The CMT 330 is a three-side trimmer designed for the on-demand printing environment. It features full digital control of the trimming process – servomotors control all adjustments normally done by hand with a traditional trimmer. Just key in the starting size and the finish size, and the trimmer takes it from there.

The control panel features a graphic LCD display of the job being trimmed. For repeat jobs, the CMT 330 can store 99 book trimming jobs in its memory. It can be used in line with perfect binders, or used off-line in a manual feed mode

The new Challenge CMT 330TC has expanded capability to finish cut LANDSCAPE FORMATTED BOOKS up to 12.1” (307 mm) tall by 12.9” (328 mm) wide and down to 5.875” (149 mm) tall by 3.937” (100 mm) wide.  Designed and built in Michigan-USA, the CMT 330TC utilizes powerful hydraulic cutting and clamping pressure to effortlessly cut up to a 2” (50.8 mm) thick book.

The CMT 330TC utilizes servo and stepper motors to accurately position books for cutting.  Full digital control of the set-up allows book size changes in less than 6 seconds.  There is no need to perform manual adjustments or exchange book clamps.  The CMT 330TC exclusively features simultaneous in-line and near-line feeding capability.  This allows the trimmer to automatically switch between feeding books directly from an in-line perfect binder or from a manually loaded near-line book pile feeder.  If one system is waiting for the next book, the other system can feed the trimmer to provide maximum production throughput.

The CMT 330TC Trimmer incorporates the most advanced book trimming technology available.  The new 10.5” color touch screen display, easy to use operator interface and smart diagnostic assistance makes the CMT 330TC the leader for operational simplicity.  Automatic size detection of the pre-trimmed book makes job programming easy, requiring the entry of only three dimensions.  Alternatively, the integrated bar code reader can scan the trim dimensions from a pre-printed barcode on the cover to adjust the knife settings automatically.  Simply stated, the CMT 330TC is a fully automated book-of-one trimming solution.
