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 HB400 is listed as a horizontal machining center with a 400 x 400 mm (15.7 x 15.7 in) pallet, 560 x 640 x 640 mm (22.0 x 25.2 x 25.2 in) of X, Y and Z travel and a 15,000 RPM No. 40 (BT40) spindle. The listed figures describe a small, fast horizontal: 26/18.5 kW (35/25 hp) peak/continuous, 60 m/min rapids on X, Y and Z, and linear guides on all axes.

The maximum workpiece is ø500 x 800 mm (ø19.7 x 31.5 in). That height is more than the 640 mm of Y travel, so a tall tombstone can be loaded but its top rows may sit beyond the spindle's reach. Lay fixtures out against the travel figures, not the workpiece limit. No pallet load is listed, so the weight limit needs to be confirmed as well.

A dual pallet changer is listed as standard. The magazine holds 40 tools, with an 80-tool option, and forty is not many when two pallets carry different jobs, so the larger magazine deserves a look. The control is the Okuma OSP-P500M, and the Thermo-Friendly Concept and an anti-crash system are both shown as standard.

With 18.5 kW continuous on a No. 40 taper and a 15,000 RPM top speed, the spindle suits aluminium and light-to-medium cuts in steel and iron more than heavy roughing. No torque figure is listed. Check the listed figures against the machine's own specification sheet before planning work around them.

Strengths & Limitations

Strengths

15,000 RPM No. 40 (BT40) spindle rated 26/18.5 kW (35/25 hp) peak/continuous
60 m/min rapids on X, Y and Z with linear guides on all axes
Dual pallet changer listed as standard
Thermo-Friendly Concept and anti-crash system both listed as standard, with the Okuma OSP-P500M control

Limitations

Standard magazine is 40 tools; the 80-tool magazine is an option
Workpiece height of 800 mm (31.5 in) exceeds the 640 mm (25.2 in) of Y travel, so the top of a full-height fixture may be out of reach
No. 40 taper with 18.5 kW continuous and no listed torque figure limits heavy roughing
No pallet load is listed, so the weight limit has to be confirmed

Best For

Aluminium and light steel parts on a 400 x 400 mm (15.7 x 15.7 in) pallet High-speed machining with small tools at up to 15,000 RPM Two-pallet production where one pallet is loaded while the other is cut Parts within ø500 x 800 mm (ø19.7 x 31.5 in)

Frequently Asked Questions

01 What are the travels and workpiece limits of the Okuma HB400?

The listed travels are 560 x 640 x 640 mm (22.0 x 25.2 x 25.2 in) in X, Y and Z. The pallet is 400 x 400 mm (15.7 x 15.7 in) and the maximum workpiece is ø500 x 800 mm (ø19.7 x 31.5 in). No pallet load figure is listed.

02 What spindle does the HB400 have?

The listed spindle is a No. 40 (BT40) taper running to 15,000 RPM, rated 26/18.5 kW (35/25 hp) peak/continuous. No torque figure is listed, so ask for the torque curve if the work includes heavy cuts in steel.

03 How many tools and pallets does the HB400 have?

The standard magazine is listed at 40 tools, with 80 tools as an option. A dual pallet changer is listed as standard, so one pallet can be set up while the other is being machined.

04 Which control and standard features are listed for the HB400?

The control is the Okuma OSP-P500M. The Thermo-Friendly Concept and an anti-crash system are both listed as standard, along with linear guides on all axes and 60 m/min rapids on X, Y and Z.
