Fully Automatic CNC Metal Elliptical Tube Cold Rolling Forming Machine:

The Fully Automatic CNC Metal Elliptical Tube Cold Rolling Forming Machine is designed to cold-roll and form metal tubes into elliptical shapes with high precision and continuous automated production.

Mechanical head working speed ranges from 50 to 130 times/min. The fast traverse (movement of the tube block) is 0.16 m/s. Actual throughput depends on tube size, material and forming program.

The listed billet feed options are 1.5, 2, 2.5, 3, 4 and 5 (as provided in the product parameters). Please confirm the exact units and any additional size ranges with the manufacturer before ordering.

Overall dimensions are 9000 × 1300 × 1400 mm and the total weight of the rolling mill is approximately 15 tonnes.

The machine is fully automatic with CNC control, offering continuous production, high yield and simple operation via an operator panel. Modes can be freely switched and control is designed to be accurate and easy to use.

The machine is described as high precision with stable performance and high yield. Its design minimizes material waste and production cost while enabling continuous, consistent forming. Final tolerances depend on material, tooling and process setup.

Key parameters include head travel 450 mm, distance between rolling center and swing shaft 225 mm, distance between rolling center and crank center 435 mm, rocker swing angle 60°30′, crank radius 150 mm, connecting rod length 1304.5 mm, slideway length 210 mm, and rolling center height 850 mm. Total mechanical drive speed ratio is 7.85.

The machine provides multiple adjustments: oblique block displacement ±25 mm, slide block connecting head and upper link 22 mm, upper connecting rod and rocker joint 20 mm (lower), and connecting rod on rocker 15 mm, allowing fine tuning of forming geometry.

This type of cold rolling machine is typically used for ductile metals such as carbon steel, stainless steel and some aluminum alloys. Material suitability should be confirmed with the supplier for specific alloys, wall thicknesses and required forming severity.

The provided product description does not list specific electrical power requirements. Power, motor sizes and control voltages vary by configuration; please request the electrical specification sheet from Liaocheng Huihao Metal Products Co., Ltd. or your sales contact.

The product description emphasizes simple and safe operation but does not list specific safety devices. Standard industry practice is to include protective guards, emergency stop and interlocks. Confirm the exact safety features and CE/OSHA compliance options with the manufacturer.

The machine is described as easy to operate with a user-friendly panel and freely swappable modes. Manufacturers typically offer operator and maintenance training as part of purchase or commissioning—confirm training details with the supplier.

Regular maintenance should include lubrication, inspection of forming rolls and slideways, checking fasteners and replacement of wear parts. For spare parts availability, service plans and OEM components, contact Liaocheng Huihao Metal Products Co., Ltd. for recommended schedules and parts lists.

Yes — many rolling mills can be customized (tooling, control systems, servo options, automation add-ons) to meet specific part geometries or higher production rates. Provide your part drawings, material specs and target throughput to the manufacturer to discuss customization options and lead times.
