Japan's DAIA rebar cold cutting technology: complete guide, specifications and benefits for welding forgings\r\n\r\n A revolution in rebar preparation for forging welding\r\n\r\nA unique product engineered in Japan, the DAIA (DAIA) SDC Series Rebar Cold Cutting Saw defines a new standard in rebar preparation for the sensitive butt forging welding process. Using advanced cold cutting technology, this specialized device creates a completely smooth, perpendicular surface without metallurgical defects, which dramatically increases the final quality of the connection. This device is not an ordinary tool, but a precision engineering solution for professionals who seek the highest standards in civil and industrial projects.\r\n\r\n Full description of cold cutting technology\r\n\r\n"Cold cutting" technology, which is at the heart of Daya's SDC series saws, is an advanced mechanical cutting process that is fundamentally different from traditional methods such as abrasive cutting or hydraulic shearing. Understanding these differences reveals the reason for the absolute superiority of this device:\r\n\r\nCutting process without heat and sparks: Unlike forging mills, which wear at high speed, produce intense heat (above 1000 degrees Celsius) and cause sparks and a heat-affected zone (HAZ) in the rebar cross-section, cold cutting technology uses a very hard alloy steel blade and a powerful motor with high torque and low rotation speed. This mechanism precisely and mechanically "cuts" the steel instead of burning it. The result of this process is no change in the molecular structure and mechanical properties of the steel at the cutting site, which is vital for a strong and reliable forging weld.\r\n\r\n* Creating a completely smooth and vertical cross-section surface (Mirror-Finish Surface): The precise fixer mechanism of the device keeps the rebar completely fixed and the blade creates a cut at an exact 90 degree angle with a controlled movement. The final surface obtained is completely smooth, polished and without any burrs. This feature completely eliminates the need for any secondary operations such as grinding; A process that in other methods is not only time-consuming and expensive, but can never produce the same precision as cold cutting.\r\n\r\nInternal mechanism and precision gears: One of the secrets of the durability and cutting quality of the Daya saw is the use of strong steel gears and machined with high precision in its power transmission system. This advanced design minimizes machine vibration during cutting. Vibration reduction has two key benefits: firstly, preventing premature blade failure or lipping and secondly, significantly increasing the useful life of the blade, which ultimately leads to reduced operating costs. This is the point where Chinese and domestic copies fail.\r\n\r\n Technical and operational advantages of Daya cold cutting technology\r\n\r\nUsing DAIA cold cutting saws in projects brings unique competitive advantages that directly affect quality, speed and cost.
