Vertical Machining Centers The Working Principle Of
Sep 07, 2017

Vertical machining center: a highly automatic multi-function CNC machine with a tool base and automatic tool changing device.

Pieces on the machining center after a clamping, digital control system can control the machine tool according to different processes, automatic selection and replacement of cutting tools, automatically change the spindle speed, feed and motion trajectory of the tool relative to the workpiece and other auxiliary functions, in order to complete a few more process on the surface of workpiece processing. And there are many kinds of knives or knives, which can greatly improve the production efficiency.

Vertical machining center is to point to the state of the main shaft for vertical machining center, its structure form for fixed columns, workbench is rectangle, without dividing rotating function, suitable for processing plate, set, plate parts, it generally has three linear motion axes, and it can be installed on the workbench a along the horizontal axis rotation of the rotary table, spiral parts for processing.

Vertical machining center is easy to install, easy to operate, easy to observe the machining situation, easy to debug program, widely used. But restricted by column height and tool change device, can not machining parts, high in processing cavity or concave profile, the chip is not easy to discharge, serious when tool damage, destroy the machined surface, impact process is smooth.

Vertical machining center lubrication system in simple terms, is to separate for the lubricating oil and compressed air for mixing and form for turbulent flow of oil and gas mixture flow to the lubrication part machining center spindle part or other.

The working principle of

Using compressed air flow in the pipe, drive oil along the pipeline caused by continuous flow, mixing and transportation of oil and gas to machining center spindle part and screw other parts that need lubrication. The dry compressed air is supplied continuously with constant pressure (5-8 bar), and the lubricating oil is supplied by the different quantity of fuel consumption according to spindle lubrication, screw lubrication or other parts. So every lubrication circuit must use a separate the micro pump as the power source of the oil, the oil from the pump after must go into the oil and gas mixing valve and in oil and gas mixing valve, the flow of compressed air to blow the oil into tiny droplets, attached to the oil film is formed on the wall, the oil film with the flowing direction of the airflow in the pipe wall, medium oil film thickness in flow process gradually thinning, but not together.

feature

1. Environmental protection and pollution-free. Because there will be no oil and fog, and the surrounding environment will not be polluted. '

2. Accurate oil supply. The oil can be transported to the main shaft and screw bars by adding the control valve.

3. There is no problem of high viscosity lubricating oil atomization; Suitable for any oil product;

4. Automatic detection and monitoring. It can check whether the lubricating oil is normal, if the lubrication is bad, can stop the alarm and avoid the abnormal operation of the equipment.

5. Especially suitable for the rolling bearing of the main shaft, with certain air cooling effect, which can reduce the operating temperature of the bearing, thus extending the service life of the spindle;

6. Small consumption and cost saving.
