VOLLMER innovates circular saw blades with CC 355 production system

 Thursday, February 9, 2017

Untitled-1 copySwabian sharpening specialist VOLLMER is speeding up the manufacture of carbide-tipped circular saw blades with its CC 355 production system. The CC 355 enables circular saws for cutting wood to be fully sharpened – including all tooth faces, tooth tops and side angles – in a single working cycle. Four grip arms carry the saw blades from the loading system to the three machining stations automatically. Tooth faces, tooth tops and side angles can be machined in any order to produce even large volumes of circular saw blades with precision.


Joiners, carpenters and furniture makers all use hand-held and table-top circular saws to cut pieces of wood or chipboard to size every single day. This means that the demand for circular saw blades that are premium quality yet cost-effective is high. VOLLMER, the German sharpening specialist based in Biberach an der Riß, has developed the CC 355 production system for manufacturing carbide-tipped circular saw blades. This system is based on a machine concept that has been designed to fully machine circular saws in a single working cycle. The CC 355 sharpens the tooth face, tooth top and side angle of saw teeth at the same time, working through up to 800 teeth per hour. The VOLLMER system can produce large volumes of circular saws with a diameter of between 150 and 355 millimetres.


“The linchpin of our CC 355 is sharpening technology for carbide-tipped circular saws that has been over six decades in the making and that we have continued to improve ever since its creation,” says Dr.Ing. Stefan Brand, CEO of the VOLLMER Group. “Its automated system makes the CC 355 perfect for saw manufacturers who want to produce large volumes of parts and who also place exacting demands on the tools they use for woodworking.” Stefan concluded.


The CC 355 is equipped with two machining stations for tooth faces and tooth tops, plus one station for side angles. Circular saw manufacturers can position the stack of unmachined parts either on the left or on the right, which means that users are free to choose the direction of the machining sequence and the order in which saw teeth are machined. A total of 17 CNC axes precisely control the procedure in order to fully machine all known tooth geometries in just one cycle. An integrated handling system with four grip arms passes the circular saws securely from one station to the next. The intuitive VOLLMER operating concept employed in the CC 355 makes the system easy to operate and gives users a complete overview of each machining station. Users can take the mobile control panel with them from station to station.
