CNC machining center structure

1. Basic components of CNC machining center:

It is mainly the structural basis of CNC machining, composed of the bed, column and table, etc., they mainly bear the static load of the machining center and the cutting load generated in the processing, so it must have enough stiffness. These large pieces, which can be cast iron or welded structural steel, are the largest parts in the machining center by volume and weight.

2, CNC machining center spindle part:

The spindle can include spindle box, spindle motor, spindle and spindle bearing and other parts. The start, stop and speed change of the spindle are controlled by the NUMERICAL control system, and through the tool mounted on the spindle to participate in the cutting movement, is the cutting power output components. Machining center is the key component, it determines the machining accuracy and stability of the machining center.

3, CNC machining center automatic tool change system:

By the knife library, manipulator, drive mechanism and other components. When the need to change the knife, the CNC system issued a command, by the manipulator (or by other means) will be the tool from the knife library out of the main shaft hole. It solves the task of automatic storage, selection, handling and exchange of cutting tools between working procedures in the multi-process continuous processing after a workpiece clamping.

Knife store (cutter head) is a device for storing all the tools used in the process of machining. Knife library has disc, chain and so on, the capacity from a few to several hundred. The structure of the knife arm according to the relative position and structure of the knife library and the main shaft, there are various forms such as: single arm type, double arm type and so on. Some machining centers do not use the tool arm and directly with the spindle box or knife library to achieve the movement of the tool.

4, CNC machining center CNC system:

The cNc part of the machining center is composed of cNc device, programmable controller PLC, servo drive device and operation panel.

5, CNC processing center auxiliary facilities:

Including lubrication, cooling, chip removal, protection, hydraulic, pneumatic and detection systems and other parts. Although these devices are not directly involved in the cutting movement, but machining center machining efficiency, machining accuracy and reliability plays a role in the guarantee, so it is not the lack of machining center part.

6, CNC machining center automatic tray exchange system:

In CNC machining center our automated or further shorten the processing time, adopting multiple automatic switching work platform reserve artifacts, a workpiece on the workbench installation process at the same time, the other one or a few workbench can also load and unload the other parts, when after completing a workbench parts processing, automatic switching table, with new parts processing, This can reduce auxiliary time, improve processing efficiency.
