Gantry machining center refers to a machining center set perpendicular to the spindle axis and workbench, mainly suitable for processing large parts.

1 Workbench

The workbench of the gantry machining center is basically rectangular. Large castings such as workbenches, bed bodies, columns, crossbeams, and sleepers are made of Mihanna cast iron. The inner cavity of the castings is a honeycomb composite arrangement structure, with advanced design and all have undergone aging and secondary tempering treatment to eliminate residual internal stress and stabilize the material, ensuring the stability of workpiece processing accuracy and machine bed life.

2 Gantry

The gantry is composed of a crossbeam and two columns. It can be divided into three types: fixed crossbeam, segmented lifting of crossbeam locked by positioning blocks, and arbitrary lifting of crossbeam.

3 ram

The ram can be divided into two types structurally: open and closed. The open structure of the ram is clamped onto the spindle box through a pressure plate, resulting in a large cross-sectional area of the ram; The closed structure of the ram is clamped in the spindle box, and the cross-sectional area of the ram is small.

4 tool magazine

There are three basic types of tool libraries: turret type, drum type, and chain length type.

5 Attachment Headstock

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

6 CNC system

The CNC system generally adopts SINUMERIK840C and 840D from German SIEMENS company or 31I series from Japanese FANUC company, and the CNC axis adopts full closed-loop control.

7 Precision

The accuracy of a machine tool refers to its original accuracy without being subjected to external loads. Accuracy is usually represented by its opposite - the deviation from the ideal state (referred to as error), and the smaller the error, the higher the accuracy.

Gantry machining center

1. The operator should be familiar with and master the performance and characteristics of the gantry machining center machine. Ensure that the Kill switch can play a role quickly and effectively in case of emergency to avoid injury accidents.

2. Wear labor protective equipment according to regulations and strictly prohibit wearing gloves for operation.

3. When the equipment is working, do not touch the electronic switch with damp hands to avoid electric shock. Do not touch any moving parts with your hands.

4. Do not place tools or non machined workpieces on the gantry machining center or moving objects.

5. The computer desk or work desk next to the machine must be sturdy and cannot be placed on moving parts.

When moving up and down the workpiece, the machine should be stopped first and attention should be paid to maintaining an appropriate distance between the workpiece and the tool. During machine operation, please do not open the front door or left and right protective covers arbitrarily to avoid personal injury.

7. After completing the tool setting, please first run with DRY RUN to ensure that the program is correct.

8. After power outage or emergency stop, the three axes should be restored to their original mechanical position when shutting down.

9. Do not dismantle the travel switch or any related parts of the protective switch without authorization.

Before leaving the machine after finishing work, the control power switch on the operation panel and the main switch of the electrical box should be turned off.
