Overview

The DN Solutions DNM 6700 4TH combines the large-envelope DNM 6700 platform with an integrated 4th-axis rotary table for multi-face machining of bigger parts. Axis travels of 1,300 x 670 x 625 mm (51 x 26 x 25 in) give you substantially more room than the 5700-class machines, and the 625 mm Z-axis opens up deep-cavity and tall-part work that smaller VMCs can't touch.

The spindle pushes 18.5 kW (25 hp) and 117.8 Nm through an ISO 40 taper at 8,000 RPM — the same proven powertrain running across the entire DNM family. The box-way construction on this larger frame delivers rigidity that matters even more when you're cutting at extended reaches. Rapid traverse rates of 36/36/30 m/min on X/Y/Z keep cycle times competitive despite the larger travel envelope.

The table measures 1,500 x 670 mm with a 1,300 kg load capacity. That's a serious platform for heavy fixtures with rotary work — you can load up a tombstone or multi-sided fixture and machine four faces without unclamping. At 8,500 kg machine weight, vibration damping during interrupted cuts and directional changes is noticeably better than lighter 40-taper VMCs.

The integrated 4th axis runs directly through the Fanuc 0i-Plus control, supporting both indexing and simultaneous 4-axis interpolation. For shops producing mid-to-large components that need machining on multiple faces — hydraulic manifolds, pump housings, large brackets — the DNM 6700 4TH eliminates the multiple-setup workflow that kills throughput and introduces re-fixturing errors.

Strengths & Limitations

Strengths

Integrated 4th axis with 1,300 kg table capacity handles heavy tombstone and multi-sided fixture setups for multi-face machining
625 mm Z-axis travel provides deep reach for tall parts and cavity work that the 5700-class machines can't accommodate
1,300 mm X-axis travel covers larger parts while the 670 mm Y-axis adds cross-travel for wider workpieces
8,500 kg machine weight provides excellent vibration damping during aggressive 4-axis cutting with directional force changes
Box-way construction on this larger frame maintains rigidity at full reach — no accuracy loss at travel extremes
Fanuc 0i-Plus simultaneous 4-axis interpolation enables complex contoured toolpaths, not just indexing

Limitations

8,000 RPM spindle limits high-speed aluminum work — consider the DNM 6700 with an aftermarket high-speed rotary if you need both speed and 4th axis
Larger footprint than the 5700-class 4TH models requires more floor space commitment
Higher price point versus the DNM 5700 L 4TH may be hard to justify if the extra Y and Z travel aren't needed
30-tool magazine fills up fast with 4-axis work — 40- or 60-tool upgrade is often necessary

Best For

Aerospace manufacturers machining large aluminum and titanium brackets requiring multi-face access in a single setup Hydraulic and pneumatic component shops producing manifold blocks and valve bodies on tombstone fixtures Job shops that need a large-envelope 4th-axis VMC for prototype and low-volume multi-face work Pump and compressor manufacturers machining housings and covers that need features on multiple faces Shops replacing horizontal machining centers with a lower-cost 4th-axis VMC for similar multi-face capability

Frequently Asked Questions

01 What does a DN Solutions DNM 6700 4TH cost?

New machines run $130,000-$180,000 depending on spindle option, tool changer capacity, and accessories. The integrated 4th axis adds roughly $25,000-$35,000 over a base DNM 6700. For shops considering an HMC for multi-face work, the 6700 4TH can be a cost-effective alternative at about half the price.

02 How does the DNM 6700 4TH compare to a horizontal machining center?

An HMC provides better chip evacuation, dual-pallet automation, and true tombstone machining with gravity assist. The DNM 6700 4TH costs roughly half as much, has a smaller footprint, and still delivers 4-face access. For lower volumes and tighter budgets, the 4th-axis VMC is a practical alternative.

03 What's the difference between the DNM 6700 4TH and DNM 5700 L 4TH?

The 6700 4TH has more Y-travel (670 vs 570 mm), more Z-travel (625 vs 510 mm), a larger table (1,500 x 670 vs 1,500 x 570 mm), and higher load capacity (1,300 vs 1,000 kg). It weighs 1,500 kg more. Choose the 6700 when you need the extra Y and Z reach; the 5700 L covers most mid-size work at a lower price.

04 Can I upgrade the tool magazine?

Yes. The DNM 6700 platform supports 40- and 60-tool magazine options. For 4-axis work with multiple operations per face, the 60-tool option is strongly recommended to avoid mid-cycle tool changes that kill productivity.
