Electron beam welding robots are effective in a variety of different welding solutions. Due to their focused weld zone, they are provide precise, highly controlled welds. View our collection of electron beam welding robotics here:http://www.robots.com/applications/el…

Electron Beam Welding Robots: Electron beam welding (EBW) is a fusion welding process that joins two materials by using a beam of high-velocity electrons. The electrons produce kinetic energy that is transformed into heat upon impact, melting the workpieces and connecting them with a fusion weld.

Electron beam welding robots are effective in several different welding situations and they have a narrow weld zone. With such a focused welding zone, it allows for highly controlledwelding.

The electron beam is generated in a high vacuum. While it can weld in medium or non-vacuum conditions, high vacuum welding will provide maximum purity and high depth to width ratio welds.

There are several robot models available that can perform electron beam welding, including the FANUC S series and the Motoman UP series.

AUTOMATICA 2014: Robots for Metalworking – Wide-Ranged Offer for All Applications

 

It’s clear a few weeks before the start of AUTOMATICA, which will take place in Munich from June 3 to 6: the range of robot offers and complete solutions for metalworking has never been as comprehensive as today. The exhibitors at the leading world trade fair have the right solution on hand for practically every application.

The two big topics are: automation of machine tools and special robots for metalworking. While robots handle loading and unloading machine tools as well as upstream and downstream work steps in the first case, large six-axis robots take charge of milling cutters and operate as machine tools in the second case.

Automation of machine tools is trend topic number one. The use of robots increases overall productivity of modern machining centers – one reason for the tremendous growth rates in this sector. Because options for reducing the main times of machining processes have been exhausted, optimizing the auxiliary times is the only possibility, and they can be shortened significantly thanks to the use of robots. Additional benefits are minimizing machine downtimes and semi-automatic operation of machines in shifts without workers.

Two solutions are competing in automating machine tools: direct integration of robots into machines and cell concepts, in which complete automation modules including robots can be docked onto machine tools. Trade visitors to AUTOMATICA can obtain information about the advantages and disadvantages of both.

Many users have had very positive experiences with automation of machine tools in simple applications over the past years. Convinced of the process reliability of these systems, the trend today is going in the direction of highly developed automation solutions, as Manfred Hübschmann, Managing Director of Stäubli Robotics, knows from his own experience: “Robots are taking on increasingly complex work content all the way to complete machining, often equipped with automatic gripper replacement systems. In addition, solutions are increasingly in demand, in which robots not only automate machining centers, but also handle linking of production systems and consequently provide even more autonomy.

Be careful when selecting a robot
Today, almost all manufacturers offer six-axis robots for typical tasks. But careful: specific conditions of use play a decisive role in the selection of a suitable robot. In addition to a compact design with small footprint, precision and speed, users should pay attention to other features of robots.

When six-axis robots work inside a machine tool, they have to withstand the hardest production conditions.
The unavoidable contact with chips, sanding dust, cooling lubricants, cutting oils and other corrosive media make life difficult for them. Such requirements limit the range of usable robots considerably.

For applications, in which robots are continually exposed to liquid media, additionally protected robots are recommended. Pioneers in this field were the Stäubli six-axis robots in HE design, which were designed specifically for use when exposed to spray water. The wrist joint of this machine has IP 67 protection and can be dipped into liquid media. Kuka is following suit at AUTOMATICA. Waterproof models of the recently started KR Agilus series are available effective immediately.
“Thanks to their new waterproof properties, the KR Agilus series functions perfectly in the hardest production conditions and handles loading capacities from six to ten kilograms with ranges of 700, 900 and 1,100 millimeters. Stable stainless steel covers, special surface treatments and numerous gaskets enable unrestricted use of our small precision robot in machine tools,” according to Andreas Schuhbauer, Key Technology Manager at Kuka Roboter GmbH.

The development departments at ABB, Fanuc, Epson, Yaskawa and other robot manufacturers are also working on this topic, so that additional pioneering innovations can be expected at AUTOMATICA. In this context, not only the manipulators are the focus, but also software tools and open interfaces to the machine tools, which make programming especially easy without the need of special skills. Thanks to progress in control systems, robots can already be programmed via control of the machine tools in many cases.

Robots as machine tools 
Large six-axis robots are competing with machine tools for specific applications in the meantime. All kinds of materials can be machined with correspondingly modified robots. Application possibilities include milling,
trimming, drilling, thread cutting, polishing and the like. Robots for such uses should be especially precise and have a rigid structure to ensure usable machining results.

