Estimated price range
Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Willemin-Macodel. Configuration moves it a long way.
Overview
The Willemin-Macodel 301S is listed as a 5-axis mill-turn machine for small bar work: 32 mm maximum bar diameter, a 15,000 rpm main spindle and a milling spindle that reaches 40,000 rpm. Willemin-Macodel's current pages do not show this model, and the listed figures have not been checked against the maker. Use them to judge whether a used machine is worth a closer look.
Travel is 220 mm in X, 100 mm in Y and 250 mm in Z. Y is the short axis, less than half of X, so what the milling spindle can reach across the part is bounded well before the other two axes run out. The B axis swings from -30° to +120°. That range takes the milling spindle from the end face of the bar round to its flank and beyond, so angled holes and faces can be cut in one clamping with all 5 axes moving together.
The two spindles tell you what the machine is for. A main spindle at 15,000 rpm with 9 kW keeps surface speed up when turning small diameters, and 40,000 rpm at the milling spindle suits small cutters. No power figure is listed for the milling spindle. Besides bar, the machine takes chuck work up to 80 mm. The magazine holds 38 tools, positioning accuracy is listed at 0.002 mm, the control is a Siemens 840D sl, and the footprint is about 1,400 × 1,600 mm.
For scale, the 408MT is listed with Ø36 mm bar capacity and 250 mm, 200 mm and 310 mm of travel.

Strengths & Limitations
Strengths
- Milling spindle listed at 40,000 rpm for small-diameter cutters, alongside a 15,000 rpm main spindle
- B axis range of -30° to +120° with 5 simultaneous CNC axes
- 38-tool magazine, so a family of small parts can stay set up
- Listed positioning accuracy of 0.002 mm
- Footprint of about 1,400 × 1,600 mm
Limitations
- Bar capacity ends at 32 mm and chuck capacity at 80 mm

Frequently Asked Questions
01
The listed maximum bar diameter is 32 mm, and the maximum chuck diameter is 80 mm for parts that are not made from bar. The 408MT, by comparison, is listed with a bar capacity of Ø36 mm.
02
The main spindle is listed at 15,000 rpm with 9 kW. The milling spindle is listed at 40,000 rpm, with no power figure. Those speeds point to small diameters and small tools: high rpm is what keeps cutting speed up when the part or the cutter is only a few millimetres across.
03
X, Y and Z travel are listed as 220 / 100 / 250 mm. The B axis ranges from -30° to +120°, and the machine has 5 CNC axes that move simultaneously. Y, at 100 mm, is the axis most likely to limit a part.
04
The control is listed as a Siemens 840D sl. The footprint is about 1,400 × 1,600 mm. No machine weight or power supply figure appears in the listed figures, so ask for those before planning the installation.
