"Look, smell, ask, cut" four steps to deal with CNC machine tool maintenance problems

In order to improve the use of CNC lathes, the integration of CNC lathe maintenance principles, this article discusses the general way of maintenance for CNC lathes. I will summarize it as "look, smell, ask, cut" four methods.

1、Looking

That is, the use of human sensealuminum prototype machining organs such as hands, eyes, ears, nose, etc. to search for the cause of the fault. This is one of the simple and direct methods.

When there is an abnormality in CNC lathe, first of all, find out the fault phenomenon, how it happens and the process of it. If the fault can be reproduced, the process of the fault should be observed and checked, and only when the first-hand situation is mastered, it will be beneficial to clear the fault.

At the same time, observe whether there is reflective damage; and whether there are no burn marks, resistance and wire discoloration long ago; running and sealing position there are no abnormalities, such as spills, shedding, spillages, oil, smoke, sparks, etc.; circuit breakers, relays, whether the fuse is fused; whether the machine power is out of phase, whether the three phases are seriously uneven across, whether the machine voltage is normal; electrical components in the parts have whether the parts in the electrical components are off, disconnected, stuck, loose joints and other conditions; whether the switch is suitable; whether the operator's processing procedures are correct. This step is very intuitive for the maintenance of CNC lathe testing, but also very test the maintenance of the machine tool hardware structure to understand the extent of the step.

2、Smell

Identify whether there is an odor. When the machine tool moving parts occur violent friction, the electrical insulation layer will burn, and at the same time will produce oil, smoke, gas, and its insulation material scorching smell; when the machine tool discharge will produce ozone smell, but also hear the discharge sound.

3, ask

That is, ask the condition of the machine when the failure occurs. In CNC processing, it is best to develop strict management measures, requiring operators to make detailed records when encountering faults. This can prevent the occurrence of failure when the maintenance staff is not in the vicinity and can accurately reflect the specific circumstances of the failure. When a fault occurs on a CNC lathe, the machine is first terminated and the site is protected, and the operator carries out as detailed a record of the fault as possible, in which the key information is observed and recorded in detail.

For example: the condition of the fault, aluminum sheet metal fabricationthe location of the fault, and its failure when the state of the machine tool and control system conditions. If the fault occurs in the automatic processing method, the processing program number when the fault occurs, the program segment number where the abnormality occurs, the tool number selected for processing and other specific information should be recorded. In case of a failure such as machining accuracy deviation or too much contour deviation, the machined workpiece number should be recorded and the failed workpiece should be saved for specific analysis. In the event of a failure, if the system has an alarm indication, the alarm status and alarm code of the system should be recorded. If the failure occurs when processing parts, it should be recorded when processing the same kind of workpiece, such as the probability of failure status.

4、Cut

That is, for the fault condition to diagnose, and then carry out maintenance, this step is also the most important step in the maintenance of CNC machine tools.

What is a machine prototype?

Before a larger quantity of parts is needed, a smaller batch of parts can be created using the prototype machining method. Companies may use prototype machining for a variety of reasons, such as checking to determine if a product will function as planned and determining exactly how a part will look when it is produced.

What do fabricators of sheet metal do?

The term "sheet metal fabrication" refers to a variety of techniques used to construct machines and other structures out of sheet metal. It may be a difficult task requiring the assistance of numerous specialists. Fabrication shops, or fab shops for short, are companies that specialize in the fabrication of sheet metal.

Is it challenging to process aluminum?

Aluminum is a material that can be worked rather easily. As long as you comprehend the three criteria that determine the machinability of the metal, it is also rather simple to succeed in this work. The actual machining process itself is the first element.
