LEVELER ROLLS & BACKUPS

  • COMESA S.r.l. specializes in the manufacture of steel wear-parts in accordance with customer’s drawings and possesses the deepest knowledge of heat treatment techniques and steel processing.
  • Due to our experience accumulated over 30 years in the steel industry and for the high quality of our products, COMESA is now the O.E.M. Supplier to the largest makers and users of steel processing plants across the Italian, European, and World markets.
  • Our constant co-operation with the most important North European Steel Producers also permits us to source the supply of raw material on short deliveries and at highly competitive prices.
  • Additionally, COMESA is able to recommend and supply alternative heattreatment processing to meet special mechanical or physical requirements of our products.

COMESA

  • Comesa Hot Plate Leveller Rolls are manufactured from hot, forged grade steels to withstand high thermal shock. The Work Roll bodies are normally deep-drilled to permit internal cooling, commensurate with the actual machine design and in accordance with the customer’s requirements.
  • Comesa Cold Plate Leveller Rolls are produced from forged grade steels dependent upon the materials being processed, to withstand the high pressures and actual working conditions. Particularly high steel hardness and depth of hardening guarantee the highest wear resistance.
  • Work and Intermediate Rolls for Levellers and Tension Levellers – The Leveller is a Multi-Roll Machine that submits the material to alternate plastic deformation due to the roll diameters and geometry selected dependent upon the type and thickness of the material being processed. This is critical in obtaining a near-perfect levelling result. Comesa rolls are produced from quenched, tempered and hardened alloy steels and, where appropriate, are coated, chrome-plated or shot-blasted etc., dependent upon the final application. Comesa rolls are employed for levelling a wide range of materials, including: carbon steels, stainless steels, aluminum etc.
  • Rolls for Coils and Sheets Straightening – Comesa rolls are produced from quenched, tempered and hardened alloy steels and, where appropriate, are coated, chrome-plated, shot-blasted, W.C. etc., dependent upon the final application. Comesa rolls are employed for straightening sheets and coils of a wide range of materials, including: carbon steels, stainless steels, aluminum etc..
  • Comesa is also able to provide a very fast and efficient refurbishing service for all rolls.
  • Raw Material – Comesa buys the raw material (Round Bars in Ø from 10 to 1,000 mm) exclusively from certified and tested E.U. suppliers of standard steel grades. Thanks to our extensive warehouse facilities, we always carry a good stock of material (up to 250 mm in diameter).
  • Cutting – The raw material is cut in our separate saw-shop for the optimum, efficient control of the various diameters and is equipped with semi-automatic, high-speed, precision band-saws. •
  • Turning – Thanks to a constantly maintained machining inventory to meet the ever-changing production demands, Comesa’s turning facilities comprise a variety of both conventional and N.C. lathes handling up to 1,000 mm diameter x 12,000 mm length.
  • Heat Treatment – Our heat treatment is always carried out by our certified and tested partner company of 20 years cooperation. Main heat treatments are Induction Hardening, Through Hardening Case Hardening and nitriding, etc.
  • Grinding – Our grinding ability is a key strength of Comesa’s production, performed by a series of precision grinding machines working on centers and handling up to ,.000 mm diameter x 6,500 mm length within tolerances of a few microns.
  • Chromium Plating – chrome plating and finished polishing of workpieces to achieve a surface finish of Ra ≤ 0,1 µm.
  • Marking – To facilitate product tracking, we employ either a punched mark or acid etching of the Comesa logo, the year of manufacture and the manufacturing identification file number which we hold in our records for a period of 10 years.
  • Packaging – Our standard packing is in a wooden box, or, if required, special packaging with different protective finishes to safeguard components for lengthy storage and/or transit conditions.
  • Quality – Each workpiece in the manufacturing schedule carries certification of every stage of manufacture. Our inspection department can perform dimensional inspection, destructive or nondestructive testing on request.
  • After Sales Services – All Comesa products are supplied with our assurance of your receiving, both during and following use, the continued and prompt support of our Commercial and Technical teams, in guaranteeing the correct operation and solving of any eventual problem.
