Disclosed are various embodiments for a table miter saw. The table miter saw allows for cross cuts, bevel cuts, as well as miter cuts and is an improvement over common table saws. The table miter saw includes a platform, orbiting base, and a telescoping assembly that allows for pushing and pulling the saw blade apparatus for mitering safety and ease of use. Additional benefits include the ability to combine multiple carpentry and woodworking tools into one compact device that is easily transferrable to the jobsite.

A device for ventilating a burning building that includes, a chassis; and a cutting assembly, mounted on the chassis. The cutting assembly is adapted to cut a ventilation hole in a roof or wall member of a building either autonomously or under remote control by an operator to allow smoke and/or hot gases to escape from the roof space.

Foldable miter saws and a folding method of miter saws are disclosed. The foldable miter saws includes a base unit, a worktable, and a cutting unit. The cutting unit includes a support arm pivotally mounted on the worktable, a saw blade, and a driver. The miter saw folding method includes the step of biasing the cutting unit relative to the base unit and the step of rotating the support arm relative to the base unit and the worktable to change the cutting unit from a working position to a folded position, thus reducing the vertical space occupied by the cutting unit and facilitating delivery, storage and package of the foldable miter saws.

A machine (1) for machining slab materials (3) is described, comprising: a working plane (2) configured to support a slab material (3) to be machined; a first tool-holder electrospindle (11) associated to a respective supporting body (33), the first electrospindle (11) and the respective supporting body (33) being supported above said working plane (2) by a respective supporting equipment (12) perpendicularly with respect to the working plane (2) and configured to move the first electrospindle (11) and the respective supporting body (33) about a rotation axis (Z) perpendicular to the working plane (2); a moving apparatus (14) configured to move the equipment (12) in parallel to the working plane (2) and along directions (X, Y) perpendicular to one another; at least a second tool-holder electrospindle (45), rotationally and translationally integral with the first electrospindle (11), supported above the working plane (2) in parallel to the first electrospindle (11) by a respective supporting arm (47) slidably supported by the supporting body (33) of the first electrospindle (11); a first actuator device (55) active to move the supporting arm (47) and the second electrospindle (45) supported by the same towards and away from the first electrospindle (11) in parallel to the working plane (2) and along a direction substantially perpendicular to a cutting plane extending perpendicularly to the working plane (2); and a second actuator device (63) associated to the supporting arm (47) of the second electrospindle (45) and configured to move the second electrospindle (45) along a direction perpendicular to the working plane (2) independently of the first electrospindle (11).

A cutting machine reduces cost increase associated with production equipment and has design flexibility for different types of batteries. A cutting machine for cutting a workpiece includes a cutting machine body including a cutting blade, a motor that drives the cutting blade, and a motor housing accommodating the motor, and an adapter including a body holder attached to the cutting machine body and a battery holder in which a battery to power the motor is installable.

A foldable miter saw includes a base unit, a worktable unit rotatably mounted on the base unit and includes an axle block, a cutting unit having a rotatable member axially mounted to the axle block, an adjusting member adjustably mounted on the axle block, and a positioning device mounted on the rotatable member. Rotating the rotatable member relative to the axle block causes the cutting unit to be shifted between a working position where the adjusting member supports the positioning device in position and the end faces of the saw blade are kept perpendicular to the work surface, and a folded position where the adjusting member and the positioning device are separated from each other and one end face of the saw blade approaches the work surface.

A work-piece securing apparatus for metal or wood working equipment, for example a miter saw, involves a support element mounted on the equipment and an elongated work-piece securing element movably supported by the support element. The support element is configured to receive and support the securing element such that the securing element retains mobility while supported on the support element to permit manual manipulation of the securing element to position the work-piece on the equipment and/or to position a work-piece engaging portion of the securing element at a desired contact point on a work-piece when the work-piece is positioned to be worked by a tool of the equipment.
