The Kaltenbach KKS 401 Full Automatic CNC Metal Saw is a used metal saw — sometimes referred to as a cold saw or circular cold saw — designed for precision cutting of metal profiles, sections, and bar stock. Kaltenbach is a well-established German manufacturer specialising in steel processing and fabrication machinery, supplying equipment to structural steelwork, manufacturing, and metalworking industries worldwide.
This machine is configured as a fully automatic CNC unit, meaning the entire cutting process — from feeding material to removing cut pieces — is handled without manual intervention. The saw blade is positioned automatically via a CNC-controlled turntable capable of rotating up to 180 degrees in both left and right directions, allowing angled cuts across a wide range of mitre settings. The system includes automatic zero-point recognition, ensuring consistent and repeatable reference positioning at the start of each job.
Material handling is fully integrated. A workpiece storage unit with an automatic roller conveyor feeds stock into the machine automatically, with the feed system pulling the workpiece toward the blade. Each single feed movement covers a maximum of 2,000 mm, and repositioning is supported to accommodate longer lengths beyond that range. After each cut, the finished piece is automatically fed out by up to 1,000 mm, then deposited onto an unloading table equipped with chains for orderly removal.
The cutting tool accepts saw or abrasive discs up to 425 mm in diameter, and blade turning speeds range from 6 to 30 m/min, allowing adjustment to suit different materials and cutting conditions. The machine's motor power requirement is 5.5 kW. Programming is handled through a CNC controller that stores multiple programs, each containing different sawing tasks or cutting sequences, enabling automated batch processing with minimal operator input.
The machine is located in Belgium and is offered used with CNC full-automatic accessories included.
