Introduction of CNC wire cutting principle and development history of industrial safety machining machine
Choose places without dust, avoid the flow next to numerous channels
(1) the characteristics of the wire cutting machine itself, the presence of dust in the air, will make the machine screw by serious wear, thus affecting the service life
(2) cnc wire-cut machine belongs to computer control, computer used disk on the air dust requirements is quite strict, when the dust into the disk, the disk will be damaged, also damaged hard disk
(3) the wire-cut motor itself emits a lot of heat, so the electrical cabinet needs frequent ventilation, if there is too much dust in the air, it will accumulate on the electrical components in the ventilation process, resulting in poor heat dissipation of electrical components, resulting in the circuit board burned out. Therefore,, the machine dust screen to often clean.
Choose areas with low temperature variations and avoid direct sunlight through Windows and roof panes and close to heat flow
(1) high precision parts processing products need to be under constant temperature, CNC wire cutting generally at room temperature 20C
(2) because the cnc wire cutting machine itself produces considerable heat when working, if the temperature change is too big, it will have a serious impact on the service life of the machine.
Select shielding room: because the process of wedm is an are discharge process, strong electromagnetic waves will be generated during the arc discharge process, which will cause harm to human health and affect the surrounding environment.
Choose a spacious plant with good ventilation so that operators and machine tools can work in the best conditions.
Handling:
1. Selection of handling methods: forklift and roller lifting are adopted for wire-cutting and edm equipment. In special cases, lift lifting is adopted
2. Locking before handling: the bed and each axis must be locked with special random fixings before handling. In order to prevent the handling of equipment damage, thereby affecting the accuracy of the machine and even make the equipment scrapped.
CNC wire cutting operation is safe: in order not to damage the machine tools and personnel, the following matters should be noted when operating the wire cutting equipment.
1. Only persons trained in such machinery and equipment shall be permitted to use such machinery and equipment.
2. In order to avoid the processing liquid and electrical cabinet overheating, the cooling system must be in a continuous state
3. In order to avoid direct contact with the power line, must close the protective door
4. Do not allow two people to operate the same machine at the same time, in the operation of the screen, should try to reduce the screen brightness, and select squint to observe the screen, so as to reduce the screen radiation to the eyes
5. Processors should be familiar with the specific function of each key-press operation panel and use the status, flexible to use in the process of the operation of the machine, familiar picture transformation, especially several important images (e.g., prepare the picture, see images) with the function, avoid caused due to not familiar with the operation panel in processing all kinds of anomalies, the other for each key (key) is commonly used especially high intensive use easily damaged, so when the operation panel, surface should be attached with a layer of plastic for protection, to extend the life of the operation panel
6. Like the operation panel, the processor should be familiar with the specific use of the remote control, the remote control keys should be protected by a layer of plastic paper, in addition, the remote control can be separated from the operation panel for remote operation, is the use of a wire for transmission, so the protection of the remote control should also include the protection of the wire. CNC wire cutting in the process of using not to pull the wire, so as to avoid the remote control failure, part of the wire should be placed in the circle, after use, be sure to put back to the original hanging well
7. During machine tool or head movement, never put your fingers between the head and the work; prevent safety accidents caused by wrong command input or wrong direction key pressing
8. Protection of processing platform: when processing workpieces, pay attention to whether the clamping method will hurt the processing platform, blow dry the platform when the machine is in use, protect the machine with anti-rust oil when not in use for a long time
9. In the workpiece erection process, should pay attention to whether the cutting will hit the upper and lower head, for the hole processing should be used special processing technology, to avoid the waste can not be removed caused by card, affect the accuracy of the machine tool
10. The workpiece clamping to be convenient and stable as the principle, in erecting the workpiece pressure to the workpiece is not water impulse as the principle, so as not to cause screw slip cannot be removed
11. In daily work, we often encounter workpieces that cannot be machined by using the general die setting method, so we must use special clamping jig
(1) small workpieces -- if the pressure plate cannot be set up, please consider using hornbeam or malt for processing
(2) in the case of large inclination type workpiece - unable to tilt processing, should be used sinusoidal table or tilt pad block assisted tilting processing method for processing
(3) multi-piece processing -- it can be considered to use the positive Angle device or malt stone for overlapping processing
(4)CNC wire cutting should ensure that the jig is not damaged during the use of the jig (for example, it is not feasible to hurt the jig during cutting for the convenience of mold setting).