In metalworking, Manfred Hübschmann still considers CNC machining and machining robots such as the Stäubli RX170 hsm only conditionally as competitors: “High-precision machining of a large number of metal parts will remain a domain of machine tools. In small series and in places where precision within the range of tenths of a millimeter suffices, robots can be an economic alternative to be taken seriously. In principle, both solutions have their
own markets.”

Go-Kart Arc Welding: http://www.fanucamerica.com/Products/…

The largest member in FANUC America’s family of Arc Welding robots, the FANUC ARC Mate 120iC offers the largest motion area of any arc welding robot in its class, and a solid payload of 20 kilograms, all while maintaining a conveniently compact size and high speed. This robot features a slim arm with internally routed cables, and a compact base that is beneficial in accommodating multi-robot systems.

In this video a FANUC ARC Mate 120iC demonstrates dynamic welding of a go-kart frame. A variety of robotic arc welding advancements from FANUC America are used in this demonstration. After finishing a weld cycle, the robot moves to a tip reamer where the welding tip is cleaned off. The robot then places the weld tip into FANUC’s iRVision TorchMate weld tip inspection station. Once the weld tip is verified, the automated weld process for the go-kart frame begins. The robot and a two-axis positioner to which the go-kart frame is attached use coordinated motion to trace the weld path with excellent precision.

The iRVision TorchMate weld tip inspection feature works with a variety of welding processes, and is designed to reduce bad welds by monitoring bent torches and tip wear. It features an easy menu setup with results displayed on the teach pendant to perform integrated diagnostics. The inspection component is pre-packaged with easy connection and setup that requires no engineering. Once the frame is fully welded, the robot moves to the tip reamer, iRVision TorchMate for weld tip inspection, and the cycle repeats.

Advancements in robotic arc welding technology, along with FANUC America’s focus on continuous improvement, have helped FANUC continue to provide manufacturers with world leading robotic welding automation. To learn more please visithttp://www.fanucamerica.com.

Vickers Engineering – Manufacturing with Robots & Automation Drives Growth

Publicado el 21/03/2014

Vickers Engineering, a New Troy, Michigan-based manufacturer, is growing at 20 to 30 percent annually with the help of robots and automation.

According to Matt Tyler, Vickers president and CEO since 1999, the company had 35 employees when he took the reigns 15 years ago. Now, the Tier 1 supplier has nearly 200 highly-trained employees working in conjunction with 12 robotic cells to produce parts locally for global customers.

“Automation has been a critical driver in that it has provided us with a more predictable process, higher quality, improved product flow, and most importantly, it’s made us competitive globally,” said Tyler. We’ve acquired customers from all over the world and we’re producing the parts right here in Southwest Michigan.”

Tyler emphasizes the need for more work force training as well as increased technical education for future workers. “The skill sets required to work with automation are higher, which means qualified workers will be able to achieve better and higher-paying jobs.”

Vickers plans to incorporate additional robots and automation at its facility in the near future. “There’s a lot of room for us to grow with the automation, and we’re looking forward to it,” said Tyler.

Robotic Case Palletizing and Stretch Wrapper System – Courtesy of Kaufman Engineered Systems

FANUC Authorized Integrator Kaufman Engineered Systems apply FANUC robot technology to provide customers complete end of line system solutions, including automated systems for robotic palletizing and depalletizing, stretch wrapping, material handling and case packing.

The system seen here is Kaufman Engineered Systems’ dual tote and case palletizer. This system features two FANUC robots, a single position transfer car, a simultaneous two-pallet type dispenser and a turntable stretch wrapper. A FANUC M-410iB/700 Robot seen on the right palletizes 1,100-pound totes with a custom designed spatula end-of-arm tool. However this isn’t the only type of tool this robot can use for picking boxes of product. Through the use of an ATI tool changer, the same robot can switch its end-of-arm tooling to a vacuum gripper when necessary.

A second FANUC robot, seen on the left, is also utilized in this system – The FANUC M-410iB/160 Robot. This extremely versatile palletizing robot displays its flexibility by picking and palletizing cases from two separate conveyor lines with its custom-designed vacuum end-of-arm tooling. Once a pallet is finished, it is conveyed out of the system to Kaufman’s automated stretch wrapper.

With Wonderware HMI interface controls and Kaufman-built conveyors, controls, stretch wrapper and integrated labeling, this system is able to palletize and stretch wrap 10 different SKUs in up to 25 loads per hour from 2 different lines.
