Large Dalian double column CNC vertical lathe has a different lying car place and its matters needing attention

The car and horizontal lathe are often used in large machining. The main shaft of the car is vertical, and the bench can rotate in the horizontal range, using a vertical or oblique blade.Large vertical truck processing is mainly large diameter, short length of large or heavy workpieces, as well as horizontal lathe is not easy to clip the workpieces.If the use of horizontal lathe clip too heavy workpiece, will affect its processing accuracy, and the use of large vertical truck processing can well solve this problem.

For example, standing lathe can process disk, wheels and other cylindrical surface, can also process conical surface, end surface and so on.Vertical lathe is generally divided into two kinds, respectively are single column type and double column type.Small car is generally single column type, large car processing into double column type.In the workpiece installation, the vertical lathe adjustment is more convenient.

The main axis of the horizontal lathe is placed horizontally, can do rotary movement in the horizontal plane, the machete frame does longitudinal movement along the lathe itself, can be used to cut a variety of rotating body or internal and external threads and so on, is also a very widely used kind of lathe.

Horizontal lathe is a kind of automatic knife changing CNC lathe, for a clamp workpiece can be processed in multiple processes.The core of the horizontal lathe is the machining center, which is an efficient and automatic machining center composed of mechanical equipment and CNC system.After the end of the workpiece, the CNC system controls the horizontal lathe to choose different processes, replace the knife frame, automatic knife and so on, greatly reducing the time of the workpiece.

The selection of large truck processing process is to improve the processing efficiency and quality, so only choose a processing process accurate pass, can get the quality of the products, get more consumers and users recognized.Large vertical truck processing process is commensurate and important, its high positioning accuracy, simple and convenient operation, will not present the workpiece outside the wound environment, affect the quality of our products.

Two, what are the reasons for the early failure of the CNC vehicle and milling compound vertical lathe

The so-called early fault period is the early stage of the use of index controlled vehicle and milling composite machine tools, from the installation and debugging of the whole machine to about a year of operation. The fault in this stage is characterized by high frequency of failure and rapid decline with the increase of use time.The frequent failures in the initial use are roughly as follows:

1. Mechanical part

Although the CNC vehicle and milling composite machine tool has been running before the factory, but the time is short, and mainly for the main shaft and the guide rail.Due to the processing of parts surface with micro and macro geometry error, before completely running in, the processing surface is rough, parts assembly may have error, therefore, in the early CNC vehicle and milling composite machine tool will produce large wear, make the equipment relatively large gap between larger parts, lead to the occurrence of failure.

2. Electrical part

CNC vehicle and milling composite machine tool control system uses a large number of electronic components, although these components in the factory after a long time of aging test and other ways of screening, but the actual use, due to circuit heating, alternating load, surge current and reverse potential impact, poor performance of the test, due to current impact or voltage breakdown and scrap, or characteristic curve changes, resulting in the whole system can not work normally.

3. Hydraulic part

Due to the long transportation and installation stage after delivery, some parts of the hydraulic system are free of oil for a long time, the lubricating oil in the cylinder is dry, and the oil fog lubrication is impossible to work immediately, resulting in the hydraulic cylinder or cylinder may produce rust.In addition, if the newly installed air pipe is not clean, some debris and water may also enter the system, causing the initial failure of the hydraulic and pneumatic part.
