How much does the Stama MC 422/Twin cost?
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 422/Twin is listed as a compact twin vertical machining center: two independent units, each with 420 mm of X (840 mm combined), 350 mm (13.8 in) of Y and 330 mm (13 in) of Z. The table has no rotary axis rows. Stama's current lineup does not include this model and the maker has not confirmed the numbers, so they are the listed figures only.
Small parts are the whole point. Workpiece size is 250 × 250 × 250 mm per station and table load is 150 kg per station, so fixtures have to be light: the plate, the clamps and the part all count against that 150 kg.
Each spindle is HSK-A50 at 15,000 RPM with 22 kW (29.5 hp) and 95 Nm (70 ft-lb). The torque is modest and fits the drills and end mills an HSK-A50 holder normally carries, with the power available at speed. Rapids of 60 m/min (2,362 ipm) matter more here than on a large machine, because short moves between many small features make up much of the cycle.
Each unit has 32 tools, 64 in total, and positioning accuracy is listed as ±0.004 mm. The units are described as independent, which is the difference from a fixed-spacing twin-spindle such as the MC 326, listed with 300 mm between spindle centres. No machine weight or power supply figure is given.

Strengths & Limitations
Strengths
- Two independent units, each with 420 mm of X, 350 mm (13.8 in) of Y and 330 mm (13 in) of Z
- 15,000 RPM HSK-A50 spindles with 22 kW (29.5 hp) and 95 Nm (70 ft-lb) each
- Rapid traverse of 60 m/min (2,362 ipm)
- Listed positioning accuracy of ±0.004 mm
- 32 tools per unit, 64 in total
Limitations
- Table load is 150 kg per station, fixture included
- Workpieces are limited to 250 × 250 × 250 mm per station
- Spindle torque of 95 Nm (70 ft-lb) limits large-diameter cutters and heavy tapping
- No rotary axis appears in the table

Frequently Asked Questions
01
The spindle count is listed as 2, described as twin independent units. Each unit has its own 420 mm of X travel, 840 mm combined, its own 22 kW (29.5 hp) spindle and its own 32 tools, so two parts are machined at the same time.
02
Workpiece size is listed as 250 × 250 × 250 mm per station and table load as 150 kg per station. The load figure has to cover the fixture as well as the part, which keeps this machine to small components.
03
Each of the two spindles is HSK-A50 with a maximum speed of 15,000 RPM, 22 kW (29.5 hp) and 95 Nm (70 ft-lb) of torque. These are the listed figures and the maker has not confirmed them.
04
Rapid traverse is listed as 60 m/min (2,362 ipm) and positioning accuracy as ±0.004 mm. No repeatability or acceleration figure is given, so cycle-time estimates should be checked with a trial on the actual machine.
