Clever Hardtop EDAG Inc. (www.edag-us.com; Auburn Hills, MI) may be best known for its work in product development and manufacturing engineering, but it has gotten into the aftermarket business, as well, with an RTM (resin-transfer-molded) removable hardtop for the Pontiac Solstice and Saturn Sky.

Clever Hardtop

EDAG Inc. (www.edag-us.com; Auburn Hills, MI) may be best known for its work in product development and manufacturing engineering, but it has gotten into the aftermarket business, as well, with an RTM (resin-transfer-molded) removable hardtop for the Pontiac Solstice and Saturn Sky. The roof weighs 115 lb. It uses the existing mounting points and bolts of the convertible top at the front header and the rear deck lid hinge points. The firm used what it calls “OEM quality CAD/FED design, engineering and materials.” Evidently, if you have the resources, putting them to work in other arenas is a good thing to do. Price? $2,499.

 

Shaker

The DSX-8000 from Thermotron (www.thermotron.com; Holland, MI) is an 8,000-lbf (35.6-kN) electrodynamic vibration system. Its 16-in. diameter armature can produce accelerations up to 120 g. It can support payloads up to 1,000 lb, and provides a velocity of up to 120 ips. The control system permits sine, random, shock, and other operational modes. There is a user-selectable frequency range up to 3,000 Hz. One application: squeak and rattle testing.

 

On-line Marking

The MicroLiner 312 from Borries Marking Systems (Ann Arbor, MI; www.borries.net) can perform scribe, stylus, and dot matrix marking processes on parts. This includes DataMatrix marking. It has a marking window (X-Y) of 2 x 2 in. It marks at up to four characters per second. The device measures 160 mm high by 150 mm by 150 mm long, and weighs 3 kg. It can be fitted into production lines and placed at any orientation.

 

Adhesive Applicator

The Ultra FoamMix applicator mixes hot-melt adhesive with inert gas. The gas expands, forming a closed-cell foam. According to Nordson Corp. (www.nordson.com; Duluth, GA), the resulting material helps reduce adhesive consumption up to 50% while providing improved production and bonding performance. Also, there are increased open time, faster set times, improved wetting, and lower heat density. Applicators are available to melt and deliver up to 300 liters/hour of low- to medium-viscosity foamed material.

 

High-performance Drills

The “HARDCORE” technology used on drills available from ATI Stellram (www.atistellram.com; LaVergne, TN) has a core carbide grade that handles the slower speeds of the tool center and a wear-resistant outer shell. Compared with traditional single-grade solid carbide drills, these drills are said to provide four times the tool life, twice the production speed, and a 50% reduction in cost-per-hole.

 

Cylindrical Gear Grinder

The 300TWG from Gleason Corp. (www.gleason.com; Rochester, NY) can grind cylindrical gears with a diameter up to 300 mm. High-speed direct-drive spindles and Siemens CNC control facilitate use of multi-start grinding wheels; these wheels are said to be able to improve production rates by up to 10 times compared with conventional single-start wheels.

 

3D Safety Monitoring

The SafetyEYE system available from Pilz Automation Safety (www.pilz.com; Canton, MI) was developed by that company along with engineers from DaimlerChrysler in Germany. It consists of a sensing device (three cameras), a high-performance computer (which processes the input from the cameras and provides output), and a programmable safety and control system (which takes output from the computer). Consider application in a robotic workstation. The sensing device is located above it so that it views the operating range. The system is programmed such that there are virtual safety zones established. If a worker enters a zone where he is not in immediate danger, the system will reduce the speed of the robot arm and provide a signal to the worker. If the worker were to continue, then there would be a shutdown. This provides better control than systems that simply shut down operations.

 

Table Top Robot

The RS20 is a SCARA (i.e., “Selective Compliant Assembly Robot Arm”) robot from Stäubli Robotics (www.staublirobotics.com; Duncan, SC) that has a range of 220 mm. It has four degrees of freedom and a durable plastic housing. The unit is targeted for applications including small part assembly. The CS8C M controller is PC-based.

 

Erratum

The power supply figures for the InductoScan heat treating system published in the March issue (p. 66) are incorrect. They are: 150, 200, and 300 kW, 3-50 kHz and 45 and 90 kW @ 200 kHz.
