A sheet sticking apparatus includes a sticking unit that sticks a sheet to a workpiece held by a chuck table and a cutting unit that cuts the stuck sheet. The cutting unit includes a cutting blade that cuts the sheet, a movement unit that raises and lowers the cutting blade from and toward the chuck table or moves the cutting blade along the outer circumference of the workpiece, and a cleaning part that removes adhering things of the cutting blade. The cleaning part is disposed on the trajectory of the cutting blade that moves by the movement unit and executes cleaning by coming into contact with the cutting blade that moves.

The present teachings include techniques for regulating the temperature of coolant used for a wet saw and the like. That is, a wet saw usually accommodates a coolant tank and/or tray, where coolant is pumped therefrom to the saw blade and/or an interface between the saw blade and a material to be cut (e.g., tile), e.g., to lubricate and cool the saw blade. However, when using a wet saw in colder environments, freezing can be a problem. While submersible “bucket heaters” and the like may be used, these heaters can be cumbersome, faulty, and dangerous. Therefore, the present teachings may include a reservoir with an integrated heating element that is built into the tank/tray itself (e.g., within its base), such that the heating element is physically isolated from the coolant contained therein. Such a heated reservoir may be retrofitted onto an existing saw and/or fabricated with the saw itself.

A pipe drilling device includes a casing having a divided structure and externally fitted to a fluid pipe in a sealed manner, a process valve including a process valve body that comes into contact with and separates from a recessed valve seat portion provided inside a neck portion of the casing, a drilling machine including a cutter that is inserted into the casing and configured for drilling the fluid pipe in an uninterrupted flow state, and a cylindrical portion that is movable to open and close an opening of the recessed valve seat portion inside the neck portion.

The invention relates to a method for separating a plurality of slices from workpieces (4) by means of a wire saw, wherein a wire grating (2) is tensioned in a plane between two wire-guiding rollers (1), wherein each of the two wire-guiding rollers (1) is mounted between a fixed bearing (5) and a floating bearing (6). The method involves delivering the workpiece (4) via the wire grating (2) by controlling the temperature of the workpiece (4) by wetting the workpiece (4) with a cooling medium, while simultaneously axially shifting the floating bearing (6) by controlling the temperature of the fixed bearing (5) with a cooling fluid according to the specification of a first temperature profile, and while simultaneously shifting the workpiece (4) along the workpiece axis by means of a control element (15) according to the specification of a second correction profile.

A tool for local cooling by contact of a glass sheet at a temperature higher than 450° C., known as a contact tool, includes a contact face suitable for coming into contact with the glass sheet, the tool including an internal pipe for the circulation of a coolant, in particular air. The tool is used in a device for bending and/or cooling a glass sheet, in particular individual, the tool coming into contact with the glass sheet while it is held by a bending tool or by a cooling frame after bending. A compression zone is created that is capable of being drilled to form an edge having compressive stresses.
