• Clarren Helmet: This design was originated by Sterling Clarren, MD, in 1979 to treat infants with deformational plagiocephaly. It is made from a plastic shell with a thin liner for comfort. All the modifi cations are built into the helmet from the start, so follow up appointments are less frequent than with other types of orthoses. This design comes with a chin strap to help suspend the orthosis on the infant or baby’s head.
Design and Manufacturing Process
There are two alternative paths in making custom-fi tted remolding bands and helmets, the traditional way and the modern method based on modern tools. In the traditional way, the orthotist place a nylon stocki- nette on the baby’s head. A cast (negative) impression of the head is taken using plaster or plaster bandages (splints). The plaster material sets in between 15–30 min. As the cast is removed the orthotist will make marks where the eyes, nose,

The Truth Is: Runout greatly influences part quality and tool life. Furthermore, a small tool size accentuates any runout in the spindle, tool holder and collet. At the “acceptable average” runout of .0005”, our tests show tool life is generally cut in half. Tool life in most applications can increase over 200% when the BIG Daishowa Mega Chuck system is utilized due to our highly accurate and repeatable, Class AA, New Baby Collets.
The notch-free nut design of our Mega Micro Chuck prevents vibration at high speeds for superior balance and concentricity. It not only eliminates whistling noise and coolant splattering, but also assures increased strength of the nut itself. The super slim taper design of the body offers added strength for micro end milling, and reduces interference in long reach applications.
