Wood Milling

Milling – machining of materials by cutting rotary cutters that are on the surface of the cutter. Cycloid is the absolute trajectory of milling. In the milling cutter and the part Procurement (future item). Milling (and themselves mills) was invented in the interval between 17 and 18 centuries ad in Germany and Austria. The first milling machine was patented by an Englishman, Eli Whitney in 1818. Milling classified according to various criteria, depending on what is allocated in the first place in the course of processing.

Classification: The shape of the surface, which describe in the space of milling cutters depending on the type of instrumental Depending on the direction of flow and position of the plane processing with respect to fiber material (in this case wood), depending on the direction of cutter rotation more detail describe each type of klassifikatsiy.Danny classification is divided into a conical, cylindrical, face, face-taper, profile frezerovanie.Pri conical milling tool axis is tilted to the treated surface, edge cutters describe a conical surface. In the process of a cylindrical milling cutters describe cylindrical surfaces with parallel work surface and the axis of rotation. Mechanical-conical milling – perpendicular to the processed surface and the axis of rotation of the cutter, is described by a conical surface. Profile milling. It is characterized by a curvilinear shape cutter blade, which describe the rotation described surface complex .Delyat at end-, face, shaped, disk. Depending on the type of instrument obtained this or that piece (or profile). End milling receive slots, grooves and undercuts, etc.

Formed different profiles, such as moldings and window frames and dr. longitudinal, cross and face milling. For the longitudinal milling is characterized by parallel to the plane of the filing and processing of fibers material for the transverse – perpendicular to the grain of the wood to the feeding direction and parallelism of the plane machined surface for face – perpendicular to the direction of feed and the machining plane fibers materiala. copropagating and counter-milling. In the first method of processing surface is cleaner, but with less performance.
