Short Collet Chuck

Form AD

The High Precision Collet Chuck JIS B 6339-2 BT is the collet chuck for the highest machining capacity in high-speed manufacturing. The universal High Precision Collet Chuck is a unique high performance chuck that can also be used with standard collets. High runout accuracy of 0.003 mm at 3 × D is possible to achieve in the short collet chuck without developing any deflection. For standard collets ER according to ISO 15488 (Please note when use with standard ER collets the gage length A will vary compared to A dimension given below). The short collet chuck is designed and manufactured to deliver high rigidity.

These chuck enables smoother running thanks to vibration absorbing geometry, therefore better surface quality and protection of tools, spindles and machines. These collet chucks have increased machining capacity due to higher spindle speeds, higher feed rates and larger cutting depths. Short collet chucks are highly preferred as they have shorter processing times, higher machining accuracy and high clamping force. These short collets are suitable for operating high-speed manufacturing and heavy milling. The chucks are manufactured with threaded holes in order to balance with balancing screws.
