Overview

The Citizen Cincom R01 is an ultra-compact sliding headstock CNC automatic lathe designed specifically for micro-precision turned parts with a maximum machining diameter of just 1mm. This is the smallest-capacity machine in the entire Cincom range and one of the smallest Swiss-type lathes produced by any manufacturer worldwide. The R01 exists for one purpose: producing the tiniest precision components—watch parts, miniature medical device pins, micro-electronic contacts, and precision instrument components—at the accuracy levels and surface finishes that only a purpose-built micro Swiss machine can deliver.

The R01's main spindle reaches an impressive 20,000 RPM, delivering the high cutting speeds essential for productive machining at sub-millimeter diameters where surface speed drops dramatically. The back spindle matches at 20,000 RPM for secondary operations, ensuring consistent performance across both ends of the part. Spindle bore is 9mm, sized precisely for the micro bar stock the machine is designed to process. Maximum machining length is 40mm per chucking, which represents a significant length-to-diameter ratio at 1mm diameter. The back spindle accepts workpieces up to 4mm with a 10mm protrusion length.

Despite its micro-scale focus, the R01 packs 17 tool positions including rotary tools at 8,000 RPM for cross-drilling, micro-milling, and feature machining. Maximum front drilling diameter is 3mm with M3 tapping capability, while rotary tools handle up to 2mm drilling and M2 tapping. The back spindle provides 2mm drilling and M2.6 tapping for secondary features. Rapid feed rates reach 30 m/min across all axes, keeping positioning time minimal between operations.

At just 900 kg with a 1,000mm center height, the R01 has the smallest footprint in the Cincom range. Spindle drive power is 0.75/1.1 kW with total power consumption of just 4 kVA—the lowest in the lineup. The machine uses 8mm square turning tools sized for the micro-scale work it performs. For manufacturers in the watch, micro-medical, micro-electronics, and precision instrument industries who need production-grade micro-turning capability, the R01 represents Citizen's most specialized and focused sliding headstock platform.

Frequently Asked Questions

01 What does a Citizen Cincom R01 cost?

A new Citizen Cincom R01 typically runs $80,000-$150,000 depending on options and configuration. Despite its small size, the R01 commands a meaningful price due to the precision engineering required for micro-scale machining. Used R01 machines are rare on the secondary market due to the specialized nature of the applications they serve.

02 What is the difference between the R01 and R04?

The primary difference is bar capacity: the R01 handles parts up to 1mm diameter, while the R04 extends to 4mm. They share the same machine platform, 20,000 RPM spindles, 17 tool positions, and 900 kg footprint. The R04 is significantly more versatile for general micro-machining, while the R01 is specialized for the smallest sub-1mm components that require dedicated micro-scale fixturing and tooling.

03 What materials can the R01 machine?

The R01 handles all common Swiss-type materials at micro scale: brass, aluminum, free-machining steels, stainless steel (304, 316, 17-4PH), titanium, precious metals (gold, platinum), and engineering plastics. At sub-1mm diameters, material selection often matters less than tooling quality and machine rigidity. Precious metals are common in watch and jewelry applications.

04 Can the R01 run unattended?

Yes, with appropriate micro bar feeding equipment. The R01 can sustain unattended production runs with a compatible bar feeder, but micro-machining generally requires more frequent quality checks and tool monitoring than larger-scale Swiss turning due to the sensitivity of micro tools to wear and breakage.

05 What bar feeder works with the R01?

The R01 requires a micro-format bar feeder designed for sub-1mm bar stock. Standard Swiss bar feeders cannot handle material this small. Specialized micro bar feeders from manufacturers like LNS and IEMCA offer models designed for ultra-small diameter stock, though the selection is more limited than for standard Swiss bar sizes.

06 How does the R01 compare to micro-EDM for tiny parts?

The R01 and micro-EDM serve different applications. The R01 excels at producing rotational micro parts (pins, shafts, contacts) at production rates, while micro-EDM handles non-rotational features and ultra-hard materials. For round parts under 1mm, the R01 is significantly faster and more cost-effective. Many micro-manufacturing facilities use both technologies—Swiss turning for round parts and EDM for non-round features and hardened materials.
