Clamping honeycomb parts with ice
Mobile ice duo

Machining honeycomb type workpieces makes special demands on clamping technology. Neither conventional clamping methods nor vacuum systems have been able to create ideal conditions for 3D machining of these parts.
In contrast freeze clamp technology has become generally more and more accepted for clamping filigree and honeycomb parts.
Witte Bleckede has now developed a freeze clamp system, which works with two chucks at the same time. So while one chuck is in working process, parts can be prepared on the second chuck. Clamping or freezing of work-pieces takes approx. 30 seconds. Release or thawing is done in the same time frame. To clamp parts the chucks are moistened by hand with a little water, the parts are placed and frozen by activating a switch. The temperature is then continuously monitored, ideally at -10° C. The supply components such as refrigeration compressor, coolant tank etc. are housed in a cooling unit. The unit is equipped with castors enabling applications on different machines.
