How much does the OKK VC-X500L cost?
Price estimate
We do not have a price for the OKK VC-X500L that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The OKK VC-X500L is a 5-axis vertical machining center with a tilting A axis and a rotating C axis under a 12,000 rpm, No. 40 taper spindle. Linear travels are 700 mm (27.6 in) in X, 850 mm (33.5 in) in Y and 610 mm (24.0 in) in Z, and the work sits on a Ø500 mm (19.7 in) pallet rated for 250 kg (551 lb). What sets it apart from a milling-only 5-axis machine is the C axis: OKK lists a lathe mode in which it turns at 1,000 rpm, so round features can be turned in the same clamping as the milled ones.
The A axis swings from -120 to +30 deg and the C axis covers 360 deg. That range lets the spindle reach the five open sides of a part and work past horizontal on undercut faces, with 30 deg of tilt available in the opposite direction. In positioning moves A runs at 25 rpm and C at 100 rpm. Y travel is longer than X travel, 850 mm against 700 mm, so check the fixture layout against the real envelope instead of assuming the usual proportions of a vertical machine.
Rapids are 48 m/min (1,890 ipm) in X and Y and 32 m/min (1,260 ipm) in Z. The table load is the figure to plan around. 250 kg (551 lb) has to cover the fixture, the chuck or vise and the part, and in lathe mode that whole mass spins at up to 1,000 rpm, so balance matters as much as weight.
The magazine holds 40 tools as standard, with 60, 80 and 120 listed as options. A machine that mills and turns in one setup needs rotating cutters and turning tools side by side, so the tool count for a family of parts runs higher than on a milling-only machine, and the larger magazines are extras. OKK's table for this model gives no spindle power or torque, so cutting capacity in harder materials has to be confirmed with the builder.

Strengths & Limitations
Strengths
- C axis runs at 1,000 rpm in lathe mode, so turned diameters and faces can be cut in the same setup as 5-axis milling
- A axis range of -120 to +30 deg with 360 deg on C gives access to undercut faces as well as the five open sides
- Rapids of 48 m/min (1,890 ipm) in X and Y and 32 m/min (1,260 ipm) in Z
- 40-tool magazine as standard, with 60, 80 and 120 tools listed as options
- 850 mm (33.5 in) of Y travel and 610 mm (24.0 in) of Z over a Ø500 mm (19.7 in) pallet
Limitations
- Table load is 250 kg (551 lb) including fixture and workholding, which rules out heavy castings and large steel billets
- Magazines of 60, 80 and 120 tools are options; the standard machine carries 40
- OKK's table for this model lists no spindle power or torque, so roughing capacity cannot be judged from the published figures
- A tilts only 30 deg in the positive direction, so steep undercut access comes from the -120 deg side and the part must be rotated on C to present other faces

Frequently Asked Questions
01
Yes. OKK lists a lathe mode in which the C axis runs at 1,000 rpm, against 100 rpm when it is used as a positioning axis for milling. The milling spindle is a No. 40 taper unit running to 12,000 rpm. The table does not say how turning tools are held in the spindle, so raise that when specifying the machine.
02
X is 700 mm (27.6 in), Y is 850 mm (33.5 in) and Z is 610 mm (24.0 in). The A axis tilts from -120 to +30 deg and the C axis rotates through 360 deg. Rapid traverse is 48 m/min (1,890 ipm) in X and Y, 32 m/min (1,260 ipm) in Z, 25 rpm on A and 100 rpm on C.
03
The maximum table load is 250 kg (551 lb) on a Ø500 mm (19.7 in) pallet. That figure includes the fixture and any chuck, so the usable part weight is lower. For turning work, where the C axis runs at up to 1,000 rpm, the load also needs to be balanced about the axis of rotation.
04
The standard magazine holds 40 tools. OKK lists 60, 80 and 120 tools as options. The spindle taper is No. 40. Maximum tool diameter, length and weight are not in the table for this model, so check those limits before planning long boring bars or large face mills.
05
The VP 600 is OKK's vertical machining center with a 1300×610 mm table, 1120 mm of X travel and a 1200 kg table load. The VC-X500L gives up that table area and load for the A and C axes: its pallet is Ø500 mm (19.7 in) and its load 250 kg (551 lb), but it reaches angled faces and turns in the same setup. Both use a No. 40 taper, and the VP 600 lists 20000 and 30000 min-1 spindle options above its standard 12000 min-1.
