HMC Targets Less Setup Time, Energy Consumption

DMG MORI USA introduces the INH 63 horizontal machining center (HMC), a more sustainable and efficient CNC option when designing demanding components in tool and moldmaking industries. The INH 63, capable of handling 630-mm pallets and made for large workpieces up to 42" in diameter, enables high process integration, can be automated flexibly and is available in a five-axis version.

Features useful for mold builders include the HMC’s symmetrical, FEM-optimized structure and twin ball screw “DCG” on all linear axes, ensuring stability for dynamic machining. Improved cooling of all motors, ball screws and motor mounts is also noted. The INH 63 is characterized by its wide axis range — ensuring efficient chip removal. A 12,000-rpm powerMaster spindle comes as standard but spindles up to 16,000 rpm are optional. 

The technology’s five-axis version highlights a swivel rotary table with large bearings and two high-performance torque motors as the A-axis. This eliminates backlash and ensures maximum precision. An ergonomically accessible work area is large enough to offer sufficient space even for overhanging tools. With the ability to machine negative angles, the INH 63 also meet an essential requirement in die and moldmaking. The table can be fully swiveled through 180 degrees, enabling “upside down” machining capabilities. 

DMG MORI notes the INH 63’s integration of different manufacturing processes in one machine — turning, milling and other processes such as measuring or gear cutting — reducing setup times. It can also work unattended for up to three shifts; automated tool and pallet handling and the intelligent Cell Controler LPS 4 master computer increases productive spindle hours from 2,000 to more than 6,000 per year compared to the standalone installation, the company claims. The equipment also allows integration into holistic production systems. A GreenMode reduced energy consumption by more than 30%.
