How much does the Okuma HB630 cost?
Estimated price range
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 HB630 is listed as a No. 50 taper horizontal machining center with a 630 x 630 mm (24.8 x 24.8 in) pallet and a cubic travel envelope of 900 x 900 x 900 mm (35.4 x 35.4 x 35.4 in). The table takes 1,500 kg (3,307 lb) and workpieces up to ø1,000 x 1,100 mm (ø39.4 x 43.3 in).
Everything in the listed figures points at heavy parts and heavy cuts. The spindle is No. 50 (BT50 / CAT50) at 37/26 kW (50/35 hp) peak/continuous, with 6,000 RPM as standard and 10,000 RPM as an option. Rapids are 40 m/min on X, Y and Z, a moderate rate that goes with moving a loaded 1,500 kg table. The guideway row reads linear guides on X and Y, with box ways on Z as an option, which is the choice to weigh if the work is mostly deep boring and hard roughing along the spindle axis.
A dual pallet changer is standard, and the magazine holds 60 tools with larger magazines of 120 or more as options. The control is the Okuma OSP-P500M, with the Thermo-Friendly Concept and an anti-crash system listed as standard.
Two things to settle before planning jobs: the workpiece height of 1,100 mm is greater than the 900 mm Y travel, so the top of a full-height part is not reachable in one setup, and no torque figure is listed for either spindle speed. Verify the listed figures against the machine's own specification sheet.

Strengths & Limitations
Strengths
- No. 50 (BT50 / CAT50) spindle rated 37/26 kW (50/35 hp) peak/continuous
- Table load of 1,500 kg (3,307 lb) with workpieces up to ø1,000 x 1,100 mm (ø39.4 x 43.3 in)
- Equal 900 x 900 x 900 mm (35.4 x 35.4 x 35.4 in) travels on a 630 x 630 mm (24.8 x 24.8 in) pallet
- Dual pallet changer, Thermo-Friendly Concept and anti-crash system all listed as standard
Limitations
- Standard spindle speed is 6,000 RPM; 10,000 RPM is an option
- Rapids are 40 m/min on X, Y and Z, which adds non-cutting time on parts with many short moves
- Box ways on Z are listed as an option, not standard
- Workpiece height of 1,100 mm (43.3 in) exceeds the 900 mm (35.4 in) of Y travel

Frequently Asked Questions
01
The listed maximum table load is 1,500 kg (3,307 lb). That figure covers the fixture or tombstone as well as the parts. The maximum workpiece size is ø1,000 x 1,100 mm (ø39.4 x 43.3 in) on a 630 x 630 mm (24.8 x 24.8 in) pallet.
02
The spindle is a No. 50 (BT50 / CAT50) taper rated 37/26 kW (50/35 hp) peak/continuous. The standard speed is 6,000 RPM and 10,000 RPM is listed as an option. No torque figure is listed, so ask for it if the work is heavy roughing.
03
The listed travels are 900 x 900 x 900 mm (35.4 x 35.4 x 35.4 in) in X, Y and Z, with rapids of 40 m/min on all three. Linear guides are listed for X and Y, with box ways on Z as an option.
04
60 tools as standard, with magazines of 120 tools or more listed as options. A dual pallet changer is standard, so the tool count has to cover the jobs on both pallets if they run different parts.
