Matsuura MX-330

The Matsuura MX-330 is a compact simultaneous 5-axis machining center, offered as a fixed-table machine with pallet automation available as an option. Travels are 435 mm (17.13 in) in X, 465 mm (18.31 in) in Y and 560 mm (22.05 in) in Z.

The working surface is Ø250 mm (Ø9.84 in), accepting workpieces to Ø330 × H320 mm (Ø12.99 × H12.60 in), or Ø420 × H320 mm (Ø16.54 × H12.60 in) under conditions. Table load capacity is 80 kg (176.37 lb), and that figure defines the machine more clearly than any other. Eighty kilograms covers the workpiece plus everything holding it, so fixtures must be light — an aluminum tombstone or a compact vise rather than a steel plate assembly. This is a machine for small, high-value parts, not for scaled-down versions of larger work.

The spindle matches that intent: 15,000 min-1 standard on CAT #40/BT40, with 5.5/7.5 kW and 65.1 Nm at 1,100 min-1. A 15,000 PowerUp spindle and a 20,000 min-1 option are available, as is HSK-A63 tooling. These are small-tool numbers. The MX-330 is built to run modest cutters at high surface speed with light chip loads, and heavy roughing is outside its intended range regardless of material.

Rotary travel is -125° to +10° in A with a full 360° in C, rapiding at 17 and 33 min-1. The asymmetry in A is worth noting during process planning: the table tilts far in the negative direction for undercut access but only 10° positive, so part orientation on the fixture is not arbitrary and should be settled before fixtures are built.

Linear rapids are 40 m/min (1,574.80 ipm). Tool capacity is 30 as standard with 60 and 90 available — on a 5-axis machine finishing parts in one setup, the larger magazines are usually the sensible specification.

Automation is optional: a single pallet, or a 10-pallet Floor Pallet System for unattended running. Control is Matsuura's G-Tech 31i under MiOS 4. The MX-330 suits medical, dental, optical and precision instrument work where parts are small and setups dominate cost.
