It is distinguished according to the layout form and scope of application
1. Lifting table milling machine: there are universal, horizontal and vertical type, etc., which are mainly used for processing small and medium-sized parts, and are the most widely used.
2. Gantry milling machine: including gantry milling and boring machine, gantry milling machine and double-column milling machine, all of which are used to process large parts.
3. Single-column milling machine and single-arm milling machine: the horizontal milling head of the former can move along the column guide rail, and the workbench is longitudinally fed; the end milling head of the latter can move horizontally along the cantilever guide rail, and the cantilever can also adjust the height along the column guide rail. Both are used to machine large parts.
4. Workbench does not lift milling machine: there are two kinds of rectangular workbench type and round workbench type, which is a medium-sized milling machine between the lifting table milling machine and the gantry milling machine. Its vertical movement is completed by the lifting of the milling head on the column.
5. Instrument milling machine: a small lifting table milling machine used to process instruments and other small parts.
6. Tool milling machine: used for mold and tool manufacturing, equipped with a variety of accessories such as end milling heads, universal angle tables and plugs, etc., and can also be used for drilling, boring and inserting.
7. Other milling machines: such as keyway milling machines, cam milling machines, crankshaft milling machines, roll journal milling machines and square steel ingot milling machines, etc., are special milling machines manufactured for processing the corresponding workpieces.
By structure
(1) Desktop milling machine: a small milling machine used for milling small parts such as instruments and meters.
(2) Cantilever milling machine: the milling machine with the milling head mounted on the cantilever is horizontally arranged on the bed, and the cantilever can generally move vertically along the column guide rail on one side of the bed, and the milling head moves along the cantilever guide rail.
(3) Ram milling machine: a milling machine with a spindle mounted on a ram.
(4) Gantry milling machine: the bed is horizontally arranged, and the columns and connecting beams on both sides of it constitute a milling machine for the gantry. The milling head is mounted on the beam and column and can be moved along its rails. Usually the beam can be moved vertically along the column guide rail, and the worktable can move longitudinally along the bed guide rail, which is used for large-scale processing.
(5) Surface milling machine: a milling machine used for milling planes and forming surfaces.
(6) Copy milling machine: a milling machine for copy processing of the workpiece. It is generally used for machining workpieces with complex shapes.
(7) Lifting table milling machine: a milling machine with a lifting platform that can move vertically along the bed guide rail, and the workbench and saddle usually installed on the lifting platform can be moved longitudinally and transversely respectively.
(8) Radial arm milling machine: Radial arm milling machine can also be called turret milling machine, radial milling, universal milling, the turret milling machine of the machine tool is a light general metal cutting machine tool, with vertical and horizontal milling two functions, can mill the plane, inclined plane, groove and spline of small and medium parts.
(9) Bed-type milling machine: the workbench can not be lifted, and can be moved longitudinally and transversely along the guide rail of the bed, and the milling head or column can be used as a milling machine that moves vertically.
(10) Special milling machine: such as tool milling machine: a milling machine used for milling tools and molds, with high machining accuracy and complex processing shapes.
According to the mode of control
Milling machines can be divided into copy milling machines, program control milling machines and CNC milling machines.
