Swiss-Type Lathe for Micro Components

Tsugami’s PO3 Swiss-turn CNC precision automatic lathe is capable of producing precision parts ranging from 0.5 to 3 mm in diameter and ranging to 40 mm (1.57") in length. Main and back-spindle speeds range from 200 to 20,000 rpm. Rapid traverse rate is 20 m/min (787 ipm). A symmetrical construction reduces thermal displacement, and the standard configuration includes two cross-rotary tools for Y-axis milling. The gripping force of the chucks can be adjusted with an air-pressure-reducing valve so that thin pipe material can be clamped gently. Force is transmitted directly from an air cylinder to a collet chuck. The lathe is equipped with a dedicated bar feed designed for small-diameter bar and a FANUC 32i-A control.

 

The lathe can accommodate as many as 14 tools. The tool-height compensation function calculates the center height difference and automatically sets it in the turret data when actual OD values for two locations after cutting are entered. A tool-height displacement compensation system that automatically applies offsets also is available.
