This design allows you to achieve greater precision and higher production speeds compared to traditional single-roll mills. The multi-roll setup distributes the rolling force more evenly, which reduces the risk of defects and improves the uniformity of the finished tube.

Let’s look at how multi-roll cold rolling mills differ from single-roll mills:

Component/Configuration Single-Roll Mills Multi-Roll Mills (Tandem)
Mill Stand Uses one set of rolls, flexible for smaller batches Several stands in a line for continuous production
Production Efficiency Ideal for small quantities and varied dimensions Highly efficient for high-volume manufacturing

With a multi-roll cold rolling mill, you achieve superior dimensional accuracy, excellent surface finish, and high material utilization. These features make it the preferred choice for manufacturers who demand the best in precision tubing and metal forming.


Working Principle of Cold Rolling Pipe Mill

Reciprocating Rolling Mechanism

You operate a cold rolling pipe mill using a reciprocating rolling mechanism. This process shapes metal tubes with high precision. The tube blank moves back and forth between the rolls. Each stroke reduces the diameter and wall thickness in small increments. You see the rolls form an annular gap around the tube, which creates a controlled space for deformation. The tube advances a short distance after each cycle, usually between 0.5 and 3 millimeters. You rotate the tube slightly, often by 5 to 15 degrees, before the next pass. This cycle repeats many times, sometimes up to 50 passes, until you reach the desired size.

Note: The reciprocating action allows you to achieve gradual and uniform reduction. You avoid sudden changes that could cause defects or uneven thickness.

You benefit from this mechanism because it produces tubes with consistent dimensions and excellent surface quality. The multi-roller cold rolling mill uses three to five small-diameter rolls, which distribute force evenly. This setup minimizes vibration and improves stability during rolling.


Roll and Mandrel Coordination

You rely on precise coordination between the rolls and the mandrel. The rolls create a circular or oval pass profile, while the mandrel remains fixed inside the tube. This combination forms an annular gap, which controls the tube’s outer diameter and wall thickness. You adjust the position of the rolls to change the gap size. As the rolls move along curved slides, the pass diameter decreases. You achieve incremental deformation, which is essential for producing thin-walled tubes.

The mandrel supports the tube from the inside. You prevent collapse and maintain roundness. The roll and mandrel coordination ensures that the tube receives uniform pressure from all sides. You can produce tubes with wall thicknesses as low as 0.2 millimeters. This precision is critical for applications in medical devices, aerospace, and hydraulic systems.

Tip: Advanced cold rolling machine models, such as those from Yongteli, feature servo-driven feeding systems. You control the feeding position with ±0.01mm accuracy, which enhances consistency and reduces material waste.


Pure Rolling and Speed Balance

You achieve pure rolling by balancing the speeds of the rolls and the slide mechanism. The rolls rotate without slipping against the tube surface. You use a rocker-linkage system to synchronize the movement. The slide speed (V1) and the roll center speed (V2) must match. This balance prevents surface defects and ensures uniform deformation.

You notice that pure rolling reduces friction by up to 50% compared to older two-roll mills. The tube surface remains smooth, often reaching a roughness value (Ra) of 0.8 micrometers or less. You eliminate the need for post-polishing in many cases. Speed balance also allows you to maintain tight tolerances, such as ±0.05mm for outer diameter and ±0.03mm for wall thickness.

Modern multi-roll cold rolling mills incorporate multi-line setups. You process several tubes simultaneously, increasing throughput by 30–50%. You benefit from higher efficiency and lower energy consumption. These innovations make the cold rolling pipe mill a preferred choice for high-volume, precision tube production.

Feature Benefit to You
