How much does the OKK HM 630 cost?
Estimated price range
Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from OKK. Configuration moves it a long way.
Overview
The OKK HM 630 is a twin-pallet horizontal machining center with 630 x 630 mm (24.8 x 24.8 in) pallets and 900 mm (35.4 in) of travel on each of X, Y and Z. OKK's current lineup does not include a model under this name, so what follows describes an older machine. Treat the listed figures as a guide and confirm them against the documents of the machine itself.
On those figures the spindle is a 50-taper unit, BT50 or CAT50, rated at 50 kW (67 hp) with a top speed of 10,000 RPM and a 12,000 RPM option. Table load is listed at 1,200 kg (2,645 lb). A cubic 900 mm envelope over a 630 mm pallet leaves generous clearance around a tombstone, and two pallets as standard mean one can be loaded while the other is in the cut.
The B axis indexes in 1° increments, with 0.001° positioning listed as an option. That distinction matters when buying second-hand: a 1° table handles face-by-face work but cannot hold odd angles or contour in rotation, so find out which table is fitted. The magazine is listed at 80 tools and rapid traverse at 60 m/min. Machine weight is given as roughly 30,000 kg (66,138 lb), which calls for a foundation and rigging check before purchase.

Strengths & Limitations
Strengths
- Listed 50 kW (67 hp) spindle on a BT50 or CAT50 taper
- Two 630 x 630 mm (24.8 x 24.8 in) pallets as standard, so one is loaded while the other is cut
- 900 mm (35.4 in) of travel on X, Y and Z, a large envelope for a 630 mm pallet
- 80-tool magazine and 60 m/min rapid traverse in the listed figures
Limitations
- Not in OKK's current lineup, so every listed figure should be confirmed on the individual machine
- B axis indexes in 1° increments as standard; 0.001° positioning is an option and may not be fitted
- 12,000 RPM is an option over the standard 10,000 RPM spindle
- At roughly 30,000 kg (66,138 lb) the machine needs foundation and rigging planning

Frequently Asked Questions
01
No. OKK's current lineup does not include a machine under this name, so it is best treated as an older model. The listed figures, 630 x 630 mm (24.8 x 24.8 in) pallets and 900 mm (35.4 in) of travel per axis among them, should be checked against the documents of the actual machine.
02
A 50-taper spindle, BT50 or CAT50, with 50 kW (67 hp). The standard top speed in the listed figures is 10,000 RPM and 12,000 RPM is an option. No torque figure is listed, so low-speed cutting capacity cannot be judged from the table.
03
Only with the option. The listed figures give 1° increments as standard and 0.001° as optional. A 1° table covers square and angled faces at whole degrees; work that needs finer angles or rotary contouring requires the 0.001° table, so check which one a given machine has.
04
Table load is listed at 1,200 kg (2,645 lb), fixture included, on a 630 x 630 mm (24.8 x 24.8 in) pallet. X, Y and Z each travel 900 mm (35.4 in). Two pallets are standard and the magazine is listed at 80 tools.
