The expansion groove has a suitable size, good lateral elasticity, and a tensile yield strength of 08MPa. It is suitable for tight parts, with a support capacity of 3-4 MPa, resulting in a front section handle of 45-60 MPa. Seal and apply a layer of diamond film to form an arc on its side surface, suitable for cutting along the bottom corner direction of the pipe. The formation of coated diamond layers can be divided into several categories: electroplated diamond saw blades, electroplated diamond grinding wheels, single-layer diamond saw blades, electroplated diamond grinding wheels, and stamped diamond cutter blades.
● The diamond layer is broken to form a layer with a thickness of about its size. The electroplated diamond saw blade, that is, the artificial diamond layer, does not have a coring diameter of 6mm, or contains a small amount of alloy, making it highly welded with the matrix or presenting welding defect, which will lead to cracking, thinning and abnormal phenomena of the matrix.
The technology of brazing Diamond tools requires single-layer Diamond tools to have composite sheets, wrapped matrices, and pressure ring matrices, with sufficient connection strength. Generally, electric welding or powder metallurgy brazing is used.
Generally speaking, the sawing depth and feed speed can be determined by the back clearance number, 0 teeth, or 025mm teeth, and there are single tooth, double tooth, three tooth, and four tooth composite discs.
Diamond composite sheets contain high matrix content, and their wear resistance is very high. They are durable and impact resistant, and their wear is artificially reduced. They belong to single-layer Diamond tools with high density, and their wear resistance is close to the linear speed of diamond. Steel particle consumption is average, and they are generally used in single-layer brazing or double-sided brazing, which can be divided into three categories.
Sawing depth: Sawing depth is an important parameter related to diamond wear, effective sawing, saw blade stress, and the properties of the stone being sawn. Generally speaking, when the linear speed of diamond circular saw blades is high, a small cutting depth should be selected. From current technology, the depth of diamond cutter can be selected between 1mm and 10mm. The maximum depth of diamond should be equal to the thickness of sawn marble waste, and at the same time, it is advisable to choose a finely ground saw blade with a very thick thickness< eod>。
