improve the security of diamond saw blades
12-12
Industrial production, there is a certain risk when using a concrete saws  tool for the protection of life and attention, its security more and more manufacturers and users attention.  2.1 The new EN13236 standard  On the EN13236 standard was revised, mainly diamond saw blade bending strength criteria were refined and improved. · 2001 version of the standard: 600MPa · 2010 version of the standard refinement as follows: (1) Segment height / substrate thickness ≤ 8.5  2.2 diamond saw security - improvements 2.2.1 recipe optimization  By using low oxygen content of the feedstock powder, 200 mm diameter steel research tile pieces (blade thickness 1.6 mm, head height 7 mm) mass pull teeth strength 15 ~ 20N · m, fully meet the EN13236 standard (12.5N · m) stable European market. 2.2.2 Process optimization - laser welding
diamond cutter teeth choice
12-07
Selection of diamond tool teeth serrated teeth, in general, the concrete saws  more teeth, in the unit time, the more the cutting edge, cutting as possible, but the number of cutting teeth carbide required more and more, the high price of the blade However, serrated too close, teeth of the chip becomes smaller, easy to cause the blade fever; another jagged too, when the feed rate mis-match, then cut each tooth small amounts, will exacerbate friction with the workpiece edge, affect the life of the blade. Typically tooth spacing 15-25mm, material selection should be based on a reasonable cutting teeth.
Muela abrasiva sobre las medidas alveolares

 Muela concrete saws   sobre las medidas alveolares a continuación:  ① taladro de mano sustancialmente horizontal, de modo que el borde de corte principal para asegurar que el ángulo de borde de cincel es apropiado. Fuera de la regla de los puntos exteriores no están autorizados a Alice.Cuando ② empezar a afilar, taladro debe estar a nivel lento y constante de alimentación hacia adelante, moler detrás, formando cuchilla circular, se asegure de que el radio de borde exterior y la longitud. Si el valor es menor que el radio de filete de radio de la rueda, el taladro debe ser ligera oscilación en un plano horizontal con el fin de obtener el radio deseado.③ no debe girar hacia arriba y hacia abajo el taladro en un plano vertical, eje o sinterización de otra manera convertirse borde de cincel en forma de S, el ángulo de borde horizontal se hace más pequeño, y también es difícil de controlar la forma de un arco circular simétrica.  ④ Cuando el taladro back flip 180 ° afilar el otro lado, se debe prestar especial atención para mantener la punta del arco con la terrible simetría.
Why should cement road repair road when sawing
11-20
That's not  concrete saws , concrete pouring time in advance to be isolated from the expansion of concrete is relatively large, tiled on the road in the process of expansion and contraction easy to crack, you sawed joints is actually called expansion joints, to avoid a time of high summer temperatures caused pavement damage. In fact, you can tell if, asphalt surface at birth often muster a package, but no asphalt sawing because of the toughness of asphalt concrete pavement is far better than the cement will be expansion and contraction, if it is one, then will the whole burst occurs, so sawing a block box joints, some repaired sawn, some things are separated by casting, first, to prevent damage to the road surface thermal expansion and contraction, the second is bad good repair, because the cement pavement broken a crack will extend very far.
