Selecting the Right Gantry Machine Center for Rail Industry Needs

Gantry machining center refers to the machining center in which the axis of the spindle Z-axis is perpendicular to the worktable, and the overall structure is a large-scale machining center machine with a portal structure frame composed of double columns and top beams, and there is a cross beam in the middle of the double column. It can perform a variety of machining operations such as milling, boring, drilling, etc., and is suitable for processing workpieces of various shapes and materials, such as molds, aerospace parts, rails, large mechanical parts, etc.

Advantages of Gantry Machine Center:

1.High rigidity and stability:the gantry structure is adopted, and the workbench and headstock are supported by large gantry beams and columns, which can withstand large cutting forces and heavy loads, ensure that the machine tool is not easy to deform during the processing process, and provide a foundation for high-precision machining, especially suitable for processing large, heavy workpieces and complex parts with high precision requirements.

2.Large processing range:the worktable is usually larger, and the stroke is also larger, especially in the X-axis direction, which can meet the processing needs of large workpieces in the length direction, and the X-axis travel of some gantry machining centers can reach tens of meters, which can realize the centralized processing of multiple processes, suitable for high-precision and high-complexity parts processing, and can also carry out one-time processing of large workpieces with complex shapes, reducing the number of clamping and error accumulation.

3.High precision: In the manufacturing process, advanced technology means such as high-precision grinding and heat treatment are adopted to ensure the high precision of the machine tool and to process parts with high dimensional accuracy and surface quality requirements. In addition, its good rigidity and stability also help to improve the stability of machining accuracy, and can maintain a high level of accuracy during long-term machining.

4.Versatility: the spindle is mostly vertically arranged, in addition to the automatic tool change device, it also has a replaceable spindle head attachment, and the functions of the numerical control device are also relatively complete, which can be used for multiple purposes, such as milling, boring, drilling, tapping and other processing processes to meet the processing needs of different types of parts.

5.Good human-computer interaction performance:The system has deeply optimized the type and accessories of the machine tool, which improves the human-computer interaction performance, machine efficiency and accuracy guarantee of the machine tool, so that the operator can operate and monitor the machining process more conveniently and quickly.

6.High reliability:most of the components are imported components, and many beds are cast by themselves, which ensures the reliability and stability of the machine tool, reduces the incidence of equipment failure, reduces maintenance costs and downtime, can run stably for a long time, and is suitable for large-scale and continuous production and processing.

7.High degree of flexibility and automation:It can be programmed according to the processing requirements of different workpieces to achieve customized processing to meet individual needs. In addition, it can also be integrated with automation equipment and production lines to achieve automated production, improve production efficiency and product consistency, help enterprises improve production efficiency, reduce labor intensity, improve product quality and market competitiveness.

Recently, the Shanghai ANTISHICNC team received a consultation from a customer in the railway industry sector in Russia (for rails). The customer’s machine requirements are:

1.The table size is 40,000 mm x 2,000 mm

2.The capacity of the worktableshall not be less than 5000 kg/m2

3.Torque is greater than 2500Nm

4.The distance from the surface of the worktable to the spindle end: the minimum is not more than 150mm; The maximum is not less than: 1300mm

5.The spindle speed is 3,000 rpm

In response to the needs of customer, I will recommend a professional DH40030 gantry machining center with large table size and high torque.
