Large‑size diameter‑reducing machines offer high production efficiency, excellent surface finish, and precise dimensional accuracy. They can extend material length, reduce material waste, and lower costs. As a non‑cutting machining device, this type of reducer boasts advantages such as high productivity, ease of operation, material savings, and stable quality. It employs hydraulic technology to reduce the diameter of round bars and similar workpieces, which are then placed in specialized dies for cold‑compression forming. This process significantly increases the density of the compressed material, thereby enhancing its tensile strength while also improving its ductility and impact toughness. The diameter‑reducing machine delivers high production efficiency. It can process 3–5 pieces per minute, offering 3–5 times the efficiency of lathe-based peeling. Each shift can produce 2,000–3,000 pieces, making it ideally suited for mass production.

High-quality diameter-reducing machine : After compression, the workpiece’s diameter, roundness, and taper errors shall not exceed 0.03 mm. Surface finish can reach Grade △7 or better, resulting in steel savings. Following extrusion, the workpiece length can be extended by 10%–15%. Taking a 20-mm-diameter round bar as an example, with an annual output of 864,000 tons, this process can save 30 tons of steel. This machine is an ideal solution for manufacturing mining bolts, anchor bolts, and long‑rod screws. It can compress material into coil‑shaped stock in a single operation, increasing both density and length while enhancing the tensile strength of the bolts.

A diameter‑reducing machine is a non‑cutting machining device that offers advantages such as high production capacity, ease of operation, material savings, and stable quality. It employs hydraulic technology to insert round steel components—such as bars with reduced diameters—into specialized dies, where they undergo a single cold‑shrinking process to achieve the desired straight‑line dimensions. For certain steels, this process can significantly increase density while enhancing material strength, all without compromising impact toughness. Moreover, it delivers high production efficiency. It can compress 3–5 workpieces per minute, delivering 3–5 times the processing capacity of a lathe. Each shift can produce 2,000–3,000 parts, making it ideally suited for mass production.

High product quality : After diameter reduction, the workpiece’s diameter, roundness, and taper errors shall not exceed 0.03 mm. Surface finish can reach above 7, and steel consumption is reduced; moreover, the workpiece can be elongated by 10%–15% following cold forming. Taking a 20-mm-diameter round bar as an example, with an annual output of 864,000 tons, this process can save 30 tons of steel. Features of the new-type diameter‑reducing machine: First, it is a chip‑free machining device that offers high efficiency, ease of operation, material savings, and stable quality. By employing hydraulic technology, it presses round bars and other components into specialized dies under cold‑forming conditions, significantly increasing the reduction ratio and density, thereby enhancing the tensile strength, ductility, and impact toughness of certain steel grades.

Secondly, the diameter-reducing machine boasts high production efficiency. It can compress 3–5 pieces per minute, achieving 3–5 times the efficiency of lathe-based peeling. Each diameter‑reducing machine can operate continuously per shift, making it ideally suited for high‑volume production. Consequently, the product quality is superior: after diameter reduction, the workpieces exhibit minimal deviations in diameter, roundness, and taper, resulting in a savings of 30 tons of steel.
