How much does the Mazak VARIAXIS j cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from Yamazaki Mazak. Configuration moves it a long way.
Overview
The Mazak VARIAXIS j series has two models, the VARIAXIS j-500 and the VARIAXIS j-500/5X, and one set of figures between them. Travel is 14 in (356 mm) in X, 22 in (559 mm) in Y and 20 in (508 mm) in Z, the trunnion table carries 441 lb (200 kg), and the CAT No.40 spindle runs to 12,000 rpm with an 18-tool magazine.
What separates the two is how many axes move at once, and the control that goes with it. The j-500 offers simultaneous 4-axis control with A-axis indexing in 0.0001° increments; Mazak calls this multi-surface machining and pairs it with MAZATROL SmoothG. The j-500/5X has simultaneous 5-axis control for three-dimensional curved surfaces and runs MAZATROL SmoothAi. The decision therefore starts with the parts. Prismatic work reached from several sides is covered by the j-500. Blades, impellers and sculpted forms need the 5X.
Mechanically the series is built for rigidity at a small size. The trunnion supports the table on both sides, the tilt and rotary axes use roller gear cams that Mazak says eliminate backlash, and X, Y and Z ride on linear roller guides. The A-axis swings from -120° to +30°. Rapid traverse is 1,181 ipm (30 m/min) on all three linear axes.
The spindle is modest: 7.5 kW (10 HP) continuous and 11 kW (15 HP) (40% ED), with 35 ft-lb (47 Nm) continuous torque and 48 ft-lb (65 Nm) (40% ED). Mazak lists a high-speed spindle as an option. Tools can be Ø4 in (102 mm), or Ø5 in (127 mm) with adjacent pockets empty, 12 in (305 mm) long and 18 lb (8 kg).
A 2-pallet changer is optional, as is the RMP600 wireless touch probe used with the MAZA-CHECK calibration routine. The machine weighs 15,432 lb (7,000 kg) and is 112 in (2,845 mm) high.

Strengths & Limitations
Strengths
- Trunnion table supported on both sides, with roller gear cams on the tilt and rotary axes
- Choice of simultaneous 4-axis plus A-axis indexing on the j-500 or simultaneous 5-axis on the j-500/5X
- A-axis indexing increment of 0.0001° on the j-500
- Linear roller guides on the X-, Y- and Z-axis
- A 2-pallet changer is offered as an option for setting up the next part during machining
- Ai Thermal Shield suppresses changes in the cutting edge position as spindle speed and machine temperature vary
Limitations
- Table load is 441 lb (200 kg), fixture included
- 18 tools in the magazine, which is few for multi-face work on mixed parts
- 7.5 kW (10 HP) continuous and 35 ft-lb (47 Nm) continuous torque limit roughing in steel
- Rapid traverse of 1,181 ipm (30 m/min) is slow beside the 2,362 ipm (60 m/min) X and Y rapids of the VARIAXIS i-500
- The high-speed spindle, the 2-pallet changer and the RMP600 wireless touch probe are options

Frequently Asked Questions
01
Axis control and CNC. Mazak describes the j-500 as simultaneous 4-axis with A-axis indexing in 0.0001° increments, for multi-surface machining, with the MAZATROL SmoothG control. The j-500/5X is simultaneous 5-axis, for three-dimensional curved surfaces, with MAZATROL SmoothAi. The series table gives both the same travel, table load, spindle and 18 tools.
02
Travel is 14 in (356 mm) in X, 22 in (559 mm) in Y and 20 in (508 mm) in Z, and table load is 441 lb (200 kg). The VARIAXIS j-500 table is listed at Ø19.69 in (500 mm) × 15.75 in (400 mm). The A-axis tilts from -120° to +30°.
03
A CAT No.40 spindle at 12,000 rpm. It is rated 7.5 kW (10 HP) continuous and 11 kW (15 HP) (40% ED), with 35 ft-lb (47 Nm) continuous torque and 48 ft-lb (65 Nm) (40% ED). Mazak also lists a high-speed spindle as optional; its figures are not in the series table.
04
The VARIAXIS i-500 has the same 14 in (356 mm), 22 in (559 mm) and 20 in (508 mm) of travel but carries 661 lb (300 kg), holds 30 tools, is rated 15 kW (20 HP) continuous and weighs 17,637 lb (8,000 kg). The j series carries 441 lb (200 kg), holds 18 tools and is rated 7.5 kW (10 HP) continuous. It is the lighter-duty machine on the same working envelope.
05
A high-speed spindle, a 2-pallet changer and the RMP600 wireless touch probe are all described as optional. Mazak also describes MAZA-CHECK, which measures and compensates misalignment and inclination of the rotary axis, and Ai Thermal Shield, which suppresses changes in the cutting edge position from spindle speed and machine temperature.
06
Mazak describes a trunnion design that supports the table on both sides for heavy-duty machining. The tilt and rotary tables are driven through roller gear cams, which it says remove backlash, and the X-, Y- and Z-axis use linear roller guides. The load limit in the table remains 441 lb (200 kg).
