Planer, it is a kind of machine tool, and is linear movement, can carry on the processing operation, but because of its low productivity, so only suitable for single piece or small batch production and processing, in mass production, are generally use milling machine instead of planer.
Planer main can be divided into shaping machine, planing machine, single arm planer and specialization planer, etc.
With single pillar, single arm planer arm planer and cantilever, the workbench vertical reciprocating motion along the lathe bed guide rail, used for machining
width is bigger and more do not need to be on the entire width of the workpieces.
Shaper it because of the slippery pillow and head shaped like a cow named, planing tool is installed on the head of the ram, a vertical reciprocating motion, is used for cutting various plane and grooves, suitable for cutting length less than 1000 mm of medium and small parts.
The characteristics of shaping machine is easy to adjust, but being single edge cutting, and cutting speed is low, don't work on the way back, so the production efficiency is low, suitable for single piece, small batch production.
Planing is commonly IT9 - precision
IT7 and the surface roughness Ra value is 6.
2 um, the main parameters of the shaper is the maximum length of the planing.
Double housing planer planing machine with a composed of top beam and column named gantry frame structure, the workbench with the workpiece through the gantry framework as a straight line reciprocating movement, used for machining large plane (
Especially the long and narrow plane)
, also used for machining grooves or at the same time a number of medium and small parts of the plane.
Large gantry planer is often accompanied by milling head and grinding etc, so we can make the workpiece in a complete after installation planer, milling and grinding plane, etc.
Double housing planer main processing large workpieces or multiple workpieces at the same time.
Compared with the shaping machine, from the point of view of structure, its form is big, complicated structure, good rigidity, look from the machine tool movement, the main movement of double housing planer is straight reciprocating motion of the workbench and feed movement is the horizontal or vertical cutter for intermittent movement, which is just the opposite with the movement of the shaper.
Planing machine driven by a dc motor, and can be stepless speed regulation, smooth movement.
Planing machine mainly used for precision machining large plane, especially long and narrow plane, can generally be planing artifacts 1 m width, length is more than 3 metres.
