About this machine
The Citizen K16 VII is a used CNC sliding-head lathe — sometimes referred to as a Swiss-type lathe or Swiss screw machine — a precision turning machine designed to produce small, complex, tight-tolerance components from bar stock. Citizen is a well-established Japanese manufacturer with a long history of producing high-precision sliding-head and fixed-head CNC lathes, widely used in the medical device, watchmaking, aerospace, automotive, and electronics industries.
This machine is configured with seven axes and two spindles, giving it the ability to perform simultaneous front and back-working operations in a single setup. The main spindle accepts bar stock up to 16 mm in diameter and runs to 15,000 rpm, driven by a 3.7 kW spindle motor, with a minimum C-axis resolution of 0.001° for precise angular positioning. Maximum workpiece length is 200 mm. The sub-spindle handles secondary operations, running to 10,000 rpm with a 1.1 kW drive motor, an 80 mm Z-axis travel, and the same 0.001° C-axis resolution as the main spindle.
The tool turret carries ten stations, four of which are live, with driven tooling reaching 6,000 rpm. In addition, a four-position front tooling unit and a three-position sub-operation tooling unit further expand the machine's multi-task capability. The machine is equipped with a guide bushing, which is a defining feature of sliding-head turning, providing continuous bar support close to the cutting zone to maintain dimensional accuracy on slender workpieces.
Control is handled by a Fanuc 31i CNC unit, one of Fanuc's high-specification multi-axis controllers well suited to the demands of complex sliding-head turning. The electrical supply requirement is 200 V with a total power consumption of 8 kW, and an electrical transformer is included with the machine. The machine weighs 2,050 kg, requires a floor footprint of 1,850 × 1,610 mm, and stands 1,050 mm tall.
The package includes a full complement of peripheral equipment: a coolant tank, parts removal system, parts ejector, and an IEMCA BOSS 332r bar feeder, which is a purpose-built automatic bar loading system compatible with the machine's bar capacity. This is a complete, ready-to-integrate turning cell dating from 2005, currently located in Italy.
