Matsuura H.Plus-630

The Matsuura H.Plus-630 is a 630 mm pallet horizontal machining center designed for shops that need a bigger work envelope than 500 mm pallet machines can provide. Matsuura has been building HMCs in Fukui, Japan since the early 1980s, and the H.Plus series is their workhorse production platform. The 630 sits in the lineup between the H.Plus-405 and H.Plus-800, covering the medium-to-large part range that dominates in automotive, aerospace, and general industrial production.

The work envelope is generous: 1,050 x 920 x 990 mm (41.3 x 36.2 x 39.0 in) of travel, with parts up to 1,050 mm diameter and 1,000 mm height on the 630 x 630 mm pallet. Maximum pallet load is 1,200 kg (2,640 lbs), so heavy fixtures and multi-part tombstones are well within its capability. Rapid traverse hits 50 m/min (1,968 ipm) on all axes, and spindle acceleration from 0 to 12,000 RPM takes just 4 seconds.

The standard spindle is a BT50 Big Plus running at 12,000 RPM with a 40 hp motor and 700 Nm of high-torque capability. That torque number is exceptional for a 630 mm class machine and means you can push large face mills and heavy boring bars without slowing down. Optional spindle configurations include a 20,000 RPM high-speed spindle (108.4 Nm) for aluminum work and a 15,000 RPM high-torque spindle (350 Nm) for heavy-duty steel and cast iron. The 60-tool ATC is standard, expandable to a massive 330 tools with the matrix-type magazine.

The B-axis rotary indexing table uses a direct-drive motor with 100 RPM maximum feed rate, providing fast, backlash-free indexing. Pallet storage is expandable to 6 pallets with the floor pallet system for extended unmanned operation. The H.Plus-630 competes with the Makino A81nx, Okuma MB-8000H, and Mazak HCN-6800. Matsuura's strength is in unmanned production — the combination of up to 330 tools and 6 pallets creates a genuine FMS-capable cell from a single machine.
