Robotic Inspection System with 3D Vision
ABB’s signature display combined the flexibility and productivity of robotic manipulation with state-of-the-art inspection technology. The company’s new robotic-inspection system with integrated 3D vision uses digital scans to detect defects on manufactured parts. The digitalization inherent to ABB Ability, a range of the company’s optimization and automation products, monitors the status of all welding-system components, delivering timely and actionable information. The system consists of a 3D white-light scanning sensor mounted to the arm of an ABB robot, relying on the agility of the robot to provide the precise movements necessary for the sensors to access most areas of simple and complex parts from the optimum angle. Sensor technology rapidly records and compares detailed geometric and surface data with digital CAD models, enabling the automated inspection of manufactured parts and pieces. The payoff: Users can reduce cycle times while raising quality and reducing the risk of quality-control errors.
In the FABTECH display, a sensor mounted to the arm of an ABB IRB 4600 robot (a general-purpose model optimized for short cycles) simulated the inspection of a metal component spot-welded by an IRB 6700 Lean ID robot (a medium/heavyweight model featuring an ABB spot-weld gun). A compact, high-payload-capacity IRB 2600 robot shuttled the part between the inspection and spot-welding robots.
Economical Compact Waterjet Cutting for Prototypes and Low-Volume Work
Omax Corp. debuted the unique ProtoMax abrasive-waterjet machine, designed for prototyping, light industry, technical education, artists and the maker movement. Its show-floor demonstration drew a large, inquisitive crowd at FABTECH, especially those looking to cost-effectively explore waterjet-cutting technology as an addition to their fabricating businesses.
ProtoMax proves ideal for prototyping and relatively low-volume cutting of almost any material less than 2 in. thick. It brings all the versatility benefits of larger machines in a compact package that can well-serve small job shops, engineering classrooms, makerspaces and personal use, according to Omax officials. It also can be an ideal addition for large shops that need occasional waterjet capabilities to complement other capabilities.
Delivering 30,000-psi cutting power with a 5-hp pump, ProtoMax submerges work material in water for clean, quiet cutting that won’t disrupt a shared workspace. Intelli-Max software controls programming of part files and the cutting operation.
“It’s easy to program even complex paths on the ProtoMax,” says Stephen Bruner, Omax vice president of marketing. “We’ve taken many of the same popular CAD/CAM software features that we use in our industrial waterjet systems and incorporated them into this machine.”

Preconfigured Welding Packages
Kuka‘s new ready2_use preconfigured welding packages drew the attention of FABTECH attendees. The solutions, which can be integrated into existing production environments, include the ready2_arc package that combines Kuka KR Cybertech nano and KR Cybertech arc nano robots with Miller Auto-Continuum 350 and 500 power supplies. This package is for typical welding tasks—thin to thick sheet carbon steel, aluminum or special welding modes for root-pass, narrow-gap or deep-penetration welding seams. The Kuka ready2_spot uses servo guns for the quick and easy implementation of spot-welding applications when joining steel and aluminum parts.
Entry-Level Punch-Laser Combo
The TruMatic 1000 Fiber, Trumpf’s first entry-level punch-laser combination machine with a solid-state laser, attracted expo attendees due to its modular design that enables users to add to it as business grows. The patented Delta Drive moves the electric punching head and the laser along the Y-axis while the sheet moves in the other direction. This reportedly increases machine dynamics, productivity and process stability, contributes to a significantly compact footprint, and enables material handling options such as the SheetMaster Compact.
The machine’s integrated protective housing automatically moves out of the way during punching operations for maximum visibility and accessibility. Decreasing relative movement between the machine table and the sheet also reduces the risk of collisions and makes the process more reliable overall. The machine will automatically sort finished parts to 7 by 7 in.—processed parts move down a chute for sorting into a series of four boxes positioned below the machine for easy removal. Alternatively, an additional extra-large flexible parts flap provides users with a second choice for part sorting. Equipped with a sensor that detects whether all parts have been properly ejected from the machine’s working area, this solution can be used to eject long and wide parts into containers as well as onto conveyors or pallets during punching and laser operations.
New Family of Servo-Hydraulic Press Brakes
Six months after new owner Right Lane Industries LLC acquired Pacific Press Technologies, the company used FABTECH to launch its Blaise family of servo-hydraulic press brakes. A working 175-ton model, with a 12-ft. ram, produced mobile-phone/business-card holders to showcase some of its bending capabilities for visitors.
The Blaise family offers capacities of 175, 250 and 350 tons with maximum bending lengths of 10, 12 and 14 ft. These press brakes feature industry-standard Delam CNC controllers. To maximize machine uptime, the company integrated components with a proven history of high mean-time between failure from its larger press brakes into the Blaise line. And, as the company’s founders leveraged their knowledge in developing hydraulic technologies for U.S. Navy jets to construct metal-shaping systems, the Blaise line was created to enable the user to experience a fighter-jet-cockpit operation. This is accomplished by attaching the controller to a pendent arm, where the user interface comes to the operator. Through the interface, drawings can be uploaded via a shop’s network, resulting in job-changeover efficiencies, especially for smaller batch runs.
To accomplish minimized ram deflection and its contribution to variances, hydraulic cylinders are trunnion-mounted, resulting in a lesser degree of freedom. Also, this mounting design moves the cylinders toward the center of the ram, which increases bend reproducibility.

