As an important component of CNC turning lathe machine cutting processing, the tool holder is related to the processing quality and efficiency of the product. Once a fault occurs, it may cause the product to be unqualified or even scrapped, bringing significant economic losses to the enterprise.
CNC turning lathe machines analyze the types and frequency of tool holder failures, and analyze and eliminate high-frequency failures, aiming to facilitate operation and technical personnel to improve work efficiency and reduce enterprise production costs. Let Deed CNC turning lathe manufacturer summary for you.
In the cutting process of CNC turning lathe machines, the rotary tool holder common failure.
The top 3 failure rates are tool holders not rotating to the correct position, signal errors indicating a incorrect tool holder position, tool holders being able to rotate but not being able to lock in place, tool holders being able to rotate but not being fixed in position.
The main types of failures are electrical, mechanical, and parameter failures.
For frequently occurring failures, analyze and summarize them, and develop troubleshooting mechanisms.
Organize troubleshooting knowledge training. Through training, the operator has the ability to handle simple faults (such as tool holder loosening, tool holder reverse rotation, etc.) to reduce the intermediate links of reporting and repair stoppages, and improve the equipment utilization rate.
Encourage employees to solve problems themselves and provide technical and financial support for technical improvements. Encourage employees to solve problems encountered in daily production (such as tool holder failures) and provide technical guidance and financial support. Treat problems as opportunities, work with technology improvement departments to improve efficiency, and improve knowledge and skills.
Establish relevant maintenance mechanisms and warranty platforms, encourage employees’ "grab" style maintenance to improve work performance. Based on data analysis, the top three types of failures that often occur are analyzed for troubleshooting, and corresponding solutions are provided.
Failure
The CNC turning lathe machine tool holder does not rotate to the correct position (the system will generally indicate a signal error indicating a incorrect tool holder position).
Reason analysis
The three-phase wiring of the tool holder power supply is connected incorrectly, or there is a power supply failure;
The tool holder relay is disconnected after overload and a fault occurs, causing the thrust ball bearing on the central axis of the tool holder to be crushed by the axial positioning plate, and the bearing cannot rotate, so the motor cannot drive the tool holder to rotate.
Exclusion measures
Check the circuit, pay attention to safety protection, disassemble the tool holder, adjust the clearance of the ball bearing, replace damaged parts, tighten each screw; check the 24V power supply and each phase wiring, replace part of the "system location plate" button.
Failure
The tool holder can be rotated but not locked in place, and the reason for the failure is analyzed.
If the tool holder can be rotated, it indicates that the power supply and phase are normal.
The initial position of the screw used to lift the tool holder is incorrect (it cannot match the groove on the tool holder worm wheel);
The restored position is also incorrect (the screw protrusion and the groove should be embedded to a suitable depth, so that the lifting and lowering heights of the tool holder are the same), which makes it impossible to lock the tool holder in the specified position after rotation.
Exclusion measures
Check the circuit, pay attention to safety protection, disassemble the CNC turning lathe machine tool holder, adjust the initial position of the bolt rod protrusion and the groove on the worm wheel.
Failure
The tool holder can be rotated but is not fixed in place.
Reason analysis
Checking whether the Hall element inside the tool holder is damaged;
The CPU board in the control system has a fault or the position signal board has a fault.
Exclusion measures
Check the static parameters and dynamic parameters of the Hall element. If the parameters do not meet the requirements, replace them;
Check the two boards. If they are abnormal, replace them.
