Disclosed herein is a system for substantially reducing, or eliminating, planer snipe on workpieces passing through the work area of a woodworking machine and providing a quick change out and adjustment of a press roller mounted to the hood of the woodworking machine.

A portable board mill that includes a sled, at least one ski, and at least one alignment guide. The sled may include a first end, a second end opposite to the first end, and a longitudinal axis defined between the first end and the second end, wherein the sled is adapted to engage with a router. The at least one ski also is also selectively operably engagable with the sled at one of the first end and the second end, wherein the at least one ski is adapted to engage with a work surface. The at least one alignment guide also operably engages with the sled and is moveable between the first end and the second end.

A working height adjustment device of a processing machine includes a retaining frame, a slide seat, and a lever having a connecting rod pivoted between the retaining frame and the slide seat. An adjustment seat of the slide seat has an accommodation hole. The accommodation hole is provided with an elastic member, a movable member, and an eccentric rod. The movable member has an engaging hole. The engaging hole has a diameter greater than that of a micro adjustment screw rod. The engaging hole has a toothed portion. Thereby, the eccentric rod is turned to push or release the movable member for the toothed portion of the engaging hole to engage with or disengage from a threaded section of the micro adjustment screw rod, such that the micro adjustment screw rod is tuned or the lever is pulled up and down to adjust the cutter seat quickly.

Disclosed is an intuitive electric lifting device for woodworking trimming machine, which includes an assembly base, a plurality of guide support rods, a driving motor, a screw and an intuitive control interface, wherein the intuitive control interface is electrically connected to the driving motor through a signal line. The intuitive control interface includes a casing, a display touch interface and a rotary-push button. The rotary-push button is arranged on one side of the display touch interface, protruding from the control side. The values are adjusted when the rotary-push button is rotated, and the action is executed or canceled when it is pressed. A mode status display box is provided, which specifically displays the adjusted values according to the selected control mode of the display touch interface and the rotation information of the rotary-push button in the control mode.

A planer for lumber comprises a support and at least one planing head rotatably mounted to the support. The at least one planing head has a rotation axis and is controllably shiftable to move from a first cutting position at a first axial position to a second cutting position at a second axial position. Methods and a planing head for a planer are also described.

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.
