Overview
The Nexturn NA32-II is a CNC multi-spindle automatic turning machine built by Nexturn, a South Korean manufacturer known for Swiss-type and multi-spindle CNC lathes aimed at precision parts production. The NA32-II is Nexturn's multi-spindle platform targeting the same high-volume bar turning market dominated by European multi-spindle brands, offering buyers an Asian-manufactured alternative with competitive pricing and modern CNC architecture.
The NA32-II is configured as a multi-spindle automatic with simultaneous machining at each spindle position, enabling throughput that single-spindle turning centers cannot approach for high-volume applications. The machine handles bar stock up to 32 mm in diameter, which covers the predominant range of turned parts in automotive, hydraulics, electronics hardware, and medical device manufacturing where multi-spindle automatics are deployed. Multiple spindle positions allow overlapping rough turning, grooving, drilling, threading, and cutoff operations in a single continuous cycle.
Nexturn equips the NA32-II with CNC servo-driven slides throughout, reflecting the industry shift away from mechanical cam actuation toward programmable servo motion. This architecture allows the machine to be reprogrammed for new part families without cam replacement, significantly improving flexibility for shops that mix production campaigns across multiple part numbers. The CNC control accepts standard G-code programs with multi-channel execution managing simultaneous axis motion at all spindle positions.
As a Korean-built machine, the NA32-II occupies a pricing position below comparable European multi-spindle automatics while targeting the same market segments. Nexturn has established a distribution network across Asia, North America, and Europe for the NA series, and the company's existing presence in the Swiss-type lathe market provides a service infrastructure that extends to the NA32-II. Buyers already running Nexturn Swiss-type machines benefit from shared service relationships.
New NA32-II machines are typically priced in the $700,000–$1,100,000 range, reflecting the Korean manufacturer's cost position relative to German and Swiss brands. The machine is positioned as a practical entry point for shops moving into multi-spindle production or expanding capacity at lower capital cost than European alternatives.

Strengths & Limitations
Strengths
- Competitive pricing below European multi-spindle brands makes multi-spindle production more accessible for shops with tighter capital budgets
- CNC servo-driven slides enable rapid changeover through program download rather than mechanical cam replacement
- 32 mm bar capacity covers the mainstream range of automotive, hydraulic, and precision hardware turned parts
- Nexturn's existing service network for Swiss-type lathes provides dealer and support infrastructure that extends to the NA32-II
- Fanuc or Mitsubishi CNC with familiar control interfaces reduces operator training requirements for shops already using these platforms
Limitations
- Korean multi-spindle automatics have less established reputation in heavy-duty automotive production compared to Schütte, Index, or TAJMAC European brands
- Multi-channel CNC programming for multi-spindle automatics requires specialized expertise that may not be readily available in all markets
- Resale value and market liquidity for Korean multi-spindle automatics is generally lower than established European brands

Frequently Asked Questions
01
Nexturn's Swiss-type lathes (BN and SA series) are single-spindle sliding headstock machines suited for long, slender precision parts. The NA32-II is a multi-spindle automatic optimized for high-volume production of shorter, chucked or bar-fed parts where simultaneous multi-position machining delivers higher throughput than any single-spindle machine.
02
The NA32-II is available with Fanuc or Mitsubishi CNC in multi-channel configuration. Multi-channel CNC is required for multi-spindle automatics to coordinate simultaneous independent axis motion at each spindle position.
03
The NA32-II handles free-machining steel, stainless steel, aluminum, brass, copper, and engineering plastics. Like all multi-spindle automatics, it is optimized for bar-fed production where material machinability supports the rapid cycle times that justify multi-spindle investment.
04
Yes. The NA32-II is compatible with standard magazine bar feed systems that feed bar stock automatically, which is essential for unattended production runs. Part collection and conveyors can also be integrated for lights-out production.
05
The effective cycle time per part equals the single longest station cycle time divided by the number of simultaneous operations rather than the sum of all operations. For a six-station multi-spindle machine, this can yield 4–6x throughput versus a single-spindle turning center running the same part with the same cutting conditions.
