Overview

The DN Solutions XC 4000-2SP is a dual-spindle vertical machining center engineered for high-volume production environments where throughput and cost-per-part are the driving metrics. Equipped with two independent 12,000 RPM directly-connected spindles, the XC 4000-2SP effectively doubles output compared to single-spindle VMCs—machining two identical parts simultaneously from the same program. This makes it an exceptionally cost-effective solution for automotive, consumer electronics, and other industries producing medium-to-high volumes of small-to-medium parts.

Each spindle operates over 630 x 400 x 360 mm (25 x 16 x 14 in) of travel, with independent Z-axis control allowing for slight differences in tool length or part height. The mineral cast bed provides superior vibration damping compared to conventional cast iron, resulting in better surface finishes and longer tool life—critical when running two spindles at production pace. The 2x24 tool magazine provides 24 tools per spindle with 3.8-second chip-to-chip tool change time. Rapid traverse of 70 m/min (2,756 ipm) across all axes keeps non-cutting time minimal.

The 790 x 300 mm (31 x 12 in) table supports workpieces up to 2,200 kg (441 lb per station), and the machine's compact 6,156 x 2,230 x 3,200 mm footprint keeps floor space usage efficient for the doubled output it delivers. At 12,000 kg (26,455 lb), the XC 4000-2SP is built for continuous production duty. The FANUC 0i-Plus control manages both spindles seamlessly. For shops producing identical parts in volume, the XC 4000-2SP delivers roughly twice the output of a conventional VMC without doubling floor space, operators, or investment.

Strengths & Limitations

Strengths

Dual-spindle design doubles output compared to single-spindle VMCs without doubling floor space or operator count
70 m/min rapid traverse across all axes is exceptionally fast, minimizing non-cutting time in production cycles
Mineral cast bed provides 6-10x better vibration damping than cast iron for superior surface finish and tool life
12,000 RPM directly-connected spindles deliver smooth, vibration-free cutting for consistent part quality across both stations
Cost-per-part advantage is significant in medium-to-high volume production compared to running two separate machines

Limitations

360 mm Z-travel limits part height—not suitable for tall workpieces or deep-cavity mold work
Both spindles run the same program, so the machine is optimized for identical parts only—not mixed production
Higher initial investment than a single-spindle VMC, though ROI is typically strong in production environments
400 mm Y-travel constrains part width—designed for smaller automotive and electronics components

Best For

Automotive suppliers producing high volumes of identical small-to-medium parts where cost-per-part drives competitiveness Consumer electronics manufacturers machining housings, brackets, and enclosures in aluminum at production volume Contract manufacturers with stable, high-volume contracts that justify dual-spindle investment over single-spindle flexibility Shops looking to double output without doubling floor space, operators, or utility connections

Frequently Asked Questions

01 What does a DN Solutions XC 4000-2SP cost?

A new DN Solutions XC 4000-2SP typically runs between $280,000 and $400,000 depending on configuration and automation options. The base machine starts around $280,000-$320,000. Adding through-spindle coolant, probing for both spindles, and chip management systems pushes pricing to $340,000-$370,000. With automation integration (robot loading, conveyor systems), the total cell cost can reach $400,000 or more. The investment is typically justified by the near-doubling of output versus two separate single-spindle machines.

02 Can the two spindles run different programs?

The XC 4000-2SP is designed to run the same program on both spindles simultaneously, producing two identical parts per cycle. The Z-axes have independent control to compensate for minor tool length differences, but the X and Y axes are shared. This design is intentional—it maximizes production efficiency for identical parts. Shops needing to run different programs simultaneously should consider two separate single-spindle machines.

03 What is a mineral cast bed and why does it matter?

Mineral casting (also called polymer concrete or epoxy granite) is a composite material that provides 6-10 times better vibration damping than traditional cast iron. The XC 4000-2SP uses a mineral cast bed to absorb vibration from two spindles running simultaneously, which is critical for maintaining surface quality and extending tool life. Mineral cast also provides excellent thermal stability, reducing warm-up time and improving dimensional consistency across production runs.

04 How does the XC 4000-2SP compare to buying two separate VMCs?

The XC 4000-2SP typically costs 40-50% more than a single comparable VMC but delivers nearly twice the output. Compared to buying two separate machines, the 2SP saves roughly 30-40% on total investment, requires one operator instead of two, uses roughly 60% of the floor space, and consumes less total power. The trade-off is flexibility—two separate machines can run different parts and provide redundancy if one goes down.
