The multi-tooth high-speed cold rolling mill is a type of precision metal processing equipment that uses

 multiple rolls or specially shaped toothed rolls, capable of high-speed continuous rolling. It's widely used

 in the cold processing of precision tubes, strip steel, and special alloy materials.

Main Features

- Multi-roll/Toothed Roll Structure: Achieves large diameter and wall thickness reductions while improving

 surface finish and dimensional accuracy through multiple rolls or toothed roll surfaces.

- High-Speed Continuous Rolling: Uses servo motor drive, closed-frame design, and dual fan-shaped block

 balancing to enable nonstop feeding, continuous rolling, and high efficiency—up to 2.5–3 times that 

of ordinary machines.

- High-Precision Control: Infinitely adjustable feeding, rotation angle adjustable from 0–90°, with finished

 tube OD/wall thickness tolerance as tight as ±0.05mm, and surface roughness Ra ≤ 0.4.

- Wide Material Compatibility: Can process carbon steel, stainless steel, alloy steel, high-temperature alloys,

 copper, aluminum, and other non-ferrous metals.

Typical Structure and Components

A multi-tooth high-speed cold rolling mill usually includes:

- Feeding Mechanism: Stacking, flipping, and chuck pushing of billets.

- Mandrel Device and Chuck: Fixing and clamping the tube billet.

- Frame and Rolls: Multi-roll or toothed roll surfaces for deformation and rolling.

- Feeding Mechanism: Servo motor-driven with high-precision feeding.

- Discharge Mechanism: Quickly pulls out finished tubes and collects them.

- Control System: Main control cabinet, touch screen, fault diagnosis, and process interlock.
