Pallet vise

Cluster-lock [TM] is designed with multiple vising stations on a rigid pallet base. It increases small-part productivity by reducing the number of tool changes per part and shortening spindle travel between parts.

Cluster-lock is suitable for precision machining complete families of parts and components requiring one or more machining sequences. Parts can be set up in vise-holding stations in a consecutive pattern to allow progressive machining on all sides.

Designed for high-accuracy part holding, Cluster-lock incorporates the original Anglock principle, ensuring zero part lift and near-zero deflection during clamping operations. All Cluster-lock surfaces are accurate to 0.0001 ipi, and the pallet-base way-surface to 0.001" total.

Four products recently introduced by Hytec will be among the hydraulic workholding equipment to be displayed. A hydraulic work support designed for manifold mounting, eliminates external fittings and hoses to keep fixtures clean and easier to service. With a capacity of 2100 lb, the spring-loaded support is hydraulically connected through its bottom bushing, which seats leakfree in a port in the fixture.

Two hydraulic clamps can be converted from a right-to left-hand swing of 90 deg or to a straight pull. The threaded-body units contain integral metering valves so they can be used with any pump at any flow rate, and without being damaged from a sudden release of pressure stored in piping.

An air/hydraulic pump is designed for use with manual pallet valves. Equipped with a treadle for handsfree operation, it performs with air pressure of 40 to 125 psi to deliver hydraulic pressures of 1560 to 4875 psi.

A new system remotely monitors hydraulic clamping pressure on palletized machining centers via infrared light. It consists of a control unit, receiver, transponder, battery pack, and pressure switch--along with visual and audio alarms. The firm offers a CAD Graphics Library which simplifies the design of machining fixtures by eliminating the need to create graphic geometry.

Magnets hold 200 lb

Magnetic assemblies provide holding forces up to 200 lb and are suitable for fixtures, latches, controls, panels, and other part-holding applications. Often they eliminate the need for mechanical clamps and latches. Ceramic holding assemblies resist demagnetization by vibration and electrical fields and can be mounted directly in steel with no insulation. Alnico magnetic assemblies are also available for high-temperature applications up to 800 F.

Index tables

Three index-table variations will demonstrate PDC's adaptation of the Geneva-motion principle. Transparent dial plates allow full view of the tables' various mechanisms. The JIC-3A eight-station model mounts both vertically and horizontally, and includes a skip-station feature that converts the table to a four- or two-station unit on demand.

These Geneva index tables can serve a wide range of applications, including rotary assembly systems, drilling and tapping, robotics, and transfer tasks.

Adapting fixtures

Part distortion, normally associated with conventional clamp fixturing, is eliminated with the SAFE (Self Adapting Fixturing Elements) System. It's a system of supports and clamping points using a special flattened and hardened steel ball. Free to swivel within its socket, the self-aligning ball offers precision and distortion-free fixturing that's adaptable to any workpiece configuration.

Modular in design, the SAFE system includes horizontal and vertical adjustable support and clamping components that quickly mount on angles, base plates, and grid plates. Vertical and horizontal clamping units are available in either mechanical or hydraulic version, in both inch and metric sizes.
