A method for producing a tool with a diamond-studded tool head includes the steps of providing a tool shank and fixing a support element to a free end of the tool shank. The method further includes the steps of applying a layer of material interspersed with diamonds at least in sections to the support element and to a section of the tool shank adjoining the support element, and at least partially removing the support element, so that the layer of material interspersed with diamonds forms a tool head which in cross-section has the form of a circular ring and has a front-side recess.

A method for distributing a coolant to a grinding site of a grinding wheel, including rotating the grinding wheel, injecting the coolant in an inlet of the grinding wheel disposed proximate to an axis of rotation of the grinding wheel, moving the coolant fluid from the inlet along a plurality of internal grooves of the grinding wheel outwardly towards a plurality of outlets, and expelling the coolant outwardly from the plurality of outlets at an angle of at most 15 degrees with respect to a tangent to a circumference of the grinding wheel at the outlet.

A tool-cooling mechanism includes a grinding tool. The grinding tool is provided with a converging disc, and the converging disc rotates with the grinding tool to draw external cooling water into the grinding tool for convergence, and then radially conveys the cooling water as converged toward an inner wall of the grinding tool, such that the cooling water can flow to a grinding surface along the inner wall of the grinding tool. The cooling water is allowed to enter via a water inlet and cool the grinding surface smoothly even when the grinding tool is rotating at a high speed, such that the cooling water can be prevented from passing through the grinding tool axially and failing to cool the grinding surface. In addition, the grinding surface is cooled after the cooling water as dispersed and atomized by the rotation of the grinding tool is converged.

A grinding tool and a manufacturing method thereof are disclosed. The grinding tool includes a plurality of thin teeth (2) which are sequentially spliced and stacked to form an annular structure, wherein every two adjacent thin teeth (2) are fixedly connected, and a groove body (4) is formed between every two adjacent thin teeth (2). The narrower and the more the groove bodies of the grinding tool are, the better the cooling effect is, thus the better the chip-removal effect is. Meanwhile, the manufacturing method for the grinding tool features a machining process having low difficulty and is easy for mass production, thereby facilitating the high-speed and high-efficiency machining of grinding tools with an organic bond and an inorganic bond.

The present disclosure provides methods of making a vitreous bond abrasive article and a metal bond abrasive article. The methods include sequential steps. Step a) includes a subprocess including sequentially: i) depositing a layer of loose powder particles in a confined region; and ii) selectively applying heat via conduction or irradiation, to heat treat an area of the layer of loose powder particles. The loose powder particles include abrasive particles and organic compound particles, as well as vitreous bond precursor particles or metal particles. The layer of loose powder particles has substantially uniform thickness. Step b) includes independently carrying out step a) a number of times to generate an abrasive article preform comprising the bonded powder particles and remaining loose powder particles. Step c) includes separating remaining loose powder particles from the abrasive article preform. Step d) includes heating the abrasive article preform to provide the vitreous bond abrasive article comprising the abrasive particles retained in a vitreous bond material, or to provide the metal bond abrasive article. A method of making a metal bond abrasive optionally includes infusing an abrasive article preform with a molten lower melting metal and solidifying the molten lower melting metal to provide the metal bond abrasive article. The present disclosure further provides a vitreous bond abrasive article precursor and a metal bond abrasive article precursor. Also, methods including receiving, by a manufacturing device having a processor, a digital object specifying data for an abrasive article, and generating the abrasive article with the manufacturing device.
