Overview
The DMG Mori INH 63 is a heavy-duty horizontal machining center built for shops that need maximum metal removal rates on large, demanding workpieces. With 1,050 x 1,100 x 1,050 mm (41.3 x 43.3 x 41.3 in) of travel and a 630 x 630 mm (24.8 x 24.8 in) pallet, it handles tombstone setups and large castings that exceed the capacity of 500mm-class HMCs.
The powerMASTER spindle is the INH 63 centerpiece: 85 kW (114 hp) with torque ranging from 808 Nm (596 ft-lb) at 1,000 RPM to 1,414 Nm (1,043 ft-lb) at low speed, through a geared head with CAT 50 (BT 50) taper. Maximum speed is 6,000 RPM, with an 8,000 RPM option for shops doing lighter cuts at higher surface speeds.
Rapid traverse hits 60 m/min (2,362 ipm) on roller guides, and the 2-pallet changer is standard. Tool storage starts at 60 positions with expansion to 120 or 240 for high-mix production cells. The B-axis rotary table indexes in 0.001-degree increments for full 4th-axis capability.
At approximately 25,000 kg (55,116 lb), the INH 63 is built for serious industrial work. The thermally symmetric construction with active cooling throughout maintains positioning accuracy of ±0.004 mm across the full travel volume. The machine runs on SIEMENS 840D sl or FANUC 31i-B control with CELOS X interface.
New INH 63 machines price between $425,000 and $595,000 depending on spindle choice, control, and automation options. The INH 63 competes directly with the Mazak HCN-6800, Okuma MB-8000H, and Makino A81nx. Specs sourced from DMG Mori published data and dealer references.

Strengths & Limitations
Strengths
- 85 kW powerMASTER spindle with up to 1,414 Nm of torque makes this one of the most powerful 630mm-class HMCs available
- 1,050 mm travel in X and Z with 1,100 mm in Y provides a generous work envelope for large tombstone and fixture setups
- 2-pallet changer standard keeps spindle utilization high during loading and unloading operations
- 60-tool standard with expansion to 240 supports high-mix production without constant manual tool management
- At 25,000 kg, the machine provides exceptional rigidity and thermal mass for stable heavy-duty cutting
- Choice of SIEMENS or FANUC control accommodates different shop environments and operator skill sets
Limitations
- Starting at $425K, the INH 63 represents a major capital commitment that requires consistent utilization to justify
- 6,000 RPM standard spindle speed limits surface speed on smaller-diameter aluminum work; the 8K option helps but adds cost
- 25,000 kg machine weight requires substantial foundation preparation and may limit placement in some facilities
- DMG Mori service contracts and parts costs are among the highest in the industry, affecting long-term TCO
- 1,500 kg pallet load may be limiting for very heavy tombstone setups compared to larger 800mm-class HMCs

Frequently Asked Questions
01
New INH 63 machines start around $425,000 for a base FANUC configuration. With SIEMENS control, expanded tool magazine (120 or 240 tools), 8,000 RPM spindle, and automation integration, expect $500,000-$595,000. Additional pallet systems add $100,000-$300,000+ depending on configuration.
02
Both are premium 630mm-class HMCs. The INH 63 offers more spindle power (85 vs 37 kW standard) and torque, making it the better choice for heavy roughing. The Mazak counters with PALLETECH automation integration and higher standard spindle speed (12,000 vs 6,000 RPM on the CAT 40 variant). For heavy cutting, the INH 63 wins. For high-speed production with automation, the Mazak has the edge.
03
The powerMASTER is DMG Mori high-performance geared spindle designed for maximum torque output. With 85 kW and up to 1,414 Nm, it delivers the cutting force needed for aggressive roughing in steel, cast iron, titanium, and Inconel. The geared head provides constant torque across a wide RPM range, unlike direct-drive spindles that lose torque at low speeds.
04
Yes, with proper setup. The 2-pallet changer enables one-pallet-ahead operation. Tool life management, tool breakage detection, and the 60-240 tool magazine support extended unattended runs. For full lights-out capability across a shift, add a linear pallet pool system, which DMG Mori offers as an integrated automation option.
05
At 25,000 kg, the INH 63 requires a reinforced concrete pad minimum 250 mm (10 in) thick, poured on compacted subgrade. An isolated foundation is recommended to prevent vibration transmission. Consult DMG Mori installation engineering for site-specific requirements.
