Finger bender technology on our X2000NC This is new and revolutionary! Do you know our X2000NC? Then you know the advantages of our variable, modular machine concept. In this new model, we have consistently transferred the finger bending technology of the SPEEDMAX to the X2000NC. This model now combines all the advantages of two bending worlds. By integrating the NC bending technology in combination with our rotary positioning pliers and the servo transfer, the X2000NC is now pushing material speeds to a whole new level. E.g.: Up to 40 parts per minute, each one with up to 6 bendings and 1 press operation is possible

Different tungsten carbide qualities with a hardness above those of the standard and PM special qualities. Through clean grinding materials, we achieve a long working life through high resistance to wear.

Only the best for our forests Nowadays, forestry bears responsibility for numerous important tasks and is increasing not only in its commercial, but also in its environmental and social significance. In addition to continuous production of renewable raw materials (mainly wood) it is assuming the task of forest conservation, not least as a protected and recreational space for mankind and the animal kingdom. The predominantly municipal forestry operations are directed for the performance of these tasks at mobile woodcutters and robust wood chipping machines. We have supported the forestry industry for many years with our longlasting choppers and counterknives, as well as with shredder knives.

Rotary shear knives made from tool and PM steels in the highest OEM quality with a hardness of up to 60 HRc. CNCcontrolled machines guarantee you tight and consistent form and position tolerance for the knives. Inquire now.

State of the art machines, tightest tolerances Machine knives for use in steel production are challenging from a production engineering point of view and place enormous demands on quality. A knife change always entails a long and thus costly system shutdown; consequently, long knives and circular knives from our company are characterised not only by very high accuracy, but also by their extreme resistance to wear. In the past, we have made serious investments in our machine fleet, in order also to produce to the most complicated geometries and tightest tolerances. In addition to standard qualities, we also deliver special qualities for particular stress at high temperatures.

So that it continues The less than ideal condition of the roads in Europe, as well as the need to catch up in road construction in the Asian world has led to high investments in the construction industry. We have already specialised for many years in the manufacture of compacting bars and pressing bars for road builders. Whether casehardened or inductively hardened bars From us, you will always find a product matched ideally to your requirements.

This how each cut is made Sheet metal is available in a very wide range of materials and alloys. The criterion for machining is a given toughness and strength to make the metal sheets deformable. A part of sheet metal machining is separation by shearing, in which the sheets are divided by two shearing knives. For over 40 years, we have supplied shearing knives in lengths up to 4,190 mm in qualities and hardnesses specially matched to the purpose for the corresponding machines. By using peripheral grinding machines, we can comply with the tightest form and position tolerances, which is why so many machine manufacturers rely on the quality of our shearing knives.

Robust and durable As a naturally renewable raw material, wood is not only one of our favourite building materials, it can also be disposed of and recycled with comparative ease. For old wood recycling, tables, kitchens, damaged railway sleepers or chipboard are recycled using singleshaft shredders. In these machines, our cutting crowns and knife holders in a very wide variety of sizes and versions have been used for many years and have proven themselves in practice day after day.

Costconscious use of resources Every year in Germany, several million refrigeratorsare disposed of . With this enormous volume, refrigerators are certainly counted among the most important recycling products. After removing the chlorofluorocarbons, in a second step the housings are broken down into their individual components – iron, aluminium, copper and plastics. These are then made available again to industry as secondary raw materials. We equip our clients with extremely tough and hardwearing shredder disks and thus contribute to costconscious handling of resources.

Recycling made easy Our machine knives, of uncompromising quality, have been used for decades in recycling for tyre crushing. Even when separating rubber and spring steel, they have been proven in practice day by day. Whether shredder knives, spacers, scrapers or sealing gaskets, shredder teeth for multipleshaft shredders, rotary and stator knives for granulators or machine knives for guillotines Our complete range of products also covers the most demanding challenges in recycling.

Optimum crushing instead of cable salad The very best method for crushing of cables or electrical scrap has brought many a tool to its limits and yet this is a frequently underestimated source of money. In addition to expensive copper, the recycling process also recovers aluminium and noble metals. In order to reach these valuable raw materials, robust preliminary crushing units are used, followed by a second crushing cycle. The demands on the crushing knives cannot be ignored and they must therefore be very tough. We are at the side of our partners to give advice on the selection of ideal materials and the best heat treatment.

Clothing instead of landfill PET must beone of the most interesting recycling materials of recent years as, during this time, not only new bottles, but also clothing and much more have been produced from recycled bottles. In Germany alone, each year the volume of PET bottles discarded when empty has exceeded 400,000 [tonnes], 96% of which is taken to professional recycling. An additional 60,000 tonnes arises annually as packaging material. However, PET is an extremely abrasive material, which exacts enormous demands on the tools used in recycling. Our knives have been proven by their high resistance to wear, and we also supply, in addition to our proven quality standards, extremely hardwearing special qualities.

Less wear, longer working lives In the automobile industry, environmental protection is also playing an ever greater role. With its dimensions, bodies form by far the largest part of recyclates in automobile recycling. One of the major challenges in crushing vehicle bodies is in the vulnerability to wear of many hammer axes. We have optimised our solutions over a number of years and supply hammer axes for large shredders in various diameters, which are characterised by extreme toughness and dimensional stability. This is how our clients profit from optimum working lives for their recycling machines.

Trimmed for peak performance The construction industry is booming – and this has been the case for decades and all across the world. The need for new buildings, bridges and general infrastructure is constantly increasing. In terms of modern urban development, the demolition of buildings that are no longer up to date is part of everyday life. The stress on the tools used for this is easy to imagine. Demolition shears are used, for example, to cut angle iron or wire mesh, or to cut concrete ribs and steel rods. Our shearing knives or shear blades for mobile demolition shears are designed exactly for these massive stresses and have been used for many years on construction sites all over the world.

The O-forming press applies a press force of 4,000 metric tons per meter of pipe. This is necessary to form today’s material grades above X100 to the desired round shape at the optimum level of reduction. The control concept with (patented) multi-cylinder parallelism control ensures that the moving beam maintains a position parallel to the press table with a tolerance of +/-1 mm/m over the entire length. Combined with our tools, this results in a precise pipe gap which leads to signicant time and material savings for the subsequent welding process. The intelligent sensor and control concept of all main cylinders ensures that dierent sheet lengths (e.g., residual lengths) can be processed. The press is powered by either conventional drive concepts or via frequencycontrolled drive concepts. Our ECO Drive uses the high moving load of the moving beam to generate energy during the controlled quick lowering of the beam. This energy is fed back to the power network.
