So what if one saw cuts faster than another?

April 15, 2008 | By Werner Rankenhohn

Two similar saws might have significantly different cutting speeds, and given a choice, most fabricators would choose the faster saw. However, the saw's speed isn't the only factor that affects efficiency. Material handling before and after the cut also plays a big role in process efficiency. Fabricators who overlook material handling don't gain all they can in terms of increasing throughput.

Sawing with the times

December 11, 2007 | By Gerry Overstreet

Modernization has brought us many advancements, and two big advancements that fabricators must deal with are in technology and commerce. On the technology side, advancements have led to modern alloys; on the commerce side, we have increased globalization. Many modern ferrous alloys are harder to cut than carbon steel, and while the cutting is more difficult, globalization is increasing the competitive pressures and reducing the profit margins. Other advancements have modernized band saw blades, giving fabricators a fighting chance to stay profitable.

Making the most of your saw blade

November 6, 2007 | By Gerry Overstreet

Recognizing heat and vibration in sawing applications is easy. The tough part is finding out why they are happening. By becoming familiar with blade speed and feed rates, blade selection, and blade break-in, fabricators will find that the saw blade is productive for a longer period of time.

Bundles of Joy

July 10, 2007 | By Adam Popson

Using a band saw to cut bundles of structural shapes is good for productivity but bad for band saw blade wear. Knowledge of application-specific tooth designs, tooth pitch, band tension, band speeds, and cutting fluid will help maintain blade life.

Sawing? Cool it.

June 12, 2007 | By Adam Popson

Nearly every metal sawing operation can become more cost-effective with a properly mixed and maintained sawing coolant. Proper use of sawing coolant improves cutting rates by balancing the combination of cooling and lubrication of the blade. Quality coolant improves the cut finish and can extend blade life by as much as 20 percent.

Angling for a good cut

July 11, 2006 | By Al Terronez

Good sawing and maintenance practices can help alleviate problems that can occur when making angle cuts in structurals and tubing. Addressing the stock, machine setup, the blade, the cutting fluid, and the saw itself may not completely rid fabricators of problems, but it can help keep the operation profitable and relatively painless.

Cutting to the chase - integrating secondary operations

January 10, 2006 | By William Holyoak

Tube cut-off machines have evolved to integrate end forming and bending capabilities that normally are considered secondary operations. The suitability of a cutting method to be integrated inline with end forming and bending depends on each cutting method’s characteristics and the bending and end forming requirements.

Creating an efficient offline band sawing system Part II

December 13, 2005 | By Doug Harris

Planning an offline band sawing system can be complicated because it can affect, and is affected by, many interrelated factors. Breaking it down to infeed, sawing, and outfeed helps to frame the planning by breaking it down to three subprocesses. Furthermore, answering 15 pertinent questions can help you tailor an efficient sawing operation to your specific facility and sawing applications.

Miter sawing adds eye appeal to structural steel

August 10, 2004 | By David D. McCorry

As a structural steel fabricator, you may have operated a miter saw. The fact is, however, in many other shops the miter feature has rarely been used because, traditionally, most steel buildings—from the skyscraper to the humble warehouse—have been designed without miter cuts. Beam ends...
