Design and production of super-large-size roll exceeding φ4,000  L: 13,000

Rolls and drums are key component parts of production facility and production lines of customers. Since the diameter of rolls is decisive to the thickness of product and length to product size, depending upon the industry and production process rolls and drums becomesφ3,000 and φ4,000 or more and their surface length becomes L: 10,000, L: 12,000 or more. Such large sized rolls and drums require huge facilities and high durability to stand for their long-time operation. At the same time, high functionality (abrasion resistance, corrosion resistance, non-pollution, excellent parting property, conductivity, sealing, mirror surface, hydrophilic, grip, appearance, lightness, toughness, low-inertia, hear resistance, lubrication, impact resistance, and high accuracy) is required for product transport and efficient shape forming.

Nomura Plating who runs “Large-size Machining + Surface Finishing.com” has brushed up its surface finishing technology long time since its foundation in the year 1916, true to its company name Plating. The Company has continued to procure and build special machining tools, testing facilities and equipment in order to add functionality to roll surface and to process large-sized machine parts. As the result of the continued effort to meet with customer requests, the Company has grown to the company who holds such superior facilities and technology to manufacture such large-sized tolls as diameter with φ4,000 and surface length with L: 13,000. Presently, market share of super-large size roll (drum) No.1 in Japan. If you wish to increase production capacity in your line and improve your product functionality, contact us freely.

Production results of super-large sized roll (drum)

< Production available size of super-large size roll (drum) >
  Diameter: ~φ4,000  Face length: ~L:13,000
As for the production of super-large sized roll (drum), the Company meets the production not only iron core but surface finishing processing of nickel plating and chrome plating of above mentioned size.

Surface finishing technology to meet with long size roll with face length L13,000

Industrial rolls are key functional component parts of the machine facility to be used carrier stage and to shape forming. Products to be carried are plenty, including iron, paper, film and functionality required to roll surface varies according to the subject products and industry. In case face length is less than L5,000 of normal tolls, there happens no problem in terms of facility of solvent tub, but in case the face length becomes L10,000 over of long size roll, it needs to have larger solvent tub to submerge. “Large-size Machining + Surface Finishing.com” can meet with maximum face length (Varies depend on the size of diameter) of L13,300 of chrome plating, L13,300 of nickel plating, L5,000 of copper plating.

The size of long sized rolls available to give surface finishing differs according to the diameter, φ, and kind of plating and surface finishing can be given to not only rolls but to plates, so kindly consult with us freely.

Single Company can meet with designing, iron core making, surface finishing of industrial rolls

Industrial rolls (drums) production flow, once consultation or order received, is shown as follows: “ Design⇒Iron core making⇒Surface finishing⇒Shipment investigation”. Above mentioned iron core making stage, large-sized special machine tools and balancing machine to measure and confirm the rotation balance in order to meet with the production of large-sized roll with φ4,000, and in the phase of surface finishing processing, similar large-sized plating solvent tub and facility to hung heavy substance. “Large-size Machining + Surface Finishing.com” holds facilities specializing to industrial rolls and can carry out above mentioned production flaw in integrated process thoroughly in house operation. Customers can consult with us from initial consultation, witness in each flaw process and confirmation of final responsibility.

Flow of iron core making of super-large sized rolls
“Iron core making” of industrial rolls (drums) starts from lathing to metal material / rolled sheet and to roll making. After assembling separately made shaft and flange into the roll (here roll becomes completed to rotate around the shaft) and its rotation balance is measured and arranged, then grinding process is given and finally completed to industrial roll. ”Large-size Machining + Surface Finishing.com” is able to manufacture various rolls, large or small.

Flow of surface finishing of super-large sized roll
After iron core making, surface finishing is given to the surface of roll in order to maintain long time the characteristics of durability and abrasion resistance under the circumstances of customer’s manufacturing field. At this surface finishing stage, large sized water tub is required to carry out plating and grinding, “Large-size Machining + surface Finishing.com” has been chosen to be entrusted because of the merit.
