Data Lathe: introduction to the Classification of tool Library of NC Machining Center.
The classification basis of the tool library of NC machining center.
In order to change the tool in the NC machining center, not only the tool holder but also the tool library can be used to realize the tool change process.
The main power of the tool library comes from the motor and hydraulic system to provide transmission power, and the positioning unit is used to ensure that every replaced tool and tool sleeve can rely on quasi-stop.
The CNC machining center is fully closed and protected, the working procedure is centralized, and the machining process is continuous.
The automatic tool changing process can be easily realized by using a variety of tools, and the workbench can be changed automatically by using a variety of worktables.
At the same time, the NC machining center also has strong functional support and tends to compound machining.
High degree of automation, high precision and large sales volume.
Under appropriate circumstances, greater benefits can be brought into play.
According to the specific structure, it can be divided into three forms: vertical type, horizontal type and door type.
The difference between CNC machining center and other CNC machine tools is that CNC machining centers have tool libraries and automatic tool changing devices, while other CNC machine tools do not have tool libraries and automatic tool changing devices.
This is the difference between NC machining center and other CNC machine tools, and it is also the advantage of NC machining center.
With the automatic tool changer and tool library, the workpiece can be clamped at one time without manual operation, and multiple processes can be completed automatically.
How to correct the accuracy of the guideway of NC milling machine?
When using CNC milling machine, users will encounter the problem of unstable precision of guideway.
At this time, they need to repair the guide rail of the CNC milling machine in time.
In the process of maintenance, we need to pay attention to three major problems, so as not to cause damage to the guideway, resulting in the normal operation of the CNC milling machine.
So, how to correct the unstable accuracy of the guideway of the NC milling machine?
First of all, the mechanical strength of the repair layer itself and the actual working environment of the guide rail are considered.
For CNC milling machines with different standards, different performances and different operating environments, appropriate welding and pasting data, advanced correction methods and new processes should be selected during maintenance.
Second, it is necessary to consider whether the selected correction process has any effect on the accuracy and mechanical properties of the guideway.
If affected by temperature, it will not cause the deformation of the guide rail, will it change the mechanical strength and external hardness of the guide rail and so on.
Third, the adaptability of the selected correction process to the guideway data should be considered.
For example, cast iron data of the guide generally do not need cast iron surfacing.
Due to the poor weldability of cast iron, it is easy to produce cracks, pores and other defects, so it is not suitable for processing.
