The revolutionary Hardinge / EMAG joint venture produced VL machines provide a guaranteed load / unload time of 4 - 6 seconds - chip to chip - which is critical for cycles of 30 sec and less.
The benefits of using collet chucks in place of jaw chucks include the following.
* Lighter weight, no hoist required to mount on spindle.
* Faster job setup time than a jaw chuck.
* Faster acceleration and deceleration times due to less weight and smaller diameter.
* Higher spindle speeds for reduced cycle times.
* Optimum gripping with higher precision capability.
* Capable of using master collets and pads.
* Improved part concentricity over jaw chucks.
* Eliminate time spent on boring jaws.
* No hazard of jaws flying off.
