Röhm Products of America’s Duro-A RC power chuck reduces setup times because of its quick jaw-change system that enables the jaws to be adjusted, reversed or swapped out in 50 seconds. According to the company, traditional power chucks cannot keep up with the latest spindle rotational speeds and acceleration/deceleration rates because of the heavy weight and loss of dynamic clamping force. Thus, this power chuck’s billet steel body has a lightweight design and an overall height that is reduced by 14 percent, according to the company. This is said to boast centrifugal force compensation that enables fast speeds and feeds, as well as power consumption savings of as much as 17 percent. The chuck’s interchangeable back plate is said to further ensure convenient adaptability to fit a range of lathe spindles.
The rapidly increasing demand for high-value threaded parts with exceptionally high length-to-diameter ratios has created a lot of interest in thread whirling technology among American shops and manufacturers.
Producing a keyway, spline or similar longitudinal feature on a turned part usually necessitates an additional, time-consuming, secondary operation on a broaching or slotting machine. That means moving the part to and from a secondary operation, an extra setup, additional labor and hourly machine costs and all of the other headaches that go with secondary operations.
Workholding for turning is usually fairly basic: The selection comes down to chucks or collets. This article looks at when to consider the collet chuck and what kind might be best for a given application.
