Tsugami Corporation introduced a new fixed headstock "chucker" configuration of the SS32 Super Swiss Turn. The SS32L is capable of producing complex parts complete from ground or cold rolled barstock.

A typical Swiss machine will produce a bar remnant equal to the headstock stroke of the machine. In a chucker configuration, the headstock is pushed forward into the tool zone, substantially reducing the remnant. Manufacturers will be able to produce more parts from each bar, reducing expensive waste and increasing productivity.

Complex parts can be produced complete from barstock on the SS32L. Live face and cross tools for main and subspindle efficiently handle complex geometries on both sides of the part, resulting in more balanced machining. An optional adjustable angle-driven face attachment can be used for angled drilling, milling and thread whirling. With 320 mm (12.6") of headstock stroke, the machine can easily machine long parts, according to the company.

Like its predecessors, the SS20 and SS32, the SS32L also is designed to offer users a modular tool zone, increased capability over previous gang type models, and a roomier tool zone for easier setup. As shorter runs pervade, machine operators need to change part runs quickly. Sometimes the parts are different from each other, requiring completely different tool setups. The SS32L’s standard main spindle configuration includes seven turning tools, five cross rotary tools, and five ID tools, while the standard subspindle setup includes four ID stations, two face drills and two cross rotary tools. Quick changes to the configuration of main and subspindle cross rotary, ID and turning tools can be made, allowing for efficient machining of a larger variety of parts. The SS32L comes with CAD/CAM software.
