Precision parts cleaning

The AVD 300 aqueous parts washer is for complex and intricate-machined or stamped parts that require very high standards of cleanliness, surface finish, and drying. This compact, fully-automatic, self-contained aqueous cleaning system removes all types of contamination including soluble and mineral oils or greases, polishing compounds, lapping paste, and NDT dye penetrants from sensitive alloys. The AVD is capable of cleaning large components or dense baskets of small parts, with a compact design that is well suited for small-volume, high-precision machining cells.

Sized for cell manufacturing or within a centralized layout, the AVD 300 measures 4ft x 8ft x 8ft, and features full-immersion, spray, and ultrasonic washes. The system also comes fitted with hot air dry as well as vacuum dry. The aqueous technology cleans without solvents or emissions.

2,000°F inert atmosphere

No. 954 is an electrically heated 2,000°F (1,093°C) inert atmosphere heavy-duty box furnace for heat-treating titanium. Supported by vacuum-formed ceramic fiber, 57kW of installed nickel-chrome wire coils heat the loads. Workspace dimensions are 30" x 48" x 30". The oven’s 7"-thick insulated walls are comprised of 5" of 2,300°F ceramic fiber and 2" of 1,700°F ceramic fiber, while the 6-1/2" floor insulation is comprised of 4-1/2" of 2,300°F firebrick and 2" of 1,200°F block insulation.

The unit is equipped with a roof-mounted heat-resisting alloy-recirculating fan powered by a 1hp motor with a V-belt drive; motor-operated vertical lift door; 100-lb capacity alloy loading cart with cast alloy roller rails; 3-1/2" diameter cast alloy rollers; and a roller rail-loading table with 4" diameter cast iron rollers.

Coolant thru tool clamp

The Multidec-Lube tool clamp system permits optimum coolant jet positioning and reduces setup time when employing high-pressure coolant delivery. Incorporating a coolant/oil delivery passage in the tool clamp, the design ensures a repeatable jet flow even after multiple tool changes, setups, or teardowns, and replaces the original equipment gang-slide tool clamps provided with Swiss machines. Since coolant travels through the clamp and can remain semi-permanently plumbed into the high-pressure system, conventional square shank toolholders can be used as if they were coolant-thru holders. The clamp is designed to allow for an easy fit into machines while also delivering rigidity. High repeatability is ensured by the fixed and adjustable stop that makes it possible to position the tools in exactly the same location following insert changes.

Benefits

• No chip collectionon coolant jet nozzles
• Elimination of stringy chip wrap-arounds or clogging
• Avoidance of accidental bending or repositioning of coolant tubes/nozzles during tool changes over machining cycles

Vise jaws system

VersaGrip allows versatility of clamping standard vise work as well as providing a solution for difficult applications that would normally require fixturing or machining soft-jaws. When using the VersaGrip system, machinists can securely hold odd-shaped parts while machining at higher speeds and feeds. The system can accommodate a wide range of part sizes as well as holding multiple parts in a single cycle. VersaGrip has penetrating teeth designed to bite into the workpiece to prevent lateral and horizontal movement.

VersaGrip specs

• Part #: 32175
• Dimensions: 0.750" x 0.375"
• Recommended gripping height: 0.060" to 0.140"

Micro TIG welder

The MAWA-300A micro TIG welder is a non-contact process and does not need force to create proper part fitup. The unit produces high quality welds with minimal heat-affected zones by generating arcs between the workpiece and the tungsten electrode, using the resultant heat to create the joint. Unlike resistance or ultrasonic welding, this method is capable of joining dissimilar metals.

Two key features of the MAWA-300A are pulsation and touch start. Pulsation allows the user to selectively turn the current on and off during the weld. The frequency can be up to 5kHz for very rapid firing. Touch start drives the electrode to contact the workpiece and then retract at a given speed. The electrode starts to fire in low current at a short distance from the part. This helps control the location of the weld and reduces electrical noise emitted in arc generation.

At-a-glance

• 3-phase unit
• Weight: 30kg FET-driven constant current control – weld time range is 0 to 2,000ms
• IGBT-driven constant current control – weld time range is 0 to 999ms

Flawless weld joints

A new version of the HiQ DIALOG series enables repeatable welds with low welding forces of 5N – beating the previous low-level maximum of 20N. The development of the low force answers the challenge of achieving repeatable welding results in precision parts.

It is possible to control each step of the 1.2-second welding process by using the refined control technology, which selects a matching precision actuator combined with the dialog control. With the integration of Herrmann Ultrasonics Soft-Touch technology, it is possible to slow down the sonotrode right before it touches the part, creating a soft and clean weld joint.

HIQ DIALOG details

• Intuitive weld-process control
• Industrial PC with Windows XP
• Freely programmable HMC drive system
• Flexible force profiling
• Incremental positioning measurement
• Energy save mode
• Integrated workspace illumination
