A horizontal sawing machine includes a support unit, a driving unit, and a sawing unit. The support unit has a slide rail base with two oppositely disposed stationary slide rails. The driving unit has a driving motor, a reducing gear box, and two oppositely disposed movable slide rails. The reducing gear box is connected to the driving motor and has an output shaft. The movable slide rails are provided on the outer periphery of the reducing gear box and are respectively engaged with the stationary slide rails to enable forward and backward movement of the driving unit with respect to the support unit. The sawing unit has a saw blade and a saw blade mount connected between the bottom end of the output shaft and the saw blade so that the saw blade is rotatable by and movable forward and backward along with the driving unit to facilitate operation.

A bolt cutting apparatus including a cutter assembly and a carriage assembly attached to the cutter assembly. The carriage assembly includes a carriage housing, a tool post coupled to the carriage housing, a motor attached to the tool post, and a drive assembly configured to linearly move the tool post. The carriage assembly is configured to be secured to a structure, e.g. a flange. A cutter is attached to the motor and is disposed in the carriage housing. The motor is configured to rotate the cutter to cut a bolt on the structure, e.g. flange.

The present invention aims at eliminating a need for a moving mechanism that moves a machining table and eliminating a need for a protective cover such as a bellows cover, and includes a machining table that holds a workpiece, a machining mechanism that machines the workpiece with a rotary tool while using a machining liquid, and a moving mechanism that linearly moves the machining mechanism at least in each of X and Y directions on a horizontal plane, in which the machining mechanism moved by the moving mechanism machines the workpiece with respect to the machining table, the machining table being fixed at least in the X and Y directions.

A powered saw assembly includes a base having a top surface, a column fixed to the top surface, and a guide rail supported above the top surface. The assembly includes a saw unit translatable along the guide rail, the saw unit including a rotating arbor to which a saw blade is attachable for co-rotation therewith. A blade guard at least partially surrounds the saw blade and defines an opening through which the saw blade is movable for attaching or removing the saw blade relative to the arbor. A cover is movably coupled to the blade guard to selectively close the opening. With the cover moved away from the blade guard to expose the opening, the saw blade is attachable or removable relative to the arbor through the opening without passing the saw blade through the slot.

During an assembly process for an aircraft, segments of the fuselage are fabricated separately prior to joining the segments together to form the complete fuselage. In order to ensure that abutting ends of the segments mate together correctly, a machining process is performed along the edges of the segments at their ends. A trim-tool assembly includes an indexing cart mounted to a track secured to a surface of the workpiece, where a setting on the indexing cart varies a distance between a centerline of the track and an edge of a workpiece. The trim-tool assembly further includes a tool cart mounted to the track and translatable along the track. The tool cart includes a process tool that performs a machining process on the workpiece at a fixed distance from the centerline of the track.

The invention is a method for operating a panel saw of a framework supporting a set of beveled railings, the railings being held in a parallel and spaced apart orientation to one another and to the framework; a carriage having at least two pairs of opposing beveled carriage side edges and at least one tool securing apparatus, one pair of opposing carriage side edges reversibly removably engages the set of railings to movably locate the carriage between the set of railings; wherein the carriage moves in and out of contact with the railings through the top ends of the railings to allow the one pair of carriage side edges to be moved out of contact with the set of railings while alternately allowing the remaining pair to reversibly engage the set of railings in a manner that lets permits the carriage move along the railings in a self-centering manner.

An attachable and extendable saw and methods for cutting objects with the attachable and extendable saw are provided. The attachable and extendable saw can include a blade housing coupled to a main body. The blade housing at least partially covers a saw blade and the extendable member can be configured to move the saw blade with or without the blade housing between a retracted position and an extended position relative to the main body. The extendable saw can also include means to drive the saw blade, means to drive the extendable member, and means for attaching the attachable and extendable saw to the objects to be cut.

A saw blade for dicing a sheet of copper alloy to form individual resistors is disclosed, wherein the sheet of copper alloy has a thickness of less than 0.3 mm. The saw blade includes a ring having a first side, a second side, and a circumferential surface, wherein the thickness of the ring between the first side and the second side is less than 0.6 mm.

A saw guide for attachment to a guide post of a saw guide arbor guide assembly includes a head and a body. The head is attached to the guide post. The head includes opposed first and second head surfaces, a collar wall, and a head sidewall. The collar wall extends between the first and second head surfaces, with the collar wall engaging with the guide post. The head sidewall extends between the first and second head surfaces and defines an outer perimeter of the head. The body is attached to the head and includes opposed first and second body surfaces and a body sidewall. The body sidewall extends between the first and second body surfaces and defines an outer perimeter of the body. The saw guide further includes a lattice structure extending within at least the body, with the lattice structure extending between the first and second body surfaces.

A powered saw assembly includes a base having a top surface, a column fixed to the top surface, and a guide rail supported above the top surface. The assembly includes a saw unit translatable along the guide rail, the saw unit including a rotating arbor to which a saw blade is attachable for co-rotation therewith. A blade guard at least partially surrounds the saw blade and defines an opening through which the saw blade is movable for attaching or removing the saw blade relative to the arbor. A cover is movably coupled to the blade guard to selectively close the opening. With the cover moved away from the blade guard to expose the opening, the saw blade is attachable or removable relative to the arbor through the opening without passing the saw blade through the slot.
