There are many types of milling machines. Currently, there are horizontal lifting table milling machines and vertical lifting table milling machines.
(1) Horizontal lifting table milling machine
This type of milling machine is divided into horizontal lifting table milling machine, universal lifting table milling machine and universal rotary head milling machine. One of their common features in the structure is that in addition to the longitudinal and lateral movement of the table, it can also move vertically up and down with the lifting table. The disadvantage is that the rigidity of the lifting platform is poor, so it is not suitable for processing extra large. Workpieces and heavy heavy cutting.
1. Horizontal Elevator Milling Machine The main shaft of this milling machine is horizontal (horizontal). The workpiece to be machined is fixed on the table. Through the moving parts such as the lifting table and the table, the workpiece can be fed vertically, horizontally and vertically, while the milling cutter performs a rotating cutting motion. This type of milling machine is widely used for machining planes, grooves and forming surfaces.
2. Universal lifting table milling machine It is basically the same as the horizontal lifting table milling machine except that it has one more rotating disk. That is, the table base of the horizontal lifting table milling machine is divided into two parts, one is a rotating disk and the other is a bed saddle. The turntable can be rotated by plus or minus 45° on the saddle (ie, 45° to the left or right). Therefore, in addition to the various milling operations of the horizontal lifting table milling machine, the milling machine can also mill workpieces such as spiral grooves and helical gears.
3. Universal rotary head milling machine Its lifting platform and bed part are exactly the same as the universal lifting table milling machine, except that the top cantilever beam is equipped with a separate motor and gearbox to drive the universal milling head at the front end of the cantilever beam. The universal milling head can be rotated at an angle in the vertical plane and in the horizontal plane. The spindle of the milling machine can be used alone or in combination with a universal milling head for multi-blade multi-blade machining. Therefore, in addition to the various processing of the universal lifting table milling machine, the milling machine can also be used for drilling, reaming, boring and inclined hole processing, which greatly improves the versatility of the lifting table milling machine.
(2) Vertical lifting table milling machine
The structural feature of this type of milling machine is that the main shaft is vertically placed and can be rotated 45° to the left or right in the vertical plane of the longitudinal direction. The lifting table and feed system of the vertical lifting table milling machine are the same as the horizontal lifting table milling machine.
Vertical lifting table milling machines have a wide range of machining, and face milling and end milling cutters can be used for surface milling of planes, bevels, grooves and angles.
