Embodiment Construction

[0027] The specific embodiments of the invention will be further described below in conjunction with the accompanying drawings.

[0028] Step 1. Select No. 45 steel as the material of the grinding wheel hub 1, and finish machining the grinding wheel hub 1 with a diameter of Φ150mm, a thickness of 10mm, an aperture of Φ32mm, an outer peripheral surface roughness of 0.1-0.4μm, and a cylindricity of 0.002-0.005mm . Carry out degreasing and derusting treatment to the surface of the emery wheel hub 1 again, and dry it with hot air after completion.

[0029]Step 2. Install the grinding wheel hub 1 on the machine tool, select the nozzle 3 with a diameter of Φ0.3mm, fix the quenching gun in the direction perpendicular to the axis of the grinding wheel hub 1, adjust the distance between the nozzle 3 and the grinding wheel hub 1 to 5mm, and start the plasma arc For the power supply of the quenching generator, set the operating voltage of the plasma control equipment to 42V, the operati...

Abstract

The invention discloses a preparation method of an grinding wheel with a discretely reinforced hub electroplated with super hard abrasive. The preparation method comprises the steps that a nozzle of aquenching gun is moved in a wavy shape in the axial direction of a grinding wheel hub, and the temperature of materials, irradiated by plasma arc, of the external circumference surface of the grinding wheel hub is increased quickly, and decreased to form a wavy quenched zone; the quenching gun is returned to the original position, and the grinding wheel hub is rotated for an arc length around itsown axis for machining a second wavy quenched zone; the materials which are not irradiated by the plasma arc between the two quenched zones still maintain the original matrix structures; so repeatedly, till the whole external circumference surface of the grinding wheel hub forms the structure that the quenched zones and the matrix structures are arranged alternately in a wavy shape; and the grinding wheel hub discretely reinforced is electroplated with super hard abrasive to form the grinding wheel with the discretely reinforced hub electroplated with the super hard abrasive. The preparationmethod disclosed by the invention facilitates improvement of the bonding strength of the grinding wheel hub and a nickel coating, and the convergence of interface cracks is reduced; and the bearing capacity of the nickel coating is improved, and the service life of the electroplated grinding wheel is prolonged.

Description

technical field [0001] This article relates to the field of electroplated grinding wheel production, in particular to a preparation method of discretely strengthened hub electroplated grinding wheel. Background technique [0002] Electroplated grinding wheels with single-layer abrasives have obvious advantages in precision high-speed and ultra-high-speed grinding processes because of their high grinding ratio, cutting edge and grinding efficiency, easy preparation, no need for dressing, and convenient use. However, the electroplated grinding wheel uses the electroplating process to make the abrasive with a relatively uniform size wrapped on the grinding wheel hub by the metal matrix, so there is no strong chemical metallurgical bond on the metal coating, the grinding wheel hub and the abrasive joint surface, and the bonding strength is not high. The most serious problem of electroplated grinding wheel; at the same time, during the grinding process, the electroplated abrasive...
