Overview

The Citizen Cincom R01-VI is a micro Swiss-type lathe: a sliding-headstock automatic built for parts no larger than 1 mm dia., machined in lengths of 20 mm with either the fixed or the rotary guide bushing. Main and back spindles both run to max. 20,000 rpm, which is what a 1 mm diameter needs to reach a usable cutting speed. Its sister model, the Cincom R04-VI, has the same tooling rows, spindle speeds and weight; what separates them is the work size.

The Cincom R04-VI machines up to 4 mm dia. and gives 40 mm of length with the fixed guide bushing and 30 mm with the rotary one. The R01-VI is limited to 1 mm dia. and 20 mm in either mode, and its back spindle chucks 1 mm dia. against 4 mm dia. on the Cincom R04-VI. A buyer whose parts are all sub-millimetre gets a machine scaled to that size; anything over 1 mm belongs on the R04-VI.

The tooling is compact. 17 tools can be mounted, turning tools are 8 mm Sq. and the sleeves 15.875 mm dia. Gang rotary tools run to max. 8,000 rpm for 2 mm dia. drilling and M2 tapping, from a 0.1 kW tool spindle drive. The back spindle holds the part with up to 10 mm protruding. X1 rapids at 30 m/min.

The drives are small by any lathe standard: 0.5/0.75 kW for the main spindle, the same for the back spindle, and 0.06 kW for the coolant pump. Power requirement is 3.4 kVA, with 1.6 kVA average under load. The machine weighs 1,100 kg and puts the spindle centre at 1,000 mm.

Strengths & Limitations

Strengths

Main and back spindles both reach max. 20,000 rpm for cutting speed on 1 mm dia. work
Machines 20 mm of length with either the fixed or the rotary guide bushing
17 tools on a compact gang layout with 8 mm Sq. turning tools
Gang rotary tools to max. 8,000 rpm for 2 mm dia. drilling and M2 tapping
Low running power: 3.4 kVA requirement and 1.6 kVA average under load

Limitations

Limited to 1 mm dia. work; the Cincom R04-VI is needed for anything up to 4 mm dia.
Only 20 mm of machining length, half the 40 mm of the Cincom R04-VI with a fixed guide bushing
Back spindle protrusion is limited to 10 mm
0.1 kW tool spindle drive restricts driven-tool work to light drilling and M2 threads

Best For

Sub-millimetre turned pins and shafts up to 1 mm dia. Micro parts machined in 20 mm lengths Fine cross holes up to 2 mm dia. and M2 threads Shops adding a dedicated micro-part machine with a small power supply

Frequently Asked Questions

01 What is the difference between the Cincom R01-VI and the Cincom R04-VI?

Work size. The Cincom R01-VI machines up to 1 mm dia. with 20 mm of length from either guide bushing, and its back spindle chucks 1 mm dia. The Cincom R04-VI machines up to 4 mm dia., with 40 mm of length on the fixed guide bushing and 30 mm on the rotary one, and a 4 mm dia. back chuck. Spindle speeds, the 17-tool layout and the 1,100 kg weight are the same.

02 Why does the R01-VI need 20,000 rpm?

On a 1 mm dia. part the surface speed at any given rpm is tiny, so a micro lathe needs very high spindle speeds to cut properly. The R01-VI gives max. 20,000 rpm on both the main and the back spindle, each driven by a 0.5/0.75 kW motor.

03 Can the R01-VI use a rotary guide bushing?

Yes. The table lists the maximum machining length as 20 mm with the fixed guide bushing and 20 mm with the rotary guide bushing, so on this model the choice does not cost machining length.

04 What power supply does the Cincom R01-VI need?

The power requirement is 3.4 kVA and the average during load operation 1.6 kVA. The motors are 0.5/0.75 kW for each spindle, 0.1 kW for the tool spindle and 0.06 kW for the coolant pump. The machine weighs 1,100 kg.
