A bearingless groove router bit includes at least one cutting element affixed to a head of the router bit and has a first end spaced from an end of connected shank connected to the head and a second end adjacent to the second end of the head. The cutting element includes a cutting edge extending along the cutting element between the first end to the second end of the cutting element. The cutting edge may include a radial side edge that projects radially inwardly relative to a central axis of the router bit and a straight side edge that extends from an end of the radial side edge outwardly relative to the central axis to minimize tear out during cutting of a groove in a work piece.

An edge milling device is provided and includes a base platform having a working surface, at least one edge milling component displaceably disposed on the working surface for processing a side surface of a target object, a positioning structure disposed on the working surface for placing the target object, and a fastening portion disposed corresponding to the positioning structure to press the target object on the positioning structure, thereby speeding up the production and improving the production efficiency.

A machining apparatus integrates a height milling device, an edge milling device and a hole forming device into a production line. As such, on the single production line, a height milling machining, an edge milling machining, a hole forming machining and so on can be performed on foot bases of a target object, such as an elevated floor, thereby speeding up the production and improving the production efficiency.

An edge trimming mechanism of an edge banding machine capable of removing scraps includes a cutting device and an air guiding cover. The cutting device includes a motor having a power outputting shaft, and a cutter mounted at an end of the power outputting shaft. The air guiding cover is hollow-shaped, installed outside the motor, and has air inlet and outlet. The power outputting shaft protrudes out of the air inlet and the cutter is at least partially located out of the air inlet. An air exhausting path is defined between the inner wall of the air guiding cover and the outer wall of the motor. Two opposite ends of the air exhausting path communicate with the air inlet and outlet respectively. By the above-described configuration of the edge trimming mechanism, it is effective in removing the scraps produced by the edge banding machine in the edge trimming process.

Provided are a deburring tool and a deburring apparatus capable of, when the contact angle between the deburring tool and a workpiece changes, following the portions to be deburred, and thus always capable of performing uniform deburring against contraction, deformation, and strain of resin products.

A deburring tool includes a nav. tool 9 in which a cutting tool 7 is inserted and fitted and that has an opening 41 exposing a blade portion of the cutting tool 7, opening edge portions 42 and 43 of the opening 41 each include a profiling guide portion 45 expanding, in the circumferential direction of the profiling guide member, in a sector shape that is centered on the center axis of the nav. tool 9, and the profiling guide portion 45 is formed to have a conical shape in side view.
