Estimated price range
Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Stama. Configuration moves it a long way.
Overview
The Stama MC 531/Twin is listed as a twin 5-axis machining center: two units, each with 530 mm of X travel (1,060 mm combined), an A swivel of -120° / +30° and a continuous 360° C axis, so two parts are machined on five sides at once. Stama's current lineup does not include this model, and the maker has not confirmed the table. What follows are the listed figures.
Y is 430 mm (16.9 in) and Z is 380 mm (15 in). The workpiece limit of 300 x 300 x 300 mm per station is the number to design fixtures around, since the swivel has to clear the part through its whole range. The A range is asymmetric. Swinging 120° to one side takes the part past horizontal for undercuts and angled bores, while 30° to the other covers draft angles and clearance moves.
Both spindles are HSK-A50 at 18,000 RPM with 22 kW (29.5 hp) each. No torque figure is listed, so judging roughing ability in steel needs the spindle curve from the machine's documents. The speed and taper fit aluminium and small to medium cutters.
Rapids of 60 m/min (2,362 ipm) and 36 tools per unit, 72 in total, complete a machine built for volume. Twin units pay off when both stations run the same part; a single odd job uses half the machine. The MC 531/Mill-Turn is listed with the same travels plus a turning mode of up to 1,200 RPM, for parts that also need turned diameters.

Strengths & Limitations
Strengths
- Two 5-axis units working at once, each with an A swivel of -120° / +30° and a continuous 360° C axis
- 18,000 RPM HSK-A50 spindles of 22 kW (29.5 hp) each
- 530 mm of X per station with 430 mm (16.9 in) of Y and 380 mm (15 in) of Z
- Rapid traverse of 60 m/min (2,362 ipm)
- 36 tools per unit, 72 in total
Limitations
- Workpiece size is limited to 300 x 300 x 300 mm per station
- No spindle torque is listed, so heavy-cut capability cannot be judged from the table
- A swivel reaches only 30° in the positive direction
- No table load, accuracy or machine weight figure is listed

Frequently Asked Questions
01
Yes, on the listed figures. The spindle count row describes twin 5-axis units, and the table gives an A swivel of -120° / +30° and a C rotation of 360° (continuous) in addition to X, Y and Z.
02
X is 530 mm per station, 1,060 mm combined. Y is 430 mm (16.9 in) and Z is 380 mm (15 in). The maximum workpiece is listed as 300 x 300 x 300 mm per station.
03
Each spindle is listed at 18,000 RPM maximum with 22 kW (29.5 hp) on an HSK-A50 taper. The table has no torque row, so ask for the power and torque curve before planning heavy cuts.
04
Tool capacity is listed as 2 x 36, which is 72 in total. Each unit draws on its own 36 tools, so a part needing more than 36 different tools cannot be finished on one station without changing the magazine load.
