The Advantages and Disadvantages of the Longmen Processing Center and the General Processing Center Are Contrasted with the Whole

Longmen processing center is mainly used for processing large parts, Longmen processing center is called the terminator of large vertical processing center, compared with the ordinary processing center, the longmen processing center has unique structural characteristics, this processing center refers to the spindle axis and workbench vertical set of the processing center.

Its special structure:

1. Workbench, bed body, columns, beams and other major components.

The workbench of the Ganmen Processing Center is basically rectangular. In order to ensure the stability of processing accuracy and extend the service life of the machine tool, the large castings such as the workbench, bed body, column, beam and slip pillow of the gantry processing center use Mihanna cast iron, casting inner cavity series beehive composite arrangement structure, advanced design, are time-sensitive and secondary tempering treatment, eliminating residual internal stress to stabilize the material.

2. Ganmen.

The composition of the gantry consists mainly of a beam and two columns. It is divided into three types: beam fixing, beam locking segment lift by positioning block and arbitrary lift of beam.

3. Slide pillow.

The slip pillow can be divided into open and closed types from the structure. The open-type slide pillow is clamped on the spindle box by the press plate, the cut-off area of the slip pillow is large, the slide pillow of the closed structure is clamped in the spindle box, and the space area of the slip pillow is small.

4. Knife library.

Knife library is an important component of the machine tool, with automatic tool change function, its basic type has the turret type, drum type and chain length three.

5. Attachment head library.

Machining of large and complex parts usually requires many attachment heads. The attachment head is specially designed according to the processing requirements of the workpiece, and is generally divided into right angle head, extended head, special angle head and universal head.

Compared with ordinary machine tools, that is, the trip of the Longmen processing center is more than 1000mm, so large-scale workpieces can be processed.

The CNC Ganmen Processing Center has the following advantages and disadvantages: 　　

1. Benefits: 　　

(1) The precision of the Longmen processing center is relatively high, with a relatively high processing quality; 　　

(2) multi-coordinate linkage can be carried out, can be machined into a more complex shape parts; 　　

(3) when processing parts change, usually as long as the numerical control procedures, so as to save production preparation time; 　　

(4) Longmen processing center its own high precision, rigidity, can choose a favorable processing amount, productivity will be higher; 　　

(5) The degree of automation of the Longmen processing center is relatively high, which can reduce the intensity of labor; 　　

(6) batch production, the quality of the product is easy to control.　

2. Cons: 　　

(1) The quality requirements of the operators of the Longmen processing center are relatively low, and the technical requirements for maintenance personnel are relatively high. 　　

(2) Processing route is not easy to control; 　　

(3) maintenance is not convenient, the technical requirements are relatively high; 　　

(4) The process is not easy to control.

And the large footprint, high manufacturing costs, expensive, and the operator in the process of debugging the gantry frame blocked the operator's view, the operator operation observation caused a great obstacle, in the workpiece clamping, knife, workpiece measurement, machining tool track observation and many other operations inconvenience.

In summary, the Longmen Processing Center is more suitable for processing large parts, such as automobiles, ships, train industry large parts.

Many customers who process large parts are happy to choose the Ganmen Processing Center.
