The abrupt stop switch

Emergency stop switch belongs to the main order control electrical appliances, when the machine is in danger, through the emergency stop switch to cut off the power, so that the machine stops running, in order to achieve the purpose of protecting the safety of people and equipment. The emergency stop switch is generally a manually controlled press switch, which can enter the control circuit of the equipment in series. The power supply of the control circuit is directly disconnected when the CNC machine tool is manufactured in an emergency shutdown, so as to avoid the abnormal work of the equipment when it is shut down.

The fuse.

Fuze is the most simple and effective protection of electrical appliances widely used at present. This usually includes a melt, a melting base. It is usually made of alloy material with lower melting point and better electrical conductivity, which acts as a protection circuit on machine tools.

In view of some customer response CNC lathe with FANUC0TD supporting the startup, found that CNC machine tool inlet hydraulic station abnormal sound, resulting in the hydraulic chuck can not be normal clamping problem, now notice as follows:

Fault Analysis of Hydraulic Chucks in Digital Control Lathe

Through on-site observation, it is found that abnormal sound occurs when the CNC lathe starts the hydraulic pump, and there is no hydraulic oil output in the output part of the hydraulic station. Therefore, it can be concluded that there is abnormal in the hydraulic station. The reasons for the failure may be as follows:

The hydraulic oil in the oil tank of the hydraulic station is too little, resulting in the lack of oil in the hydraulic pump.

The hydraulic oil in the oil tank of the hydraulic station has not been replaced for a long time, and dirt enters the oil tank, causing the hydraulic oil to fall into disrepair and produce abnormal sound.

Because the output tubing of the hydraulic pump station is blocked somewhere, the hydraulic impact is produced and a sound is made.

Four, the hydraulic pump and the hydraulic motor when the connection is loose, make a sound.

Five, hydraulic pump damage.

Hydraulic motor bearing is damaged.
