Derek Korn joined Modern Machine Shop in 2004, but has been writing about manufacturing since 1997. His mechanical engineering degree from the University of Cincinnati’s College of Applied Science provides a solid foundation for understanding and explaining how innovative shops apply advanced machining technologies. As you might gather from this photo, he’s the car guy of the MMS bunch. But his ’55 Chevy isn’t as nice as the hotrod he’s standing next to. In fact, his car needs a right-front fender spear if you know anybody willing to part with one.

Hybrid Lubricant Offers Advantages

At IMTS, I learned about an organic-urea-based (yes, urea) hybrid lubricant that takes advantage of oil’s liquid nature and grease’s adhesive characteristics. LHL (Lube Hybrid Lubrication) is available in the United States through Lube USA and is said to offer a number of advantages. It uses just a fraction of the lubricant quantity compared to conventional oil lubrications systems. The company says lower lubricant requirement can significantly reduce machine maintenance costs while minimizing the chance that lubricant will enter a machine’s coolant tank causing coolant deterioration and/or decomposition. Plus, the LHL hybrid grease doesn’t emulsify and is packaged in convenient cartridges that are simple to replace. Maintenance made easier.

The Value of a Photo

In my humble opinion, I think the cover photo shown above that I was able to take for our October issue was pretty cool. It punctuates the notion that significant tooling capacity is one necessary part of an effective 24/7 machining process (and this article explains R&G Precision’s efforts in that regard).  

But there was another photo I took, the one below, that also captures a lot in one shot.

It shows the tool crib area located behind R&G’s HMC cell that has an efficient layout enabling operators to quickly prep tools and material for upcoming jobs. This area includes a Zoller Smile 400 presetter, a Rego-Fix benchtop hydraulic press used to insert or remove collets from Rego-Fix Powrgrip toolholders, a saw to machine blanks, and carts to contain all the tools and material needed to load a job into the cell or one of the shop’s stand-alone machining centers. Plus, one of the shop’s machine operators is also a programmer, and his programming station is just outside this shot. This enables him to set up new jobs as well as create CAM programs on the shop floor.

Putting together words and sentences and paragraphs to tell stories like R&G’s is one thing I enjoy, but the challenge of capturing supportive, telling photos during a shop visit is just as fun.

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.

GF Machining Solutions Opens New “Center of Competence” Facility in Southern California

Last week, I attended an open house at GF Machining Solutions’ newest “Center of Competence” in Irvine, California, part of a 106,000-square-foot Georg Fischer facility shared with sister company GF Piping Systems. Established to strengthen support for West Coast customers, many of which serve the aerospace industry, the Center includes a machine demonstration area with high-speed machining centers and wire and sinker EDM equipment as well as solutions for laser texturing and automation. It also includes customer training rooms, resources for sales, service and applications staff, and an extensive spare parts and consumables warehouse.

Here are a few shots I took while touring the facility:

This Form 30 features an ATC design whereby the 26-position tool carousel wraps around the machine column unlike a conventional ATC that would consume additional floor space.


Note the removable access panel on the left side of the System 3R Workpartner automated pallet system serving a Form 200 SP wire EDM unit. This enables the easy addition of another EDM unit to share the automated pallet system. 


The company suggests that the precursor to automation is establishing a common part reference plane, which is possible using workpiece palletizing systems such as those offered by System 3R.


Toyota Racing Development in Southern California now uses five-axis machining equipment from GF Machining Solutions to enable faster, more accurate milling of cylinder head ports.

Are You Realizing the Value of Video?

LED cameras enable principals at Quality Tooling, located in Corydon, Kentucky, to see if a tool or EDM wire has broken. Select shop personnel can access camera views via their home computer or smart phone to check on equipment during off hours.

Today’s camera, computer, tablet and smartphone technologies (not to mention Google Glass) make taking and accessing video a snap, even on the shop floor. Here are a few ways shops can leverage this capability to become more efficient and effective.
