The sharp choice for the sawmill industry Blades that set the standards for performance and profitability Bandsaws are the most widely used machines to cut logs because their thin kerf results in high timber yield, low amounts of sawdust, accurate cutting and good processing economy. Nevertheless, even the best bandsaws cannot compensate for poor blades. That’s why you should choose Munkfors. Our highperformance blades give the excellent and consistent sawing results you need for saving costs involved with cutting logs, bandsaw operation, manpower and timber quality. Minimum downtime Running costs are enormous for sawmills, and the powerful forces generated during high-speed sawing make the use of really sharp, resilient and wear-resistant blades crucial. Sharp blades also reduce frictional heat, which is one reason for blade failure. At Munkfors we are well aware of these factors. That’s why we produce superior blades that give sawmills minimum downtime secured by reliable equipment to avoid losing a great deal of money each minute machines lie idle. Saving costs Although a bandsaw blade, including its maintenance, accounts for just 0.6% of sawmill running costs, Munkfors products result in considerable cost-savings in three main ways: • Better utilization of raw materials in the form of higher yields and better sawing accuracy and surface finish; • Improved production efficiency through longer running times, higher feed speeds and less maintenance; • Higher operational reliability gained through higher capacity. 2 Sawmill support In addition to supplying high-performance blades to sawmills, Munkfors provides long-term support by taking full responsibility for blade lifecycles through resharpening worn blades and evaluating them to give feedback on bandsaw performance and sawing conditions. This is an important service designed to help you minimize machine downtime and maximize cost-efficiency. We can satisfy your complete service needs for the total range of tools used in your sawmill operations. Flexible and responsive Munkfors is a family-owned Swedish company that uses world-renowned high-quality materials and manufacturing techniques. We have a very modern machine park, including our own production equipment operated by highly skilled personnel. In our efforts to stay ahead of the field, we maintain close relationships with customers and receive constant feedback from them. This enables us to provide a flexible and responsive approach to satisfying market needs and to gain the information needed for continuous product improvement. 3 Dedicated support from blade supply to sawing evaluation The correct maintenance of bandsaw blades is essential for cost-effective sawing. After blades become dull, it’s not just a matter of resharpening and returning them. We check all properties of a blade and restore them to prime condition so that the blade performs just like a new one. In addition, we evaluate how the blade has been worn in order to suggest ways of improving bandsaw or processing performance.

Supplying new saw blades The strip steel we use for Munkfors blades is supplied to our specifications by leading companies in tooling and materials technology. The properties of each steel type must satisfy exactly the demands of the sawmill industry. Major requirements include high strength, exceptional flatness and straightness, excellent weldability, tight tolerances and steel suitable for stellite tipping. Because our profile-grinding method allows the use of harder steel than is possible with conventional manufacturing methods, we can increase blade reliability and stability. Furthermore, by making sure that resharpening is carried out in the best possible way to maintain cutting efficiency, the blade can be used very many hours after sharpening. To facilitate tracking and logging, each blade bears an individual number that cannot be erased by the sawing action. Maintaining used blades We may carry out several steps to restore used Munkfors blades to peak condition depending on the wear and tear they have been subjected to. For example, tensioning, straightening, levelling, teeth setting, sharpening and reswaging. Our grinding service for resharpening tools is among the most modern in the world to ensure that returned blades continue to help you achieve your processing objectives. Blade evaluation Inspecting a blade and evaluating the effect of sawing give important indicators of bandsaw performance and sawing conditions. For example, abnormal blade wear may result from too high feed speed, incorrect blade tension or worn bandsaw wheel bearings. Such an evaluation can be used to advise you of how to improve or rectify the bandsaw and/or processing performance. Taking good care of you Munkfors is big enough to take on a leading role in the business arena, but small enough to maintain personal relationships in striving for customer satisfaction. You get personal attention in response to product enquiries and requests for technical advice. And good logistics make certain that you can always depend on getting both products and backup within a short timeframe. 5 Unique profile-grin for better blades Munkfors has both deep and broad expertise in the design, manufacture and maintenance of wide bandsaw blades for the sawmill industry. This expertise has been built up from over half a century of close cooperation with our customers and the development of our own unique production technology. The high performance of our blades minimizes the damage that results from harsh sawing conditions, including gullet cracking and tooth breakage. We also provide a complete support programme for circular saws and other sawmill tools. Four delivery forms We supply wide bandsaw blades in four different forms: 1. As part of a complete sawmill support package covering blade supply, maintenance and performance evaluation. 2. Swaged or stellite-tipped welded blades that are ready for use. 3. Toothed, welded and straightened blades ready for grinding and swaging by the customer. The welded joints are made in electronically controlled machines. 4. Toothed bandsaw strips in coils packed in cases or on pallets. 6 nding technology Extop 2000 Our Extop 2000 grinding machine for high-performance bandsaw blades provides a number of benefits to ensure excellent production economy: • No grinding burrs and no untempered martensite: the entire bandsaw tooth is ground in a single step by a wide ceramic grinding wheel with very effective water-cooling; • Identical teeth: the grinding wheel is kept in uniform shape by a diamond dressing wheel after each tooth is ground; • Minimal risk of gullet cracks: this permits the use of high blade tension to increase blade stability; • Maintaining precision and feed speed: the feed speed can be increased while maintaining a high level of precision, or the precision can be improved while maintaining the same feed speed; • Wear-resistant teeth: prolongs teeth sharpness and maintenance intervals. Ultra-sharp teeth Profile grinding produces identical ultra-sharp teeth of uniform geometry. Munkfors was the first company to develop this technique, which was revolutionary when first introduced, and we have been refining it ever since. As we manufacture our own special profile-grinding machines – now in their third generation – none of our competitors have been able to copy our patented technology or produce its superior results. Unique profile-grinding technology To produce the teeth of our top-quality blades we use our own unique and patented profile-grinding method that gives: • Sharper blades • Cleaner cutting • Longer blade lifetime • Minimum downtime • Very little material waste 7 The edge to stay ahead www.pyamid.se MFS004, en-1, 0612 Munkfors is truly involved with cutting-edge technology. We lead the development of bandsaw blades and band knives for sawing and cutting in the food and woodworking industries to sharpen the production performance of our customers. Commitment to the latest manufacturing technology – often developed in-house – gives us the edge to stay ahead of the competition. Our unique manufacturing technology guarantees products of high quality and long life. More than 50 years of successful manufacturing of high-performance blades have laid the foundation for our extensive product range and sawmill support services, and provided the comprehensive knowhow essential to continuous innovation. Munkfors’ mission of enhancing the profitability of customers is complemented with a network of professional distributors that provides first-rate service and excellent product support.
