Vertical CNC Ring Rolling Machine

ALEKVS CNC Vertical Ring Rolling Machine is a precision forging equipment based on numerical control technology. It is used for rolling heated ring blanks into seamless rings of different sizes and shapes. The servo motor with reducer and ball screw ensures stable feed, reduces the effect of temperature changes, and keeps machining accuracy stable.

ALEKVS CNC Vertical Ring Rolling Machine Working Principle

The essence of ring rolling is plastic deformation of heated metal:

• The heated ring blank is mounted on the mandrel (core roller).
• The driving roll rotates actively, applying circumferential friction and radial pressure.
• The mandrel feeds radially to reduce wall thickness while expanding the ring diameter.
• Guide rolls keep the ring stable, while the measuring roll detects real-time dimensions.
• The CNC system precisely controls parameters such as rolling force, feed rate, and spindle speed, ensuring the ring meets exact dimensional tolerances.

Main Components

• Main Frame– provides rigid support and houses all core parts.
• Driving Roll– actively powered, delivers torque and rolling force.
• Mandrel (Core Roll)– feeds radially to control wall thickness.
• Guide Rolls– stabilize the ring during rolling.
• Measuring Roll (Signal Roll)– monitors outer diameter and feeds back to CNC system.
• CNC Control System– integrates PLC, servo drives, and HMI for automated operation and precision monitoring.
