutes for stability and holding position regardless of misaligned cored holes. The drills are both available in N1BU solid-carbide grade, recommended for when the hole count is low and handling risk is high. CoroDrill 430 is also available in the N1DU polycrystalline diamond (PCD) grade, which is preferable when the hole count is high and higher productivity is required. Both models feature polished flutes and precision coolant holes, with support provided for MQL (minimum quantity lubrication) systems. The solid drills in the lineup are available in sizes to cut diameters from 5 to 12.5 mm.

High-precision Abrasive Waterjet
The Finecut WMC 500 II micro-abrasive waterjet system can cut complex shapes out of virtually all materials with neither thermal nor mechanical damage—but in this case, the dimensions of those shapes can be very small. The system has a positioning accuracy of ± 2.5 µm and is capable of jet diameters down to 200 µm. It can be used to cut high-precision features into parts up to 19.7 × 19.7 inches in size. While the thickness is material-dependent, up to 30 mm is said to be generally acceptable. The machine is a good complement to wire-EDMs, according to the company. It offers the advantage of no recast layers and the ability to do piercing and cutting in one setup. Unlike traditional waterjet systems, the machine is completely enclosed, enabling it to be placed anywhere in a work area.

Design, materials, powertrain and manufacturing details about what is arguably the quintessential vehicle in the Jeep lineup.
Plenty of interior components are injection molded. But some companies—such as VW—are using a process for trim pieces that both mold a component and cover it in fabric in a single molding process. And it is coming to the U.S. in the not-too-distant future.
