Blades - Import export

The high noise level at a construction site can damage the health of construction workers and others. Residents near a building site are often suffer for weeks and months due to noise emissions. Since in most cases it is not possible to protect the whole work area of the building site against noise emissions, it must be attempted to make the individual construction machines and devices less noisy. For equipping circular building site saws, AVOLA has developed a special blade-type HM/A/SG = carbide tipping/wolf tooth/silenced. This saw blade has eight serpentine laser incisions in the master blade 8 that reduce drumming of the master blade. At the same time, these laser incisions are distributed in such a way that the master blade still retains the pretension that is needed for the stability of the saw blade when idling and cutting.

AVOLA Circular saw blade HM/A/PH for cutting polystyrene and wood Special benefits of our patented development: One saw blade for two materials For polystyrene (Styrodur and styrofoam) and wood No jamming and sticking, because the newly developed openings in the master blade ensure sufficient air cooling Even without blade replacement More safety and occupational protection Faster, more effective and environmentally friendly operation

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.

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.

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.

Market leader with OEM quality In principle, metals can be melted on numerous occasions and reworked. This is, therefore, conventional recycling, , as a new product with similar properties and of identical quality comes from a starter material. In addition to hammer axes, the scrap shearing knives used in this industry are in our product range. Since the beginning of scrap recycling, our clients have relied on our highly accurate and extremely robust shearing knives and, even today, we are, with our 100 years of experience, a market leader in this sector. You find our Webshop https//shop.buchholzgruppe.eu/shop We also supply you the necessary machine parts (knife seat and knife holder) for the overhaul of your shear.

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.

With 2,5 degree cutting angle for clean, burrfree edges With adjustable blade clearance for a most precise cut at any thickness Very precise blades made of special steel High operating safety through material guide at entrance and protective cover Springactuated hold down clamp (from 250 mm stock width) Top/bottom dead center control to monitor blade position Counter control

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.

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.

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.

As a market leader for circular building site saws and with more than 80 years of experience, we know what is important. With this knowledge, we work continually to keep products up to date, thereby offering the highest-quality, most durable and safest machines.Changes in the machinery directive For improved safety, we have developed a safety hood that has proven to significantly reduce occupational accidents as part of the revision of standard EN 1870-19 prior to the amendment of the Machinery Directive 2006/42/EC. This was awarded the EURO Test Prize of the EU Builder's Trade Associations. Since the new machinery directive went into effect in 2010, all new circular building site saws have been equipped with the newly improved safety hood and other essential safety components and have been delivered exclusively in this version.

Ideal for trimming or scoring foils and skins Blade cutting is a very fast, precise and clean process. In the automotive industry, it is particularly well suited for kiss cutting, edge cutting and for cutting notches in foils and leather skins to prepare for edge folding processes. A special form of blade cutting is scoring, i.e. the intentional weakening of leather, plastic foils and form skins to create specific tear lines, such as to allow the release of airbags. Ultrasonic cutting technology allows for even more possibilities in die and kiss cutting for foamed components with appropriate material combinations. This technology allows parts to be cut dust and chip free with a very low noise level.
