Fixtureworks offers Imao O.D. holding clamps as part of its workholding and fixturing technologies. The O.D. clamps, available in up to 90-mm diameters in both round and square styles, allow for holding on irregular shapes and those workpieces with a circumference. The four-part aluminum jaws can also be machined to custom fit the part, while the body is made of SAE-1045 alloy steel to provide for a strong and solid base. The clamps allow for part repeatability of ± 0.03 mm and jaw locating repeatability of ± 0.02 mm, while the clamping stroke of each jaw is 0.15 mm, ideal for clamping die cast parts, extruded, solid-drawn and prefinished parts to name a few. The clamps come with a diamond pin for body locating.
The shaft and locking screw are made from alloy steel, hardened with black oxide finish. When the locking screw is tightened, the central bottom part of the jaw is pulled down. At the same time, the four jaw sections, applying equal pressure, tilt toward the center to clamp the circumference of the part. The jaws, also available separately, can be machined to hold almost any shape, and many different materials can be clamped. An adapter is also available so that the clamps can be used on a lathe.blog comments powered by Disqus
