Clamping tool Precision milling: Digital torque wrench securely tightens collet chucks
The new Digital Mega Torque Wrench from Big Kaiser achieves the secure and accurate tightening of collet chucks. The new wrench has a user-friendly digital interface and interchangeable head sizes.
The new Big Kaiser torque wrench has multiple settings to ensure the right torque is applied to the clamping of cutting tools. The recommended torque for each compatible Big Kaiser collet chuck model is pre-set, and the correct tightening torque is easily available by simply choosing the model to be clamped. With a clear display, the torque wrench is easy to use and it combines a four-digit digital display with a high-precision five-level LED bar graph. When tightening is complete and the recommended torque is reached, the wrench vibrates and emits a warning beep, to alert the user.
“Having correctly clamped tools is extremely important for all collet tool holders. Precision and holding force can only be guaranteed with tools that have been clamped with the right torque setting,” said Giampaolo Roccatello, Chief Sales & Marketing Officer for Europe at Big Kaiser. “Additionally, manual assembly holders have a far longer lifetime than heat shrink holders that wear out a little every time they are clamped. This means they are better for the environment and cheaper for the user.”
The Digital Mega Torque Wrench provides a cost-effective alternative to torque measurement machines. According to the company, it is a more flexible option than regular torque wrenches that have a very limited clamping range. Historically, a customer would require many wrench sizes to cover the entire range of Mega6 to Mega20 collets — this is no longer the case. The new torque wrench is also a better choice than typical freewheel wrenches that do not have any torque indicator, which results in the tool easily being clamped too much or too little — a factor that can significantly impact precision.
The torque wrench is powered by a built-in lithium battery that provides up to 4,000 tightening operations from a full charge. The battery takes three hours to recharge and has a lifetime of approximately 500 recharges. The Digital Mega Torque Wrench is designed for use with cylindrical nuts up to 46 mm and can be used with Mega Micro, Mega New Baby, and Mega E chucks. The wrench has a torque range from 5 to 50 Nm.
