Methods of maintaining toenails of an animal that include maintaining a toenail of the animal on a surface of a trimmer head, the trimmer head being circular in configuration and including a forward end having an outside edge of a radial configuration, a rearward end, and an outer surface including an abrasive material. Air is passed through the trimming head thereby cooling the trimming head while maintaining the toenails on the surface of the trimmer head. The toenail of the animal is trimmed by grinding the toenail with the abrasive material.

The proposal is for a separating blade for the material-removing machining of a mineral-containing hard material, wherein the separating blade is designed to be set in rotation by means of a drivable flange arrangement, and wherein a liquid coolant can be supplied to the separating blade for a machining mode. According to the invention, in an inner volume of the separating blade that is surrounded by parts of the separating blade, an inner structure for providing a flow path, through which the coolant can flow, between an inlet point and an outlet point is formed in such a way that, in the connected state with the flange arrangement, an outflow of portions of the supplied coolant from the inner volume is prevented along the flow path during the machining mode of the separating blade, thus ensuring that no coolant reaches the machining section on the outside of the separating blade.

A machining toolholder including a body, a horn and a piezoelectric actuator is disclosed. The body includes a center through hole extending in the axial direction therein. The center through hole includes a first hole section and a second hole section. The horn includes a first section and a second section which are disposed coaxially and connected with each other. Part of the first section is slidably inserted into the first hole section. The second section is connected to the body and engaged with a tool. Part of the surface of the second section contacts with a wall surface of the second hole section. The piezoelectric actuator fits around the horn and is controllable to drive the tool to vibrate. With this design, the machining toolholder could have good stiffness and connection stability, and could resist to the stress effectively.

The Deburr-It Bit is a versatile tool bit designed to be used manually with smaller size circular hollow ridged tubing or with a motorized drill during the installation of all types and sizes of circular hollow ridged tubing. The function of the Deburr-It Bit is to remove burr that is formed on said tubing when the tubing is cut with various types of saws and cutting tools. In most cases, the removal of burr allows the circular hollow ridged tubing to easily slip into the manufactured fitting orifice found on all fittings which could include elbows, valves, couplings, adaptors, and most types of connectors. It should also be noted here, that removal of burr, on the inside edge of circular hollow ridged tubing, is necessary to have a smooth unrestricted surface for the best fluid flow possible. The purpose of this Deburr-It Bit is to completely remove burr from the inside edge of said tubing, the outside edge of said tubing, and release burr waste debris particles to the atmosphere at the same time during said bit rotation. What is unique is the beveled circular double-wall V-shaped abrasion cavity surfaces of the Deburr-It Bit, that when in contact with said tubing, will remove the burr from both the inside edge of circular hollow ridged tubing and outside edge of circular hollow ridged tubing at the same time and in a shorter amount of time, resulting in two smooth unrestricted tubing surfaces. There is no need for expensive machinery.

This grinding wheel tool is provided with a cylindrically shaped head unit comprising a hollow area passing through the inside, and abrasive grains adhered across the entire outer peripheral surface of the head unit. A fluid is supplied in the hollow area, and in the head unit, communication holes are formed which communicate between the hollow area and the outer peripheral surface and which, from the radial direction of the head unit, are angled forwards in the direction of rotation. Hereby, it is possible to provide a grinding wheel tool which can greatly reduce clogging even in cases where a high amount of cutting chips are generated per unit time, such as in high-feed processing.

The present disclosure provides methods of making a vitreous bond abrasive article and a metal bond abrasive article. An abrasive article preform is produced by an additive manufacturing sub-process comprising the deposition of a layer of loose powder particles in a confined region and selective heating 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 abrasive article preform produced by additive manufacturing is subsequently heated 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. Also, the methods include receiving, by an additive manufacturing device having a processor, a digital object specifying data for an abrasive article, and generating the abrasive article with the manufacturing device.