Solid Welding Wire Reduces Rework
ESAB Welding and Cutting Products debuted Purus 42, a solid wire available in diameters from 0.030 to 0.062 in. The wire can reduce post-weld cleaning time and unplanned downtime associated with spatter, reduce or eliminate downtime for removing silica islands in multi-pass welding, and reduce or eliminate paint-related quality issues. New metallurgy enables Purus, classified as an AWS ER70S-6 EN/ISO G3Si1 wire, to reduce formation of silica islands so that slag self-releases or easily brushes off. The wire is available as a bare wire or with a copper coating.
Purus reportedly is ideal for high-volume semiautomatic and robotic applications, with Esab officials noting that one manufacturer of construction equipment reduced arc-ignition errors by 66 percent in multipass applications when using the wire. Previously, according to a company official, excess silica islands prevented positive arc ignition, and when this occurred, the manufacturer needed to shut down the robotic-welding station, spending an average of 3 min. to clean the silica islands. Given the station’s hourly rate of $280, each stop cost $14.
Purus meets all the technical requirements for an S-6 wire, enabling users to change wires without requalification, and offers batch-to-batch consistency due to tight control of element ingredients. The wire also provides good wetting so that the weld puddle flows well and with a smooth transition at the weld toe. And, by creating a good bead profile and surface appearance, it can reduce or eliminate the need for gas-tungsten-arc dressing or grinding to remove stress concentrations.

Automation Module Fits Small Press Brake Like a Glove
Bystronic introduced a mobile automation module for its Xpert 40 press brake. The result is a compact solution for automated as well as manual bending. Users can process large lots with the automated bending cell, and also bend small lots or individual parts manually when necessary. Just plug in and start bending. Setup of the robotic system takes just a few minutes.
Also introduced at FABTECH were two new options for the Xpert 40 (shown): a bending-line laser, which enables part bending without using the backgauge, ideal for conical parts and others that do not provide a stop position; and an optical footswitch control to optimize versatility and ergonomics.
Cutting Wheels Prevent Loading When Finishing Aluminum
Weiler Abrasives Group introduced the newest addition to its lineup of Tiger aluminum cutting, grinding and combo wheels. The new offering features a nonloading formula that keeps the wheels from gumming up, allowing operators to get more work done in less time. Further, their extended wheel life reduces changeovers and lowers cost-of-use to improve productivity and the bottom line.
“Fabricators know aluminum can be challenging to work with because of its low melting temperature and tendency to load and stop cutting,” says Rick Hopkins, Weiler’s senior product manager—metal fabrication. “We designed this new line of cutting and grinding wheels to help address those challenges.”
The new wheels complement the company’s Tiger Aluminum resin fiber discs, Tiger Ceramic Saber Tooth flap discs, nonwoven products and power brushes.
