Grinding Machine for Roll Grinding

-- Steady & Reliable Manufacturer --

Intro

This roll grinding machine is built for metal rolls — cold-mill work rolls, backup rolls, calender and chilled-iron rolls — where the drawing calls for a crown, camber or taper profile and a surface finish that transfers to the product being rolled.

Core Capability

The CNC wheelhead follows a programmed crown or camber curve along the roll body, and a heavy-duty headstock with hydrostatic steady rests carries the roll's weight. The goal is a profile and finish that stay consistent from roll to roll, with chatter marks controlled by wheel balancing and low-vibration drives.

Premium Materials and Components

Materials and components are the most critical elements to affect the performance of the equipment.

We use high-quality raw materials and branded components to ensure that our high-performance machines have a long service life and short downtime.

  • External grinding wheel chuck
  • Flat grinding wheel chuck
  • Φ 400 or Φ 600 balance frame
  • M7130-5006 front bearing
  • Rapid advance and retreat cylinder
  • Pressure valve plate assembly
  • Feed box assembly
  • Overflow valve
  • Table control box
  • Grinding head box
  • Control panel assembly
Design for High Performance

The performance of a machine is the result of the combined effect of all its components.

Our technical team consists of experienced engineers and technicians who are not only proficient in the operation and maintenance of grinders, but also have a deep understanding of material properties and processing technology. This enables us to provide customers with customized solutions to meet their specific processing needs.

By deeply studying the design and manufacturing process of precision grinding machines and paying great attention to configuration and construction from the beginning, our R&D team is able to provide high-performance equipment.

The standard version covers most cold-mill, calender and mid-size work rolls; our heavy-duty cylindrical grinding machine page covers the largest rolls. Send roll dimensions, weight and profile requirements to confirm which fits.

Roll Types Covered

Work rolls and backup rolls for cold and hot rolling, chilled-iron calender rolls and similar metal rolls, with necks ground in the same setup. Rubber and paper-machine rolls are covered by different grinding equipment and are not served by this machine.

Profile and Finish

Crown, camber and taper profiles are programmed as curves, with finish set by wheel grit and dressing. Fine cold-mill finishes need finer wheels and a slow final pass; roll shops commonly follow grinding with eddy-current inspection, and a probe interface can be supplied.

Core Functions

  • CNC crown, camber and taper grinding from programmed profile curves
  • Hydrostatic steady rests (lunettes) carrying the roll weight at the necks
  • Wheel balancing system to reduce chatter marks on the roll surface
  • In-process gauge or contact probe for diameter and profile verification
  • Roll neck grinding in the same setup as the body
  • Optional interface for eddy-current inspection probe after grinding

Quality Control

  • Bed alignment and guideway geometry checked with laser measurement
  • Profile accuracy verified on a test roll or equivalent sample where size allows
  • Wheel balancing function tested at working speed
  • Load run-in of headstock and steady rests before dismantling for shipment
  • ISO9001-certified manufacturing with documented warranty terms

FAQ

  • Q: How is crown or camber ground into the roll?
  • A: The CNC program moves the wheelhead along a stored curve as it traverses the roll body, so the profile comes from the program rather than from manual adjustment.
  • Q: What causes chatter marks on ground rolls and how are they controlled?
  • A: Wheel imbalance, drive vibration and poor steady rest support are the usual causes; an automatic wheel balancer, low-vibration drive and hydrostatic steady rests address them directly.
  • Q: Can you grind rubber or paper-machine rolls?
  • A: No, this machine is for metal rolls; rubber and paper rolls use different grinding methods and equipment.
  • Q: How does this differ from your heavy-duty cylindrical grinding machine?
  • A: This model is configured specifically for roll profiling and finish, while the heavy-duty cylindrical machine covers very large shafts and the largest rolls; we will recommend one after seeing your roll sizes.
  • Q: What is the typical lead time?
  • A: Standard capacity versions usually ship in 150–200 days; heavy versions take longer, and on-site installation is arranged separately.

Equipment Configuration

  • Heavy cast bed with wide guideways and hydrostatic or box ways
  • Heavy-duty headstock and tailstock rated for the roll weight
  • Hydrostatic steady rests with oil-film support at the roll necks
  • Automatic wheel balancer and low-vibration main drive
  • Fine filtration coolant system for finishing passes

Where It Is Used

  • Steel mills and cold-rolling mill roll shops
  • Aluminum and copper strip rolling mills
  • Calender and chilled-iron roll manufacturers
  • Independent roll regrinding and reconditioning service companies

Automation Options

  • Custom swing, length and weight capacity for your roll range
  • Profile library for your standard crown and camber curves
  • Eddy-current probe interface for post-grinding inspection
