Classified by material , the current domestic production of diamond saw
blade material matrix mainly 50Mn2V, 75Crl and 65Mn three materials , as
well as some low-end market with a 45 # steel. 45 # steel is ordinary
carbon steel , 65Mn spring steel is common , 75Crl high carbon alloy steel
. In comparison , 50Mn2V is a carbon steel , 50Mn2V fine grain size , high
thermal stability, high strength and toughness , fatigue resistance and
heat resistance. 50Mn2V saw the matrix material , with a number of complex
welding , long service life , the welding head blade easily deformed, easy
to repair after deformation , etc., as well as in the course of the
product so that the effect of high rigidity gradually , so 50Mn2V
materials are widely used in the processing and production of diamond saw
blade matrix . Classification according to specifications , the domestic
stone processing blade matrix size starting from ф200mm maximum of
ф3500mm ( foreign specifications for maximum saw blade towel 5000mm).
Which , dp200-600ram specifications mainly for trimming ( cutting edge )
processing semi-finished sheet ; ф650 above specifications is mainly used
for similar tombstone , grave stone columns and other thick (column )
forming sawing and for sawing blocks of cut ( board ) material processing.
Especially ф1600mm currently the most widely used blade matrix ф200 ~
600mm Specifications saw the matrix , due to the low technical content,
the technical and quality requirements are not high, only requires the
ability to use cutting edge on the line , the market tends to be
homogeneous product technology . Currently ф200 ~ 600mm blade matrix
specification hundreds of manufacturers , the market competition is mainly
price competition as the main means fierce competition in the industry ,
profit margins are low , some domestic enterprises do not intend to have
the strength to compete in this low-end market . Along with the increasing
emphasis on environmental protection , mining blocks scarcity of
resources, power resources in tight supply , rising GUSHI diamond polishing tools stone enterprise
manufacturing costs, increased competition , a number of energy-saving ,
resource-based , environmentally friendly saw the matrix more and more
markets welcome , customer demand for varieties blade matrix there are
some new features: 1. Sheet , thin blade -based thin sheet , thin blade
substrate sheet , the thickness of the substrate primarily to distinguish
the ф1600mm substrate normal thickness 7.3mm, 6.5mm or less in thickness
of the sheet is called substrate thickness 5.5 mm or less called ultrathin
sheet substrate . The use of thin , thin film substrate cutting blade
granite and marble slabs , can significantly improve efficiency and cut
blocks the yield , reduce power consumption , such as the GUSHI core bits for concrete use of ultra-
thin thickness of 4.0mm. Ф1600mm matrix can improve cutting efficiency
over 10% , more than 20% reduction in power consumption , increase
utilization of 16% or more blocks . As the thin , ultra-thin diamond blade
matrix thin film thickness , diameter, large deformation during heat
treatment , and thus the degree of heat treatment on the plane and HRC
control is very important. And because the GUSHI concrete diamond blades thickness of the thin end jump
to adjust the stress , comprising detecting great difficulties are caused
, in general , only by manual correction is difficult to achieve a good
level and detecting the effect .
