The difference and connection between vertical machining center and horizontal machining center

Vertical Machining Center

Vertical machining center refers to the machining center with the main shaft in a vertical state. Its structure is mostly fixed columns, the worktable is rectangular, and there is no indexing and rotating function. It is suitable for processing discs, sleeves and plate parts. It generally has three linear motions Coordinate axis, and a turntable that rotates along the horizontal axis can be installed on the worktable to process helical parts.

The vertical machining center is easy to install, easy to operate, easy to observe the processing situation, easy to debug the program, and widely used. However, due to the limitation of the height of the column and the tool changing device, parts that are too high cannot be machined. When machining a cavity or a concave profile, the chips are not easily discharged. In severe cases, the tool will be damaged, the machined surface will be damaged, and the smooth processing will be affected. .

working principle

The flow of compressed air in the pipeline is used to drive the continuous flow of lubricating oil along the inner wall of the pipeline, and the oil and gas are mixed and transported to the main shaft part of the machining center and the lead screw and other parts that need to be lubricated. The dry compressed air is continuously supplied at a constant pressure (5-8BAR), and the lubricating oil is supplied quantitatively according to the different quantities of spindle lubrication, screw lubrication or other parts of the oil consumption. Therefore, each lubrication circuit must use a separate micro oil pump as the power source for oil delivery. After the oil comes out of the pump, it must first enter the oil-air mixing valve. In the oil-air mixing valve, the flowing compressed air blows the oil into small oil droplets, which adhere to the An oil film is formed on the pipe wall, and the oil film flows along the pipe wall with the direction of the airflow, and the thickness of the oil film gradually decreases during the flow process, but does not condense.

Features

1. Environmental protection and no pollution. Because there will be no oil pollution and mist spray, the surrounding environment will not be polluted'

2. Oil supply. The oil can be delivered to the lubrication points such as the spindle and the lead screw according to different needs by adding a regulating valve;

3. There is no problem of difficult atomization of high-viscosity lubricating oil; it is suitable for any oil;

4. Automatic detection and monitoring. It can detect whether the lubricating oil is normal. If the lubrication is poor, it can alarm and stop to avoid the abnormal operation of the equipment.

5. It is especially suitable for the rolling bearing of the main shaft, which has a certain air cooling effect, which can reduce the operating temperature of the bearing, thereby prolonging the service life of the main shaft;

6. Low fuel consumption and cost saving.

Horizontal machining center

Horizontal machining center refers to the machining center whose main shaft is in a horizontal state, usually with a rotary table with automatic indexing. After one card installation, complete the processing of the remaining four surfaces except the mounting surface and the top surface, it is most suitable for adding box parts. Compared with the vertical machining center, the horizontal machining center is easy to remove chips during machining, which is beneficial to the machining, but the structure is complex. The price is higher.
