Manufacturing Scope
Knurled Ring is a Custom Turned Parts family precision-turned on a Goodway SW-20, covering 11 variants — diameters ⌀6–20 mm, lengths 10–26 mm, standard material Brass (also steel, stainless steel 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 ⌀20 mm bar stock; its longest variant is OZEB-KNR-15 at 26 mm. Besides turning, the family requires knurling. Bores in this family run ⌀3.2–14 mm. All of it is completed in a single setup, without the part leaving the machine.
The variant with the highest length-to-diameter ratio is OZEB-KNR-08: 24 mm long at ⌀9 mm, L/D 2.7. A short, rigid body: what governs the result here is not deflection but diameter tolerance and surface finish.
Variants are machined to h10 tolerance; the smallest is OZEB-KNR-05 (⌀6 mm) and the largest OZEB-KNR-20 (⌀20 mm). The family includes knurled, bored, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
