Tsumura Chainsaw Bar Technology
Laser Cutting
Laser cutting is a process that uses a focused laser beam to cut through the material, creating precise and intricate shapes with a high level of accuracy. The process is fast and flexible, allowing for the production of any bar shape, and is ideal for creating prototypes according to specific requests. Laser cutting is a great tool for making complex shapes, and it’s relatively cost-effective compared to other cutting methods like CNC machining.
Salt Bath Treatment
Suehiro Seiko has developed a salt bath heat treatment process to achieve the perfect balance between toughness and hardness in guide bars. This process involves slowly heating the steel to over 800℃, which allows the steel to develop a hardened and stable structure with minimal distortion. This slow heating process is the best way to achieve ideal steel with both toughness and hardness, and it ensures that the guide bars produced are of the highest quality. Suehiro Seiko’s salt bath heat treatment process is the perfect way to ensure that guide bars have the desired characteristics for maximum performance.
Straightening Process
Having a straight rail on a guide bar is critical for the proper operation of a saw chain, as it rotates at high speeds on the chain groove. If the rail is not straight, it can cause the guide bar to become biased and wear unevenly, as well as make it difficult to cut straight. To ensure maximum performance and accuracy, Tsumura bars have a three-step straightening process that is done after the press, heat treatment, and finishing processes. This step is done by highly skilled professionals, ensuring that the guide bars are straight and perform to the highest standards.
Epoxy Treatment in Lightweight Bars
Tsumura’s chainsaw guide bars are designed with a unique dove-tailed notching system that significantly reduces their weight. By cutting notches into the bar surface and packing them with hard resin, the guide bar weight is reduced by around 20%. This weight reduction improves cutting efficiency and stability, and it also helps reduce user fatigue. This unique design is at the forefront of technology and Tsumura bars are the lightest available on the market today.
Different Types of Tsumura Chainsaw Bars
The Tsumura Chainsaw Bar is an innovative cutting tool that offers a variety of different types and styles. Some of the most popular types include solid bars, laminate bars, solid-nose bars, and sprocket-nose bars. These bars are designed to provide users with a wide range of cutting options, from heavy-duty cutting to precision-level cutting. Additionally, the bars feature a low-vibration design, which minimizes fatigue and increases accuracy when cutting.
Solid Guide Bars
Solid guide bars are a type of bar made from one plate of super hard alloyed steel. Solid guide bars are tougher than laminated guide bars, which are made from multiple plates. There are two types of solid guide bars: the replaceable sprocket nose type and the hard nose type, in which steel tips are welded on.
The replaceable sprocket nose type has a replaceable nose part, which can be changed to extend the guide bar’s life. The hard nose type is welded on and not replaceable. Both types of solid guide bars have the advantage of being tougher than laminated guide bars, making them ideal for more demanding applications.
Laminant Guide Bars
A laminated guide bar is a type of guide bar constructed from three steel plates welded together. The guide bars produced by Tsumura have built-in sprockets on the tips. These sprockets rotate at a high speed and must be supplied with chain oil to ensure proper operation. Tsumura offers guide bars in three varieties: single rivet, four rivet and five rivet laminated types. Laminated guide bars offer an economical alternative to solid guide bars and are popular among many users.
Solid-Nose Bars
The Solid-Nose bar is designed for heavy-duty cutting and is a great choice for those who need to cut through thick materials. This bar features a solid nose that is designed to provide added strength and stability when cutting. Additionally, the solid-nose bar is designed with a low-vibration design, which helps to minimize fatigue and increase accuracy when cutting. This is the best bar choice for those who need a reliable, heavy-duty cutting tool.
Sprocket-Nose Bars
The Sprocket-Nose Bar is a revolutionary chainsaw bar design that has been developed to provide a wide variety of benefits. The sprocket at the end of the bar reduces the friction at the tip. Combine that with the high-grade steel alloy, you now have a bar that is wear-resistant and provides long-lasting and reliable performance. Additionally, the bar features a low-vibration design that reduces user fatigue and increases user safety. Sprocket nose bars are designed to be compatible with a variety of chainsaw models, making it a great choice for any chainsaw user.
How to take care of your Tsumura Chainsaw Bar
Taking care of your Tsumura Chainsaw Bar is important to ensure its longevity and proper performance. To start, make sure to always inspect the bar before and after use, to check for any damage, wear, or tear. Clean the bar regularly to remove any dirt or debris that may have built up, and use the proper lubricants and oils to keep the bar lubricated and running smoothly. Lastly, store the bar in a dry and secure place, away from any moisture, heat, or cold, to prevent any damage or rust. Following these simple steps will help you keep your Tsumura Chainsaw Bar running smoothly and efficiently.
Oiling the sprocket is an important part of regular maintenance that should be done every so often. To start, remove the bar from the chainsaw and locate the sprocket. Clean off any debris or buildup on the sprocket and surrounding area. Next, inject oil into the sprocket oil hole with the recommended bar oil type and use a small brush to apply a thin layer of oil to the outside of the sprocket. Finally, reinstall the bar on the chainsaw and run the chainsaw for a few minutes to ensure the oil has been fully distributed.
