Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

The seat position safety factor is different

Comfort and safety during driving are *important. Whoever has direct contact with our body is regarded as the seat. Comfort is not directly concerned with safety, but it also plays an important role indirectly. Therefore, whether it is to buy In order to drive more safely, we also need to know which position of these seats is the safest?

There are different positions in the car, but what we need to know is which position is safer. It seems to be a few simple positions, but there are still certain differences in the risk factor. Do you know these car owners? Whether you are a car owner or a passenger, it is necessary to know this common sense.

Location of the main driver:

When it comes to the position of the car, we first think of the position of the main driver, but the position of the main driver is relatively dangerous, and relatively speaking, the main driving position has to master the steering wheel, etc. The arms and legs are It is easy to get injured, so for the main driver, it is necessary to be equipped with safer at any time, like an airbag, and to develop the habit of wearing a seat belt at ordinary times.

The position of the co-pilot:

The position of the co-pilot is relatively *unsafe. Many car owners are puzzled. Why is this? According to reasoning, it should be the main driver, why is it the co-pilot? This is because the position of the co-pilot will just face the collision, and the position of the main driver just avoids this key point, so the co-pilot is *unsafe, so it is recommended that you try to avoid the co-pilot when riding in the car Position, pay attention to the location after riding, pay attention to it in time, and keep up with the safety measures accordingly.

Back row position:

This position is relatively safe. Why is that? Because the relative space in the rear is still larger, because the space for the owner to move is relatively large, when encountering danger, there will be a little more escape space, but also because the owner escapes, compared to the position of the main driver and the co-pilot. In this way, facing the dangerous situation directly, the position in the back row is relatively safer.

There are certain differences in the safety factor of the important positions in these vehicles. It is recommended that the owner choose the back row position as much as possible when riding in normal times to avoid the position of the co-pilot. If you are the owner, then the main driver should take corresponding protective measures. You must pay attention to it in time, and don’t leave hidden safety hazards due to momentary negligence. Protective supplies such as safety bags must be fully prepared at all times.
