How much does the Mazak UN cost?
Estimated price range
Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Yamazaki Mazak. Configuration moves it a long way.
Overview
The Mazak UN series is two BT30 machining centers designed around machine width: the vertical UN-600/30V, which Mazak lists at 27.36 in wide, and the horizontal UN-600/30H at 38.98 in. Both have a 20,000 rpm spindle, a 20-tool magazine, 20 in (508 mm) of X travel and a 331 lb (150 kg) table load. They are production machines for small parts, meant to stand close together in a line.
The width comes from how X motion is produced. The UN-600/30V has no conventional X slide. The table's C-axis and the column's Y-axis interpolate to place the tool in X, and the Fanuc 32i CNC converts linear coordinates to polar ones by itself, so X is programmed as on a conventional vertical machining center. On the UN-600/30H the stroke is split: the column moves on a U-axis for half of the X travel and the table on the X-axis for the other half. Mazak gives that machine a combined X feedrate of 4724 IPM, made up of 2362 IPM from each of the two axes.
The spindle is built for speed, not torque. Mazak quotes 0.49 sec to accelerate from 0 to 20,000 rpm. Power is 18.5 kW (25 HP) (40% ED) and 11 kW (15 HP) continuous, delivered through a BT30 taper. That combination suits drilling, tapping and light milling with small tools in aluminium, in cycles where the spindle starts and stops every few seconds. Y and Z rapids are 2,362 ipm (60 m/min).
Between the two models, Y travel runs from 13.78 in (350 mm) to 16 in (406 mm), Z from 15 in (381 mm) to 15.75 in (400 mm), and machine weight from 9,700 lb (4,400 kg) to 13,228 lb (6,000 kg). The real choice is spindle orientation: vertical for plate-like parts loaded from above, horizontal where chips must fall clear or several faces are reached on a fixture. Mazak also notes that lubrication, air supply and other frequently serviced items sit together in an uncovered area.

Strengths & Limitations
Strengths
- Machine widths of 27.36 in for the UN-600/30V and 38.98 in for the UN-600/30H, by Mazak's figures
- 20,000 rpm BT30 spindle that Mazak says accelerates from 0 to 20,000 rpm in 0.49 sec
- 2,362 ipm (60 m/min) rapids on Y and Z, with 4,724 ipm (120 m/min) listed for X
- The UN-600/30V is programmed in ordinary linear X; the Fanuc 32i CNC makes the polar conversion
- Lubrication, air supply and other frequent-access items are grouped in one uncovered area
- Vertical and horizontal versions share the spindle, the 20-tool magazine and the 331 lb (150 kg) table load
Limitations
- Table load is 331 lb (150 kg), fixture included, which rules out heavy workholding
- The BT30 spindle is rated 11 kW (15 HP) continuous, so cutter diameter and depth of cut must stay small
- 20 tools at no more than 13 lb (6 kg) each limit the variety of operations in one cycle
- X travel is 20 in (508 mm) and Y reaches 16 in (406 mm) at most: small parts only
- X on the UN-600/30V comes from C- and Y-axis interpolation, so parts with long straight X cuts deserve a test cut

Frequently Asked Questions
01
Spindle orientation and how X is generated. Mazak lists the UN-600/30V as a vertical machining center 27.36 in wide and the UN-600/30H as a horizontal machining center 38.98 in wide. Both have the 20,000 rpm BT30 spindle, 20 tools, 20 in (508 mm) of X and a 331 lb (150 kg) table load.
02
By interpolation. Mazak explains that the machine table (C-axis) and the column (Y-axis) work together for X-axis positioning, which is what reduces the machine width. The Fanuc 32i CNC converts linear coordinates to polar coordinates automatically, so X is programmed in the same way as on a conventional vertical machining center. Mazak gives the C-axis 100 rpm.
03
The X stroke is shared. The column travels on a U-axis for half of it and the table on the X-axis for the other half. Mazak gives an X feedrate of 4724 IPM for the two together, 2362 IPM for each, with feed acceleration of 2.0 G combined and 1.0 G per axis.
04
BT30 taper and 20,000 rpm on both models. Power is 18.5 kW (25 HP) (40% ED) or 11 kW (15 HP) continuous. Mazak states an acceleration time of 0.49 sec from 0 to 20,000 rpm, which counts most in drilling and tapping cycles where the spindle starts and stops every few seconds.
05
Travel is 20 in (508 mm) in X, 13.78 in (350 mm) to 16 in (406 mm) in Y and 15 in (381 mm) to 15.75 in (400 mm) in Z, with a 331 lb (150 kg) table load. Tools may be Ø2.95 in (75 mm) to Ø3 in (76 mm), or Ø5 in (127 mm) to Ø5.12 in (130 mm) with adjacent pockets empty, up to 11.81 in (300 mm) to 12 in (305 mm) long and 13 lb (6 kg), depending on the model.
06
Mazak equips the series with the Fanuc 32i CNC. On the UN-600/30V it carries out the conversion from linear to polar coordinates for the X-axis, so the programmer does not have to. The series table also lists a C-axis range of ±360°.
