A device for carrying out miter cuts includes two limbs which are secured to a central element in a pivotal manner in each case and so as to be fixable in pivoted positions. Each limb has a stop strip with a contact surface, wherein the contact surface lies opposite a counter contact surface formed by a counter stop. The distance between the contact surface and the counter contact surface can be adjusted by an adjusting element. Furthermore, the limbs and the central element are made of plastic, and a region of the central element from which the guide elements originate and which extends at least over the region between the guide elements has either a metal plate or an exchangeable sacrificial plate.

The invention relates to the technical field of sawing and drilling machines, and discloses a full-automatic 45-degree sawing and drilling machine for wood board processing, which comprises a rack, negative pressure suction plates symmetrically mounted at the front and back of the upper end of the rack, auxiliary supporting plates symmetrically mounted at the front and back of the rack, a storage rack mounted on the left side of the upper end of the rack, a mounting rack mounted in the middle of the upper end of the rack, and a sliding rail mounted on the inner wall of the bottom end of the rack, and a plurality of rolling shafts which are uniformly distributed from left to right are rotationally mounted on the right sides of the front negative pressure suction plate and the rear negative pressure suction plate in a penetrating manner. The full-automatic 45-degree sawing and drilling machine for wood board processing can effectively solve the problems that in the prior art, sawing and drilling processing equipment needs to conduct sawing and drilling procedures in sequence, for wood boards needing high-precision splicing, the processing precision fluctuates due to the processing mode, the drilling position and the position degree and the coaxiality of a sawing inclined face are difficult to control accurately, and the machining efficiency is high. The defects of hole position deviation, hole wall roughness and the like exist, the high-end plate machining requirement cannot be met, and the batch machining consistency needs to be improved.

The invention relates to the technical field of wooden door pocket angled double-cutting automation equipment, in particular to wooden door pocket angled double-cutting automation equipment and a machining method. The wooden door pocket angled double-cutting automation equipment comprises a base, and a feeding and cleaning mechanism is assembled on the top of the base; the feeding cleaning mechanism comprises a first rotating rod, a first half gear, a first circular gear, a second rotating rod, a second half gear, a second circular gear, a sliding rail, a first rack, a connecting block, a supporting plate, a cutting groove, a first connecting plate, a double-end reciprocating lead screw, a sliding block and bristles. After cutting is completed, equipment drives a first rotating rod to rotate through a first motor and drives a second half gear and a second circular gear to rotate, reverse movement of a supporting plate is achieved, in the moving process of the supporting plate, a pawl drives a ratchet wheel to rotate, then through transmission of a series of gears, a double-end reciprocating lead screw is driven to rotate, and a sliding block is made to move; and the inner wall of the cutting groove is cleaned through bristles, and wood chips obtained after cleaning enter a collecting box.

The invention relates to a device for guiding a tool during the cutting of a workpiece (69), in particular a miter box, comprising guide elements (31) which define a cutting guide line (S), and comprising a base element (1), with which the tool comes into contact once the cut is completed. In order to protect the cutting edge of the tool and a base surface of the base element, one or more bodies (55) are provided, the body or bodies being rotatably arranged on the base element (1) in the cutting guide line and against which body or bodies the cutting edge can bump once the cut is completed. The body can be a rivet or a roller.

A miter gauge for guiding a work piece over a work surface of a work platform in relation to a saw blade. A fence plate is connected to a base assembly and is movable relative to a base of the base assembly to adjust the position of the fence plate relative to the base. Brackets connecting the fence plate to the base are each movable relative to the base to adjust the orientation of the fence plate relative to a first axis perpendicular to the blade in order to square the fence engaging face to the blade. The fence plate is movable relative to the two brackets to adjust the orientation of the fence plate relative to a second axis perpendicular to the work surface in order to square the fence engaging face to the work surface.
