Pin Manufacturing and CNC Swiss-Type Turning

146 CNC-turned pin types: DIN 7 dowel, taper, clevis and guide pins. ⌀2–20 mm, h6/H7 tolerance, steel/stainless/brass. Send your drawing for a quote.

Manufacturing Scope

Pins are precision cylindrical and tapered machine elements that align, locate, or transmit load between two parts. They are widely used in automotive, hydraulics-pneumatics, tooling, robotics, and general machinery. Our catalog spans 15 families and 146 types, including the DIN 7 dowel pin, ground precision pin, shouldered guide pin, DIN 1 taper pin, internally threaded taper pin, clevis pin, knurled press pin, hexagonal centering pin, sensor target pin, and rotary joint pin. We machine steel, stainless steel, brass, and aluminum. On locating pins we hold h6 shaft and H7 bore tolerances, reaching ±0.01 mm on critical diameters. All parts are produced on the Goodway SW-20 CNC Swiss-type lathe within a ⌀2–20 mm diameter range. Beyond the 146 cataloged types, we manufacture custom sizes to your technical drawing. The process begins when you send a drawing or sample; we then prepare a quote based on quantity and material.

Length is what varies most here: from 8 mm up to 100 mm at PIMB-TPR-20, a span of 92 mm inside one category — and all of it inside the machine's 207 mm single-setup limit. Across 146 variants the work is 42× thread turning, 22× hex flat milling, 39× axial bore, 36× taper turning, 20× knurling.

Tolerances span 9 classes (6g, g6, h10, h11, h7, h8, h9, m6, n6) and 121 variants carry a DIN or ISO reference. The highest length-to-diameter ratio in the category belongs to PIMA-TPR-06T at L/D 7.6 — slender enough to need tailstock support on a conventional lathe.

Every part is CNC-turned to your drawing — series, small batches and custom turned parts. Send your drawing (PDF/DWG/STEP) for a quote.
