A router includes a motor unit and a base that receives the motor unit. A threaded shaft is supported on either the motor unit or the base. A slide is supported on the other of the motor unit and the base. The slide engages with the shaft in a first position of the slide in which micro-adjustments to a cutting depth are permitted. The slide disengages with the shaft in a second position of the slide in which macro-adjustments to the cutting depth are permitted. With a lever in a locked position, neither macro-adjustments nor micro-adjustments are permitted regardless of the slide being in the first position or the second position. With the lever in a micro-adjustment position, only micro-adjustments are permitted with the slide in the first position. With the lever in an unlocked position, the lever disengages the slide from the shaft to permit macro-adjustments.

An apparatus for precision shaving is provided. In one embodiment, the apparatus includes an endmill cutter, a base frame, and a motor adjacent to the base frame and having a shaft on one end. A coupler is positioned between the shaft and the endmill cutter. A positioning slide is housed within the base frame and a coupler frame and a first gear are fastened to the positioning slide. A second gear is adjacent to the first gear, the second gear having a set of first teeth and a set of second teeth positioned opposite the set of first teeth. The set of first teeth and the set of second teeth are separated by a gap.

Adjustable feed mechanisms, machining assemblies including the same, and associated methods. An adjustable feed mechanism includes a plurality of cam segments and a cam lifter configured to pivot each cam segment about a corresponding cam pivot point. An adjustable feed mechanism additionally includes a cam follower and a feed output assembly. The cam follower moves along the cam segments sequentially and is pivotally coupled to the feed output assembly. The cam follower pivots through a cam activation angle when moving along a given cam segment to produce the feed output. A machining assembly includes a mount assembly, a rotary element, and an adjustable feed mechanism. A method of utilizing a machining assembly to machine a work piece includes engaging the work piece with a machining assembly, positioning the tool head with respect to the work surface of the work piece, and machining the work surface.

A workpiece support device includes a shaft rotatable about a shaft rotation axis of the shaft, a first support, a first reciprocating mechanism, and a first connecting rod having one end and another end. The shaft extends along a longitudinal direction of a workpiece. The first support includes a first support roller that is rotatable about a first roller rotation axis orthogonal to the shaft rotation axis and that is configured to contact the workpiece to support the workpiece. The first reciprocating mechanism has one end connected to the first support and is configured to reciprocate in a first expansion-contraction axis direction. The one end of the first connecting rod is rotatably connected to the first support. The another end of the first connecting rod is connected to the shaft such that the another end of the first connecting rod is rotatable together with the shaft.

A floating type machining platform includes a base, a holding platform, a first elastic module, a second elastic module and a third elastic module. The holding platform is configured to hold a workpiece. The first elastic module is connected between the base and the holding platform for allowing the holding platform to move along and rotate around a first axis relative to the base. The second elastic module is connected between the base and the holding platform for allowing the holding platform to move along and rotate around a second axis relative to the base. The third elastic module is connected between the base and the holding platform for allowing the holding platform to move along and rotate around a third axis relative to the base. Wherein, the first and the second axes are different horizontal axes, and the third axis is a vertical axis.

Fixturing elements for positioning components on a work surface with a fixed or variable pitch are disclosed. The fixturing elements include a bottom portion adapted to be coupled directly or indirectly to the work surface and a top portion with a generally horizontally-extending slot or track. An insert is adapted to be positioned within the slot or track, which allows the insert to be slid or positioned at any number of positions along the slot or track. The insert may, for example, include a vertically-extending pin or a threaded hole that is adapted to receive other components. In some embodiments, the fixturing element may include an exterior side slot that opens into the slot or track, and a handle element may be inserted through the side slot and into the insert, allowing the inserted to be positioned using the handle element.
