large diamond saw blades

 1 product heat treatment method: This large-size saw the matrix heat treatment, currently there is no special equipment, we use a unique heat treatment process, a good solution to large size, thin thickness of the core bits for concrete  base body heat problems, can better control the hardness HRC38 ± 3 range improved blade stiffness matrix, increasing the life of the product.(2) processing methods: face grinding also saw the matrix product processing difficulties. We have developed a white surface grinder lathe, very clever solution to this problem, the product thickness tolerances can reach the national standards, greatly improving the static balance indicators, in addition to material due to surface oxidation layer and decarburization, product fatigue life greatly improved.3 blade cutting process for chip removal mining practical difficulties, the company also made a matrix shape bold exploration: We saw the matrix using varying amounts of the appropriate parts machining holes hollowed out, does not affect the overall strength of the blade under the premise of improving the cooling BTA efficiency, extend the blade life and reduced energy and mining blocks shorter time.Fourth, with the  flap discs traditional way of exploitation of comparative economic and technical indicators
New mining methods applied to improve the resource utilization rate of extraction, the exploitation of quality improvement, a corresponding increase in value-added products. Reduce production costs, while overcoming the traditional way of exploitation of poor safety performance exist, serious damage to the environment and other shortcomings, has great economic social benefits. Fifth, use requirements1 Before Installation(1) saw the 4 inch saw blades  track laying claim sleepers solid formation, saw cutting process in order to avoid shaking, saw the track parallelism tolerance to ≤ 5mm, the level of tolerance ≤ 2mm.(2) In order to ensure flatness of the blade during cutting strength, the saw blade clamping flange diameter> i280ram, roughness flange side jump directly affects the blade. Therefore, the user should check before using flange accuracy, it is not generally Ф280mm flange flatness <0.05mm, and ensure clean flange must not remain stone chips dirt.(3) regular testing Saw axis accuracy, and ensure its spindle runout ≤ 0.03mm, in order to avoid the blade cutting process produces jitter, affecting the quality of life of saw blade material cutting.(4) cooling water directly affects the size blade cooling effect, chip capacity blade cutting life. Therefore recommended Ф2000 (or Ф2200) cooling water ≥ 1001/min, Ф2800 (or Ф3000) cooling water ≥ 1601/rnin, and fully injected into the blade cutting seam.
