Looking to Lower Lighting Costs?

The Mach LED Plus replacement lighting fixtures can provide as much as 70 percent energy savings and can be connected via a common M12 plug connector.

Although the cost of electricity in the United States is low compared to other countries, U.S. manufacturers continue to look for ways to reduce energy consumption. Lighting is one area that they commonly target. However, savings can be realized by changing not only overhead facility lighting to more efficient units, but also equipment lighting fixtures.

For example, Waldmann Lighting Company recently introduced its newest industrial fixture, the Mach LED Plus, at IMTS. The company says this energy-efficient LED upgrade for traditional fluorescent tube luminaires can provide as much as 70 percent energy savings compared to luminaires with fluorescent lamps and also offer much longer service life.

A key design element is the system’s ease of installation. The Mach LED Plus adds LED technology to the same form, dimension and connection options of fluorescent tube luminaires being used in many of today’s industrial applications. The 2.75-inch diameter enables the use of existing brackets eliminating the need to drill additional holes (specially designed brackets are available for flexible adjustment of the luminaires). These units are available in six lengths ranging from 14 to 42 inches and can be connected via an M12 plug connector to either a low-voltage (24-volt) source or 100-, 120-, or 220/240-volt sources.

Video: Trial Cuts with Ultrasonic-Assisted Machining

A video created by Acoustech Systems includes footage of holes being drilled with and without ultrasonic-assisted machining. This company’s newly developed system is essentially a toolholder that has ultrasonic actuation built in. Adding this toolholder to the process can actually increase a shop’s machining capacity, because standard machines and tools can cut faster thanks to the friction reduction that the ultrasonic effect achieves. Comparison cuts in the video seen here show a standard drill doubling its speed and cutting more smoothly in both 1-inch-thick steel and 1-inch-thick titanium.

Centerline Issues for Turning Inserts

Photos of sample inserts such as this one illustrate wear patterns that help diagnose cutting tool misalignments in turning.

Tooling expert Mike Fagan suspects that many programmers and machinists could use a refresher on the importance and effects of insert alignment in turning operations. This short, amply-illustrated paper is his effort to clear up some of the misunderstanding. 

It covers signs of misalignment and suggests ways to fix problems, with additional tips and advice to improve turning operations. To find the paper, click here.

Sandvik Coromant Opens Newly Renovated U.S. Headquarters

An event yesterday at Sandvik Coromant's U.S. headquarters in Fair Lawn, New Jersey, celebrated the opening of a new Productivity Center (photo above), part of a now-completed 2-year renovation of this site.

The layout, architecture and offerings of the site now match other, more modern Sandvik locations both in North America and around the world. The company's original Fair Lawn site was built in 1955 and significantly expanded in 1966. Since then, priorities have shifted.

One of the priorities today is collaboration. An open design encourages movement through the facility and interaction among both employees and guests at the site. Within the Productivity Center (Sandvik's term for its training and process-development facilities), spacious machining areas equipped with sophisticated CNC machines provide capacity for company personnel to be working with various customers on various different projects at any given time. A machining area that is not so open (the ITAR-certified shop can be closed off, and frosted glass blocks the view) provides machining capacity for customer projects that are sensitive or secret.

Another priority, as company president Klas Forsström stressed in his remarks at the event, is outreach. This latest investment in the company's U.S. presence is coupled with an awareness that it needs to support manufacturing here by attracting talented people into this field. As it also does at its Chicago-area Productivity Center, for example, the company will routinely seek opportunities to bring groups of young people and their parents and teachers into the new New Jersey site in order to provide an up-to-date view of manufacturing technology, as well as an appealing glimpse at what a modern manufacturing career could look like for those who might thrive in this field.

A Square Hole for a Square Peg

This interior shot of AutoCrib’s TX750 tool vending system shows its vertical columns of adjustable shelves. To the left, you can see the inside of the system’s rolling dual-tambour door, capable of opening 2" to 60" to correspond with the selected bin.

Many industrial vending systems on the market today are based on pie-like trays divided into wedges. An operator calls up a tool or other expendable, and round carousels rotate until the appropriate wedge faces out. The operator can then open the door and remove the drill, insert or whatever it may be.

The system has its advantages, but according to Stephen Pixley, founder of AutoCrib, the wedge-shaped spaces also pose a dilemma. “Things come in rectangular boxes,” he points out, which means that in stocking the wedges, companies must waste either time (unpacking the boxes) or space (storing a square or rectangular box in a wedge-shaped hole).

Rather than pie-shaped trays system, AutoCrib’s TX750 vending system uses a carousel with slots more accommodating to box-shaped contents. The vending system features columns with adjustable shelving to accommodate boxes—as well as other objects of varying shapes and sizes. The slots can be adjusted to hold everything from a tiny insert to a 2-foot-plus fluorescent light bulb. The customizability of the slots reduces vertical bin height waste and increases the capacity that can be stored within a compact footprint. As many as 900 bins can be packed into the unit, which occupies 9.8 square feet of floor space.

The TX750 has another advantage that enables it to provide just the right product at the right time: rolling dual-tambour doors. When an operator calls for a product in a particular slot, the two doors rotate to the appropriate shelf and open only that slot. The doors can open to anywhere from 2" to 60" in half-inch increments.

The vending system is controlled by AutoCrib’s user interface with 19" touchscreen, and a native bin assignment process simplifies stocking the unit on the fly. Operators can identify themselves with an ID card or a fingerprint and search the system to retrieve items.
