Discussion on the operation of the tool post of the CNC lathe

The CNC lathe is composed of CNC device, bed, headstock, tool post feed system, tailstock, hydraulic system, cooling system, lubrication system, chip conveyor and other parts. It can be equipped with the following two tool holders: a dedicated tool holder, which is developed by the lathe manufacturer itself, and the tool holder used is also a dedicated tool holder. The advantage of this tool holder is low manufacturing cost, but lacks versatility. General-purpose tool post, the tool post produced according to certain general standards, the lathe manufacturer can choose and configure according to the functional requirements of the CNC lathe. Today we are going to discuss the operation of the tool post of the CNC lathe:

  • 1. The tool post is off-position, overshooting or not rotating: The mechanical cause of this failure is more likely, mainly because the backing device does not work. First check whether the back positioning pin is flexible and whether the spring is fatigued. At this time, the positioning pin should be repaired to make it flexible or replace the spring. Secondly, check whether the connection between the rear ratchet and the worm is disconnected. If it is disconnected, replace the connecting pin. If the overshoot still occurs, it may be because the tool is too long and heavy. You should replace the positioning pin spring with a slightly larger elastic modulus.
  • 2. The knife holder is not locked tightly: the position of the sending plate is not aligned, remove the top cover of the holder, rotate and adjust the position of the sending plate, so that the Hall element of the holder is aligned with the magnetic steel; check whether the signal in place is sent , If there is no signal in place, it is the fault of the sender disk; you can check whether the elastic contact of the sender disk is worn out, whether the ground wire of the sender disk is open, poor contact or missed. At this time, it is necessary to replace the elastic contact or re-repair, and eliminate the line fault according to the contact status of the relay in the line, the contact status of the in-position switch, and the line connection status.

The above is the Taoist operation of CNC lathes. There are more news and information. Please continue to pay attention to the website. We will update relevant information from time to time for your reference, so stay tuned.
