Micro5 5-axis machining center

The compact Micro5 machining center, to be demonstrated by Chiron Group at IMTS 2022, booth 134542 in the Germany stand, is ideal for machining the smallest medical instruments and delicate parts for microprecision industry. The innovative machine is said to guarantee maximum precision for small, microtechnical workpieces such as medical, watchmaking, jewelry and small electronics.  

With a 5:1 ratio of machine to workpieces, five-times lower weight, and a much lower energy consumption than conventional systems, the 5-axis Micro5 machining center is extremely compact and quick and easy to set up almost anywhere.  

The Micro5 offers very high static stiffness, repeatability of 0.5 μm and target accuracy of 2 μm. With excellent thermal stability, very high dynamic rigidity, and acceleration of 2g, the compact machine is made for HSM. 

Many times more efficient 

The central element of the Micro5 – which is literally the size of a fridge – is a high-performance milling spindle. This reduces the machining time significantly compared to larger machines. Thanks to its particularly high rigidity, the compact, five-axis machining center also ensures high precision and optimum surface quality. At just 500 Watts, the Micro5 also consumes very little energy. It’s operated simply by an intuitive HMI panel. And with a noise level under 50 decibels, it’s quieter than a dishwasher.  

Feed5 – Greater autonomy, greater production capacity 

Early users of the Micro5 wanted the machine to allow automatic loading for higher production capacity.  For that capability, Chiron provides the Feed5, a six-axis robot for automated loading and unloading. As compact as the Micro5, the Feed5 is particularly useful for enabling increased autonomy and productivity for longer production runs. The maximum workpiece size for the Micro5 is 50 x 50 x 50 mm (L x W x H). 

"The high-precision machining center perfectly complements the Chiron product range below the 08 series vertical machining center, which handles a work cube of 450-270-360 mm.

Related Glossary Terms

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • machining center

    machining center

    CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.

  • milling


    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

  • static stiffness

    static stiffness

    Relates to the machine tool and is measured in pounds per inch. Static stiffness indicates how many pounds of force it takes to deflect the spindle a linear distance of 1" in a given direction. See dynamic stiffness; stiffness.

  • stiffness


    1. Ability of a material or part to resist elastic deflection. 2. The rate of stress with respect to strain; the greater the stress required to produce a given strain, the stiffer the material is said to be. See dynamic stiffness; static stiffness.
