Okuma MA 400 HA Horizontal machining center 
Machíning MA - 400HA
SPACE CENTER

stable machiníng accuracies and greater relíabílíty for even higher
productívíty per Okuma's
Thermo-Friendly Concept.
Achieves stable machining accuracíes that are unsurpassed as a general purpose horizontal
machining center with superb thermal deformatíon control system, based on Okuma's original
Thermo-Friendly Concept.
This high-performance machine gives improved productivity wíth a large machining area,
high-speed rapid feedrate, and reduced running costs thanks to longer spindle service life,
easier maintenance, and outstanding lubrication control.

Manageable Deformation—Accurately Controlled
Thermo-Friendly Concept
Thermo-Friendly
Concept
The "Thermo-friendly" concept enables remarkable machining accuracy through original structural design and thermal deformation control technology. If frees you from troublesome dimensional compensation and warm-up. Exhibits exce

TAS-C: Thermo Active Stabilizer—Construction [Optional]
"Proactively" keeps the machine [construction] in optimum, stable condition during shop
environment temperature change-resulting in superb (stable) machining accuracies.
TAS-S:Thermo Active Stabilizer — Spindle [Optional]
Spindle deformation will be accurately controlled even during operations with
frequent speed changes.

Hígh accuracy
Ball screw brackets on both ends have been strengthened (integrated into the
casting)
Further enhancement of accuracy by cooling the Y-axis motor bracket
(Standard) and the ball screw (Optional)

Híghly-accurate positioning with taper cone type pallet seat.
Curvic coupling 1° indexing (Standard), NC 0.001° indexing (Optional)
•lndexing time (90°/180°)
1° indexing: 1.2/1.5 sec, 0.001° indexing: 1.4/1.7 sec
(Okuma measurements based on J1S)

Highly rigíd 3-poínt supported bed
Machine installation itself is easy, and the sturdier triangular positioning of
the foundation pads also help stabilize high accuracies.

Wíth spreadsheet simplícity —tool offsets, tílt, shape,lífe, etc—all the tool data required to cut a part caп be regístered here.
Sínce the regístered tool data is also used by Okuma auto
programming (Advanced OneTouch 1GF) and a collísíon check functíon (Collísíon Avoidance System), thís screen wíll complete the entíre regísteríng process.
The touch sensor screen pops up from the tool regístration screen.
Tool compensation values are set while looking at a guídance
message.
