Knurled Micro Shaft
Precision micro shaft with a knurled section for press-fit grip.
Manufacturing Scope
Knurled Micro Shaft is a Micro & Watch Parts family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀1.5–6 mm, lengths 18–54 mm, standard material Brass (also steel, stainless, brass or aluminium). Every variant's part code, dimension and tolerance is listed below; request an instant quote with the code you need.
The family is machined from ⌀6 mm bar stock; its longest variant is MIKA-KNS-60 at 54 mm. Besides turning, the family requires knurling. All of it is completed in a single setup, without the part leaving the machine.
The most slender variant is MIKA-KNS-15: 18 mm long at ⌀1.5 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 h9 tolerance; the smallest is MIKA-KNS-15 (⌀1.5 mm) and the largest MIKA-KNS-60 (⌀6 mm). The family includes knurled, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
