Matsuura CUBLEX-63

The Matsuura CUBLEX-63 is the large member of the CUBLEX line: a 5-axis machining center with a 630 mm (24.8 in) table whose C-axis also turns, at up to 800 RPM on a direct drive with continuous 360° rotation. Travels are 760 mm (29.9 in) in X, 845 mm (33.3 in) in Y and 660 mm (26.0 in) in Z. Y is the longest of the three and exceeds the table diameter, which gives the tool room to reach across the full width of a large round part.

The work envelope is Ø 630 × H 450 mm (Ø 24.80 × H 17.71 in), and the table is rated for 300 kg (661 lb) per pallet. That load is the figure to check first. A steel part that fills most of the envelope, plus its fixture, can approach 300 kg, so heavy forgings and castings need weighing before they are quoted on this machine.

The spindle is BT50 as standard, with HSK-A63 and HSK-A100 as options. The magazine holds 60 tools as standard and a matrix magazine takes it to 200+. The table lists no spindle speed, power or torque for this model, so those numbers have to come from the quotation, and they matter: a BT50 spindle points to heavy milling, while turning a Ø 630 mm part puts large loads on the C-axis drive.

Against the CUBLEX-35, this machine gives up turning speed for size. The CUBLEX-35 turns at up to 1,500 RPM on a 350 mm (13.8 in) table with a BT40 spindle, while the CUBLEX-63 turns at up to 800 RPM but takes parts of nearly twice the diameter. Matsuura's MX-850 has more X travel, 900 mm (35.4 in), but less Y at 780 mm (30.7 in) and less Z at 650 mm (25.6 in). The MX-850 lists 22 / 30 kW (30 / 40 hp) of spindle power, a figure the CUBLEX-63 table does not give.
