Embodiment 1

[0055] A diamond mill of 300 mm, a thickness of 25 mm is prepared, and the diamond is 30 / 40 mesh for polishing the casting.

Embodiment 2

[0059] A diamond mill of 400 mm, a thickness of 40 mm is prepared, and the diamond is 30 / 40 mesh for polishing the casting.

[0060] Embodiment: Because the thickness of the grinding wheel is 40 mm, the solder used is a commercial nickel-based alloy solder having a grade BNI2, and its wetting angle is 1 °, and the maximum thickness of the solder does not flow according to the formula:

[0061] D / tan θ = 0.5 / tan1 ° = 28.7mm, the thickness of the grinding wheel is greater than the maximum no current thickness, and therefore, segmentation is required. Since the 28.7 image 3 Distant; dividing line width of 2.5 mm.

[0062] The solder flow is uniform when the diamond mill is brazed.

Embodiment 3

[0064] A diamond grinding wheel with an outer diameter of 300 mm, a thickness of 150 mm, and the diamond is 30 / 40 mesh for polishing the casting.

Abstract

The invention discloses a grinding wheel appearance with split design, its diamond grinding wheel and a preparation process. The thickness of the outer circular surface of the grinding wheel of the present invention is H, h is the maximum thickness of the alloy solder flowing and accumulating on the surface of the grinding wheel, and when H>h, a dividing zone is arranged in the circumferential direction of the outer circular surface of the diamond grinding wheel or the outer circular surface of the grinding wheel The diamond cloth area is equally divided into several small pieces; the division zone and the side length of the division pieces are blank areas, the division zone is a continuous division curve, and the division curve is a trigonometric function curve; the height of each division division in the vertical direction It is not greater than h, and the used segmentation blocks conform to the graphics of the "plane mosaic" principle. The invention creatively divides the surface of the cloth, effectively preventing the excessive flow of solder on the diamond surface; the prepared grinding wheel has high grinding efficiency and fast heat dissipation, effectively prolonging the service life and stability of the grinding wheel; the preparation process is easy to operate and low cost low, with high economic benefits.

Description

Technical field [0001] The present invention belongs to the field of manufacturing superabrasive tool, more particularly to a grinding wheel having a split design topography, diamond wheel and its preparation process. Background technique [0002] Brazed diamond wheel rotary type wheel-like structure, the main outer surface of diamond abrasive grains using the material removal process, the casting material can be effectively applied to a surface grinding burr, flash and riser like morphology, and in the field of stone processing profile grinding can be carried out, for milling and other machining marble, granite and other hard and brittle material. [0003] It is an active brazing solder using a diamond wheel containing a chemical capable of reacting with the diamond metallurgical, prepared by welding a high temperature environment in a diamond steel substrate. Grinding wheels are generally cylindrical surfaces need diamond abrasive cloth, using a cylindrical diamond and processi...
