The invention is concerned with a shielding device (1) for shielding a saw blade (3) or band of a sawing machine against access by an operator and against ejection of workpiece parts, which can be attached to the sawing machine in such a way that, in a working position, it covers the saw blade (3) or band towards the operator. The shielding device (1) comprises a temperature monitoring unit (2) which has a temperature sensor (4).

The invention is characterized in that the temperature sensor (4) operates without contact and, with the shielding device (1) mounted on the sawing machine and located in the working position, is directed towards the toothing of the saw blade (3) or band, and a display device (5) displays the surface temperature detected by the temperature sensor (4) on the surface of the toothing of the saw blade (3), wherein the temperature monitoring unit (2) is formed as an autarkic operating unit and is mounted on the shielding device (1) such that it is detachable by an operator without tools.

The invention is further concerned with a sawing machine with such a shielding device (1).

A hand-held power tool includes a guide plate including a bearing surface and a top face. A drive assembly includes a drive motor supported above the top face and configured to drive a cutting tool. An illumination arrangement is configured to emit a light cone onto the cutting tool in a direction of travel of the power tool. When the cutting tool is in a locked cutting position in which the drive assembly is locked in position with respect to the guide plate and the cutting tool projects beyond the bearing surface, the cutting tool is disposed in a light path of the light cone to generate a cast shadow of the cutting tool on an end face of the workpiece to be cut, which end face faces the cutting tool and is oriented transversely to the bearing surface of the guide plate.

A laser assisted tile cutting device consists of a base section, cutting unit, a laser beam emitting unit, a pair of guide rails, a sliding mechanism, a first mounting pad, and a second mounting pad. The first mounting pad and the second mounting pad, which are aligned parallel to each other, are perpendicularly mounted onto the base section. The pair of guide rails extend from the first mounting pad to the second mounting pad. The cutting unit is slidably positioned along the pair of guide rails via the sliding mechanism. The laser beam emitting unit generates a guided path for the cutting unit to follow. By following the guided path, accurate linear cuts and angular cuts can be obtained.

Circular saws with lock assemblies are disclosed herein. The circular saws include a motor including a motor shaft configured to rotate about a shaft rotational axis. The circular saws also include an arbor configured to operatively attach a circular saw blade to the circular saw. The circular saws further include a switch configured to selectively apply an electric current to the motor and a switch lever configured to be selectively actuated, by a user of the circular saw and via an actuation force, to actuate the switch and direct the switch to apply the electric current to the motor. The lock assemblies include a switch lock, which defines a switch-locked configuration, in which the switch lock resists actuation of the switch lever by the user, and a switch-unlocked configuration, in which the switch lever is free to be actuated by the user.

A power saw includes a bevel member and a cutting assembly pivotably connected to the bevel member. The cutting assembly includes a blade, a blade guard at least partially covering the blade, and at least one machined cutting assembly surface. A laser alignment device is connected to the cutting assembly. The laser alignment device includes a laser body fixed to a slideable carriage having a machined carriage surface that directly engages the machined cutting assembly surface. The slideable carriage is configured to move relative to the machined cutting assembly surface with substantially only one degree of freedom defined by an axis of translation.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and a lower blade guard covering a lower portion of the saw blade. The miter saw also includes a linkage for raising the lower blade guard to expose the lower portion of the saw blade as the saw unit is lowered toward the base assembly. The linkage is operable to apply a force to the lower blade guard for holding the lower blade guard in a raised position, without any input from the operator of the miter saw and without changing the length of the linkage, to facilitate changing the saw blade.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and an upper blade guard covering an upper portion of the saw blade. The miter saw also includes a cut line indicator coupled to the upper blade guard. The cut line indicator includes a light source, a cover positioned between the saw blade and the light source, a housing in which the light source is positioned, a rib coupled to one of the cover or the housing, and a first slot defined in the other of the cover or the housing. The cover includes a second slot through which light from the light source passes to illuminate opposite sides of the saw blade and a work piece supported upon the base assembly, thereby casting a shadow of the saw blade onto the work piece. The rib is receivable within the first slot to align the second slot with the saw blade.

A hand-held power tool for machining a workpiece, comprising a drive motor, a tool holder, which can be driven by the drive motor, and which is for a working tool for machining the workpiece, and a guide element having a guide surface for guiding the hand-held power tool on the workpiece in a working direction, wherein the tool holder is mounted via a bearing arrangement such that it moves relative to the guide element and the tool holder can be driven by a servo motor arrangement, wherein the hand-held power tool can be swivelled via the bearing arrangement about at least one adjusting swivel axis passing through the guide surface at an angle, in particular at a right angle, for the relative adjustment of the tool holder relative to the guide element, wherein the hand-held power tool has a control device for controlling the servo motor arrangement.

Example implementations may relate to interactive object fabrication. In particular, a control system may receive model data defining a 3D shape of a physical object that is fabricable out of a substrate at a work site. The system may then direct a projection system to emit onto the substrate a projection illustrative of the 3D shape defined by the model data. Also, the system may transmit, to a robotic system, fabrication instructions that direct the robotic system to fabricate the physical object in accordance with the model data. subsequently, during fabrication of the physical object, the system may (i) receive progress data indicative of a portion of the physical object that has been fabricated from the substrate, and (ii) direct the projection system to update the projection of the 3D shape to remove a portion of the projection corresponding to the portion of the physical object that has been fabricated.

A cutting length display device for a hand-held machine tool includes at least one display unit and a cable system unit. The at least one display unit includes at least one movably mounted display element for displaying at least one position of a cutting edge of a machining tool on a workpiece configured to be machined depending on a set cutting depth of the machining tool. The cable system unit is configured to change a position of the at least one display element depending on the set cutting depth of the machining tool.
