A cutting blade mounting mechanism for mounting a cutting blade to a tip portion of a spindle includes: a blade mount mounted to the tip portion of the spindle; and an air supply unit supplying air to the blade mount. The blade mount includes: a columnar boss section inserted into a through-hole provided in an annular base of the cutting blade; a flange section projecting in a radial direction from a side of a base end of the boss section and having a support surface supporting the cutting blade; and an ejector type blade suction section having a first air passage connecting a supply port supplied with air from the air supply unit and a discharge port discharging air, and a second air passage connecting a suction port opening to a side of the support surface of the flange section and the first air passage.

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.

A clamping system for machine tools includes a body portion configured to be received in a holding fixture of a machine, a tool holder integrally formed with and extending longitudinally from the body portion, the tool holder having a mounting mechanism on a distal end thereof for receiving a cutting tool, at least one fluid delivery vein extending through the tool holder from the body portion to the distal end of the tool holder, and at least one outlet at the distal end of the tool holder, the at least one outlet being configured to direct a fluid from the at least one fluid delivery vein toward at least one of the cutting tool and a workpiece.

The present invention concerns a method and an arrangement for processing calcinated carbon bodies such as anodes or cathodes for use in connection with electrolytic production of aluminium. The carbon bodies are processed using a rotating processing tool (101) that consists of a mainly circular disc with cutting edges (114) mounted at its periphery. The cutting edges may be made of polycrystalline diamond (PCD) or an equivalent material. The rotating processing tool mounted on a rotating, driven spindle and is guided by guiding elements (110) that can be jets or perforated discs that blows pressurized air at the tool, or rollers (120). With the present invention it is possible to create narrow and deep slots in calcinated carbon bodies in an efficient manner with low tool wear.

A method of processing a plate-shaped workpiece that includes layered bodies containing metal which are formed in superposed relation to projected dicing lines, includes the steps of holding the workpiece on a holding table, and, thereafter, cutting the workpiece along the projected dicing lines with an annular cutting blade, thereby separating the layered bodies. The cutting blade has a plurality of through holes defined in an outer peripheral portion thereof that cuts into the workpiece and extending through the cutting blade from a face side to a reverse side thereof, but not open at an outer peripheral edge thereof. The step of cutting the workpiece includes the step of cutting the workpiece while supplying a cutting fluid containing an organic acid and an oxidizing agent to the workpiece.

A cutting blade is held between a first flange and a second flange to define an annular cutting water supply chamber between the two flanges. The first flange has a plurality of cutting water supply holes, a first holding surface for holding one side surface of the cutting blade, and a plurality of first supply grooves formed on the first holding surface so as to extend in the radial direction of the first flange. The second flange has a second holding surface for holding the other side surface of the cutting blade and a plurality of second supply grooves extend in the radial direction of the second flange. Cutting water is supplied from the cutting water supply holes to the cutting water supply chamber and then discharged from the first supply grooves and the second supply grooves by centrifugal force due to rotation of a spindle.
