SuperSmooth™ Rotary Laser Marking Systems Installed at Metal Craft (Elk River, MN)
for Medical Device Manufacturing
Metal Craft, a leading contract manufacturer of precision parts for the medical device industry recently put into production two LNA LASF Series fiber laser marking systems using our new SuperSmooth rotary laser marking technology.

Typical laser marking of cylindrical parts is done by covering a 10-15 degree angle, rotate the part and repeat until the full circumference of the mark is complete. This can result in voids, overlaps and indexing lines within the finished mark. Additionally, as the laser beam reaches the edges of the scan, it is slightly out of focus resulting in a mark with potential intensity variations. Jon Hillstrom, Finishing and Laser Marking Lead of Metal Craft added, “Our existing laser marking systems being ten years old, were not capable of the quality and accuracy required to meet our customers’ needs.”

LNA Laser, working with Metal Craft's engineers, pioneered the SuperSmooth spindle laser marking technique. This new feature allows the graphic or text is to be marked at a constant spindle speed where each line is marked at the precise laser focal point. This ‘Turn and Burn’ technique results in seamless marks with each laser pulse delivered at the ideal focus for incredibly high resolution, consistency and accuracy.

This development is of particular importance for instruments and devices requiring high contrast graduations, regardless of the substrate’s composition, e.g. metal, plastic, etc. It has also been shown to have esthetic value in creating intricate patterns for decorative or jewelry applications.

The History of New Years Celebrations
The earliest recorded festivities in honor of a new year’s arrival date back some 4,000 years to ancient Babylon. For the Babylonians, the first new moon following the vernal equinox—the day in late March with an equal amount of sunlight and darkness—heralded the start of a new year. A variety of other dates tied to the seasons were also used by various ancient cultures. The Egyptians, Phoenicians, and Persians began their new year with the fall equinox, and the Greeks celebrated it on the winter solstice.

In 46 B.C. Julius Caesar introduced a new, solar-based calendar that was a vast improvement on the ancient Roman calendar, which was a lunar system that had become wildly inaccurate over the years. The Julian calendar decreed that the new year would occur with January 1, and within the Roman world, January 1 became the consistently observed start of the new year.

In the United States, the most iconic New Year’s tradition is the dropping of a giant ball in New York City’s Times Square at the stroke of midnight. Millions of people around the world watch the event, which has taken place almost every year since 1907. Over time, the ball itself has ballooned from a 700-pound iron-and-wood orb to a brightly patterned sphere 12 feet in diameter and weighing in at nearly 12,000 pounds. Various towns and cities across America have developed their own versions of the Times Square ritual, organizing public drops of items ranging from pickles (Dillsburg, Pennsylvania) to possums (Tallapoosa, Georgia) at midnight on New Year’s Eve.
