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.

UV laser micromachining makes it possible to drill holes that are not visible to the human eye—until they are meant to be seen, that is.
