hob

Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets on a hobbing machine, which is a special type of milling machine. The teeth or splines of the gear are progressively cut into the material (a flat, cylindrical piece of metal) by a series of cuts made by a cutting tool called a hob. Compared to other gear forming processes it is relatively inexpensive but still quite accurate, thus it is used for a broad range of parts and quantities.It is the most widely used gear cutting process for creating spur and helical gears and more gears are cut by hobbing than any other process as it is relatively quick and inexpensive.A type of skiving that is analogous to the hobbing of external gears can be applied to the cutting of internal gears, which are skived with a rotary cutter (rather than shaped or broached).

    Landlord Cert - Gas Hob

    When doing a Gas Landlord Safety Cert, I came across a gas hob that doesn't spark when the ignition button is pressed and therefore they tenant uses one of those spark lighter things designed for that use. Is this a safe appliance or is it AR or ID? Thanks in advance.
