Overview
The Citizen Cincom B12E-II is a compact, entry-level sliding headstock CNC automatic lathe built for high-speed production of small precision turned parts up to 12mm in diameter. The II designation indicates a streamlined configuration with 12 tool positions, making this the most basic and affordable machine in the B12E family. Without a back spindle and with a focused tooling layout, the B12E-II prioritizes speed, reliability, minimal footprint, and the lowest possible entry cost into Citizen Swiss-type production.
The main spindle reaches 12,000 RPM (8,000 RPM in R.G.B. guide-bushless mode) with 2.2/3.7 kW of power. Maximum machining length is 135mm per chucking with the guide bushing, or 60mm in guide-bushless R.G.B. configuration. The R.G.B. (Removable Guide Bushing) option allows the B12E-II to run with or without a guide bushing, reducing bar remnant waste on shorter parts while maintaining guide bushing support for longer, slender workpieces.
With 12 tool positions and rapid feed rates of 21 m/min on X/Y axes and 15 m/min on Z, the B12E-II handles straightforward turned parts efficiently. This single-spindle machine has no back spindle, so parts requiring secondary operations must be handled separately. The machine weighs just 1,100 kg with 3.3 kVA rated power consumption (2.5 kVA average).
For shops entering Swiss-type turning or running high volumes of simple round parts in brass, aluminum, free-machining steel, or mild stainless, the B12E-II delivers genuine Citizen build quality at the lowest Cincom cost point.
