Milling and planing the difference! 
 First, an overview of milling: a versatile machine, milling machine can be processed in the plane (horizontal, vertical), groove (keyway, T-shaped groove, dovetail, etc.), sub-toothed parts (gears, spline shafts, chain good round, spiral-shaped surface (thread, the spiral groove) and a variety of surfaces. In addition, the surface can also be used for rotation, and to cut the hole machining work. milling machine at work, the workpiece mounted on the table or sub-degree top accessories, cutter rotation-movement, combined with the feed table or milling head movement, the workpiece to obtain the required surface finish. Because it is multi-tool intermittent cutting, milling and thus higher productivity. planer: mainly used for processing a variety of print (such as horizontal, vertical and inclined plane and a variety of grooves, such as T-shaped groove, dovetail, V-shaped groove, etc.), the surface forming a straight line if the device is equipped with profiling, but also processing space surfaces, such as the turbine impeller, spiral groove, etc. Such a simple machine tool structure, the return is not cutting, so productivity is low, generally used for single and small batch production. Second, to consider the following aspects: First: considerations from the machine works, planer knives to go cross the table and reciprocating motion, vertical milling machine table and tool, and both X, Y, Z axis, rotation to do the second: as from the processing of considerations, added to the generally planer surface-based, while clamping a single mode, while the milling machine, but can be processed plane (horizontal, vertical), groove (keyway, T-shaped groove, dovetail, etc.), sub-gear components (gear , spline shafts, sprockets good, spiral surfaces (thread, the spiral groove) and a variety of surfaces. In addition, the surface can also be used for the rotation, and to cut the hole machining work, setup is fairly complex, multi-planer The third: from accuracy considerations, planer milling machine precision is generally higher than the fourth: from the cutting tools needed to take into account the above, planer knives are generally used in hand-polished steel front made of machined surface is generally flat, while Milling cutter milling cutter as processed amorphous Fifth: From efficiency considerations, as planer by the processing object, clamping, tool impact, low efficiency, can only be used to open thick or less demanding single-piece parts processing, so the planer slowly in the machining industry would not have had while clamping flexible milling, processing of as broad, high precision, so the efficiency is generally more popular in the machining industry. VI: From the processing costs to consider, lower than the planer mill. Third, in the actual production of their main differences: planer: generally used for planing surface, the advantage lies in a straight line and flatness better than milling machines, so long the class or to the workpiece surface planer processing better and general vise mounted card can, for example, key in some tooling support, can be processed a lot of molding surface, a common machine tools in general, on the surface or in the planer processing even planing to processing gear. Milling: high efficiency, can be divided into degrees, in the processing advantages of a large surface area, and the complexity of the tool, in machining a great advantage. 
 The machine tool main drive DC motors, variable speed table speed, its wide speed range to meet the planning, milling, grinding a variety of speed requirements, a variety of materials can be processed horizontal, vertical, inclined, T-slot side rails and rack combination of advanced ultra-quenching process, so that the machine last longer. Columns, beams split feed system makes the operation more convenient and flexible. Independent oil pump lubrication system for a variety of working conditions more smoothly. VSR thermal aging increases, so that the machine more stable and durable. Planing, milling, grinding Trinity, a machine to make processing more flexible, mechanical processing, machine repair shop the best processing equipment.
