What is the working principle of ordinary milling machine?

When the milling machine is working, the workpiece is mounted on the accessories such as the workbench or the indexing head, and the rotation motion of the milling cutter is the main motion, supplemented by the feeding motion of the workbench or the milling head, so that the workpiece can obtain the required machining surface. Because it is multi-tool intermittent cutting, the productivity of milling machine is high. A machine tool for milling workpieces with a milling cutter. Milling machines can not only mill planes, grooves, gear teeth, threads and spline shafts, but also process more complex contours, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments.

First of all, according to the layout form and scope of application to distinguish.

(1) lifting table milling machine: universal, horizontal, vertical, etc. , mainly used for processing small and medium-sized parts, the most widely used.

(2) Gantry milling machine: including gantry milling and boring machine, gantry milling and planing 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 can feed longitudinally; The vertical milling head of the latter can move horizontally along the cantilever guide rail, and the cantilever can also adjust its height along the column guide rail. Both of them are used to process large parts.

(4) Milling machine without lifting table: there are two kinds of rectangular table and circular table, which is a medium-sized milling machine between lifting table milling machine and 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 for processing instruments and other small parts.

(6) Tool milling machine: used for the manufacture of molds and tools, equipped with various accessories such as vertical milling head, universal angle workbench, plugging head, etc., and capable of drilling, boring and slotting.

(7) Other milling machines: such as keyway milling machine, cam milling machine, crankshaft milling machine, roller journal milling machine, square ingot milling machine, etc. It is a special milling machine for machining corresponding workpieces. Milling machines are divided into copying milling machines (see copying machine tools), program-controlled milling machines and CNC milling machines (see CNC machine tools) according to control methods.
