A milling module for a key cutting machine, the module comprising a first rotary cutter and a second rotary cutter. The first and second rotary cutters each include a gear and a shaft projecting from the gear. The shaft includes one or more cutting blades. The milling module further comprises a housing configured to locate the gears of the first and second rotary cutters, such that the gears of the first and second rotary cutters are arranged in a gear train.

A key cutting machine is provided. The key cutting machine comprises a rotary cutter, an anvil and control circuitry. The rotary cutter is for cutting into the blade of a key blank. The anvil is for stabilising the key blank whilst the rotary cutter is cutting the key blank. The control circuitry is configured to: cause at least one of the anvil or the rotary cutter to move, such that the anvil is located substantially at a first face of the blade of the key blank and the rotary cutter is located substantially at a second face of the blade of the key blank, the second face of the blade of the key blank being on an opposite side of the blank to the first face; and cause the rotary cutter to cut into the second face of the blade of the key blank.

A three-dimensional shaping method including the steps, after a lamination step, in which steps of forming a powder layer, flattening with a squeegee and sintering are repeated, followed by cutting of the surface of the laminate, 1. setting the overall shape of an object to be shaped by a CAD/CAM system, and setting machining units that form the overall shape and cutting allowances on peripheral sides and upper sides of each of the machining units, 2. cutting of the peripheral sides and upper sides according to a prescribed order, after lamination with addition of a cutting allowance on the peripheral sides of each machining unit, and after carrying out lamination to the thickness of the cutting allowance on the upper side of the machining unit and the machining unit adjacent above the machining unit, and 3. continuing repetition of step 2, from the lowest to the topmost machining unit.

Disclosed herein is a cyclonic system for performing subtractive machining in microgravity systems. The cyclonic system comprises: an enclosure, a blower, and a debris collection module to collect the debris from the milling machine. The enclosure includes a top plate, a base plate, and a tapered side wall joining the top plate to the base plate. The enclosure defines a chamber to house a milling machine having a cutter tool. The blower generates an airstream that induces a cyclonic airflow to achieve cyclonic separation of debris within the enclosure. In operation, the cyclonic airflow urges the debris from the milling machine toward the base plate and into the milling machine.

A trimming device of the edge banding machine includes a mounting assembly attached to a fixing assembly, a wheel assembly mounted to the mounting assembly and having a first wheel rolled on a top surface of a to-be-processed workpiece and a second wheel rolled on an edge band adhered to a lateral side of the to-be-processed workpiece, a moving scraper unit including a feeding and retracting assembly having a slider slidably mounted on a slide groove of the mounting assembly, and a scraper assembly mounted on the feeding and retracting assembly and having a scraper, and a retractable rod driving the moving scraper unit to move along the slide groove. Through movement of the moving scraper unit and action of the retractable rod, the scraper maintains constant contact with the edge band to solve a problem of over-trimming or instability of the front and rear ends of the edge band.
