Willemin-Macodel’s 701S three-axis micromachining center offers a compact footprint measuring 1 m2 and reduced energy consumption for toolmaking, watchmaking and micromold applications. The machine accommodates workpieces ranging to 52 mm in diameter and 32 mm long, and is said to achieve surface finishes ranging to Ra 0.25, reducing the need for polishing and the risk of degrading workpiece geometry.
According to the company, the machining center works fully by interpolation, meaning that all tool paths are recalculated constantly. The machine’s design is based on delta-type parallel kinematics with a workpiece holder basket connected to three arms, minimizing weight in motion and reducing the number of required tools. High-resolution measuring rulers of less than 10 nanometers promote precision.
The machine’s spindle ranges to 80,000 rpm and uses a shrink-fit toolholding system. The spindle and 36-position toolchanger accommodate tools measuring 6 mm H5 in diameter and ranging to 33 mm long. The 12-pallet magazine is equipped with 54 × 54-mm pallets and a 3R clamping system. A vision system aids the positioning of the tool, and a probing system helps to ensure correct workpiece positioning.
