Pursuing a plate-cutting saw: Employees team up to make a buying decisionMetal Cutting Service, City of Industry (Los Angeles), Calif., specializes in sawing metals. President David Viel explained the company's strategy: "We do not buy or sell anything, we just add value to others' products." Although it does very little advertising, the 26-employee company has customers throughout the U.S., Europe, and Asia, even though the cost to ship material can be substantial.

Angling for a good cut: Sawing structurals and tubingGood 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.

Sawing? Cool it.: Coolants can extend blade life, improve cut finish, and quicken cut ratesNearly 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.

Making the most of your saw blade: Check the chips, watch for rips, follow other tipsRecognizing 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.

Sawing with the times: Band saw blades change as industry evolvesModernization 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.

Better safe than saw awry: Contract manufacturer promotes safety and gains efficiency by relying on lift truck and new saw loaderWhen a machine operator cut a bundle of barstock open to load into a saw, the bands popped, moving the blocks that were put there to safely contain the bars. The bars fell on the operator's foot and trapped it. Not wanting to duplicate that nightmare, engineers at Kirsan Engineering, Kenosha, Wis., set about to create a method of loading barstock that relied on lift trucks, not cranes.
