The Computerized Lathe Charger chucks the geometrically centeredblock and rotates it for laser scanning while simultaneously raising andrepositioning both ends optimally in order to maximize veneer recovery.After the block has been perfectly repositioned, a precision pendulumblock transfer device precisely transports it to the lathe spindles. Thisfast and accurate positioning contributes to production speeds of up to18 cycles per minute.Sophisticated centering algorithms adjust to the unique shapes andcharacteristics of different species. The charger frame is of heavy-dutysteel construction to control deflection and accuracy and is designedfor direct attachment to the lathe for added rigidity and to assureprecise reference between the lathe and charger. Decades of lathecharger experience has resulted in a simple to maintain design with fewmoving parts.
