Sawing? Cool it.

June 12, 2007

By:

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.

Bend process monitoring—small changes lead to big results

June 12, 2007

By:

Conventional quality control in tube bending operations usually means detecting the number of links on a tube bending mandrel. When such a system detects that a mandrel link is missing, it shuts down the system so personnel can discard the last bent tube and replace the mandrel. Unfortunately, the broken mandrel link usually is a symptom of a larger problem—one that may have produced poor-quality parts long before the mandrel broke.Another method, process variation monitoring, measures the tension on the mandrel and alerts the equipment operator when the tension changes. This lets the manufacturing personnel know that a problem is developing while it is still small and manageable.
