Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from Okuma. Configuration moves it a long way.

Overview

The Okuma MA-400HA is listed as a CAT 40 horizontal machining center with a 400 x 400 mm (15.7 x 15.7 in) pallet, a 2-pallet APC as standard and a 60-tool magazine. The pallet carries 400 kg (882 lb), and the maximum workpiece is 630 mm (24.8 in) in diameter and 800 mm (31.5 in) high.

The listed spindle power is 26/18.5 kW (35/25 hp), given as 10 min and continuous ratings, and rapid traverse is 60 m/min on each of X, Y and Z. That combination, a 40-taper spindle of moderate power with fast axes, suits production work in aluminium and medium cuts in steel and iron, where non-cutting time is a large part of the cycle. The 400 kg limit covers the tombstone and fixtures as well as the parts.

The control is the Okuma OSP-P300MA, and the Thermo-Friendly Concept is listed as standard. Machine weight is given as approx. 16,000 kg (35,274 lb), which is the figure to use for floor loading and rigging when a machine is being moved into a shop.

The listed figures for axis travel and top spindle speed do not agree with each other. Take both from the machine's own specification sheet before quoting work on an MA-400HA, and check the spindle speed on any machine being inspected.

Strengths & Limitations

Strengths

60 m/min rapid traverse on X, Y and Z
2-pallet APC listed as standard, so one pallet is loaded while the other is cut
60-tool magazine listed as standard
Thermo-Friendly Concept listed as standard, with the Okuma OSP-P300MA control

Limitations

The 400 kg (882 lb) pallet load has to include the tombstone and every fixture on it
Spindle power of 26/18.5 kW (35/25 hp) on a CAT 40 taper limits heavy roughing
The listed axis travel and top spindle speed figures conflict, so both must be confirmed from the machine's own documentation

Best For
