Overview

The DN Solutions VCF 850 LSR II combines the long 3,000 mm X travel of the VCF 850 L II with an integrated rotary table or sub-spindle configuration (the SR designation). This gives shops working on large parts the ability to add indexing or multi-face machining without switching to a horizontal platform. It's the most versatile member of the VCF 850 II family.

The core specs match the L II exactly: 3,000 x 850 x 800 mm travels, 12,000 RPM spindle with 26 kW (34.8 hp) and 207 Nm (152.7 ft-lb) of torque, 40 m/min rapids on all axes, and a 3,500 x 870 mm table rated for 3,500 kg. The machine weighs 24,000 kg (52,911 lb), identical to the L II, which tells you the additional SR capability is integrated without compromising the base machine's rigidity.

What makes the LSR II distinct is its multi-face machining capability. The SR functionality lets you reach features on multiple sides of a workpiece that would require separate setups on a standard VMC. For mold shops, this means machining coolant channels, ejector pin holes, and side features without flipping heavy mold halves. For structural work, it means completing more operations before the part leaves the table.

The 850 mm Y travel and 800 mm Z travel provide the depth and width access that most long-bed VMCs lack. Combined with 3,000 mm of X travel, the envelope covers large die sets, press tools, and structural weldments that would otherwise need a horizontal boring mill.

DN Solutions runs the Fanuc 0i-Plus control with iHMI. The Generation II updates carry over from the rest of the VCF 850 family — improved thermal compensation, updated casting designs, and refined spindle technology. This machine sits at the top of DN Solutions' flatbed VMC range in terms of combined travel, power, and multi-face capability.

Strengths & Limitations

Strengths

Combines 3,000 mm X travel with multi-face machining capability in a single vertical platform
207 Nm spindle torque handles aggressive roughing on large castings and mold components
850 mm Y and 800 mm Z travels provide the depth access that narrower long-bed machines lack
40 m/min rapids on all axes are fast for a 24-ton machine
SR functionality reduces the number of setups required for multi-face large parts
Generation II improvements to thermal compensation and rigidity over the original model

Limitations

Higher price than the standard L II for the added SR capability — evaluate whether you'll use it enough to justify the premium
24,000 kg weight and large footprint require reinforced floors and dedicated shop space
ISO 40 taper feels undersized for the machine's capabilities — BT50 would be more appropriate for heavy-duty work
Multi-face machining complexity requires more programming and setup expertise from operators

Best For

Mold and die shops that need multi-face machining on large mold bases without flipping heavy workpieces Structural component manufacturers needing features on multiple faces of long parts Shops looking to consolidate multi-setup operations on large parts into single-setup cycles Energy and heavy equipment manufacturers processing complex large components Facilities that want large-part VMC capability with indexing without buying a horizontal boring mill

Frequently Asked Questions

01 What does a DN Solutions VCF 850 LSR II cost?

New VCF 850 LSR II machines typically run $340,000-$460,000. The premium over the standard L II ($300-420K) reflects the added SR multi-face machining capability.

02 What does the SR designation mean?

The SR indicates an integrated sub-rotary or swivel capability that enables multi-face machining. This lets you reach features on additional sides of the workpiece without removing it from the table. The exact configuration can vary — check with your DN Solutions distributor for the specific SR implementation.

03 How does it compare to the VCF 850 SR II?

The LSR II has 3,000 mm X travel versus the SR II's 2,000 mm. Both have the same Y/Z travels, spindle, and SR capability. The LSR II weighs 2,000 kg more and needs more floor space. Choose based on whether your parts routinely exceed 2 meters in the longest dimension.

04 Can this replace a horizontal boring mill?

For many applications, yes. The SR capability addresses the main limitation of vertical machines — accessing multiple sides. It won't match a full HBM for very large parts or parts requiring true 4-axis simultaneous machining around the full circumference, but for mold work and structural components, it's a compelling alternative at lower cost.
