FABRICATION
Today’s fabricating technology promises the ability to produce high-quality components job after job, in a variety of applications. And, in each issue, MetalForming is committed to informing you on how fabrication equipment delivers.
In May, we take a close look at automated material handling via a visit to Fab Metals, an Ohio fabricator that employs the technology to increase throughput on its new fiber-laser cutters. MetalForming also details how RKM Design has found success through a new waterjet-cutting machine. And, learn how advancements in nesting software can net big gains for fabricators. This month in Welding Well, the conversation revolves around gas- metal-arc-welding challenges and solutions.

25 Laser-Focused on Throughput
To meet rising demand for fabricated-metal products, Fab Metals purchased a 6-kW fiber laser in 2017, and three months later brought in another, an 8-kW model.

Versatile, Lightweight Lamp-Post Cranes
Engineered Material Handling (EMH), Valley City, OH, has debuted its versatile AL System lamp-post workstation cranes, offering workstation-placement solutions that provide convenient access for optimum efficiency. Economical, easily installed and maintenance-free, the cranes feature lightweight aluminum track profiles for loads to 2200 lb., an exclusive EMH T-slot design, anodized enclosed rails and anti- kickup nylon wheels.
The cranes require only four upright
columns per runway cell, with the crane
runway clamped onto the top of the frame
at the corners using standard aluminum clamps. The bridge and lifting devices then are hung from the runway, which enables convenient and open access at either end. Maximum height is 15 ft.
With lightweight aluminum track profiles, AL System cranes are easily configured to suit almost any application and accommodate a variety of lifters and handling devices, safely and efficiently, according to company officials. Anodized aluminum extrusions and enclosed rails maximize strength, provide durability and add to aesthetics. The articulating cranes are free-moving and do not require movement at right angles. This feature also provides smooth operation and a low starting force, even with the load con- centrated at the end of the bridge. In addition, the crane’s anti-kickup nylon wheels deliver smooth and safe movement of the trolley inside of the enclosed rail.
An exclusive T-slot design allows for splicing of two pieces of rail together. This makes for simple installation with a variety of integrating equipment, such as lifters, end-effectors, chain hoists or smart lifters. The T-slot splice design also eliminates bumps when a load moves over track splices.

Unique Spindle-Retention Knobs Optimize Machine-Center Productivity
Custom fabrication and machining shops, as well as tooling suppliers, report benefits and quick ROI from using high-torque retention knobs from JM Performance Products, Inc. (JMPP), Fairport Harbor, OH. JMPP, a manufacturer of CNC-mill spindle-optimization products, designed the knobs to be used in existing toolholders to eliminate the bulge at the small end of the holder (see drawing), which stops it from making full contact with the taper of the
spindle. The knobs over-
come what the company
claims is a key design
flaw inherent in CNC v-
