{"id":"dn-solutions-puma-st-20gs-ii","model_id":"PUMA ST 20GS II","name":"DN Solutions PUMA ST 20GS II","summary":"The PUMA ST 20GS II is a Swiss-type turning center with a main spindle and a sub spindle, intended for continuous machining of small parts. It has a maximum turning diameter of 20 mm and a maximum turning length of 200 mm, with X- and Z-axis travels of 90 mm and 200 mm. The machine carries 23 tool stations and uses a built-in main spindle motor.","study_notes":["Main spindle speed is 10000 r/min with 3.7 kW; sub spindle speed is 8000 r/min with 3.7 kW.","X- and Z-axis rapid traverse are both 32 m/min.","Machine dimensions are 2367 mm length, 1245 mm width and 1733 mm height.","Four cross rotary tool holders are fitted as standard; up to five cross tools can be used for milling and special machining.","CBS (Chip Breaking Solution) is standard, breaking chips by repeated traverse of the axes; CBS Advanced adds screw thread cutting.","Supported machining modes include internal/external turning, R machining, grooving, cutting and drilling.","The series is described as suitable for parts with diameters from 20 mm to 38 mm, and the feature set applies to all Swiss-turn models and to selected 8-inch or smaller turning centers.","Specifications are stated as global standard and may differ by region."],"safety_notes":[],"sources":[{"url":"https://www.dn-solutions.com/global/product/turning-center/swissturn/puma-st-20-gs-ii.do","title":"DN Solutions","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","method":"llm_source_check"},"updated_at":"2026-10-26","type":"hardware","spec":{"category":"cnc_lathe","manufacturer":"dn-solutions","controllers":[],"weight_kg":2600,"travel_x_mm":90,"travel_z_mm":200,"spindle_max_rpm":10000,"spindle_power_kw":3.7,"rapid_traverse_m_min":32,"tool_capacity":23,"max_turning_diameter_mm":20,"max_turning_length_mm":200,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/dn-solutions-puma-st-20gs-ii","license":"https://creativecommons.org/licenses/by/4.0/"}
