How much does the OKK HM6000S cost?
Estimated price range
Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from OKK Corporation. Configuration moves it a long way.
Overview
The OKK HM6000S is a horizontal machining center with a No. 50 taper spindle running to 12000 min-1 and rapid traverse of 75 m/min in X and Z. Travels are 800 mm in X, 750 mm in Y and 880 mm in Z over a ⌀630 mm pallet, with a maximum table load of 700 kg.
The pairing of taper and speed is the defining point. A No. 50 spindle is normally chosen for large face mills and long boring tools, and 12000 min-1 on that taper means the same spindle can also run small cutters in aluminium at useful surface speeds. Rapids of 75 m/min in X and Z and 60 m/min in Y keep non-cutting time short on parts with many features spread over several faces. Z is the longest axis at 880 mm, which gives room for long tools and for reaching into deep housings.
The 700 kg table load is the limit to watch. It covers the tombstone or fixture as well as the parts, so a loaded multi-part fixture uses it up quickly. Among OKK's larger horizontals, the HM1000S carries 2500 kg on a ⌀1000 mm pallet with 1400 mm of X travel, but its rapids are 48 m/min on all three axes. OKK's table for the HM6000S lists no spindle power, torque or tool magazine size, so those need confirming before the machine is matched to a job.

Strengths & Limitations
Strengths
- No. 50 taper spindle running to 12000 min-1, so heavy tooling and high-speed small-tool work share one machine
- Rapid traverse of 75 m/min in X and Z and 60 m/min in Y
- 880 mm of Z travel, the longest axis, for long tools and deep reaches into housings
- 800 mm of X and 750 mm of Y travel over a ⌀630 mm pallet
Limitations
- Maximum table load of 700 kg, fixture included, limits heavy cast-iron and steel workpieces
- OKK's table for this model lists no spindle power or torque figure
- Tool magazine capacity and tool size limits are not in the published table

Frequently Asked Questions
01
X travel is 800 mm, Y is 750 mm and Z is 880 mm. The pallet is listed as ⌀630 mm and the maximum table load is 700 kg, which includes the fixture.
02
Rapid traverse is 75 m/min in X and Z and 60 m/min in Y. The spindle is a No. 50 taper unit with a maximum speed of 12000 min-1. OKK's table gives no spindle power or torque, so the cutting capacity behind that speed has to be confirmed separately.
03
The HM1000S is the larger machine: 1400 mm of X travel, 1100 mm of Y and 1000 mm of Z, a ⌀1000 mm pallet and a 2500 kg table load, against 800 mm, 750 mm, 880 mm, ⌀630 mm and 700 kg on the HM6000S. The HM6000S is quicker between cuts, with 75 m/min rapids in X and Z where the HM1000S lists 48 m/min on all three axes. Both use a No. 50 taper and a 12000 min-1 spindle; the HM1000S also lists an 8000 min-1 option.
