DanCut - Danieli Blades

Danieli aims to supply the best technical and economical solutions for customers' specific shearing applications. For this reason, it proposes different blade materials for flat and long products and consequently created a dedicated series identified by the cutting characteristics, for example different materials for hot and cold cutting applications. We can propose complete study and consulting to reach the best performances.

We propose tailor-made solutions, such as: New Materials, including alternative materials for blades in dedicated steel grades to ensure even better performances than our excellent standard materials; New Shapes, with complete evaluation of correct materials, depending on the application; New Blade Inserts, such as inserts in multiple materials assembled on a common steel body and with the same external dimensions as the single-piece model; and services, such as Blade Resharpening/Repairs.

NEW BLADE MATERIALS

We can supply alternative materials for blades in dedicated steel grades to ensure even better performances than our excellent standard materials.

For example, with Dancut850 we have developed high-performance knives for intermediate conditions in cut-to-length situations. Cut-to-length temperatures from 300°C to 700° in the normal use, reaching 850°C in some specific applications.

> The high ductility of Dancut850 makes it possible to obtain a longer tool life and more constant production thanks to reduced maintenance.

> The high hardness and strength together with excellent dimensional stability make Dancut850 an excellent substrate for surface coatings.

> Dancut850 boasts excellent hardenability and unique characteristics that make it particularly suitable for producing large molds. For this reason, Dancut850 is supplied in very large formats.

NEW BLADE TECHNOLOGIES – CLADDING AND TAILOR-MADE SOLUTIONS

We can produce special blades with cutting profiles in high-performance cladded material for extreme working conditions. On demand we can supply two different variants to DanCut710:

> Inserts in DanCut710 on a steel body, to guarantee material performances and the possibility to change the wear component only, instead of the complete blade.

> Cladding of an appropriate layer of DanCut710 on a steel body, to guarantee material performances in the cutting zone. We also offer refurbishment of the blades.

IMPROVED SHEAR BLADE DESIGN

In long-product cutting practice, such as for bars, channels, angles, beams, etc., blade design modification is very common: shear blades must be tailor-made to function for the profile that’s  being cut and the mechanics of the machine. Danieli’s activity consists of verifying the shearing technological parameters by analyzing the roll-pass design, shear kinematics and dynamics, and re-engineering the blades with the latest philosophy applied to the newest plants. The same activity may be carried out for an expanded product mix if the blade must cut new products not foreseen in the original plant design.

BLADES INSERTS

We offer our customers the possibility of making specific blades with inserts in multiple materials, assembled on a common steel body and with the same external dimensions as the single-piece model. This is mainly utilized for special uses or extreme working conditions, such as very high temperatures. Various customized studies and supplies of blades have been carried out for wirerod lines, with inserts in three different materials, to test them as a sample of what the customer procures, providing satisfying results and leading to new development of knives as a further evolution of those already supplied.

A long-standing customer has also found in us a partner to help develop some solutions never before implemented. Among these are blades with inserts used for his Flying Shear, an application generally used on knives with larger dimensions. In this case we have tried to take advantage of this request, giving the customer the opportunity to test different materials and compare those with existing ones not supplied by Danieli.

BLADE RESHARPENING/REPAIRS

This activity generally consists of performing grinding and resharpening on used blades. Thanks to Danieli Service’s knowledge and experience, we can repair any kind of blade as well as supply compensation shims. With Danieli Service grinding machines, using special grinding stones and appropriate speed parameters, we can bring used knives to a new life.

We support customers worldwide thanks to the Danieli Service network of workshops, and where this is not possible we help customers by providing procedures and advise on how to perform blade repair. We also provide this sort of service on a Long-Term Agreement basis, by which customers periodically ship a certain number of blades to Danieli Service workshops, and in a short time the repaired pieces are returned. With this approach, the customer can control and reduce the cost of knife management.

Danieli Service performs resharpening activities for long-product mills with CNC milling machines equipped with high-tech tools and capable of hardened steel milling up to 62 HRC, with outstanding surface finishing, comparable to those achieved by grinding. For longer shear blades typical of flat product rolling mills and processing lines, Danieli Service uses CNC grinding machines with specific grinding wheels for proper material removal without shear blade-surface overheating. Shear blade re-sharpening will maximize the cost-efficiency of each shear blade and reduce lead times compared to a new purchase.
