Advantages of Xiaolongmen over Dalijia

One. Under what circumstances can we consider purchasing a gantry machining center?

1. The workpiece to be processed has exceeded the common C-shaped junction standard in the market, so it is necessary to consider buying a gantry machining center.

When processing large workpieces, it is necessary to choose the C-type vertical machining center according to the market standards, and the gantry machining center should be considered.

When mold processing or large surface processing requires heavy cutting or when the workpiece is particularly heavy, the gantry machining center will be your best choice.

4. The company has developed to a certain extent, and the demand for procurement has become more hierarchical. The Longmen Processing Center will enhance your company's image to a higher level.

2、 What is the structure of a vertical machining center?

1. Vertical machining centers are commonly referred to as C-type machining centers.

2. Basic X/Y/Z three motion axes, single column, with column counterweight and spindle box lifting structure.

III. Why is it better to buy a large vertical machining center than a gantry machining center?

1. With the development of numerical control machine tools around 2000, the manufacturers of numerical control machine tools in Chinese Mainland have been expanding overnight. After several years of development, the feeling of CNC machine tools is no longer particularly mysterious and advanced. Especially in developed regions, CNC machine tools are only a commonly used tool for improving production power and processing accuracy, and reducing valuable labor. After several years of development, the number of companies using several, dozens, and even hundreds of processing centers can be said to be countless. The ultimate result is that the processing costs are getting lower and lower. Peer runs on each other have led to many companies without core competitiveness ultimately facing closure and closure. So how can enterprises showcase their talents in such fierce competitions? Nowadays, the polarization in the market is becoming increasingly prominent, with either higher equipment standards or extremely low equipment standards. By relying on output value, companies have a way to survive.

2. The machining center of the gantry machining center is an extension standard after the C-shaped construction. The notable features are large size, strong rigidity, higher flexibility, and more convenient clamping.

So there are fundamental differences between C-shaped and gate shaped structures, let's analyze their differences!

(1) The C-type vertical machining center adopts a single column structure, while the gantry machining center adopts a gate structure with double column supports and moving crossbeams. So the structure of the gantry machining center becomes thicker, more rigid, and has greater cutting force

(2) In order to satisfy the machining of large parts, it is necessary to make the distance between the spindle and the column very large in the C-type vertical machining center, causing structural instability. The construction of the gantry machining center adopts an ultra short spindle throat extension, with a spacing shortened by 70% compared to the vertical machining center. Moreover, the spindle center of the gantry machining center and the Z-axis lifting guide rail are fundamentally in a straight line. So this structural feature is the ability to complete heavy cutting without causing a sensation in the machine tool.

(3) The cross shaped construction workbench selected for the C-type vertical machining center results in uneven friction coefficient and low positioning accuracy. And the workload of the workbench will significantly decrease. When the workbench moves fully on the pallet, both ends of the pallet must be suspended. If heavy cutting processing is to be completed at both ends and suspended for years, the accuracy and service life of the machine tool will also be greatly shortened.

(4) The counterweights of the C-type vertical machining center are all counterweights. At the moment of lifting and lowering, due to the Gravitational acceleration G, the instantaneous change of counterweights affects the accuracy. The gantry machining center uses a dual cylinder nitrogen counterweight, which is much stronger in reaction than the former. In this case, the movement of the gantry machining center should be more stable, and the machining accuracy will be higher.
