Next Generation BR Series Power Chucks
January 1, 2020
The next generation Kitagawa BR Series power chuck achieves gripping accuracy of 0.01 mm T.I.R.
"The industry standard for repeatability (clamping a workpiece, zero out indicator, unclamp and re-clamp the same workpiece) with a set of formed jaws (where the jaws are turned to match the diameter of the workpiece) was 20 microns. The BR Power Chuck Series has increased this accuracy to below 10 microns. This degree of high accuracy machining can be accomplished now with the BR Series as a standard specification," said a company spokesperson.
A special set of Kitagawa patented T-Nuts, called "Tnut-Plus" allows machine shops to only form a set of soft jaws once with the BR Series Chucks. This eliminates the need to re-bore jaws each time they are removed from the chuck and replaced. The elimination of jaw re-boring means the BR Plus Chuck saves machine shops a significant amount of set-up time and labor costs. Using the example of three jaw changeovers per day, each changeover taking at least 30 minutes, the savings could be a minimum of 1.5 hours a day of machining time. Over a one-year period, this equates to approximately 450+ total labor hours saved. Regardless of shop labor rates, this results in many thousands of dollars saved and improved productivity on the shop floor.
"BR Series chucks come with a host of other improved features, benefits and specifications," said the spokesperson. They feature an extra-large through-hole (the same as the BB200 Series) as standard. Other features include reduced jaw lift when clamping, a reduction in grip force loss due to centrifugal force of up to 15% and all new body design that resets the bar for power chucks.
