Overview

The DN Solutions DNM 6700 L 4TH is the biggest integrated 4th-axis machine in the DNM lineup, combining the extended 1,500 mm X-travel of the 6700 L with a factory-integrated rotary table. You're looking at 1,500 x 670 x 625 mm (59 x 26 x 25 in) of linear travel plus continuous rotary capability — that's enough envelope for large multi-face parts that most 4th-axis VMCs can't accommodate.

The spindle delivers 18.5 kW (25 hp) and 117.8 Nm through an ISO 40 taper at 8,000 RPM. Rapid traverse runs 36/36/30 m/min on X/Y/Z. The 1,600 x 670 mm table carries 1,300 kg, giving you the capacity for heavy tombstone fixtures loaded with multiple parts. Box-way construction keeps everything stable across the full travel range, which is critical on a machine this size where the spindle operates at significant distances from the column.

The integrated 4th axis is controlled directly through the Fanuc 0i-Plus, supporting simultaneous 4-axis interpolation as well as simple indexed positioning. This means you can program complex contoured toolpaths across rotational and linear axes simultaneously, or just use indexing to access multiple flat faces on a workpiece. At 9,000 kg machine weight, vibration damping is excellent even during interrupted 4-axis cuts where force direction changes constantly.

This machine targets shops that are doing large multi-face work and want to avoid the cost and complexity of a horizontal machining center. Long manifold blocks, large aerospace brackets, pump housings, and multi-station tombstone work all play to the DNM 6700 L 4TH's strengths. The extended X-travel means you can fixture bigger parts or more parts per cycle than the standard 6700 4TH.

Strengths & Limitations

Strengths

Largest integrated 4th-axis envelope in the DNM family — 1,500 mm X-travel with 670 mm Y and 625 mm Z for oversized multi-face parts
1,300 kg table load handles heavy tombstone fixtures loaded with multiple workpieces for high-throughput production
Factory-integrated 4th axis eliminates compatibility headaches and provides tighter accuracy than aftermarket rotary tables
9,000 kg machine weight ensures vibration damping across the full extended travel range during 4-axis cutting
Simultaneous 4-axis interpolation through Fanuc 0i-Plus enables complex contoured toolpaths, not just indexing
Box-way construction maintains rigidity at extended X-axis positions where long-travel linear-guide machines lose stiffness

Limitations

Highest price point in the DNM 4TH family — make sure you need both the extended travel and 4th axis to justify the investment
8,000 RPM spindle is conservative for high-speed aluminum work on a machine this capable
Large footprint and 9,000 kg weight demand serious floor preparation and limit future relocation
30-tool standard magazine fills up quickly during multi-face 4-axis work — budget for the 60-tool upgrade

Best For

Aerospace production shops machining large brackets, housings, and structural components needing 4-face access in a single setup Hydraulic equipment manufacturers producing oversized manifold blocks and valve bodies on tombstone fixtures Job shops replacing HMC capacity with a lower-cost 4th-axis VMC for multi-face work on large parts Energy sector shops machining pump housings, turbine components, and large valve bodies Mold shops needing 4th-axis capability for large mold components with features on multiple faces

Frequently Asked Questions

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

Expect $140,000-$195,000 new for a fully equipped DNM 6700 L 4TH. That's roughly $30,000-$40,000 more than the base DNM 6700 L for the integrated 4th axis. Still significantly less than a comparable horizontal machining center, which would run $250,000+.

02 Is the DNM 6700 L 4TH a replacement for a horizontal machining center?

For many applications, yes. It provides 4-face access at roughly half the cost of an HMC. However, HMCs still win on chip evacuation (gravity pulls chips away from the cut), pallet automation, and sustained heavy production throughput. The 6700 L 4TH is ideal for lower volumes and tighter budgets.

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

The L variant extends X-travel from 1,300 to 1,500 mm and table length from 1,500 to 1,600 mm. Both share the same Y (670 mm), Z (625 mm), and 1,300 kg table capacity. The L costs more and has a larger footprint but handles longer parts and wider multi-station fixture setups.

04 Can I run unattended with this machine?

With a properly set up 4th-axis tombstone fixture, tool breakage detection, and coolant management, you can run extended unattended cycles. Adding a 60-tool magazine and probe system further extends autonomous run time. The Fanuc 0i-Plus supports macro-based monitoring and conditional tool change logic.
