Seminars for slitter operator about cutting optimization

seminar

If you want KnifeSol can support you and your workers to optimizing your slitting line. To do this we can come on site and do a cutting optimization seminar. You cannot imagine how many things hinder the optimal cutting and blade life. We can solve your problems in just four hours of seminar.

Slitter steel spacers

KnifeSol steel spacers are in 9CrSi material and have the same tolerance’s (flatness and parallelism) like circular knives. We belive that the spacer should have the same hardness at core as the circular knives. This especially, to maintain the same feature on the shaft. More and more the tools (Knives, spacers, rubber bonded steel spacers) are mounted and fixed on the shaft with a very high load. Our spacers must therefore resist these loads. But the most obvious reason is that the spacers have to resist for long time, so we also consider the possibility of an incorrect handling due by the workers that could easily damage the spacer, if they were not hardened at core.

Rubber bonded steel spacers

KnifeSol rubber bonded steel spacers have the same tolerances (flatness and parallelism) like circular knives. We believe that the spacer should have the same hardness at core as the knives’. The steel ring is usually produced in 9CrSi material, hardened at core with same hardness of circular knives’, especially, to maintain the same feature on the shaft. More and more the tools (Knives, spacers, rubber bonded steel spacers) are mounted and fixed on the shaft with a very high tightening load. The spacers must therefore resist these loads. But the most obvious reason is that the spacers have to resist for long time, so we also consider the possibility of an incorrect handling due by the workers that could easily damage the spacer, if they were not hardened at core.

KnifeSol use two type of rubber, BunaN/Perbunan and Polyurethane. The choice of rubber type depends only to your processed material. We will suggest you the right rubber for your process rules.

Scrap shear blades

KnifeSol scrap shear blades are custom made.

KnifeSol scrap shear blades are made from special ESR pre-materials using special tool steels.

All forging and heat treatment operations are performed in the same factory that produces knives. This specific choice is required to obtain the best structure and mechanical features for knives in order to improve their quality and to extend their life.

We are able to meet all types of plant processing characteristics and customer needs.

Circular slitter knives

KnifeSol’s special feature that sets us apart from our competitors is that all our circular knives are made from the finest quality alloy steel, starting with ESR pre-materials.
The ESR re-melting process improves the features of materials. The material’s structure is free of segregation and the inclusions content is significantly reduced. The ESR re-melted material also displays a more uniform distribution of carbides in the matrix; therefore mechanical properties are superior, allowing an improved durability of the knives.
The ESR re-melted pre-material, combined with a special homogenization annealing treatment and forging operation with excellent deformation, elevates the characteristics and quality of the knives, ensuring an extended service life.

KnifeSol’s
selected basic standard technology is the best basic choice for knives’ life and differs from the competitors products’ quality, since they mostly use only conventional melted materials with a view to increase profit. For your information: the material obtained from conventional melting process contains higher grade of segregations and higher grade of non-metallic inclusions, easily dectectable on micrographs. These imperfections are located on the knives’ perimeter, right where the material structure must be perfect in order to avoid fractures due to imperfections of the material. We distinguish ourselves from others since we offer a better basic quality. Finally, all forging and heat treatment operations are performed in the same factory that produces knives. We are able to meet all types of plant processing characteristics and customer needs.

KnifeSol circular knives are made only from round bars, to ensure the proper and best natural structure for the circular knives.

KnifeSol slitter knives are custom made. One of our strengths is the production of circular knives with a maximum outer diameter of 1400 mm.
