Abstract

An abrasive tool comprises abrasive material 3 held on the tool body 1 by a matrix 2 on whose surface is provided a wear resistant layer 4 to prevent abrasion of the matrix by particles from a workpiece when the tool is in use. The tool may be single or multipoint and used for dressing or drilling. <IMAGE>

Description

SPECIFICATION Abrasive tool This invention relates to an abrasive tool.
Abrasive tools (especially those made with diamond and cubic boron nitrode) are conventionally manufactured by encapsulating one or more abrasive particles in a resin, metal or ceramic matrix. The properties of this matrix have to be balanced between having adequate mechanical properties to retain the abrasive against the mechanical cutting loads, and having extreme wear resistance to resist abrasion by cutting debris. This dual requirement has made it necessary to use expensive matrix materials and, in the case of meal bonded tools, high processing temperatures.
Further, electro-plated tools using abrasives have in the past suffered in many applications from erosion of the electro-deposited matrix, which allows the abrasive particles to be pulled out of the matrix before the end of its useful cutting life.
An object of the invention is to allow the wear resistance of an abrasive tool to be increased.
According to the present invention there is provided an abrasive tool having a tool body, abrasive material held on the tool body by a matrix, and a layer of wear resistant material on the matrix around the abrasive material.
The abrasive material may be encapsulated in the matrix, but preferably projects from the matrix and the wear resistant layer; the matrix should have mechanical properties sufficient to retain the abrasive against mechanical cutting loads.
The matrix may be, for example, bronze, nickel, nickel alloy, iron or iron alloy. The invention allows the use of a material in the matrix having a coefficient of thermal expansion closer to that of the abrasive material than has previously been the case; this is particularly so when the abrasive material is diamond, as the alloy Invar can be used in the matrix by virtue of the invention.
The wear resistant layer may contain a secondary abrasive, preferably in a concentration of from 5 to 65% (most preferably 10 to 40%) and preferably having particle sizes of from 1 to 100 microns.
Diamond or cubic boron nitride are suitable secondary abrasives. The layer may also contain binder material, for example, a matrix of electro-less nickel (such as nickel phosphide or nickel boride) or of resin, plated nickel or plated cobalt. A solid lubricant may also be included in the wear resistant layer, for example, polytetrafluorethylene, graphite or molybdenum disulphide, preferably in particle sizes of from 0 to 100 Ft.
The wear resistant layer may be applied to the matrix by various methods. When a secondary abrasive is present, the layer may be applied by flame spraying, plasma deposition, ion plating, electro-plating or electro-less plating, and subsequent heat treatment may be required. Electro-less plating has been found to be most suitable.
An element, for example chromium, molybdenum, tungsten, aluminium, nickel or boron may be used in the layer and may be applied by solid state diffusion and subsequent heat treatment.
Ion implantation techniques may also be used to improve the properties of the surface layer of the matrix and thereby provide wear resistance.
Embodiments of the present invention will now be described by way of illustration in the following Examples, which refer to the accompanying drawings, in which: Figures 1 to 4are sectional views of portions of abrasive tools of the invention.
Example 1 The abrasive tool shown in Figure 1 has a steel tool body 1 which has applied to it a matrix 2 of nickel. Diamond particles 3 are embedded in the nickel matrix 2 to act as abrasive, and are also held by a wear-resistant layer 4 of a nickel and diamond composite. The diamond particles 3 project beyond the surface ofthewear-resistant layer 4.
The tool of this Example displays excellent resistance to abrasion of its surface by cutting debris when the tool is in use, as the layer 4 confers a great measure of wear resistance to the tool surface, while allowing the inner matrix 2 to be selected for its retention of the diamond 3.
The tool of this Example is produced by electroplating the tool body 1 with nickel around the diamond particles 3 to a depth of 0.004 inch. The matrix 2 thus formed is then coated by electro-less deposition to a depth of 0.002 inch with a composite of 75% by volume nickel and 25% by volume diamond. The diamond particles 3 in this Example are about 0.009 inch in size and therefore extend from the surface of the layer 4 by about one-third of their extent.
Examples 2, 3 and 4 Figures 2, 3, and 4 show respectively a single point tool, a multi-point tool and an abrasive drilling tool, and in each the tool body, matrix, abrasive particles and wear-resistant layer are indicated by the same reference numerals as in Figure 1. The tools of Figures 2 and 3 may be used as surface set wheel dressing tools and the tool of Figure 4 may be used as a surface set drilling bit.
While the depths of the matrix and wear resistant layers are given above only by way of example, it is preferable that the abrasive particles should project from the wear resistant layer of about one-third of their size.
Modifications and improvements can be made without departing from the scope of the invention.
1. An abrasive tool having a tool body, abrasive material held on the tool body by a matrix, and a layer of wear resistant material on the matrix around the abrasive material.
2. An abrasive tool according to Claim 1, wherein the abrasive material is particulate and projects from the wear resistant layer.
3. An abrasive tool according to Claim 2, wherein the abrasive particles project from the wear resistant layer by about one third of their size.
