Material & Tolerance
The standard material is listed below; also available in steel, stainless, brass and aluminium. Dimensions in mm; tolerances machined to ISO. Deviations (mm) are given for the nominal diameter according to the ISO 286-2 tables; thread tolerances (6g/6H) are to ISO 965. For custom sizes/tolerances, contact us with the part code.
Manufacturing Scope
Micro Shaft is a Micro & Watch Parts family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀1–6 mm, lengths 12–60 mm, standard material Stainless Steel (also steel, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request a quote with the code you need.
The family is machined from ⌀6 mm bar stock; its longest variant is MIKA-MSF-60 at 60 mm. The family is produced by turning alone. All of it is completed in a single setup, without the part leaving the machine.
The most slender variant is MIKA-MSF-10: 12 mm long at ⌀1 mm, a length-to-diameter ratio of 12.0. This ratio is the very reason sliding-head lathes exist. The guide bushing supports the bar immediately beside the cutting point, so there is no deflection; the same part chatters and drifts in diameter on a conventional lathe.
Variants are machined to h5, h6 tolerance classes; the smallest is MIKA-MSF-10 (⌀1 mm) and the largest MIKA-MSF-60 (⌀6 mm). Custom sizes, tolerances or materials are produced to the part code on request.
