Overview

The Citizen Miyano ABX-38 is a 2-spindle, sliding headstock CNC automatic lathe from Citizen's Miyano product line, designed for production turning of bar stock up to 38mm diameter. The ABX series occupies a distinct segment between conventional Swiss-type lathes and standard CNC turning centers: it uses a sliding headstock design inherited from Swiss-type architecture but in a larger, more powerful package suited for the bar sizes and part complexity typical of automotive, hydraulics, and fluid power component manufacturing.

The ABX-38's 2-spindle configuration with main and sub-spindle enables complete part machining—front turning and back-work—in a single cycle without workpiece transfer to a secondary operation. This is the fundamental productivity advantage of the 2-spindle architecture: complete parts exit the machine without additional setups. The 38mm bar capacity covers the diameter range for hydraulic valve bodies, pneumatic fittings, fuel system components, and a broad range of turned parts that are too large for traditional 32mm Swiss-type machines but well suited to bar fed production rather than chuck work.

Citizen's Miyano ABX machines are engineered for high-volume production with rapid cycle times, featuring a slant-bed construction for efficient chip evacuation and rigid tool post mounting for aggressive turning parameters. The machine supports driven tooling (Y-axis milling, drilling) on both main and sub-spindle sides, enabling milled features, cross-holes, flats, and other secondary features to be completed within the primary production cycle. This multi-tasking capability is critical for automotive and hydraulic parts that routinely require both turning and cross-drilled or milled features.

The ABX-38 operates with a FANUC control—a significant differentiator from Citizen's Cincom Swiss line, which uses Mitsubishi Meldas. FANUC familiarity is widespread in CNC shops, reducing programming training requirements and enabling more shops to integrate the ABX-38 into existing FANUC-based programming workflows. This control choice reflects the Miyano line's positioning for the production turning market, which has strong FANUC preference, versus the specialized Swiss-type market served by the Cincom line.

Best For

Automotive component manufacturers producing fuel injector bodies, valve spools, sensor housings, and fittings in the 25-38mm bar range at high volume Hydraulics and pneumatics shops producing valve bodies, manifold ports, and fluid control components requiring both turning and cross-drilling in a single cycle Precision production shops running high-volume orders of complex turned parts where complete-part production in one cycle eliminates secondary operations Shops transitioning from Swiss-type capacity to handle larger 38mm bar diameters while retaining the bar-fed production model they know from Swiss-type machining

Frequently Asked Questions

01 What is the difference between the Miyano ABX-38 and a Cincom Swiss-type lathe?

The Miyano ABX-38 uses a sliding headstock design similar to Swiss-type architecture but targets the 38mm bar range for automotive and industrial production applications. The Cincom line is focused on ultra-precision Swiss work in the 7-32mm range for medical, watchmaking, and electronics markets. The ABX-38 uses a FANUC control (not Meldas), does not offer LFV, and is optimized for production turning speed rather than micron-level precision. They serve different markets with different priorities.

02 Does the ABX-38 require a guide bushing?

The ABX-38 uses a sliding headstock design but operates differently from traditional Swiss-type guide bushing setups. The machine is configured for bar-fed production in its nominal diameter range without the guide bushing precision support that defines true Swiss-type turning. It is best understood as a production turning machine with Swiss-type headstock architecture rather than a Swiss-type automatic in the traditional sense.

03 What does a Citizen Miyano ABX-38 cost?

New ABX-38 pricing typically ranges from $180,000 to $280,000 depending on tooling configuration, driven tool count, and options. The machine competes in the production turning market against multi-spindle gang turning centers and twin-spindle turning centers from other manufacturers.

04 What control does the ABX-38 use?

The ABX-38 uses a FANUC CNC control, which is the most widely known control in the production turning market. This is a deliberate choice by Citizen/Miyano to appeal to the automotive and industrial production shops that make up the ABX's primary market, where FANUC familiarity is nearly universal.

05 Can the ABX-38 run lights-out?

The ABX-38 is well suited to lights-out production in conjunction with a bar feeder. Its 2-spindle, complete-part architecture means parts exit finished without operator intervention between cycles. Chip control management is the primary consideration for lights-out operation; insert selection for the specific workpiece material is important given the absence of LFV.
