Since the emergence of CNC lathes, there has been a dazzling array of programs and equipment that have been extended around them. Various connecting devices are overwhelming, and among these devices, automatic tool holders are more practical and widely applicable. They not only effectively save time for lathe tool holders, but also have great advantages in tool holder accuracy. Today, our CNC lathe manufacturer Haishu Machinery will explain to you the installation method and benefits of using automatic tool holders in CNC lathes.
Remove the cover on the knife holder and check if the position of the magnet and the transmitter disk is fixed. Check if the signal wire of knife 2 is sometimes disconnected and sometimes connected. Generally, a vertical four station system is used, and the center of the new tool holder should be consistent with the center of the original tool holder. Why use an automatic tool holder to modify a CNC lathe? Answer: There are CNC lathes with tapping, but I don't know if your CNC system has this loop command. If there is an automatic loop tapping command, you can try using your CNC lathe to simulate machining and tapping by keeping a safe distance from the workpiece when aligning the tool (not too far, leaving a safe distance for tool retraction) without installing the tool.
Except for drill bits and reamers which are mounted on the tailstock, are all other cutting tools mounted on the tool holder. No, sometimes drill bits and cutters are also installed on the tool holder, and sometimes deep hole chamfering cutters or die taps are also installed on the tailstock. Do the tailstock also need to be aligned? It is necessary to align the tool, but the tool holder does not necessarily have to align with the movement command of the (mechanical coordinates) tailstock. The rotary tool holder used in CNC machine tools for tool changing is the simplest automatic tool changing device, which includes square tool holders and hexagonal tool holders, that is, four, six or more tools are installed on them. In theory, it is possible, but in practice it is not, because the feed of CNC is controlled by a motor, which largely affects the accuracy. The signal for stopping the rotation of the 8-station hydraulic tool holder is different between manual and automatic modes. In manual mode, the tool holder motor stops rotating at a fixed angle every time it rotates [proximity switch detection], then locks and detects the tool position. In automatic mode, the tool holder rotates until it reaches the proximity switch of the selected workstation before the tool holder motor stops.
The reason why the speed of the CNC lathe turret tool holder slows down in automatic mode is that we first need to check if there is a fault alarm. If not, it may be a programming problem or a magnification switch adjustment. Check the program to see how fast the turret rotation speed is set, and make some changes. When modifying a CNC lathe with an automatic tool holder, it is possible to use it without changing the parameters. When programming with a rotary tool holder, T11T22T33T44 is usually used. When adding a row of knives, T11T22T33T44 is used. When using a row of knives, first determine which knife on the tool holder belongs to the younger brother. If it is a ground knife, then the knife cannot be replaced with a 1234 knife. That's all for programming.
The above is the installation method and benefits of using an automatic tool holder for CNC lathes compiled and released by the CNC lathe manufacturer Haishu Machinery. We hope that the above explanation can be helpful for everyone when using CNC lathes in the future.
