What the maker publishes about the current Doosan NHM6300
DN Solutions places the NHM 6300 in its NHM series of mid-to-large horizontal machining centers, aimed at tough, hard-to-cut materials. The X axis moves 41 inch, the Y axis 33 inch and the Z axis 39 inch. Work mounts on a 630 mm pallet that supports up to 2646 lb. DN Solutions lists an automatic pallet changer among its features. The spindle takes ISO #50 tooling and runs to 6000 r/min, with 8000 r/min listed in braces as the alternative. Its 35/22 kW motor produces 1278 ft-lb of torque. A servo-driven automatic tool changer serves 60 tool stations. Rapid traverse is 1181 ipm on every axis. The bed is a one-piece structure. Overall, the machine weighs 45195 lb and occupies 252 inch in length and 155 inch in width, at 138 inch tall.

What fits a Doosan NHM6300
Each of these follows from a published specification above, which is named beside it.
50-taper toolholders
This is a 50-taper spindle — the 7:24 steep taper that CAT-50, BT-50 and DIN 69871 (SK-50) holders all share. They share the taper and nothing else that matters: the retention knob and the flange form differ between those standards, so holders do not swap between them without changing pull studs. Knowing which standard a machine was tooled for is worth doing before the holders are packed.
Derived from Spindle taper: ISO #50
Pallets and fixturing
Fixtures, tombstones and spare pallets are cut for a pallet of this size and do not transfer to another machine. On a horizontal they are a large share of what is being sold, so count them before quoting.
Derived from Pallet size: 630 mm (25 inch)
What to check on a Doosan NHM6300
- Spindle taper. The manufacturer gives a spindle taper of ISO #50. Check it for fretting and that the drawbar holds a tool.
- Axes and way covers. The manufacturer gives X 1050 mm (41 inch), Y 850 mm (33 inch) and Z 1000 mm (39 inch) of travel. Run each axis end to end and check the way covers.
- Rapids and ballscrews. The manufacturer gives a rapid traverse of 30 m/min (1181 ipm). Measure the backlash on each axis.
- Tool changer. The manufacturer gives the tool capacity as 60. Cycle every pocket and watch for a hesitation.
- Pallet changer. The manufacturer gives a pallet size of 630 mm (25 inch). Run a full pallet change, and count the pallets and fixtures that come with the machine.
- Table. The manufacturer gives a table load of 1200 kg (2646 lb). Check the table and its T-slots for damage.
- Rigging and floor. The manufacturer gives a machine weight of 20500 kg (45195 lb), a machine length of 6410 mm (252 inch), a machine width of 3930 mm (155 inch) and a machine height of 3495 mm (138 inch). Confirm the rigging route and the floor will take that.
