Smooth Surgical Pin
Straight-shank surgical fixation pin with double trocar-tapered tips.
Manufacturing Scope
Smooth Surgical Pin is a Medical & Dental Parts family precision-turned on a Goodway SW-20, covering 10 variants — diameters ⌀1.5–5 mm, lengths 68–162 mm, standard material Stainless Steel (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 ⌀5 mm bar stock; its longest variant is MEDA-SPN-50 at 162 mm. Besides turning, the family requires taper turning. All of it is completed in a single setup, without the part leaving the machine.
The most slender variant is MEDA-SPN-16: 73 mm long at ⌀1.6 mm, a length-to-diameter ratio of 45.6. 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 h6 tolerance; the smallest is MEDA-SPN-15 (⌀1.5 mm) and the largest MEDA-SPN-50 (⌀5 mm). The family includes tapered, multi-step variants. Custom sizes, tolerances or materials are produced to the part code on request.
