2015 Akari Seiki HS-450j CNC Horizontal Machining Center with 2-Pallet Changer

The Akari Seiki HS-450j is a 40-taper CNC horizontal machining center built by Averex Automation of Taichung, Taiwan, a builder known for rigid, practical HMCs that suit job shops and production cells alike. This 2015 machine provides X, Y and Z travels of 25.2 x 24 x 26.8 inches and is configured with a two-pallet automatic pallet changer, so one pallet can be loaded while the other is in the work zone. Each pallet sits on a full continuous 4th-axis B-axis rotary, allowing multi-sided and contouring work in one clamping on fixtures and tombstones. The spindle is rated at 15,000 RPM with a 30 HP motor and a CAT 40 Big Plus dual-contact taper for stiffer tool holding, higher accuracy and better surface finishes. A 60-tool automatic tool changer supports high-mix work with sister tooling. The machine runs an Averex-Fanuc MPro I CNC control, a Fanuc-based platform familiar to most programmers and operators, with standard G-code programming. High pressure through-spindle coolant at 300 PSI aids chip evacuation in drilling and deep pocketing, and chips are handled by a chip conveyor with chip augers. Electrical service is 220V, 3-phase, and the data plate lists a machine weight of 24,130 lbs.

The HS-450j follows the earlier HS-450i in the same HS-450 HMC family and keeps that model's full 25.2 x 24 x 26.8 inch work envelope and 15,000 RPM 40-taper spindle. What sets this unit apart is a later build with a production-oriented package already installed: a 60-tool magazine in place of the standard 40-tool configuration, a full contouring 4th axis rather than a basic indexer, 300 PSI through-spindle coolant and a Big Plus spindle interface. For a shop stepping up from vertical machining centers, that means less fixture shuffling, fewer setups per part and more spindle uptime from the pallet changer, in a machine sized to fit a typical production floor.
