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
External Fixator Pin is a Medical & Dental Parts family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀6.4–19.6 mm, lengths 74–208 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 ⌀20 mm bar stock. Besides turning, the family requires thread turning (10 sizes from M2.5 to M10), hex flat milling (AF 5.5–17) and taper turning. One variant, MEDA-FXP-10, is 208 mm long and exceeds the machine's 207 mm single-setup limit; that size is produced in two setups.
The most slender variant is MEDA-FXP-50: 129 mm long at ⌀9.2 mm, a length-to-diameter ratio of 14.0. 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 6g tolerance; the smallest is MEDA-FXP-25 (⌀6.4 mm) and the largest MEDA-FXP-10 (⌀19.6 mm). The family includes threaded, hex-drive, tapered, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
