CNC Controlled 4-Roller Precision Rolling Machine

CDOCAST 4-Roller Precision Rolling Machine is suitable for rolling various gold, silver, copper, and aluminium bar plates. The mill adopts an advanced four-roll structure, comprising five core systems:
1. High-Strength Frame
2. Precision Roll System:
3. High-Efficiency Drive
4. Smart Hydraulic System
5. CNC System

The 15HP ultra-precision CNC four-roll rolling mill features advanced four-roll technology, utilising a dual-roll system comprising Cr12MoV backup rolls and DC53 work rolls. It can precisely roll a 60mm-wide, 0.5mm-thick copper strip down to an ultra-thin 0.006mm, with thickness tolerance within ±0.002mm. Equipped with an automatic coiling/uncoiling system, it enables continuous rolling production without downtime due to material changes. The rolled metal strips exhibit smooth surfaces and burr-free edges, perfectly meeting the production requirements of high-precision electronic components and precision instruments.

This machine is particularly suitable for ultra-thin rolling of precious metals, copper alloys, aluminium alloys, and other materials. Its CNC system allows precise adjustment of rolling parameters to ensure uniform thickness. With a high-rigidity frame and optimized roll system design, it not only improves rolling accuracy but also significantly extends roll service life, making it an ideal choice for efficient precision production in industries such as new energy and electronic components.
