A dual platform bed system has an associated machine for transferring material sheets from one platform bed to another. There are associated methods for both transferring and processing sheets on either or both platforms. Placing the platform beds adjacent one another reduces both human worker requirement and human and machine down time.

The invention relates to an automatic tile cutter (1) comprising a cutting table (31) for receiving a tile (21) to be cut, and at least one cutting tool (59) that is translatably movable along a guide rail (61) and is to cut the tile along a cutting line such that a cut tile and scraps are obtained, characterized in that the tile cutter additionally comprises: —at least a first conveyor (11) for conveying the tile (21) from a tile loading zone (5) to a tile cutting zone (7); —at least two abutments (15) for blocking the movement of the tile (21) in a predefined tile position in the cutting zone; and —an electronic control unit (57) configured to control the positioning of the abutment elements (15) and the cutting tool (59) relative to each other in accordance with predefined cutting parameters and actuate the cutting tool.

A drilling tool includes: a drive source; a bit attachment portion to which an end bit is attachable; a power transmission portion configured to apply a motive force to the end bit attached to the bit attachment portion; an operation portion switchable between an ON-state and an OFF-state by a manual operation and configured to receive a setting operation for setting a stop condition; and a controller configured to set the stop condition based on the setting operation, and to start driving of the drive source in response to a first switching operation for switching the operation portion from the OFF-state to the ON-state. In a state where the stop condition is set, even when the operation portion is in the ON-state, the controller stops driving of the drive source in response to the stop condition being met while the drive source is being driven.

The present invention relates to a cutting method and a cutting device for the superficial scoring of, preferably plate-shaped, components made of glass or ceramics, preferably of glass sheets, and to a method for dividing of, preferably plate-shaped, components made of glass or ceramics, preferably of glass sheets, for example of float glass sheets or laminated glass sheets, in particular laminated safety glass sheets, into individual component cuttings, preferably glass sheet cuttings.

A core drill bit 1 includes a tubular shaft 12, a mounting platform 31 provided on a proximal end of the tubular shaft 12 for mounting the core drill bit on a power tool 26, and an annular cutting section 2 provided with abrasive cutting segments 3 arranged at a distal end of the tubular shaft 12. A first transponder 24 is provided at the distal end of the tubular shaft 12. A repeater 28 is provided comprising a second transponder 29 at the proximal end of the tubular shaft 12, an antenna 33 facing the first transponder 24, and a wired connection 34 between the antenna 33 and the repeater 28.

Systems and methods for data security with power tools are provided. The systems and methods include a power tool that generates a data package, and a secure element of the power tool that generates a unique signature for the data package with a private key. The power tool transmits the signed data package to an auxiliary device. The auxiliary device receives the signed data package, and verifies the unique signature by comparing the unique signature to a public key corresponding to the private key of the power tool. With a positive verification, the auxiliary device processes the signed data package.

A processing procedure of an object in stone material and defining final profile, using: a work station of the object; tools to process the object and defining a removal thickness; a block for reciprocal movement between object and tool; a drive block control unit; an acquisition step wherein an acquisition system acquires the current cutting profile of each tool; an evaluation step wherein for each tool an offset is determined between object and tool as a function of the final profile, removal thickness and current cutting profile; and at least one processing step wherein the movement block reciprocally moves object and tool defining the offset.

The self-propelled construction machine according to the invention, in particular road-milling machine, recycler, stabiliser or surface miner, comprises a machine frame 2, which is supported by a chassis 1, which has wheels or tracks 1A, 1B. A milling drum 4 is arranged on the machine frame. The wheels or tracks 1A, 1B and the milling drum 4 are driven by a drive unit 8. Furthermore, the construction machine comprises a control unit 19 for controlling the drive unit 8 and a signal-receiving unit 18 for detecting at least one measurement variable M(t) which is characteristic of an operating state of the milling drum 4. The construction machine is characterised in that the rotational speed of the milling drum 4 is adapted, on the basis of at least one measurement variable M(t) which is characteristic of a critical operating state of the milling drum, to the operating conditions of the construction machine in such a way that the milling drum is operated in a non-critical operating state. The adaptive open-loop control of the milling drum rotational speed allows the construction machine to be operated at an optimum operating point with respect to the milling drum rotational speed.

Systems and methods for feedback features within power tools are provided. A method includes determining an operational parameter of a core drill based at least in part on sensor feedback. The sensor feedback is measured by one or more sensors disposed within the core drill. The method includes determining a feedback response to an operator based in part on the operational parameter and sending a command signal to a feedback output device. The method includes generating a feedback effect on an operator via the feedback output device, where the feedback effect comprises a change in a color of an external surface of the core drill.
