Aciera spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Aciera spindles and motor spindles — the historic Swiss builder of precision milling machines, a benchmark in watchmaking, micromechanics and gunsmithing, alongside Schaublin in the Jura Arc.
Aciera, Swiss precision milling machines for watchmaking and micromechanics
TLDR: Aciera is a historic Swiss builder of precision milling machines, widely found among professionals and technical schools of the Jura Arc (watchmaking, micromechanics, gunsmithing, model making), alongside Schaublin and Sixis, with emblematic models such as the F3 and F4.
Aciera built a solid reputation in Franche-Comté and neighbouring Switzerland as a maker of precision milling machines, widely found among professionals and in the technical schools of the region, alongside Schaublin and Sixis. The F3 and F4 models are particularly prized by gunsmithing, scale model making and watchmaking enthusiasts for their accuracy and robustness, although more compact than some German competitors such as the Deckel FP1.
A range of precision spindles in ISO 30 taper
TLDR: Aciera F series milling machines use a vertical spindle in ISO 30 taper, with no quill on certain models such as the F3 — a design difference from competing machines fitted with a sliding quill for spotting, drilling and tapping.
Aciera F series milling machines, such as the F3, use a vertical spindle in ISO 30 taper, on a head that can take additional accessories. A notable feature of certain Aciera models compared with their competitors is the absence of a quill (sliding sleeve) on the vertical head, which is needed for spotting, drilling and tapping operations — an important design difference to take into account during any intervention or accessory fitting.
