CNC Milling Chucks Ease Tool Changes, Reduce Downtime
The Überchuck precision CNC milling chuck from Albrecht uses a two-stage clamping mechanism to increase gripping torque, rigidity and damping.
The Überchuck precision CNC milling chuck (formerly the Albrecht Power Chuck) from Albrecht uses a two-stage clamping mechanism to increase gripping torque, rigidity and damping. According to the company, these characteristics enable more efficient and aggressive cutting, increase tool life, offer easier and faster tool changes, and reduce downtime.
Companies concerned about strict quality requirements regularly check toolholder tapers for wear or inaccuracy because these conditions can jeopardize the results of a critical operation. However, a shop can check tapers quickly and reliably with air gages. These devices can be used effectively without special operator training. For measuring taper in a production environment, few other methods can match the speed and performance of air, as multiple-circuit air jets can be placed in very small taper gages.
I’ve said that the toolholder is the least appreciated element in many milling processes, but the pull stud (or retention knob) is perhaps the least appreciated component of the toolholder.
A reader recently asked about speed, feed rate and depth of cut when using small tools in steel.
