Overview

The Okuma MILLAC 853PF 5X is a large-format 5-axis machining centre built around a long, narrow table: 3,200 × 850 mm (125.99 × 33.47 in), with linear travels of 3,050 mm on X, 850 mm on Y and 700 mm on Z (120.08 / 33.46 / 27.56 in). That proportion — over three metres in one direction and under a metre in the other two — is the whole point of the machine. It is built for long parts: structural rails and spars, extrusions, long weldments, machine beds and frames, or rows of smaller parts fixtured end to end along the table.

The X travel almost matches the table length, so nearly the entire working surface is reachable rather than losing a wide margin at each end to overtravel limits. Y travel matches the table width exactly, which means the spindle covers the full width of the table at any point along its length — useful when parts are laid out in a row and each one has features on both sides.

The spindle runs from 60 to 12,000 min⁻¹ with a 45/55 kW (60/75 hp) motor. Twelve thousand min⁻¹ with power in that range spans a wide set of work: aluminium at high speed and steel at moderate speed both fall inside it, which matters on a machine that may see aerospace structure one week and fabricated steel the next. The 60 min⁻¹ floor leaves room for large face mills and boring heads where spindle speed has to stay low.

Rapid traverse is 30 m/min (1,181 ipm) on X and Y and 24 m/min (945 ipm) on Z. On a three-metre X axis the rapid rate has a real effect on cycle time, since repositioning between features at opposite ends of the table is a genuine distance rather than an incidental move.

Tool capacity is 30. On a machine this size that figure deserves checking against the intended job: a long part with many different features will exhaust thirty pockets, and reloading the magazine part-way through undermines the long unattended runs a table this size is otherwise well suited to. It fits aerospace, rail, energy and heavy fabrication shops with parts too long for a conventional 5-axis machining centre.

Strengths & Limitations

Strengths

3,050 mm (120.08 in) of X travel over a 3,200 x 850 mm (125.99 x 33.47 in) table takes long parts that will not fit a conventional 5-axis machining centre
X travel almost matches the table length, so nearly the entire working surface is reachable rather than losing a wide margin at each end to overtravel limits
Y travel of 850 mm matches the table width exactly, so the spindle covers the full width at any point along the length - useful when parts are laid out in a row with features on both sides
A spindle spanning 60 to 12,000 min⁻¹ with a 45/55 kW (60/75 hp) motor covers aluminium at high speed and steel at moderate speed on the same machine

Limitations

Z travel is 700 mm (27.56 in) against 3,050 mm on X - this is a machine for long, comparatively shallow parts rather than deep work
Tool capacity is 30, which a long part with many different features will exhaust; reloading the magazine part-way through undermines the long unattended runs a table this size otherwise suits
Z rapid is 24 m/min (945 ipm) against 30 m/min (1,181 ipm) on X and Y, and on a three-metre axis repositioning between features at opposite ends of the table is a real share of cycle time

Best For

Long parts: structural rails and spars, extrusions, long weldments, machine beds and frames Rows of smaller parts fixtured end to end along a 3,200 mm table Aerospace, rail, energy and heavy fabrication shops whose parts are too long for a conventional 5-axis machining centre Work mixing aluminium and steel, where a 60 to 12,000 min⁻¹ spindle range covers both

Frequently Asked Questions

01 How long a part will the MILLAC 853PF 5X take?

The table is 3,200 x 850 mm (125.99 x 33.47 in) and X travel is 3,050 mm (120.08 in). Because the travel almost matches the table length, nearly the whole working surface is usable rather than losing a wide margin at each end to overtravel limits.

02 What are the Y and Z limits?

Y travel is 850 mm (33.46 in) and Z is 700 mm (27.56 in). Y matches the table width exactly, so the spindle covers the full width at any point along the length. Z of 700 mm against 3,050 mm on X describes the intended work precisely: long, comparatively shallow parts rather than deep cavities.

03 What materials does the spindle suit?

It runs from 60 to 12,000 min⁻¹ with a 45/55 kW (60/75 hp) motor. That range spans aluminium at high speed and steel at moderate speed, which matters on a machine that may see aerospace structure one week and fabricated steel the next. The 60 min⁻¹ floor leaves room for large face mills and boring heads where spindle speed has to stay low.

04 Is a 30-tool capacity enough?

It is the specification most worth checking against the intended job. A long part with many different features will exhaust thirty pockets, and reloading the magazine part-way through undermines the long unattended runs a table this size is otherwise well suited to. Map a representative program against 30 tools before committing.

05 How much does rapid traverse matter on a machine this long?

More than on a compact machine. Rapids are 30 m/min (1,181 ipm) on X and Y and 24 m/min (945 ipm) on Z. Across a 3,050 mm X axis, repositioning between features at opposite ends of the table is a genuine distance rather than an incidental move, so the rapid rate shows up directly in cycle time.
