Fault repair of CNC lathe tool holder

The application of numerical control technology and CNC machine tools has successfully solved some automation problems of small-to-medium-sized parts with complex shapes and high consistency. This not only greatly increases production efficiency and processing accuracy, but also reduces the labor intensity of workers. Shortened the production preparation cycle. However, during the use of CNC lathes, CNC lathes will inevitably cause various failures, so the maintenance of faults has become the most critical issue for CNC lathe users. On the one hand sales company after-sales service can not be guaranteed in a timely manner, on the other hand to grasp some of the maintenance technology can quickly determine the fault, shorten the maintenance time, let the equipment operate as soon as possible. In daily failures, we often encounter problems such as tool holders, spindles, thread processing, system display, drivers, and communications. The knife rests a large percentage of them. Here, the breakdown describes the four-station electric knife heads encountered in daily work and various types of failures and corresponding solutions, hoping to provide some useful reference for everyone. The CNC system used is the GSK series lathe CNC system produced by Guangzhou CNC Equipment Co., Ltd.

Failure phenomenon 1: electric knife holder lock is not tight

Cause of failure

1 The position of the sending tray is not aligned: remove the top cover of the knife holder, rotate and adjust the position of the sending tray, align the Hall element of the knife holder with the magnetic steel, and make the knife position stop at the exact position.

2 system lock time is not long enough: adjust the system lock time parameters can be (new tool holder lock time t = 1.2s can be).

3 mechanical locking mechanism failure: disassemble the knife holder, adjust the machine, and check whether the positioning pin is broken.

Symptom 2: The cutter number of the electric tool holder keeps rotating, and the remaining cutter positions can rotate.

Cause of failure

1 The Hall element of this position knife is damaged: Confirm which tool position makes the tool holder turn non-stop, input the instruction to rotate this position on the system, use the multimeter to measure whether this position signal contact has voltage change to the 24V contact, If there is no change, it can be determined that the position of the knife Hall element is damaged, replace the sending disk or Hall element.

2 The signal line of this knife position is disconnected. As a result, the system cannot detect the bit signal: Check whether there is a disconnection between the tool signal and the system connection.

3 The system's location signal receiving circuit has a problem: When the Hall element of this location is determined to be no problem, and the connection between the location signal and the system is no problem, the mainboard is replaced.

1.5 Ton Pedestrian Type Electric Stacker

Zowell 1.5ton standing on Electric Stacker, is an industrial device for loading and lifting pallets on a shelf at high level. As an ideal choice to operate in narrow space of warehouse, it can be widely used in petroleum, chemical, pharmaceutical, textile, pigment, coal and other industries, as well as ports, railways, freight yards, warehouses.

Compared with the traditional manual stacking, Zowell full electric stacker maintains great advantages in safety, efficiency and cost. In addition to durability and accuracy both outside and inside, Zowell XE electric stackers are also equipped with mast with clear view, double speed and lateral vertical moving switch, which are valuable when working in limited space.


Detail features

1. Multifunctional handle
The multifunctional handle is imported from Germany. It has integrated control functions including a speed button, horn button, emergency reversing button and lifting button. The handle has an emergency reversing button which can effectively protect the operators from being hurt in accident involving falling items. The handle can realize braking both in vertical and horizontal position. The human-machine design is quite safe and the operation is more comfortable.

2. Strong power
This stacker adopts high efficiency motor which can be precisely controlled and the output power is strong. The turning control can be optionally equipped with EPS. It can help the driver with turning by using electronic control device to produce auxiliary power of relative level and direction according to the torque signal and speed signal. So the operation of the driver can be more convenient and precise and the movement can be more stable and reliable.

3.Superior gradeability
The powerful motor and 5 wheel stacker structure can provide superior stability and gradeability, so that the truck can have sufficient gradeability when it is fully loaded.

4. Buffered pedal
The foldable pedal can save space when the stacker is not in use. It can also effectively protect the drivers from being effected by the bumping and give feedback to the driver with the road condition.

5. Dual balance wheel device
This stacker is equipped with a dual balance wheel so that it can overcome roadblocks easier and the running can be more stable.

6. Emergency power-off switch
The power can be rapidly cut off in emergency to ensure safety.
