Machine portfolio

Choose the right ring rolling architecture.

The catalogue samples cover conventional hydraulic systems, CNC controlled hydraulic systems, complete automatic D51K lines, D52K horizontal CNC systems and D53K radial-axial machines.

D51Y Series

Multi-Functional Ring Rolling Machine

D51Y is the catalogue's multi-functional vertical ring rolling machine for radial rolling, composite rolling and deep-groove ring forming.

  • Matched image: D51Y equipment page with ring and sleeve samples.
  • For bearing rings, flanges, support wheels and shaped ring parts.
D51YK Series

Hydraulic CNC Ring Rolling Machine

D51YK is the hydraulic CNC version, using PLC and touch-screen control to coordinate the rolling wheel, thrust wheel and signal wheel.

  • Matched image: D51YK CNC machine group with operator interface.
  • Catalogue model range includes 250E, 500E, 630E, 800E and 1000F.
D51K Series

Complete Automatic CNC Ring Rolling Machine

D51K is the catalogue's complete automatic CNC series, developed from the CNC ring rolling machine with loading and unloading manipulators.

  • Matched image: D51K complete automatic CNC workshop line.
  • Built for unattended operation with mechanical handling support.
D52K Series

Horizontal CNC Radial-Axial Ring Rolling Machine

D52K is the horizontal CNC radial-axial system shown in the catalogue's horizontal machine page, with a long-bed layout and coordinated forming units.

  • Matched image: D52K horizontal CNC layout drawing from the same page group.
  • For larger radial-axial work requiring horizontal handling and automation.
D53K Series

CNC Radial-Axial Ring Rolling Machine

D53K combines radial and axial rolling for larger rings. Operators set ring size, blank size, roller size and material grade on the CNC system.

  • Matched image: D53K large radial-axial machine photo from the D53K page group.
  • Catalogue range is shown from 400 class up to 12000 class.
SPJZ Series

Ring Sizing Machine

SPJZ is the catalogue's ring sizing machine series, used after rolling when ring diameter and roundness correction are required.

  • Matched image: SPJZ equipment photo from the SPJZ160/250/350 parameter section.
  • Supports downstream sizing and correction workflows.

Applications

Forging rings for automotive, bearing, energy and industrial users.

The catalogue shows finished parts and sample workpieces after rolling. The website groups them into practical buying categories for overseas buyers and engineering teams.

01

Bearing rings

Inner and outer rings, slewing bearing parts and large circular blanks.

02

Automotive hubs

Wheel hubs, guide wheels and vehicle mechanical ring components.

03

Flange forgings

Pipe flanges and expanded flange forgings after rolling.

04

Gear blanks

Gear blanks, ultra-wide blanks and heavy equipment ring forgings.

Why choose CNC radial-axial rolling

Built for better ring quality, faster changeover and higher automation.

The D52K horizontal CNC catalogue page compares radial-axial horizontal CNC equipment with ordinary vertical ring rolling machines. These advantages are summarized below for quick evaluation.

Stable ring quality

Flat end surface, fewer pits and burrs, stable dimensions, good roundness and reduced inner/outer diameter taper.

Wide adaptability

Works across sleeve rings, flanges and forming rings, including parts that do not require frequent die changes.

Quick product changeover

Parameters can be adjusted through the human-machine interface to shorten replacement and setup time.

Intelligent rolling curves

Numerical control completes the rolling process according to the configured rolling curve.

Remote diagnostics

Catalogue text references 4G/5G communication for remote fault diagnosis, program modification and updates.

Energy-conscious hydraulics

Variable-frequency motors and servo hydraulic design reduce power demand, oil temperature and energy consumption.

Selection snapshot

Compare product families before sending your drawing.

Final sizing should be confirmed against your drawing, material, blank dimensions and production target. Use this table as a first conversation map.

Rolling workflow

From heated blank to controlled ring geometry.

1

Prepare the blank

Cut, heat, upset and pierce the billet into a ring blank with enough material flow allowance.

2

Drive the ring

The main roller drives rotation while the mandrel and guide elements control expansion.

3

Control radial and axial geometry

CNC radial-axial systems coordinate diameter growth, wall thickness and end-face height.

4

Record mature curves

Successful production curves can be reused to shorten changeover and stabilize output.

Machine selector

Build a first recommendation before you send the drawing.

Enter a few basic requirements and the selector will suggest a product family to discuss with sales. Final configuration still depends on your ring drawing, material and production rhythm.

D51YK Series Good first fit for CNC-controlled batch production with visible operation and rolling-curve control.

Sample gallery

Catalogue sample images, organized for fast inspection.

Contact sales
