WINTERSTEIGER Sägen GmbH
Tradition and Progress
We produce band saw blades with the Banso brand name for use in joiner saws, mobile saw mills, resaw and log band saws as well as food saws for our customers in 52 countries.
In addition to the wide variety of the standard saw range we also produce stellite-tipped saw blades and band saws with hardened tooth tips or FLEX-BACK – a special hardening process for longer service life. We also offer special models at the customer’s request plus metal-cutting band saw blades and saw blades for the processing of plastics.
Thanks to state of the art production systems and an extensive, well-stocked strip steel warehouse housed in the new factory we moved into in March 2006, we can fulfil large orders and meet special requirements at short notice and with the highest quality.
As a competence centre for saws in the WINTERSTEIGER Group, we manufacture all our carbide and stellite® saw blades exclusively for the thin-cutting frame saws and the thin-cutting band saws of Division Woodtech.
The key principle of our quality policy is customer satisfaction. As a result, quality consciousness is an integral part of our corporate management strategy which stamps its mark on all areas of the company.
Banso band saw blades are specially optimised to the specific application and the material to be cut thus delivering the best results to our customers with maximum quality and cost efficiency.
From selection of the raw material to planning, execution and inspection of production to dispatch of the finished product, our highly-qualified and responsible employees take great care to ensure the best possible quality at the highest levels on an ongoing basis.
The production quality of the strip steel is crucial for the quality of the band saw blades. The material properties of quality steel strip described according to DIN standard allows too wide tolerances for our quality criteria, therefore we add additional internal quality criteria for the acceptance of the strip steel before passing our material analyses.
The straightness, flatness and surface condition of the strip steel as well as its dimensional accuracy in respect of thickness should show no substantial differences through-out entire delivery batches consisting of tons of the respective dimension. Only compliance with all of these criteria enables the production of a saw blade with constant accuracy that is maintained during tooth-cutting, sharpening and setting.
The Banso band saw blades are manufactured from German high-grade steel that offers the perfect combination of hardness, toughness and flexibility. State-of-the-art production methods in tooth-cutting, setting and sharpening ensure highest quality, perfect cutting, and long service life for this saw type.
There are two ways of cutting the teeth in strip steel to produce a band saw blade: The most common one is toothcutting by means of punching. The other alternative – and best in terms of quality – is deep grinding.
Our production facility has four machines for punching with a very high feed rate and one deep grinding machine.
The accuracy of the tooth pitch and tooth shape when punching depends largely on the precision of the forward feed and on the quality of the tooth-cutting tool when it is ground. Both factors are therefore subject to constant inspection by our qualified staff. Manufacture by means of deep grinding links tooth-cutting with precision grinding of the band saw blade. The surface quality of the ground material is free of burrs as the grinding wheel is held permanently in the same place by a diamond dresser.
Several welding machines of different dimensions are available for saw dressing. The quality characteristic common to them all is that they are equipped with temperaturecontrol devices for automatic measurement and control of the tempering temperature. This extremely efficient measure makes it possible to avoid the consequences of incorrect tempering temperatures such as cracks in the weld seam.
Upstream processes of the dressing, such as setting or grinding, are carried out by a large number of the latest, fully automatic machines.
The setting of several teeth in one work sequence not only has substantial advantages for the forward feed and thus the work output; the setting accuracy is also very beneficial in that the resilient force arising on setting a single tooth is considerably minimized.
Almost all the production – with the exception of just a few special designs – is using Borazon grinding machines. Along with automated production, this has the advantage of a tooth ground with high precision and extreme sharpness. As a result, the surface roughness of conventional sharpening processes is reduced to an absolute minimum, the Borazon grinding wheels retain their profile throughout a very long production period, and the pressurized cooling fluid prevents overheating during the grinding process.
The finished saw blades are packaged to the highest technical requirements with safety, material conservation and environmental compatibility in mind before being sent for dispatch.
